"Starvation Mode"
Replies
-
I ate 1200 calories a day for quite a while and lost on it, then I couldn't lose weight anymore. I had lots to go still, but nothing was working. So I read a lovely forum post by helloitsdan, and upped it to 1630 and now I steadily lose 2lbs/week. I also have more energy, sleep better, feel better. I feel like this is something I could do for life now.
I think a lot of people get hung up on the words starvation mode, but really it's your metabolism slowing down most of us are talking about.
It's all about balance! When has it ever been good to be either too far right, or too far left, of any issue anyway? :P0 -

Correct. HCG is a hormone produced during pregnancy and is banned due to its potential to give one cancerous tumors. HCG that is sold in walmart is water with additives to keep you barely alive long enough to empty your bank accounts. A very dangerous fad diet.0 -
I agree i also think starvation mode is a myth At least until you get to a very low percentage of body fat... Its very popular these days but dont be fooled it really is a myth If starvation mode were really true no one would be starving in the world their would be no anorexics. People need common sense .... Why would you body hold on to fat for dear life. and your metab come to a sudden hult Nope.. it might slow but you can speed it up by exercising and eating every few hours.
It's not about what you're eating...it's about hormones! Hormones can tell a morbidly obese body to hold on to all that fat even though that person is no where near starving.0 -
"Starvation mode is a myth. It was popularized due to the Minnesota Starvation Experiment (http://en.wikipedia.org/wiki/Minnesota_Starvation_Experiment) in which subjects were given 50% of their daily calorie intake for months. The result? Well, they lost weight until they had almost no weight left to lose and their bodies simply could not get the calories ANYWHERE. Concisely put: starvation mode happens when you are, quite literally, wasting away. Not when you have a simple caloric deficit. Your body will make up for it with fat stores. That's what they're for. Do not worry about starvation mode (http://examine.com/faq/how-do-i-stay-out-of-starvation-mode.html)."

Yes it's a myth if you have significant fat reserves.
If you have a lot of body fat reserves you would be surprised at how little you can eat (unless you have emotional eating issues or disorders). The leaner you get the less your body has to draw from and then you have to taper up your calories. There is no such thing as starvation mode for woman over 12% body fat or men over 6% body fat. I pretty much proved that for myself by staying strong and building muscle and doing what I did. I'm the leanest, most muscular, and most fit that I have ever been in my life at almost 52 years old.
Seperating out the the two things worked for me:
1) Eat less to lose fat.
2) Exercise to gain or maintain lean body mass.
Ignore exercise calories because it's insignificant when you don't have to worry about starvation mode anymore and it's highly over rated. Of course you burn energy, but not nearly what any of the devices say you do.
If you are not doing a weight training routine you need to start one and do it the rest of your life to ward off osteoporosis.

Kinda sorta. Really, these forums are potentially dangerous due to the amount of absolutes (you can't do that, do this). People need to go get blood tests and a physical to determine dietary requirements.0 -
its sad but its the only way i have ever lost weight. I have tried many diets and healthy eating. yet my body doesnt want to go below a certain weight...I have to make it....I think every body has a ideal weight the problem is this isnt always satisfactory to us...it isnt to me..I want to be slim and my body wants to be curvy..not over weight just not how I want:(So i have to go to those extra lenghts to loose those so called vanity pounds. just like a girl who cant gain weight easily has to eat a heap to gain an extra few pounds.0
-
I have also heard that if you don't eat enough calories that your body stores them because it doesn't know when its going to get it next meal.
Example, would be not eating all day and then eating a large dinner.
Then explain anorexia. Those people are skin an bones yet they still lose so much that one day it's their life.
Anorexics actually so little that it doesn't matter, their body eats fat, muscle, and whatever it can instead. They don't ever eat the fat for their body to store in the first place.. Also, some anorexics aren't as skinny as you'd think, especially people that have anorexia and bulimia.0 -
I agree with this who knows if the drops really do work.
It could be just the 500 a day and healthy eating...
So their is proof right their that their is no starvation mode.0 -

I ate approx 1000 calories a day for two years, sometimes less, sometimes only one meal a day, when I was obese and over weight. It was not fun but it did not hurt me. I had the fat reserves for it. My hormones were fine, my doctors said I was healthy. Now I'm under 12% BF and I can't eat that low but I still eat pretty low because I'm small, my RMR is low. I just had my blood work done and my hormones are all just right still.
"The Reverse Taper Diet " :
The Theory of Fat Availability:
•There is a set amount of fat that can be released from a fat cell.
•The more fat you have, the more fat can be used as a fuel when dieting.
•The less fat you have, the less fat can be used as a fuel when dieting.
•Towards the end of a transformation, when body fat is extremely low you
may not have enough fat to handle a large caloric deficit anymore.
At the extreme low end, when your body fat cannot ‘keep up’ with the energy deficit
you've imposed on your body, the energy MUST come from SOMEWHERE. This is
when you are at risk of losing lean body mass during dieting (commonly referred to
as ‘starvation mode’). This happens at extremely low levels of body fat, under 6% in
men and 12% in women [Friedl K.E. J Appl Phsiol, 1994].
Oddly enough, it seems as though some obese people have an unbelievable amount of fat available as a fuel, but a lower ability to burn that fat, whereas as they get leaner, they have less and less fat available as a fuel, but a greater and greater ability to burn the fat they do have. So at extreme levels of leanness, it is the fat availability that limits a persons ability to lose fat.0 -

YES. The magic of ancient Chinese dragons come to boost your metabolism in the night

Interesting reading. Back in 08, I lost 40 lbs in 5 weeks, I ate less than 2000 calories in the first 14 days TOTAL and then all I took in on average was 500 calories in juice per day. My situation was stress related due to a personal situation, but proves you can loose weight if conditions are right. I will say that I put it all back on PLUS 20 lbs within 8 months after getting my head right. Bottom line, starvation will take it off, but wont keep it off in my opinion.0

They also walked a minimum of 22 miles, burning approximately 3000 calories each week while maintaining active jobs during the entire 6 month period. You missed that.I would like to point out that each subject ate approximately 1,560 calories per day (hardly starvation) which is 30% higher than many people on MFP are consuming.
http://en.wikipedia.org/wiki/Minnesota_Starvation_Experiment
So let's break it down..
The typical TDEE of a man back then was around 2200. By eating 1570 calories, that's a deficit of 630. A minimum of 3000 calories from exercise a week translates to 429 exercise calories daily. Thus, their total deficit was about 1059 calories which would give them an energy availability score of 1141 calories (net). That's roughly a 50% deficit.

Okay, that worked for you but it may not work for different people. That is why they should get checked out by those that specialize in such areas. Also, congrats on getting featured on bb.com.0 -

Humm could support the idea an earlier poster had that she (her mind) and her body disagreed as to what her ideal weight was. Seems genetics would go to the amount an placement of fat cells, ergo body shape etc. How many you have would determine how low you can go or how fast you can lose. Just a thought.0 -
if you are overweight and eat less than 1200 calories a day and exercise you will continue to lose weight and anyone who tells you that you wont is LYING.
you can always lose weight by starving. you will, however, be extremely unhealthy, weak, lethargic, cranky, upset and moody, have emotional problems, possibly even collapse from exhaustion...long term you might get kidneystones, hair fall out, lose your period, loose teeth etc etc
finally, the number one reason not to starve your self is that the day you decide to eat like a regular person and have a normal meal you will gain like 8 pounds and keep gaining and it sucks!!!0 -
My thoughts are directed at those who say they loose and are happy on 1200 cals a day or less mainly. I just wonder why really? I don't honestly think anyone (unless you are a mini person) needs to eat at that kind of deficit to loose fat. I think it's been proved again and again that you can loose on a higher amount of cals (obviously this amount varies per individual) so why would you choose to eat less when it's not needed?0

Not long term you won't. And I beg to differ but I am not lying. Care to explain to me how I ate at this large deficit for the past 16 years yet am still overweight?0 -
Speaking only for me, i have no choice. I GAIN at 1200 or above. I tried the metabolism reset. After 5 weeks at at TDEE i tried eating a "reasonable " amt for a few weeks and kept gaining
No thyroid or med issues. I WISH i could eat more and still lose. Maybe others are in the same boat as me 0 -
Starvation mode (it’s not actually a defined term) as it is used on this site usually means one of three things:
1) Weight loss stops no matter how low calories go: You will not find any studies that show this to be true.
2) Metabolic adaptation: Outside the impact of short term fluctuations and water retention due to hormonal imbalances there are studies that indicate a lower BMR due to VLCDs outside that normally seen by weight loss itself. As far as I am aware the studies are not conclusive as to the extent but I believe one study showed an approximate decrease of 5%.
3) Greater muscle loss than experienced on a reasonable calorific deficit.
It helps when clarifying exactly what is being defined as ‘starvation mode’
With regard to The Minnesota Experiment, it was a study into the effects of starvation, not in relation to the context it is usually used on this site. It was conducted over 60 years ago (in 1945) and there was no BF% tested (as far as I can tell, and even if it was, techniques nearly 70 years ago were not accurate, heck, they are not totally accurate now), and as such, no testing of LBM loss. Secondly, the average intake was over 1,500 calories which is debatable as to whether that is a VLCD.
I would also like to point out that most of the people who participated experienced severe emotional distress and depression (including self-mutilation in some of the subjects), decreases in libido, concentration and mental capacity. There were also sigificant declines in their BMR.
However, all in all, the experiment indicates to me that VLCDs are a really bad idea
I do agree that this, as well as other studies and experiments, indicate that in the context of the definition in 1) above, yes it is a myth. In the other two definitions, you will find a different answer.
You mention in your OP that your that your body will use fat stores before muscle – this is contrary to the way weight loss works. As a natural part of losing weight, we lose LBM.
See a study that has been misquoted or misinterpreted a lot to try to indicate no muscle loss on a VLCD:
http://www.ajcn.org/content/83/5/1068.full which is a study conducted by Freidl et al. What the study actually shows is that you will lose LBM.
In addition there is another study from the same group.
http://www.ncbi.nlm.nih.gov/pubmed/10797147
From that study, I point you to : <snip> After 8 wk, most of group 1 achieved a minimum body fat, serum 3,5,3'-triiodothyronine (T(3)) was below normal (78 +/- 20 ng/dl), testosterone (T) approached castrate levels (4.5 +/- 3.9 nmol/l), insulin-like growth factor I (IGF-I) declined by one-half (75 +/- 25 microg/l), and cholesterol rose from 158 +/- 31 to 217 +/- 39 mg/dl<snip>
I particularly like the castrate levels of testosterone!0 -
People shouldn't rely on the he said she said and ask someone who really knows. I'm an RD and I know for a fact that "starvation" mode is real. Your body really will fight to maintain a constant weight, by adjusting the metabolic process. That's why it is also hard to lose weight because your body is in a struggle to maintain a sort of "equilibrium".0

I *COULD* lose weight while eating less than 1200 calories. Hell, I did. And I got to my goal weight. Eventually. And I also still had back fat rolls, a double chin, a muffin top, ginormous thighs and zero muscle definition anywhere on my body.
I ate almost twice as much this time and lost the same amount of weight, a lot more effortlessly, and faster, and look a lot better, too.
I used to believe I had a crappy metabolism and had to eat under 1000 calories to lose. Boy, was I wrong! :happy:0 -
*edit* double post... forum hiccup.0

I have yet to see any proof of starvation mode other than anecdotal evidence0

OMG! Someone made a forum post on a weight loss site. This has dramatically changed my way of thinking. Yeah, no. People need to stop offering unwanted advice they read on the internet.
^^ rude and glad were not friends.0 -

Well, I would say that if someone invents a time machine, I will gladly go back in time to have a scientist document how stupid eating screwed up my body... but if I could go back in time, I'd really rather just do it right the first time instead. :laugh:0 -

Read the whole book, read up on Ancel Keys. I will share my thoughts then.0 -
Your body holds onto fat because that's its survival mechanism when there is no food. You can survive a famine much longer with more fat and less muscle than you can with more muscle and less fat, so the body sacrifices muscle first. The human body doesn't understand the concept of dieting. It only understands that there is no food available, so it needs to conserve as much energy as it can in order to keep you alive until food is found.I agree i also think starvation mode is a myth At least until you get to a very low percentage of body fat... Its very popular these days but dont be fooled it really is a myth If starvation mode were really true no one would be starving in the world their would be no anorexics. People need common sense .... Why would you body hold on to fat for dear life. and your metab come to a sudden hult Nope.. it might slow but you can speed it up by exercising and eating every few hours.
And exercising and eating every few hours doesn't speed up your metabolism, that's a complete myth.0
