Starvation Mode: Is It A Myth? Is It Real? Is Your Body In It Right Now?

Let me guess. You want to lose weight, right? If so, then you have something in common with the majority of the population. Most of them want to lose weight, too.

But if you’re here to learn about starvation mode, then I can assume there’s something else you probably have in common with the majority of the population: you’re NOT actually losing weight.

You want to. You’re trying to. But, it’s just not happening. Sound about right?

And that’s probably why you’re here. You want to know why it’s not happening. Well, I can tell you straight up that there’s only one legitimate reason for why a person fails to lose weight, and the good news is that by the end of this article, you’re going to understand it once and for all.

But here’s the bad news. Even though there’s only ONE true reason for why a person isn’t losing weight, there are dozens of excuses and reasons that a person will come up with and consider to be the cause that just aren’t actually true, accurate or even remotely based in reality.

I’ve been lucky (or unlucky) enough to have heard most of those excuses and fake reasons over the years, but I’ve found that there are two that seem to come up more often than the rest:

  1. Muscle Weighs More Than Fat. The thinking here is that the person isn’t losing weight because they’re building muscle. So while they ARE actually losing plenty of fat, they’re supposedly gaining plenty of muscle at the same time and it’s balancing out their weight on the scale (thus causing it to appear as though they’re not losing fat even though they are). They’re just building an equal amount of muscle at an equal rate.
  2. Starvation Mode. The thinking here is that the person isn’t losing weight because their body has entered a weight-loss-preventing (or sometimes even weight-gain-causing) state commonly referred to as “starvation mode.”

Now I’ve already covered #1 in detail before (Weight Loss Plateau Myth: Muscle Weighs More Than Fat?), and I can sum it up by saying no… it’s highly unlikely that you’re building so much muscle so quickly that it’s completely covering up/balancing out your fat loss. MUCH more likely: you’re just not losing any fat, period. The full details of why are explained here.

But what about #2? The dreaded starvation mode. Is it just a myth? Or is this one real? Let’s find out.

What Is Starvation Mode?

That depends. Do you want to know what it actually is, or what most people think it is? Big difference. Let’s start with the second one.

Most people’s definition of starvation mode goes something like this:

To lose weight, you need to consume less calories. BUT, if you consume TOO few calories, your metabolism slows down so much so that your body enters a state where weight loss stops completely.

Some people also believe being in this state of not eating enough calories not only prevents weight loss from happening, but it can also cause weight gain.

So basically, eating too little prevents your body from losing weight. In some cases, it might even cause it to gain weight. To get “out” of this state and start losing, you must eat more calories, not less.

This, according to most people, is what starvation mode is.

Now with all of this in mind, let’s pretend we have a person who says they’re “eating right” and “eating healthy” and “eating less” and knows for sure that they’re eating an amount of calories that SHOULD cause them to lose weight. But yet, they AREN’T losing any weight.

Based on the definition above, it would make perfect sense for this person to assume that they’ve clearly entered starvation mode due to eating too little/not eating enough. That has to be their problem, right?

I mean, that’s the only logical conclusion a person can come to in this scenario, isn’t it? I guess so.

Well, except for one tiny thing… this definition of starvation mode is bullshit.

Your Version Of Starvation Mode Is A Myth

Seriously. It’s not real. It’s a myth.

As long as you create a caloric deficit (meaning consume less calories than your body burns, or burn more calories than you consume… just different ways of saying the same thing), then you will lose weight every single time regardless of whether you’re creating a deficit that is small, moderate or large.

Even if your calorie intake is dangerously low (not recommended at all, just making a point), you will still lose weight.

There is no such thing as “I’m not losing any weight because I’m eating too little.” That’s horseshit. And there’s definitely no such thing as “I’m gaining weight because I’m eating too little.” That’s even bigger horseshit that I can only assume would require the presence of an even bigger horse.

And the idea that you skipped breakfast or waited longer than 3 hours between meals (or something equally meaningless) and have now instantly entered starvation mode as a result is too laughable to even warrant another second of discussion.

Create a deficit and weight loss will happen. Calories in vs calories out always applies, no matter how low the “calories in” part is (or really, how low you mistakenly think it is… more on that in a minute).

Simply put, what most people think of starvation mode to be is complete and utter nonsense.

And guess what? I can prove it. Guess what else? I can prove it with 4 different types of proof. Ready? Here we go…

1. Scientific Proof

The cause of starvation mode, they claim, is a huge drop in metabolic rate. Meaning, eating too little supposedly causes your metabolism to slow down to the point where it prevents weight loss from happening.

This is actually half true, which of course means it’s also half false.

Adaptive Thermogenesis

The true part is that being in a deficit DOES in fact cause your metabolic rate to slow down over time. This is known as adaptive thermogenesis, and it happens as a result of any prolonged deficit. The more excessive (in terms of size and duration) the deficit is, the more significant this drop will be.

The false part however is the idea that this “metabolic slowdown” is significant enough to actually STOP weight loss. It’s not. And it sure as hell isn’t significant enough to cause weight gain.

It’s mostly just enough to slow down progress a little over time. A much bigger factor slowing down weight loss progress over time is the fact that you’ve already lost a bunch of weight, so your body just isn’t burning as many calories as it initially was.

Meaning, your maintenance level has decreased because your body weight has decreased. So the calorie intake that caused lots of weight loss at 250lbs isn’t working as well (if at all) when you get down to 200lbs.

And it’s this successful decrease in overall body weight combined with that small (but real) amount of adaptive thermogenesis that causes people to eventually need to make adjustments at certain points so that weight loss continues happening (which, by the way, is a one sentence breakdown of what causes weight loss plateaus, why they’re common and normal, and what ultimately solves them).

It has nothing at all to do with “I’m eating too little and my weight loss stopped.” That’s nonsense, and literally every single study in existence supports this.

The Minnesota Study

Every controlled study where a deficit was created resulted in weight loss 100% of the time. Regardless of every other factor. A caloric deficit = weight loss. Always. Even in actual starvation studies like the often cited Minnesota Starvation Experiment.

In this study, 36 men were put on a 24 week long “starvation diet” consisting of two meals per day containing a total of 1560 calories, and that amount was then reduced further throughout the study to ensure weight loss kept happening

For these men, this represented a daily deficit of 50% below maintenance (compare that to a typically recommended “ideal” moderate deficit of 20%). Oh, and they all had to walk 22 miles per week as well.

Guess what happened? All of the participants lost approximately 25% of their starting body weight and reached about 5% body fat. So they were purposely (semi) starved for 6 straight months, and they all lost tons of weight/body fat.

Now For The Really Crazy Part

Ready for this one? This Minnesota Starvation Experiment is the study people sometimes use to show that “starvation mode” is real. I kid you not. This study, which clearly shows people eating very little and losing plenty of weight, is the same study idiots cite as an example of how eating too little stops people from losing weight.

A participant of the Minnesota Starvation Experiment.

A participant of the Minnesota Starvation Experiment.

How can this be, you ask?

Because at the end of the study, the men’s metabolic rates dropped by about 40% (two points about that: 1) only a small percentage of that 40% was actually the adaptive component, the majority was just due to the overall loss of weight, and 2) 40% still isn’t the 100% complete metabolic shutdown or whatever nonsense people think happens… but let’s play along anyway) and appeared to finally stop losing weight.

So after they already lost over 25% of their body weight and hit 5% body fat and looked deathly skinny (see pic to the right), they finally appeared to stop losing.

So stupid people see this and say “HA! See… starvation mode is real! Told you so! This is why I’m not losing any weight!!”

But a non-stupid person sees this and says “Uh, no. They all just finally reached a point where there wasn’t any weight left to lose without dying.”

Take a look at that picture. That’s one of the participants somewhere near the later part of this study. Is that guy in his current state a perfect example that starvation mode is real? That eating too little stopped him from losing any weight? Seriously? No. He’s a perfect example of the opposite… to the point where he literally lost as much weight as his body was capable of losing.

And yet you — someone who is likely a normal weight, overweight, or obese person NOWHERE NEAR THIS STATE who will NEVER BE ANYWHERE NEAR THIS STATE who’s trying to lose anywhere from 5 to 200 pounds of body fat to look prettier in your swimsuit — thinks this somehow applies to you? HA!

And even if you did reach a point like this (and I seriously hope that you don’t), your lack of weight loss is the least of your problems. The fact that you’re about to die is probably your new biggest concern.

2. Unfortunate Real World Proof

A reader recently brought up the subject of holocaust survivors in the comments of something I wrote about starvation mode. It’s obviously not an example I’m happy to use, but… it’s there, so I will.

And all it takes is one look at the pictures of how horrifically skinny the people in concentration camps were and you should have all the “real world” proof you need that what most people consider starvation mode to be (“I’m eating too few calories and it’s stopping me from losing weight/causing me to gain weight”) is pure nonsense.

Those people were consuming less calories than anyone ever would under any circumstance, and they all lost disturbing amounts of weight.

But yet you, a normal person under normal circumstances who is unable to lose weight have somehow come to the conclusion that YOU’RE eating so little that YOU’RE in starvation mode and that’s why weight loss isn’t happening for YOU? Ha!

Can you even comprehend how silly that thought is?

If that was even remotely true, wouldn’t those pictures of concentration camps show a ton of fat people who didn’t lose any weight (or maybe even gained some!!) because starvation mode kicked in and magically prevented weight loss from happening for them just like it’s supposedly preventing it from happening for you?

And they were all eating WAY less than you are (or at least think you are), so it would’ve surely kicked in even stronger for them, right? Yeah… sure.

And that would also explain why eating disorder clinics have so many “fat anorexics” coming in all the time. You know, the ones who failed to lose any weight whatsoever and remained at their normal healthy weight despite eating very little and purposely starving themselves? Yeah… sure.

3. Television Show Proof

Now for something less serious… reality shows!

I was going to go the Survivor route with this one, but I’ve been catching up on shows that have been sitting on my DVR for a while, one of which is something called Naked And Afraid.

If you don’t know what it is, it’s basically a more hardcore version of Survivor. Two people (a man and a woman) get dropped in some hard-to-survive remote location with little to no supplies (or clothes) and have to survive there for 21 days with no help of any kind (although producers eventually step in when it looks like someone might die… how nice!).

So if these two people want to eat, they need to catch/kill/cook something. And most of the time in the episodes I’ve seen, they have a CRAZY hard time catching/killing/cooking things and spend most of the 21 days not eating anything whatsoever and complaining about how they are in desperate need of food.

With me so far? Cool.

At the end of the 21 days, the show does a quick recap of what happened, which includes telling us how much weight the two people ended up losing. I’ve seen the man and the woman each lose anywhere from 20-50lbs during those 21 days of barely eating.

Still with me? Cool.

So tell me…

If most people’s definition of “starvation mode” is real, and eating too few calories STOPS people from losing weight or even causes them to GAIN fat… how the hell did these people who were eating insanely low amounts of calories still lose tons and tons of weight?

If most people’s definition of “starvation mode” is real, why doesn’t every episode end with a recap explaining that no one lost any weight whatsoever because they were eating too little and starvation mode kicked in?

If most people’s definition of “starvation mode” is real, why doesn’t every episode end with a recap explaining that the man and the woman both gained weight because they were eating too little and starvation mode kicked in?

Why? Because most people’s definition of “starvation mode” is bullshit.

4. Perfect Real World Proof

I told this story on the AWR Facebook page recently, but it’s such a perfect real world example that I have to include it here too. So, here it is…

A woman who needs to lose 85lbs tells me she’s been working out a lot and eating 1300-1500 calories per day. But yet, she’s not losing any weight! In fact, her clothes feel tighter! WTF?

She’s considering eating more calories, with the assumption being her calories must be too low (that darn starvation mode strikes again!!!). She has also considered the possibility that, since “muscle weighs more than fat,” maybe she’s just building lots of muscle and it’s hiding her fat loss results on the scale (her trainer actually told her this was the reason).

So I tell her this, because I’ve heard her story a million times before:

“When it comes to fat loss results, someone like you with 85lbs to lose should be seeing some degree of progress pretty much every single week. Your weight should be gradually and consistently decreasing at some realistic rate (0.5-2lbs per week, possibly even more at first). So if that’s not happening, and you haven’t lost a single pound in weeks/months, and your clothes actually seem to be getting tighter on you, then it appears that there isn’t actually a deficit present. Simple as that.

How can that be if you’re eating and burning as many calories you say you are? Well, more than likely, you’re somehow miscalculating or underestimating your calorie intake (the most common cause), miscalculating or overestimating calories burned, or a bit of both.”

This is typically the point in the conversation where the person gets mad at me for insulting their intelligence. Luckily, this woman didn’t. The next day, she responded with this:

“I wanted to tell you after considering what you said (and it was hard not to react defensively… in my head I’m saying I KNOW I’ve been sticking to my diet religiously and haven’t miscalculated) but after that initial reaction I started to examine even more closely after reading your guides and understanding a little better.

The Weight Watchers program uses points. The points equate to about 50 calories each. I get 26 points a day and earn extra points based on my exercise so I was (I thought) taking in from 1300 to 1550 calories a day (less than what I figure I need based on your maintenance calculator).

So in looking at the program all fruits and vegetables are free, meaning no points to encourage one to eat more fruits and veggies. So I have been eating large salads and at least three fruits every day that I don’t count for! That’s at least an extra 300 calories or more a day not being counted!

Plus I noticed I pour a little nonfat milk in my morning coffee. I never count that because it’s just a dab but today I measured it and its about a qtr cup or another 22 calories.

Oh yeah, let’s not forget the frozen berries I add to my protein drink each morning… more free uncounted calories! Amazing!!!! I’m quitting Weight Watchers today to follow your plan. Will see if I can find a good calorie counting app and count everything.”

Happy for her? Definitely. Surprised? Not even a little.

A few days later, she checks back in with an update…

“Hi there. Just wanted to touch base after my first week following your guide to thank you. After getting my calorie deficit accurate I dropped 2.6 lbs this week!

I know that won’t seem like such a big deal to your readers but it’s everything to me. I don’t need to adjust my thyroid meds and for the previous 6 weeks of killing myself 6 days a week at the gym and sticking to Weight Watchers I lost, if lucky a half pound and just couldn’t figure it out… didn’t know what was wrong and was soooo discouraged.

I have a long way to go (another 75) but now I know I can stick to it thanks to you helping me see how to actually get results! You are an angel. Thank you, thank you, thank you! Thank you for helping others cut through all the confusing crap!”

So what’s the moral of this story? Besides the fact that I’m an angel? It’s pretty simple…

If you’re not losing any weight over a significant period of time, it’s not because your calories are too low, or because you’re in starvation mode, or because muscle weighs more than fat, or because of carbs, fat, meal frequency, meal timing, food choices or any other crazy voodoo bullshit.

It’s because there is no deficit. Even if you think there is… there isn’t. If there was, you’d be losing weight.

An Updated Update

Literally the day before posting this article, that same woman sent me an update…

Just checking in. Since following all your great advice I’m 18 lbs down! 67 to go but thanks to you I know I will be successful this time. You are literally a lifesaver. Thank you for doing what you do. Will let you know when I reach my goal just thought you might want to know I am still progressing!!

Music to my ears.

Something Real: The Starvation Response

Alright, so by now I’ve hopefully helped you see that the typical definition of starvation mode is nothing but a silly myth and a convenient excuse people pull out of their ass to try to explain their lack of weight loss.

In reality, the real explanation is that they’re just failing to do what needs to be done (e.g. create a caloric deficit). Simple as that. Additional details here: How To Lose Fat

But, there is something else that needs to be mentioned here which happens to be very real. It’s something better described as the “starvation response.

Basically, if you do things to your body that it doesn’t like, it’s going to respond in whatever way makes the most sense to it from a survival standpoint.

In this case, the thing your body doesn’t like is an extreme and prolonged deficit caused by either severe caloric restriction (you know, VERY low calorie diets), excessive amounts of exercise (often tons and tons and TONS of cardio on a daily/almost daily basis), or some combination of the two (very few calories coming in with very high calories going out).

In this sort of extreme scenario, your body’s adaptive response is to make it harder for you to allow this to continue and, you know, prevent you from dying. How so? Well, for starters…

  • It slows down your metabolic rate, aka the adaptive thermogenesis I mentioned earlier. Since your body can’t tell the difference between you eating less in an attempt to lose fat and look good, and you eating less because you’re about to starve to death, it reacts to both scenarios the same way… by slowing down your metabolic rate in an attempt to conserve energy stores and keep you alive. This IS completely real, and the exact amount of it will vary from person to person. However, as mentioned earlier, this amount of “slowdown” is MUCH less than most people think. It’s enough to slow weight loss progress a little over time, but no where near enough to completely stop it or prevent it from happening in the first place (and certainly not enough to somehow cause a person to gain weight).
  • It reduces the amount of non-exercise activity thermogenesis (NEAT) taking place, which in turn causes you to naturally burn less calories. This is really part of the previous bullet point.
  • It causes intense hunger and food cravings, which causes you to eat more than you’re attempting to. Pay extra attention to this one. Think of the people who starve themselves most of the week with some stupid 800 calorie per day diet, then binge like crazy during a 1-2 day span afterwards. They’ll say “I’m eating 800 calories per day and not losing weight… it has to be starvation mode!!” Nope. First of all, most of those people are unknowingly eating more than the 800 calories they claim. Second, the few that legitimately are eating 800 calories most of those days are following them up with those 1-2 day binges where they essentially binge-eat themselves right out of the excessive deficit they stupidly attempted to create during those previous days. So… stupid 800 calorie starvation diet most days + crazy 3000-6000 (or more) calorie binges on other days = no deficit present (but maybe a surplus now is). And that’s magically how someone “eating 800 calories per day” ends up not losing weight or possibly even gaining some. They’re either unknowingly eating much more than they claim, or eating what they claim on some days and then binge eating themselves right back to their maintenance level and then some on the others.
  • It makes you feel like crap mentally and physically. Pretty self explanatory.

This, among many other obvious health reasons (plus the increased risk of muscle loss, the fact that the weight is often regained right after, the likelihood of an eating disorder developing if it hasn’t already, etc.), is why you’re NOT supposed to severely restrict your calorie intake and/or do extreme and excessive amounts of exercise.

Doing so would be stupid.

But, here’s the thing. Even if you did do something this stupid… you’d still lose weight. Every single time in fact. Every study and real world example proves it, and there is not a single bit of evidence anywhere that suggests otherwise.

BUT PLEASE NOTE: I say this only to help show you that the concept of “eating too little preventing weight loss/causing weight gain” is bullshit, not to suggest you actually start starving yourself to lose weight. I’m NOT suggesting that at all. It’s a terrible idea. I don’t recommend it at all. You shouldn’t do it. Don’t do it. Don’t be stupid. Have I said this enough times to sink in for the handful of people looking for someone to justify their eating disorder?

Just in case I haven’t, here’s one last thing about the Minnesota Starvation Experiment I mentioned before. Yes, they all lost weight on very low calorie diets. But, some pretty fucked up shit (technical term) happened as well…

Among the conclusions from the study was the confirmation that prolonged semi-starvation produces significant increases in depression, hysteria and hypochondriasis as measured using the Minnesota Multiphasic Personality Inventory. Indeed, most of the subjects experienced periods of severe emotional distress and depression. There were extreme reactions to the psychological effects during the experiment including self-mutilation (one subject amputated three fingers of his hand with an axe, though the subject was unsure if he had done so intentionally or accidentally).

Participants exhibited a preoccupation with food, both during the starvation period and the rehabilitation phase. Sexual interest was drastically reduced, and the volunteers showed signs of social withdrawal and isolation. The participants reported a decline in concentration, comprehension and judgment capabilities, although the standardized tests administered showed no actual signs of diminished capacity. There were marked declines in physiological processes indicative of decreases in each subject’s basal metabolic rate (the energy required by the body in a state of rest), reflected in reduced body temperature, respiration and heart rate. Some of the subjects exhibited edema in their extremities, presumably due to decreased levels of plasma proteins given that the body’s ability to construct key proteins like albumin is based on available energy sources.

Think of this as the starvation response at its absolute worst (which is consistent with what accompanies anorexia). The lesson? Very low calorie diets will cause weight loss, BUT DON’T ACTUALLY DO IT.

Another thing worth mentioning is that some degree of starvation response comes about during ANY form of consistent deficit, even the small/moderate/safe kind that is recommended. It’s just to a less significant and noticeable degree than when the deficit is excessively/stupidly large.

This is one of the many reasons why A) a small/moderate deficit is recommended in the first place (it’s safer, healthier, easier, more sustainable, less problematic, etc.) and B) things like refeeds, diet breaks and cyclical forms of dieting are recommended for people trying to reach lower levels of body fat and/or those who will just be in a deficit for a significant period of time… to help prevent, reduce and fix the various issues associated with this starvation response.

Although again, just keeping your deficit to a sane size and your activity to a sane level will alone go pretty far in reducing these issues for the average fat person trying to become less fat.

So yes, the starvation response is a real thing that does affect people losing weight. And yes, the more extreme your deficit is, the more extreme the response will be. This is all true and legit.

BUT… it’s STILL not what “starvation mode” is thought to be. It STILL doesn’t prevent weight loss. It STILL doesn’t cause weight gain. That STILL remains total horseshit just the same.

The starvation response will basically make weight loss harder and possibly slower at some point, and some adjustments may need to be made to compensate. But actually stop weight loss from happening or reverse it? Nope. That just doesn’t happen.

If It’s Not Starvation Mode, Then Why Aren’t I Losing Weight?

If weeks/months are passing and you’re not losing any weight (or you’re possibly even gaining some), and you came to the incorrect myth-based conclusion that you must be in starvation mode, then I hope you realize by now that you were wrong.

And that brings us to our next obvious question. If “starvation mode” isn’t the cause of your lack of weight loss… just what the hell is? Well, if you made it this far, that answer should be pretty obvious by now.

It’s not because you’re eating too little. It’s not because your calories are too low. It’s not because you’re burning too many calories. It’s the opposite.

Basically, you’re eating more calories than you think you are, burning less calories than you think you are, or both… and no deficit is present.


I know, I know… “But I’m only eating X amount of calories, I swear!” You know who else swore they were “only eating X amount of calories” (with X being some low amount that should clearly cause weight loss)? The woman in my story from before.

You remember her, she was the woman who claimed to be eating 1300 calories per day until she realized she wasn’t. Instead, she was accidentally underestimating, under-reporting, and/or just miscalculating her calorie intake by hundreds of calories per day the whole time.

Just like pretty much everyone else who swears they’re “eating the right amount of calories” and “working out to burn the right amount of calories” but yet somehow STILL aren’t losing any weight for some crazy reason.

That “crazy reason” is just the simple absence of your required caloric deficit caused in these cases by an underestimated calorie intake, an overestimated activity level, or just some kind of miscalculation or mistake somewhere that has lead you to believe you’re “doing everything right” when in reality you are not. (Additional details here: Why Am I Not Losing Weight?)

How do I know this? How can I be so sure?

Because if you WERE doing everything right and you WERE in a deficit, you’d currently be losing weight and we wouldn’t be having this conversation.

    Hello and thanks so much for this honest and frank article!

    I know you have heard it a thousand times but I really have tried just about everything under the sun and struggle to lose even a measley 5-10lbs. I am a 42 yr old man, weighing 210lbs at 5’8″ and have been battling the buldge since my late 30’s. I have tried everything from atkins, the raw food diet, shakes, diet pills, prescribed diet pills, have had my doc test my thyroid repeatedly (only to have the test results always return normal),Its freaking depressing when you go to the doctor hoping that they find something wrong with you, lol. low carb, cortisol blockers and more all with intense weight lifting for off and on for the past 3 years with again…little to no weight loss. And the moment I stop working out for even a week – I gain those little bitty 3- 5 lbs back after 2 or 3 meals. No bullshitting! I there were a TV show for the for the person who could gain the most weight the fastest called ” The Biggest Gainer” I would win no doubt!!!

    But after reading your article I can honestly say- calorie counting or creating a caloric deficit I have not ever focused on. I shall try as it makes sense to me. However, I accustomed to eating pretty good low calorie food already (to a degree), what is a good number per day to shoot for, for a man my size?

    Thanks for any info!

    • says

      loled at “Its freaking depressing when you go to the doctor hoping that they find something wrong with you.” I bet a lot of people know that feeling.

      But I promise, focusing on your calorie intake and creating a moderate deficit is the solution you’ve been looking for.

      As for how many calories to eat, start with this.

  2. Maria says

    Thank you!!! So far, I have read a variety of your articles and found them to be informative and valuable. I can relate to this article – I am now 35 years old and very overweight, but as a teenager dealt with an eating disorder in multiple attempts to lose weight. For a decade, I avoided the topic of diets and workouts like the plague to keep from turning back to those habits, but in the last five years have been developing an understanding of my body. For a long time, I thought that “starvation mode” was the reason I could not lose weight and kept packing on the pounds, however understanding BMR is helping me to recognize that it is not “starvation mode” but the unhealthy habits I have kept for decades. Like skipping meals until, say…3pm then snacking continually, or doing great at an exercise and weight loss routine but ending in too high of a deficit one day. For whatever reason, it triggers massive difficulties with binging, and exercising over the next few days. I love your articles because they advocate reasonable methods, and setting goals in a way that will get results, but which shows enough self-care that you do not end up in a war with your body…in 20 years, it is a war I have yet to win, and I am frankly tired of fighting. I would much rather team up with my body, than be hatin’ on it :)

    • says

      Glad to hear it Maria! I’ve heard from quite a few people (almost always women) with a very similar background story. “Teaming up” with your body rather than “fighting it” is a damn fine way of putting things.

      Keep me updated!

  3. Shae says

    So I learned quite a bit from this article and i appreciate it. I am curious though… I have a slightly underactive thyroid, but take iodine for it.
    Um, i exercise a lot. Competitive figure skater, gym, running, biking, swimming (basically anything cardio/endurance based), and my nutritionist and doctor tell me i need to eat more. I dont eat red meat, and i am lucky to eat more than 1,200 a day (usually about 900). I keep a food journal, so i dont get “free” points like in your example, but I CANTt FREAKIN BURN FAT. I have a shyte ton of muscle and i build muscle but the fat wont go away it just kinda stays on top even as muscles are noticeably developing. and my coach says i need to lose weight too, and now i have blood sugar issues (if i dont eat often enough I pass out). I am not diabetic or hypoglycemic (I’ve been tested).

    I do eat a lot of chicken, eggs and fish, rice and fruit. Decent veggies. I crave sugar. The only time i seem to drop a pound here or there sporadically is if i cut all fruit and any form of sugar out of my diet. But then my blood sugar seems more apt to drop (this happened in competition recently… If was awful). It was as if i had no back up stores of blood sugar and my adrenaline seemed to fail as well. And my coach was pissed because i’d not had any carbs/sugars for sugar storing for my long program performance. I’m desperate here.
    I don’t know what to do. It cant be “starvation mode” obviously. But what IS it? Do you have any tips?

      Sorry, but whenever health issues/medications enter the conversation, I automatically avoid giving any kind of specific advice. This is the kind of stuff to ask your doctor.

      However I can tell you that it will always come down to calories. So if you found you lost weight only when you stopped eating fruit/sugar, I can promise you it was not the fruit/sugar… it was the calories it provided.

    Could you perhaps move the part about not recommending drastically lowering your daily intake somewhere to the beginning of the article?

    To be honest I have never even heard of this myth and even without my education in the field of biology I would probably find it ridiculous just due to the real world examples you presented, but I have severe lack of confidence in people who read stuff like this – I would bet my life that there must have been a lot of people who entered the website while already being on extreme low cal diet just after some random argument with people claiming something in the lines of this myth(or in the worse case even proper scientific explanation of this problem which the listener only wrongly identified as claiming that this myth is true).

    I strongly believe there were many who just briefly went through a few lines just so they could say “Hah, I knew I was right all along” and never even glimpsed at the part where you explain why they should not starve themselves and so they continued in that just to suffer from muscle loss, deprivation and possibly much worse medical problems.

    (English is not my first language so please pardon the mistakes if there were any.)

      You may be right, but in that case I think it’s pretty safe to say that I could put that message in every other paragraph and it’s probably not going to matter. Just like how you could put warnings all over a pack of cigarettes and people are still going to smoke… people with eating disorders aren’t going to be phased by a recommendation that eating that way is a really bad idea. They need professional help.

    Hi !
    I agree with you article completely, but I am a little stuck and need some advice. I have been tracking my macros religiously for the last 8 weeks, weighing myself every morning (so that I have a weekly average) and not losing a single pound (same BF%: 23%) so I assume this is a real plateau. I do weigh training (similar to what you recommend, I’ve read your workout programs) twice a week and I do crossfit 4 times a week (because I enjoy it). I have lost 22 lbs and went from 35% to 23% body fat in 10 months with some muscle gains since I was a complete beginner (pretty cool!) I was just doing the weight training (one full body and one upper body/ one lower body and some form of cardio or sprints twice a week). I started crossfit because a friend insisted and I really enjoy it so I decided to make it my cardio and it certainly burns much more calories than the cardio I was doing before, so I don’t understand the plateau. I am 5’4, 130 lbs now. I don’t have a goal weight, I just go by the mirror and i clearly want to lower my BF% and I don’t lose anymore fat. I eat 1300-1400 kcal/week, 110-130 grams of protein and the rest is fat and carbs depending on what I want (I am sure about the numbers and tracking my macros is how I lost weight for the past year). I was thinking of eating at maintenance (I am not losing anyways, so I might as well eat in order to support my training and… have more energy). Do you think I should just eat 500 more calories a day (would I gain fat if I just do that since I am kinda maintaining at 1300 with crappy mood and recovery)? Or add them progressively… I do feel fatigued, I don’t sleep as well (8 hours per night but I wake up several times in the middle of the night) as I used to and I am not losing fat so maybe eating more can help, and I can lower my calories after a few weeks or months (I am not in a hurry) to lose more fat… Any suggestions?

    • says

      If it has been 8 weeks of no weight loss whatsoever (and there are no health issues at play), then you are simply not in a deficit.

      Also, you’re not “thinking” of eating at maintenance… you’ve apparently been at maintenance for the last 8 weeks.

      If you are fatigued/moody/not sleeping well, it’s most likely to be due to the 6 total training days you’re doing per week (4 of which are crossfit, which are known to be stupidly high in intensity/volume/overall pointless insanity).

      And if you’ve been losing fat for about a year straight now with no diet break, chances are you are certainly due for one. I’d suggest deloading from training for a week or so, and taking a 1-2 week diet break as well.

      • Kate says

        Thanks a lot for the reply!
        That means that my maintenance is around 1300/1400 including all my training…
        Damn (I eat the same basic food so that makes it quite easy to track it…). About health issues, I did not have my periods in 7 months (I think my lifestyle change has something to do with that) and I moved three times (3 continents) in the past year… I went to the doctor and did hormonal tests… everything is ok (well something is obviously wrong since I have an Amenorrhea, but they just said “oh you must be stressed that’s why”). Since everyone is always assuming that they are in starvation mode/ are different/ have bad genetics and a particularly slow metabolic rate, I try to avoid that kind of excuses… But I do suspect some kind of hormonal changes that could impact my weight (at least some major shifts in water weight)…
        Anyways I am going for holidays in two weeks so I’ll just take advantage of that, get some rest and deload and hopefully that will help… I did take a full month of diet break (without training) because I was moving away and had other things to take care of (I was not tracking but I would say that I was eating at least 1800 Kcal/day) and I actually lost 2-3 lbs (probably some muscle), that’s why I am surprised that I am maintaining at 1300…

  6. Sara says

    Thank you so much for this article! I’m tired of hearing this myth from my friends and other people, I know exactly how much I am eating thank you. I believed in this at first and gained weight but now I am finally down 4 pounds after a few weeks! Will be sharing this and referring to it in the future.

  7. Bob says

    Does 1 refeed day per week really boost up your metabolism from your metabolism slowing down from prolonged periods of dieting? I’m not sure if this is true or not but people are saying refeed days bring leptin and your thyroid hormone up to speed up your metabolism. And if so is an 1000 Calorie surplus to large for a refeed day?

  8. Scott says

    Hi there, great article!

    I was just wondering, how do you know if you’re body’s metabolism slows down (as a result of a large deficit)? Also, if this is the case, does that mean there is a chance you could be in a caloric surplus without realising due to the fact that you have no idea what your new caloric maintenance level is?

    • says

      There’s no sure way to know beyond the rate of weight loss occurring slower than would be expected based on the size of the deficit created.

      As for the second part of that question, no. This article was written to prove this very concept is bullshit.

  9. Chris says

    I’d be curious as to your explanation of the following…

    While I was last dieting successfully, I would get ‘stuck’ from time to time. I would hit a plateau and lose nothing for a while. I found that having a ‘cheat’ day and eating higher calorie would kind of ‘kick start’ things for me again, so long as I went back to my lower calorie eating afterwards. I always assumed this was the whole ‘starvation mode’ thing and when I showed my body I wasn’t going to starve it, it finally would let go of that weight. But according to you, this could not be true. So, how does one explain my experience?

      • Chris says

        I would say I didn’t see a loss for a few weeks prior. Then I’d eat more one day and drop a couple pounds that week. In the end, everything averaged out to about a pound a week loss but I’d go a few weeks with nothing and then lose 3lbs the next. And it seemed to always coincide with a ‘cheat day’ so I assumed I was ‘shocking’ my body back into losing again. I am open to the possibility of other explanations. I’m just curious :)

  10. Drew says

    I have a question that I haven’t found the answer to anywhere, so if you’ve already written about it and I missed it – I apologize. I have figured out my macros and caloric defecit, but I FEEL SO FULL. Is that normal when you actually begin consuming the correct macros. For example, more than likely my diet has had WAY TOO MUCH carbs and bad fat, and not quite enough protein.

    Summary: Is it normal to feel a lot fuller than I did before I started eating at my calorie defecit, now that I have my macros adjusted?

    • says

      Definitely. Higher protein, more fiber, sufficient fat, more vegetables, less junk, etc. = all things that keep people fuller and more satisfied on their diet (which is a big part of why all of this stuff is recommended in the first place.

      So if some or all of those things were lacking in your diet before, there’s a damn good chance you’d feel fuller now even with overall calories slightly lower.

  11. Lucas says

    Thanks for this post. You are the only non biased, no bullshit website i know and everything ive read on this site worked. I read the article about reps and sets and i used to increase the weight after each set because that’s how i was taught in h.s. football but now i do the same weight but decrease the reps like an upside down pyramid and ive had crazy results and ive made huge gains in strength. This article is good because im about to go on a 21 day water fast (28% BF) and everyone tells me ill go in “starvation mode” and im “starving” myself but in a way im not because my body has enough fat stored up and itll use that before breaking down my muscles and being catabolic. Whats your views on fasting to lose body fat?

  12. A says

    Question. So, I’ve heard the myth of starvation mode. I had a roommate tell me she had experienced it herself in high school (I’m also pretty sure I had heard about before she told me about it. . .) Anyway, the way she explained it, it wasn’t that her metabolism slowed down so much as you said, but that her body was holding onto the calories she was putting in, since her body didn’t know when she’d be eating again. Can you explain this?

    • says

      It’s complete nonsense.

      And it’s the same thing being discussed in this article. That something happens where you eat too little and your body completely prevents you from losing weight (or “holds on to calories” or however you want to describe it). It’s the same thing. And it’s a myth.

  13. Kim says

    Hi, i was told once that if you create a deficit amount of calories you eat a day and stick to a deficit plan for long periods of time your body will gradually change so it could use less calories during a days daily function because of the little calories it is receiving, sounds pretty ridiculous, but is this true?

  14. MaryAnn Carilino says

    How do you track your calories consumed? do you recommend following up on an app and weighing your food?

  15. Chris says

    Great article. Wonder what your thoughts are on reverse dieting? It was created as a way for fitness competitors to increase calories slowly over time after intense weight loss and calorie restriction before an event. Increasing calories by a small amount (50 or so calories per day per week).

    Seems to be a nice way for athletes who do a ton of training and sometimes do long periods of calorie restriction to get back to maintenance level TDEE again without huge weight gains.To me this makes logical sense to not increase calories after long weight loss by a dramatic amount and slowly ease into eating more again.

    Reading some success stories it appears to work great for a lot of very active people previously restricting calories too much (not something an obese person would need to use).

    • says

      I think it’s a good thing. Although the average person at an averagely lean body fat percentage won’t need to be nearly THAT precise or gradual when doing it. But generally speaking, yes, it’s a good thing.

      A girl by the name of Sohee Lee just wrote a book about this topic. I haven’t had a chance to read it yet, but I’ve heard good things.

  16. Ally says

    I love the tone of this article. Informative, funny and edgy. I always suspected the whole “starvation mode” thing was a myth, for the very same reason. I had a friend tell me that I would go into starvation mode if I didn’t eat enough and I said, “well wouldn’t anorexics be fat?” And he said, “no, they have an eating disorder.”


    LOVE the article!

  17. Hanna says

    So does your body go out of “starvation response” once you start eating? I don’t see information on what happens when you have lost the fat and resume a maintenance calorie level. Does the body’s metabolic rate now boost back up? And I also wonder how long is too long before the starvation response kicks in at any level… is it a week of intense deficit, or a month? Or 3 months of moderate deficit? I wish I could find studies on this. Thanks for the article.

    • says

      Any metabolic/hormonal issues that happen as a result of a prolonged deficit return to normal when the person comes out of the deficit. This is why refeeds, diet breaks and reverse dieting are all things.

      And no, there is no specific time frame. It will vary based on factors specific to the person, the amount of fat they have to lose, the severity of the deficit, etc. etc. etc.

  18. elkie says

    I love this article and the way you write ! you had me in stitches lol !
    I hate to admit once upon a time I jumped on this “starvation mode” bandwagon. Glad to say I have wised up since then! Loving your blog, working my way through your articles, what I have read so far has all been top notch !!

  19. Letitia says

    Hi, what would be considered excessive cardio exercise? I walk a 10km track on most days, it does have a gradual incline and decline and gets my heart rate up. It usually takes me 2 – 2.5 hours to complete. I’m very overweight. I feel great after, mentally, my feet are a little sore at rest. Would this be considered excessive?

  20. Viel says

    I’m so happy I got to read this. It feels great to finally read something that won’t sugarcoat the truth. Love this. I’m sending the link to all my workout buddies

  21. Grace says

    Thank you for this post!
    So starvation mode is a myth, what about metabolic damage? Is that a myth also?

  22. Alex S says

    Thank you for this post!
    I don’t see how the starvation mode thing can be real.
    E.G. I’m a 19 year old female who weighed 121 pounds when I got struck with appendicitis ( i know this is accurate as they weighed me at hospital to confirm). I had a bad reaction to the surgery, got septicaemia and could not keep any food down what so ever for 5 days, just threw it immediately back up. I also never left my hospital room. On the last 2 days I managed to keep about 400 cal a day down and do very short, slow walks.. Overall I was in hospital a week total and came out weighing 115 pounds (6 pound less!) from a weeks starvation. In my experince this confirms ‘Starvation mode’ is DEFO BS.

  23. Aaron says

    Thank you for educating me on the subject of starvation mode. It was a very detailed read with excellent information. I was once one of those people that came to believe the misinformation that starving oneself would stop weight loss, but now everything makes complete sense. Thanks for this post.

    By the way, do you have a YouTube channel by any chance? This site has so much great information that should be put into video.

  24. Miecey93 says

    Thank you so much for your honesty. It was much needed. I have a question, I am supposed consume 1410 calories per day. I ate 1198 and burned 635. My net calorie is 563. Does that mean I will lose weight this way?

  25. Fabiola Byrne says

    The article was a real wake up call. I am trying to lose about 55 pounds and I am great for 2/3 weeks and then can’t understand what’s going wrong. Of course I stop being as careful counting the calories. Is 1lb week ok?

    • says

      Glad to hear it! As for 1lb per week, it depends on how much fat you have to lose. For the average person with an average amount of fat left to lose, it’s fine.

  26. Manny says

    Thank you for the article. It was super entertaining and informative. I am a big fan of the beachbody workouts (insanity, asylum, T25, and now max 30) but have struggled to get the results that I’ve wanted. I had amazing results with the original insanity but I’m not sure if it was due to “noob gains” as I have never really moderated my caloric intake. I’m 5’7″ and at the end of insanity I was down to 127lb granted I had a big head and stick arms and legs.

    Now I’m at 145lb approx 2 years since I first finished insanity, and now I’m starting to look deeper as to why I’ve slowed down. I knew the answer before even reading your article but damn you did such a great job of just preaching it. Nice job.

    -btw I love your site. Its super clean and easy to navigate.
