Starvation mode hysteria

bump

I'm currently enrolled in a Nutrition and Meal Planning class in my college. When you aren't receiving enough calories your metabolism slows in order to store fat so you don't die from starvation, it holds the fat in sort of a reserve. However, this only works up until a certain point until your body begins to HAVE to eat away at the fat in order to survive. That's why people in 3rd world countries, etc are so thin. Your body can only reserve so much before being forced to eat away at those reserves.

and if you do the math and look at how much metabolism is reduced, its easy to see why this slow of metabolism doesnt matter.
WORST case it is about 10%, and thats for a LEAN man, its much less for someone overweight.
so you drop calories a bit more, and.. its like it didnt reduce at all, the loss continues.. although once you have dropped low enough, you also start to lose lean body mass... at this point (for everyone, not just men) the challenge becomes to maintain LBM while continuing a caloric deficit to force the body to burn fat... of course this means activity that doesnt exceed the rate the body can metabolize fat... and why someone on a PSMF diet shouldn't be doing cardio.. but whatever.
To be honest I never want to share what I know because for me to put anything useful on here, it becomes a huge post... I could probably write a book on it, but It wouldnt be my own research, just a compilation of other research regurgitated again. Im sure because I abbreviated that into a few sentences, someone will take it out of context and *****.

Here's a study showing BMR dropped by over 20% during severe caloric restriction, so I have no idea where you got this 10% number from, or why you're even pushing it like 10% isn't a very significant reduction in overall metabolism. A 10% drop in function is HUGE.

"function"?? define function.
a 10% drop in the number of calories burned is no big deal, especially since it bounces right back after you start eating normally again.

and i was incorrect, the limit was 30, 10 is what the average obese person loses.
read chapter 9 of this PDF its in paragraph form, references for his sources are at the bottom.

The thing is, according to his own posts, the OP is in a HUGE daily calorie deficit, but only managing to lose what he'd lose if he was in a 250 daily calorie deficit. (About 2 pounds a month.)

That right there is all I need to know.

then by definition, he would only be in a 250 calorie deficit, not a huge one.... ?

He says he eats 1500 calories, doesn't eat exercise calories, and burns 1000 at the gym. If that's only a 250 calorie deficit, he's got some serious metabolism issues.

If hes not losing weight, then hes probably consuming more then 1500 calories, and burning less then 1000 at the gym.

Very likely a combination of the two.
