Re: Tw: Eating disorder/food issues -- VERY TL;DR

Except "starvation mode" doesn't actually exist if you have a high enough body fat percentage. Adaptive thermogenesis will slow your metabolic rate down some, but you'll still lose weight if you're eating at a caloric deficit. It won't stop altogether, and you definitely won't gain weight. If that was true, you'd see a bunch of overweight concentration camp survivors.

I almost don't even want to dignify this with an answer, but.

Obviously I mean once said person stops eating at a deficit. FFS.

And yes, starvation mode exists regardless of body fat percentage. It's a biochemical function of glycolysis inducing the Kreb Cycle generate ketones in times of insufficient glucose intake (ie. ketosis). Insufficient calories to sustain basic metabolic requirements (which is a function of what your typical caloric intake is rather than a set value per weight/height) allow fat stores to be released, yes, but this doesn't actually result in meeting optimal glucose requirements. Gluconeogenesis just isn't energy efficient enough to provide the ATP requirement to sustain itself and to sustain all organ functioning at optimal rates. Hence why the term "starvation" even exists.

You can be as fat as you want and still be starving, and your body will react accordingly.

Well, yes, obviously you won't be functioning at an optimum rate. If you mean starving as in not having the nutrition you need, then yes. But if a fat person doesn't eat they're going to burn excess fat before they die from lack of food. In my personal experience that's what people usually mean when they talk about starvation mode ("I must eat every 3 hours or my body will go into starvation mode and I'll die!"), but that's obviously not what you're talking about.

It's really not, no. I'm talking about it in the medical sense, both metabolic changes that occur and endocrine changes that follow.

The post-game scenario - in the broadest of terms - is that as soon as the caloric deficit is decreased (ie. you stop restricting calories to 1000kcal/day) the compensation measures that the body has been taking result in disproportionate weight gain to what would normally be seen with an equal caloric intake in a person whose body had normal metabolic functioning.

Hence the term "yo-yo dieting". Only, in OP's case it's even more extreme and more damaging.

Hell, I've lived through that. It was only after I adopted changes to my exercise regime and started eating consistently that I finally started to get healthy again.
