starvation mode

http://authoritynutrition.com/starvation-mode/
"This is a natural physiological response, and isn’t really controversial. It is well accepted by scientists, and the technical term for it is “adaptive thermogenesis”"
"Starvation mode is real, but it’s not as powerful as some people think.
It can make weight loss slow down over time, but it won’t cause someone to gain weight despite restricting calories."
un-bunch your panties.

However real adaptive thermogenesis is, it doesn't cover the "am I eating too little to lose any weight" posts that are legion here.
This is what I've always understood it to mean, when I've read about it, and what people I've discussed it with in real life have meant when they've referred to it. It's just a layman's term for adaptive thermogenesis.
People on these boards often take it to mean something else (although people here also almost always assume they are using it incorrectly, and say "starvation mode doesn't exist", when the term does exist and refers to something real).

I hear ya, it just might be more accurate to say "I don't think it means what you think it means" than "it doesn't exist".
I will say - whenever I've eaten very little (for whatever reason), I've lost weight very quickly. (Not recommending)

I am currently experiencing the flu as a dieting method. I've lost a lot of weight in a very short amount of time. I've been eating... just not a lot.
Would not recommend.

I experienced the same with shingles. Also would not recommend.0 -

Yuk, I hope you feel better soon.

I think it's just the part, "your body holds onto your fat" that gets me. If you're not eating anything and your body "holds onto the fat cause it thinks you're starving" doesn't make any sense. Just like the myth about eating breakfast. Everyone eats breakfast, it's the first meal you eat upon waking up, whether it's 6am, 12pm or 6pm. That's why it's called breakfast. You're breaking a fast.0

But, why does your body only burn so much fat per day before it starts burning muscle instead? In a sense, doesn't it try to hang on to fat if it thinks your starving it? It's not that you won't continue to lose (and lose fat) on a deficit, but you'll lose too much muscle if you go too extreme.0 -
you got a point there. I guess that's why eating protein and strength training is so important.

I know right but you see it here all the time..."you're in starvation mode" when an op complains they've been dieting for a week or two and haven't lost anything....it's a "SMH" moment for sure.
I regularly eat less then a 1000 calories and have for many months. I am also active when not at work. Also working out 3 times a week. I have
Not lost a single lb. In 5 months.
When I hear/read ppl say reduce cals and you will lose weight it pisses me off. Stop generalizing not all bodies respond the same way. Same goes for the crap around BMI.0 -

Yes, I'm happy to have found these boards for that info in particular (probably not a huge secret, but I wasn't that aware, at least about protein).
As for starvation mode - it is funny how many people think that you actually won't lose weight if you eat too little. That really doesn't make sense.

Thanks. I'm super annoyed to get it so relatively late in flu season. I got vaccinated in September!

So you're meticulously tracking that intake are you?
You've ruled out any medical conditions?
There's always a reason the scale doesn't move. Always.

Wow, usually the vaccine gives you the flu a lot sooner!

Strong first post.

So you're either saying your body can create energy out of nothing or that your body burns less than 1000 calories per day.0 -

There are limits to how quickly fat stores can be converted to energy. Exceed those, and the body has to go elsewhere.In a sense, doesn't it try to hang on to fat if it thinks your starving it?
No.

No.
Ok. It was a question because I was wondering, I haven't studied it much. I was assuming the time limit on fat store conversion was based on some evolutionary reason (protecting the body).

There's your answer, and I think he's right- your CO was off. My Fitbit drastically overestimates my burn. There is no true way to know how many calories you're burning. IMO a Fitbit is just a step counter.
I used the Fitbit before changing the CI side and was losing. I used the Fitbit after returning to higher intake and was losing. If the Fitbit and the CO side was off and causing me to gain, then surely I should have been gaining even faster when I was eating even more.
Then again, if I'm eating less than RMR, then I should lose even if I didn't exercise at all, right?0 -

Your experience doesn't make any sense. To gain 6 pounds in 3 weeks you'd have to have been at about a 1000 calorie surplus daily. At what is around a grown guy's BMR, that would be a sudden drop to a TDEE of less than 800 calories.
Correct, it doesn't make any sense... unless my RMR adjusted to a lower calorie intake (i.e. starvation mode). Is that what it was? I don't know - it may have just as easily been water weight. Just because you don't understand it does not mean it didn't happen. My point was that since this happened the last time I ate consistently at such a low calorie level, I'm not going to do it again. I'll eat at less than TDEE and above RMR and lose weight.0 -

Totally agree. Generally if you aren't losing, it's time to crank down the caloric intake. There are some exceptions, but I suspect the biggest issue is incorrect logging of food causing more calories to actually be eaten than is being logged.

Fact of the matter is .. Fasting raises your metabolism.

I think both of these article are bad examples of what is being talked about.
First article uses lean population. So for majority are we lean to follow this study?
Second article talks about adrenaline release after 48 hours of no food.0 -

Your TDEE doesn't just drop by over 1000 calories because you ate under a number determined to be about what you would burn if you were sleeping 24 hours a day.0 -

I'm not saying it did. What I'm saying is that I gained weight when I decreased calorie intake. The only change I made was decreasing calorie intake. I didn't change scales (including food scale), I didn't get a new activity tracker, and I didn't even change the kids of foods I was eating... just ate less.
I'm also not saying I understand why. In fact, I've clearly stated several times that I DON'T see a scientific reason to explain the actual results.
There are a lot of people out there that believe the CICO equation is the only explanation, and that if something happens that cannot be explained by such equation, then it cannot be possible. They believe that there must be some other explanation, and they jump to the easy answer that someone is lying (or at least unintentionally eating more than they are logging or exercising less than they are logging). That isn't the case for me. If it were, I should have been gaining even faster before I decreased calorie intake, right?! I'm not going to jump to conclusions because I don't have enough data, but I'm going to leave open the possibility that a "starvation mode" does exist and can explain my gain at decreased calorie intake. I'm not saying that is what it is, but it is possible. In fact, it is the only possibility that I can think of (but that still doesn't make it so... just like if your knowledge tells you that my results are not possible, it doesn't automatically mean I'm lying).0 -
@midwesterner85
There are reams and reams of data that indicate starvation mode simply doesn't exist in the way you're talking about and reams and reams of data that indicate that under a verified caloric deficit, you will lose weight.
As between "you're a special snowflake," "you've made a mistake somewhere in your measurement," or "it's possible to gain weight outside of normal fluctuations when in a caloric deficit," the middle one is, by far, the most reasonable explanation.
If you believe this not to be the case, you should probably contact a research facility and become world famous for defying physics.0 -

A scientific explanation exists for what happened to me. I don't know what it is, and clearly you do not know what it is. I know what it isn't: inaccurate logging.0 -

You 2 are aware that coffee can be made at home, are you not? You can make a great cup of coffee for $0.35. At home.
What? I buy custom roasted coffee - it's not roasted till the day before shipping. Can't handle that stuff that's been on the shelf for so long someone has to dust it off to make it look presentable. Costs me about $1 an ounce (more depending on the roast - especially Kona from Hawaii closer to $3/oz) and I drink a lot of ounces.0
