Starvation Mode – Why You Probably Never Need to Worry About It

Starvation mode is a term that gets thrown around loosely. Many people believe that too little protein or too few of calories in a day will cause loss of muscle mass. What if I told you that it is extremely difficult to go into starvation mode until you get down to 5% body fat(10% for women)? Brad Pilon and John Barban have given me permission to give you access to the first 15 minutes of one of their paid recordings: "Starvation Mode". Brad and John discuss surprising findings of a military study, where they purposely tried to get the soldiers to lose muscle and get into starvation mode. They found it took extreme conditions to reach this point.

[Just a cool vintage restaurant sign. This reminds me of something you would see on a road trip in Nevada or Arizona on a 2 lane highway, hours from the big cities.]

Brad and John Show You How to Get Into Starvation Mode?

These guys take an interesting approach. They show you exactly what it takes to reach starvation mode. By showing how difficult it is to reach starvation mode, they destroy a lot of muscle loss myths. Once you listen to this, you can relax and not stress out about losing muscle when you are dieting and exercising to lose body fat. As you will see, you don't even need to begin to worry about this until your reach crazy low body fat levels. Here's that recording:


How to Get Into Starvation Mode

[Click on this old school cassette tape. Using sophisticated computer technology, my blog will play this bootleg in fancy MP3 format.]

My Notes From the Starvation Mode Recording

All of this is covered in the recording, but I wanted to put some of this in text as well. You can also right click and save this recording and listen on your computer or iPod. I'll post my notes below like I typically format my blog posts.

Why Are Brad and John Examining a Military Study?

Brad and John mainly look at a military experiment done by Karl Friedl. They point out that the military has less restrictions and can push people much harder than they can in a typical university study. There is no way this stuff would get approved by a university, but no problem for the military. In their words…To find limits to what the body is capable of, you need to dip into military research.

Step 1 to Get Into Starvation Mode—> Start Out Lean

Karl Friedl used fit and athletic soldiers with an average body fat of 14%. This is what John Barban calls "4 pack lean". There were guys as low as 6% body fat and as high as 18% body fat. Think along the lines of a fit and muscular soldier to get an idea of the participants of this study.

Karl Pretty Much Tortured These Guys for 8+ Weeks!

Karl had these guys eat between 1,000-1,200 calories…but burn upwards of 6,000 calories per day with crazy activity levels and sleep deprivation. So deficits in the 3,000-4,000 range on some days. Average deficit was 1,200 calories per day. They trained like mad and also went through extreme sleep deprivation.

Here's what happened during the 8 weeks (avg height 5'9"):

  • At Start… 167 lbs & Adonis Index of 1.4
  • 2 Weeks…156 lbs & Adonis Index of 1.44
  • 4 Weeks…152 lbs & Adonis Index of 1.45
  • 6 Weeks…146 lbs & Adonis Index of 1.50
  • 8 Weeks…140 lbs & Adonis Index of 1.52

Note: Adonis Index refers to the shoulder circumference divided by the waist circumference. As an example, my shoulder measurement is 50 inches and my waist is 33 inches. If I divide my shoulder by my waist I get 1.51. The ideal Adonis Index is 1.61. The video below explains why a 1.61 ratio is pleasing to the eye in not just body proportions…but in art, architecture, etc.


[It is interesting to note that so many things follow the Golden Mean or Golden Ratio. This video claims that even many cereal boxes are made with these proportions to be more pleasing to the eye...so the cereal companies can sell more cereal.]

In This Experiment, They Were NOT Trying to Preserve Muscle

The important thing to remember in this study was that they were trying their best to beat these guys down. They weren't doing things that normal people would do while dieting, like proper resistance training. Here are some of the tactics they used to try to get into starvation mode.

  • Severe Caloric Restriction
  • Severe Amount of Exercise
  • Severe Amount of Mental Stress
  • Extreme Sleep Deprivation

Began to Lose Lean Body Mass Between Weeks 6 and 8

At around the 8 week mark a lot of guys who were in the 5%-6% range could not drop any more body fat. This is when they began to lose lean muscle. The guys who started out the leanest, reached their limits at week 6. These were the guys who lost the most amount of lean body mass.

They Didn't Lose Muscle Just Because They Were at 5%-6%

They lost muscle because they were still having days where they were running at a 3,000 calorie deficit. Once someone reaches their lower limits of body fat percentage it makes sense to eat close to maintenance levels. This strong calorie deficit at this low body fat level also caused extreme hormone disruptions: Testosterone dropped, thyroid issues, mood changes <---this is true "starvation mode".

Why People Think Their Metabolism is Slowing Down

People with more fat available to oxidize…can oxidize more body fat per minute. The less body fat you have, the less you can oxidize per minute. So as you get closer to your lower limits of body fat, the slower you will burn what body fat you have. This is why those last 4-5 pounds come off slowly, NOT because you are wrecking your metabolism with an aggressive diet.

Most People Never Need to Worry About Starvation Mode

Most likely, starvation mode isn't happening to anybody reading this. The average person thinks starvation mode happens between meals. It isn't about not having enough calories. It isn't about not having enough protein. It only effects people at their critical low body fat mass. You have to be in a massive deficit and already at your critical low body fat level. You are "6 pack ripped" before ever getting to starvation mode.

Summary: John Barban and Brad Pilon have tons of posts and phenomenal recordings over on these two blogs they run…

Adonis Index Blog <---For Men
Venus Index Blog <---For Women

All of their posts challenge bad info and myths with good solid scientific research. I've been following these guys for 3+ years and have learned a ton from Brad and John, especially when it comes to dieting for rapid fat loss. Great stuff!

This is really awesome information! I'm so happy Brad and John let you share it with us.

I must admit there were a lot of times that I thought I was in starvation mode, especially during my Visual Impact Phase 1 challenge. This study has definitely given me some piece of mind.

The one factor I'm struggling to wrap my head around is the extreme sleep deprivation. This is the one I 'believed' has held me back from optimal

(sorry .. Continued)
…held me back from optimal results. But after reading this I'm starting to realize that maybe I was wrong.

Rusty, were there any detailed notes on sleep deprivation? What effect did it have on soldiers in terms of muscle loss, if any?

Thanks for the awesome post!

Lloyd said:

Hey

Awesome post! Makes sense.
However, I'm in a tough place right now. I'm 19, 6 ft 1 and about 179lbs now. I realise that to get a good physique, I still need to gain more muscle, as I have only been weight training for 1 year. However, I need to cut fat also, as i have some body fat which is hiding the abs and some stored especially around the lower back.

What is the best way to go about this?

Cheers

Excellent post Rusty.

I have participated in 7 fitness contest reaching insane low levels of body fat, and not once have I lost lean mass despite that I in some instances have been pretty aggressive with the calorie deficit.

If you approach your strength training the right way you will give your muscle an even stronger signal that they have no other option than to stay.

Excellent analysis I'll definitely agree on this ( yeah I don't always agree). I have lowish body fat (how low? don't know) but I find that when I fast or accidentally go without meals (like flying on a plane) there is no noticeable effect on the body except just helps me remain lean but when I add in extra extensive cardio sessions that's when I do start to shrink a little! So starvation mode for me anyway is not an issue
Ha the old cassette tape ..very cool!

Ahmed said:

So, does that mean that protein intake does not affect muscle loss? So when one is cutting, protein intake is actually irrelevant?

It just shows what the body can endure. And all this time I thought two intermittent style fasts per week was a lot. Just another validation that you need to eat a lot less than you think to get lean.
Love the cassette tape by the way!

I really love reading your blog. The information that I find here is not written in fitness study guides. This post helped me understand so many things, because I was always paranoid as hell when I didn't eat every 3 hours all I could think of was me loosing my hard earned muscles, because when I studied that's pretty much what the books teach you ( if you don't eat every 3 hours you loose muscle mass ). The stuff you are teaching here is outside the box, just like Tim Farris book ( that I also found through your site and I love it very much ). Thank you for this great site.

Rusty,

It sounds like these soldiers had it pretty hard for those couple months. For the average person, starvation mode is probably something one would not have to worry about. You can keep your muscles while getting down to that 5-6% body fat range, but as the study found, if a severe caloric deficit is continued, the risk of withering the lean body muscle is greatly increased.

Good points all the way around, Rusty, and thanks for sharing.

Okay! But they were training like mad, I don't care if they didn't have access to the weight room. What would be the muscle loss if they were only sitting in front of the PC and walking to the shop? I really look forward to the answer

Interesting recording. Starvation mode is always something you hear about.

When people throw these terms around what they don't realize is that most people today are very overweight. The game changes when you have lots of body fat. Starvation mode is to protect us. If you have extra weight on you then there is no need to go into starvation mode because your body has lots of extra fuel. Enough to last a lot more than a few meals or even a couple of days.

Jun said:

This is really useful info, and good to know next time I get paranoid that I'll become too skinny or lose muscle. From what I understand, it is near impossible to lose too much muscle if proper exercise is involved. I do have two questions though: 1) What type of exercises were these soldiers doing? Were they resistance training or mainly running around? 2) What was the macronutrient breakdown of their calories?

Awesome post, Rusty…I spent years paranoid that if I didn't eat every 3 hours on the dot, I'd lose that hard-earned muscle. Can't believe I bought into all that marketing hype!

John said:

This is great info. I would say it gives us more than just a reality check about starvation mode or protien guilt. Those are just the important ones for Brad and John to highlight.

I think there is at least one other misplaced guilt that this study sheds light on – 'resistance training guilt'. It seems to me that the idea that we need to treat our resistance training regime as the 'insurance policy' to accompany a weekly calorie deficit is really only a major issue when reaching body fat levels of well below 10% – more like 6%. That's how I read these results.

That's quite important and a bit of a shake-up in thinking. It means for example that while dropping body fat we can use our weights sessions to work on those areas of our physique that we think will give the greatest pay-off, rather than weight training to stave off the Catabolism Monster!

In my case (and I've just reached an AI of 1.4 from a 1.25 starting point in June), I can have no guilt about focusing more on specialization exercises rather than the 'big four' compound lifts, if that's what is more amenable to tweaking what nature has given me.

I can even emphasise fat-burning exercise ahead of muscle-building, and it won't be a big deal until my fat stores get to crazy low levels.

On the other hand, if my weight training was my 'essential insurance policy' while trying to close in on a sub 10% bodyfat goal, I'll probably be antsy about being on a full mass-building program for every muscle group the whole time.

seth said:

When I start dieting and cutting down pretty hard, why do I start losing strength then? My doctor thought I was at about 7% body fat, from just looking at me, but I think I could go lower. I would do my same workout and every week I would lose a rep or so off of what I was doing the week before. What gives?

mark Winward said:

Brilliant research. It also makes dieting a little easier to stick to once you relaise that, if honest with yourself, you're body's not going to go into "starvation" mode while you sleep if you skip that midnight Casein Protein shake!
The only benefit I can see to eating regular meals is that it's easier to stick to good foods at the next meal. I'd like to know what happened to these guy's body fat levels after they went back to a normal routine,.i.e. resting Blood glucose levels, BF, Blood Pressure and lean mass. It's concievable their muscle mass went up?

Great post Rusty – As a keen fan of Eat Stop Eat and IF, I do give my body a break from food every month or so and always feel better for it. I do not really concern myself over the science of it all because it is not a major part of my life. No need to get too hooked up about starvation beacuse as you say so many of us aren't even in this category. People sometimes argue that fasting will damage your body but they haven't done the same kind of reasearch that Brad et al have done…our bodies are sensitive machines and will surely let us know if something needs to change. Keep it simple and varied – that's my approach.

Hey Rusty,

Thanks for this article man! ;-)
This will take a HUGE weight off off many folks' mental shoulders.

I think another reason for a lot of confusion is that most all this muscle-loss info/myth comes from the fitness industry.

Commercial interests aside, the main thing really is that a 240 pound lean bodybuilder will lose muscle mass much more readily than someone with a natural, good level of lean mass.

Simply because the body doesn't need nor want this excess weight (goes for both excess fat as well as excess muscle). So that excess drops fast and easy. I mean, heck: they stop using gear and they lose mass right away, never mind calorie deficits etc.

Just like a clinically obese person drops weight super fast initially. Same difference.

But a good lean, functional physique will stick with you all the way, as you once again pointed out: this is honestly reassuring man!

I'm going to extreme leanness levels now and this is really good to know that there's absolutely nothing to worry about as long as I keep up some weights and stay close to maintenance once there.

Thanks Rusty, you rock as always! ;-)

Mark

Highly interesting Audio btw!

Rusty, you have done much to change my ideas about lean muscle growth… actually, most of what you and Pilon /Barban talk about is very similar to what I naturally did back when I was a lean 190 lbs.

As an experiment I ballooned up to 250 and became a pro strongman, but now that I'm working my way back I have had to re-brainwash myself back towards the direction where guys like you stand.

So, thanks ;)

Pamela said:

Great article! These mainstream fear tactics against not eating every 2 hours are lookin' pretty stupid. I love your website!! I've read almost all the articles and thank God, you actually make sense & have some logic. Most of the mainstream stuff make no sense at all but for those who aren't very educated about the science behind the human body can be kind of frightening even if they do seem to go against logic.
Thank you so much for being no-nonsense, I really appreciate all the work you've done! Your clarifications have made my life much, much simpler (because now everything is coming together)!

Josh said:

So 14% bodyfat means a four pack with flexing? Thats an interesting comparison. Great Article

Michael h said:

hey Rusty,

Great post! Thanks for sharing!
I think I'm gonna fast for the next week now! ;)

I just noticed that you have 10,000 people that like your Facebook page. That's impressive! With that many fans, you should be making videos and posting them to YouTube and then sharing each video on Facebook. Heck, you could eventually start making money on YouTube by posting videos, especially with the fan base that you already have.

Thnks again,
Michael

Michael h said:

One more thing,
What if I were to fast for the next two days? I'm at 10-15 percent body fat right now…
No risk of muscle loss, right? I can't stand hearing from different sites: "you gotta make sure you're eating as much as you can when weightlifting or else you risk losing muscle" or "how do you know you're not losing muscle instead of fat when fasting?"
I hear similar things like that from professionals, though as far as weightlifting goes (seriously though, they know what they're talking about when it comes to lifting more, but I'm not sure about their knowledge on diet as far as muscle loss goes).

It seems we are posting on the same topic this week mate :)

Great to see there's even more information out there than I'd first thought to help put this whole 'starvation mode' fiasco to rest.
The human body is too clever to allow itself to lose muscle when it needs it for survival.

exwannabe said:

Loyd, about your comment:

"However, I need to cut fat also, as i have some body fat which is hiding the abs and some stored especially around the lower back."

This is an area the Lyle Mcdonald has addressed in his "stubborn fat protocol". Do a web search search on it.

Rusty: Thanks for this post. I am one who might well have been overly afraid of this issue.

Sue said:

When you get to a very low body fat is that your body wants to hold on to the last bit of fat or that what fat there is can't be oxidised fast enough? I wonder if the above level of body fat is individual ie the point at which your body holds on to the fat can be higher in some?

Leo said:

Hi,
Great info! Just thought I'd mention something about the claimed ideal ratio of 1.61, as backed up by the video. While it may be correct that people do find a ratio of 1.61 to be quite pleasing, because our ratio is measured in shoulder and waist CIRCUMFERENCES, the resulting ratio of the visible shoulder width to waist width is not necessarily the same. For example, my waist circumference is 31", and shoulder 46", giving a ration of 1.48. BUT, the visible width of my waist (meaning what people see from the front) is only 14", and the visible width of my shoulders 18", giving a ratio of only 1.28 – a big difference. So, for people to have a visible shoulder to waist ratio of 1.61, the difference between their shoulders and waists would have to be quite large – almost unachievably so, I think.

Adam said:

Although a lot of us already know this…but mainstream fitness still doesn't have a clue. This was a great supplement to Brad Pilon's and John Barban's work. Rusty, thanks for more info!

Adam

BestFatLoss said:

Very interesting article. Note to self, check out military studies on weight gain/starvation in the future.
But I do agree with Leo's comment.
The 1.61 ratio seems sort of skewed to me.
I'm going to put together photos for comparison to figure out if this truly is most appealing.
a ratio of 52 inches/shoulders, 32 inch waist seems a bit extreme for a height of 6 feet. I'm a girl and don't know if I find guys most attractive at that shape.

D said:

Another fat loss myth busted!

If a guy wants to go from 20% body fat to single digit with diet and IF, should they switch phases in VI and start with phase II to spike GH and weight loss then go back to phase I when they can eat more to support the growth stage?

Rusty,

I hope this article gains plenty of traction because this is one of the most misunderstood notions in health and fitness. Once I started fasting and restricting calories, I lost no muscle, only fat. I also feel more energetic and less sluggish throughout the day.

André — PostPeakLiving.com said:

I love hearing this…but it would also be good to know if there was evidence for the reverse. Are people just repeating what they've heard and there's no evidence whatsoever? Often there is *some* reason for why people say muscle gets lost.

Does anyone know?

September 15, 2011

John said:

André,

In one of Brad Pilon's other audios associated with Eat Stop Eat, he noted some studies showing excessively overweight people did lose some lean mass when placed on a really restrictive daily caloric intake.

But the researchers in one of the studies made the rather important observation that a fair bit of that observed lean mass decline has to relate to the shrinking of the gastro-intestinal tract, as the person goes from obese to a more normal body weight. That counts as a loss in lean mass even though we don't tend to think of that when we talk about 'muscle'.

Chris said:

This is pretty interesting, especially since when people are worried about starvation mode, especially in others as they try to diet. It is just another worry that is exploited by the food industry.

I have gone on very little and seen great results and most of the time I am pretty sure I was able to increase lean body mass a bit as well…

I've been following Brad for a while and also Martin of lean gains and much of what they talk about is based on science…which is why I like their stuff. I am finding it harder and harder to deal with these magazines which tell people to eat every three hours and take massive amounts of supplements to avoid starvation mode. I really wish more people would look into the science of things instead of believing what they see and hear from so called experts!

Keith said:

Awesome article Rusty. I hope everyone reads this article. The one thing I hate the most is when people say "OMG I'm starving, I haven't eaten in 4 hours." That really makes me go crazy sometimes haha.

Great post as usual Rusty, your site really offered me a new insight into eating, I used to overeat reacting to the signals that I was hungry, not realising that was just a trigger for what time I was used to eating, I used to go from great shape to poor shape often, now I am in good shape again and hope to maintain this for the rest of my life.

Meade said:

THIS IS FALSE!
Starvation mode is very real! Why do you think people can survive for months even without food (not without water) and not starve to death? Because they arent eating, their body starts eating itself (muscle) for preservation.

Starvation mode is very real. I cut my calories below 1600 and I lost a lot of muscle so it was harder for me to lose the weight I regained once I started "eating normal" again. This is hard. Starvation mode is very real. Its actually a gift we were given so we could go for long periods of times without food and not die.

September 19, 2011

John said:

Meade, the key point is which out of the body's various energy stores are mobilzed first when put in that state of a calorie deficit?

Someone proposing that muscle is the first thing which gets broken down needs to provide studies showing this, because research like the study being discussed is indicating in all but the super-lean, it is body fat that drops in preference to muscle.

There's also a complicating factor that muscles can lose a bit of their volume when we keep them deprived of glycogen through persistent hard dieting or eleminating carbohydrates.

Wes said:

@Meade – the point is that it is real, but not something the normal, everyday person is going to ever experience from not eating breakfast, skipping a meal, or fasting like the mainstream fitness dogma presents.

As for the AI Ratio, having been a member of AI since early last year, reachign 1.61 is possible, yet it can be difficult if one has much muscle to gain. I've watched I dont know how many guys come thru the program and hit 1.6 and talk about how their lives have changed after hitting 1.5. I hit 1.7 at one point last year. It is very much possible and if you don't believe it, go check out the contest winners on their blog.

September 22, 2011

phil said:

@meade: i think the research makes fairly clear (and sense, i believe) that you need to be at the extreme end of body fat levels and be in a continous state of significant and constant caloric deficit for starvation mode to occur, ie for the body to start drawing energy from muscle tissue and, at the very final stage, from the organs, to survive. however, in your defence, some muscle loss is inevitable, because the one question the research doesn't consider is how much muscle the body actually needs at the stage they were at with their research? if you're at 225lbs with 5% body fat, then as sure as night follows day you will lose some muscle mass, as there simply is no call for that much mass to be lugged around ….. and i guess it gives rise to the bigger question: how much muscle do we really need? i dunno, would be keen to hear other opinions on this matter.
great post & provides lots to think about, that's what matters.

bestfatloss said:

I really like Brad and Martin's science based approach. They are more on target than the vast majority of so called science writers in major newspapers (NYTimes' Jane Brody is quite egregious in her babble. Her latest story is absurd and would leave the average reader to believe one can't lose weight without taking a year to lose 20 pounds ! )

sixpackhabits said:

Good info to keep handy, I set some fat loss goals about a month ago and actually convinced myself I wasn't eating enough and was losing muscle when I was probably at most running with a 1k calorie deficit. I'm looking to get a six pack for the first time in nearly 20 years but I have been pre-occupied with the notion that I might lose muscle while cutting.

September 24, 2011

Jason G said:

I think muscle loss can occur when eating 1600 like maeda said.

However many factors come into play. I believe the body can tell what the useless body mass is. If you are built like a bodybuilder and you stop working out when cutting calories, your body will say "oh this is not needed". On the other hand if you are obese your body will eat through the massive amounts of fat. Like this article indicates if your 5% fat and in the military you probably have more lean tissue, so your body will probably consume muscle in a calorie deficit.

Moreover protein is necessary so if your not getting any… then your body will break down your muscle to some level. How much do you need? I don't know. But if protein is consumed when in a massive deficit, it should probably be consumed before a state of rest when the body is not going to use it for energy.

What is important about this article and Rusty's site is that he points out that we really should be lean. But we think we need to eat so much or we will be unhealthy. How many fat people do we know who need to eat five times a day so that they can get lean? The reality is most people should be eating 2000 calories or less a day in this world to maintain a real healthy weight.

By the way I ate 1500 calories a day for five months and my muscle looked more impressive due to the fact that it had 60 lbs less fat covering it.

Jlanedc said:

While this information is great. I believe there is a different level of "starvation mode" that can be detrimental to many dieters efforts. It is fairly easy for your body to think it ay not get enough food and therefore put the brakes on efficiently processing the nutrients. In other words it will make getting rid of the calories consumed much more difficult as well as requiring much more activation energy to get up and running again. For many people in decent shape this is not a concern. I agree with being very difficult for your body to eat muscle due to starvation mode. But for the beginning dieter it is vital to keep a constant stream of calories entering the system. After all it is used to getting plenty of food and your body will get scared if something radical is happening. Radical in this sense could be not getting a fresh supply of calories every few hours.

October 23, 2011

Mark said:

The more I think about it, the more I realize what an amazing mechanism our bodies really have regarding energy supply and consumption.

I mean the one thing you might want to watch out for is adequate protein supply –and even for that you seem to have a 48-hour window!– but as far as calories?
You really simply don't need to worry about eating at all.

It's actually quite a funny idea to eat every couple of hours, like some hospital patient hooked to a life support system opr something.

I guess our bodies are a little smarter –and more efficient– than all that.

Thanks Rusty for once again providing AWESOME value info man, you ROCK, as always! ;-)

First time I've come across this, I guess there's a paradigm that revolves around the fitness industry and few people challenge it. I've been in China for the past several years and found that the Chinese have a much different perspective on fitness and health. They have one of the healthiest nations, in fact there was a bestseller written about Chinese health and fitness.

Hey question!

I have been doing insanity workout (I dont know if you have heard of it) and this is my second time doing it and I am into week 4. I started thinking I was going in to starvation mode because I was doing the training 2 times a day and resistance training in addition every other day. I don't know if its my imagination but it seems like my belly has gotten bigger which is very strange because the last few weeks I have been so busy with school and training and work I have had hardly any time to eat and when i do it its all healthy. (I'm also a vegan).

If I'm not in starvation mode can you give me an idea of what might be happening?

any info you could give me would be great.

Meade said:

I have quite a bit of body fat (230 lbs and 25%) to be exact. What has ruined my metabolism is from years of trying to starve myself. Now I find it near impossible to lose weight. I try everything. I just stay the same. Maybe starvation mode isnt true for some people, but it is true for others. And not extreme cases, either. If you restrict calories below say 1600 (if you are male), then over time your body will start getting better at storing fat. It will be harder for you to lose weight because it wants to hold on to fat , believing you are in a famine. This is why my metabolism is basically ruined. Im not talking about skipping a few meals every now and then. Im talking about what most dieters try to do , which is severe calorie restriction.

Thank you for this article! It is one of the very few that truly reflects what starvation mode is and why the vast majority of people will never have to worry about it!

Great post; very reassuring. I started doing intermittent fasting a few weeks ago, having been convinced of its many health benefits. But this further convinces me that there should not be any negative effects.

Yes; I agree with that Meade. Intermittent fasting and short term calorie restriction are no problem, but restricting calories too much for months on end will certainly slow down your metabolism. Though I believe there are ways to increase it again – HIIT and a nutrient dense diet for instance.

Those are some interesting findings. This clashes with my research that shows a shift in several different hormones when calories are restricted for an extended amount of time. I'll have to look into it further.

I get such horrified looks when I tell people "I'm fasting today." I'm already a thin person and people immediately think I have anorexia! It's great to have this article to direct them to and educate them. (I'm not dead yet!)

Great post there! Just to echo the other commenters thoughts – this pretty much flies in the face of conventional thinking!
I'm cutting at the moment so am severely restricting calories – hitting 1800 per day to be exact.
Still, what the article didn't mention is the fact that protein intake still needs to be adequate. Daily protein requirements will still need to come from somewhere – so sub 10% bf or not, you won't get away without consuming the right macro nutrients.

Hey,
Recentely discovered the site and love it. Enjoyed the initial abs blueprint videos. There was a graph in the video on eating that talked about Eat Stop Eat and Pilon's method. The graph was free fatty acid levels while fasting. It seems to say adapted from Klein et al 1998 or 1993. Anybody know where I can get a copy of that graphic or graph?? Or maybe where to get a copy of that research study? Thanks!

It made me realize that doing any weight-loss method excessively will only bring harm to my body. Thank you for posting this.

Thanks for the info! This definitely made me consider how much I am putting in my body. I'm trying to track my eating, so I stay healthy and eat when I need to. Even if I am on the go and busy.

Thanks!

I'm 13, 5' 2" and about 110. I have a little bit of fat covering my abs and i dont know what the best way to get rid of it. The reason i ask is because we are going to splash town for a field trip and i want to be able to show off my abs, last year i flexed the whole time and no one noticed but it killed my stomach. i dont know if i should count calories and do lots of running and bike riding for cardio to lose the weight or what

This article is very interesting. I have to admit I am just a little tiny bit skeptical… I am a 34 year old female trying to get my body back in shape. I am about 28% body fat… yeah I am a little chubby. I have been on a very low calorie diet for the last 6 weeks (first 3 weeks only consuming 500 calories a day, didn't have the energy to workout, the last 3 weeks increased intake to about 700-800 a day with moderate cardio) … lost about 20 pounds so far… the first week was awful, i was so hungry had no energy felt like crap. Lost 10 pounds but i know a lot of that was water. In the last 2 weeks I have been stalling but have not felt hungry whatsoever even on 600 calorie days. I was starting to wonder if my body was going into "starvation mode" and that my metabolism had adjusted to my low caloric intake. I am now considering increasing my calories up to 800-1000 and skipping cardio and just weight training. I was worried that I am losing muscle mass which is going to just hurt me in the long run and I will end up fatter than before. Anyone have any ideas for me? I am eating clean, mostly just eating lean proteins, small amount of high fiber carbs and fruit and veggies. I would like to break through this plateau and do what will serve me best in the long run.

If it were possible to just starve yourself for long periods of time and not lose muscle mass till you got to 5% body fat everyone would just stop eating go on the elliptical an hour a day and eventually get six pack abs. Obviously that doesn't happen – you just end up looking skinny-fat and become a twig that can't lift 5lb dumbbells if you do that. And I have personally dieted badly by over-restricting calories combined with large amounts of exercise – I lost 52 lb of weight but 8lb of it was muscle. I went from 30%fat@240lb to 14%@185lb – so nowhere near sub-10% body fat and my training and diet was nowhere near as extreme as this. I think IF can be used in a smart way in short 24 hour periods as long as it doesn't create an overly large calorie deficit – Intermittent Fasting is completely different ball game from Extended fasting with respect to muscle loss though – Just my 2c !

I knew it! How else could you explain all these "crazy" celeb dieting and getting in shape in no time!?

I remember how I traveled to Europe with just the right amount of money to eat a little during the day. I had to carry my heavy baggage with a bunch of clothes all around Vienna, Paris; running -with my baggage- to catch the train, the plane, etc. After only 3 weeks, what I had been trying to get in the gym happened: 6 pack abs. No proper workout, no ab crunches, no nothing. I just stopped eating so much. Obviously I'm a skinny guy so I didn't have to shed a lot of fat.

I didn't get any side effects afterwards. Just some skinny ass abs and a happy girlfriend ;)

So diet, diet, diet!

Starvation mode is a stupid myth created by companies which want to sell you useless supplements. Our ancestors didn't eat every three hours and most of them were probably looking better than most bodybuilders and fitness experts. Check Martin Berkhan's blog "Leangains" to educate yourself.
