Tell me about 'starvation mode' or metabolic slowdown

I always read about this 'starvation mode' we go into if we starve ourselves or if our caloric deficit is too high. How exactly does this metabolic slow down occur? If you go 6 hours hungry say during the day would you go into this mode, or does it take a few days of extreme caloric deficit or even a few weeks? I've always wondered about it because when I'm dieting/cutting I don't want to go into it if I could be eating MORE and keeping my metabolism up for better gains. So any detail/ non-technical sources would be great.

starvation mode comes on from various hormone levels dropping - leptin, etc if you go low enough, your body starts shutting down "un-needed" functions, like your reproductive and immune system, since it is trying to conserve as much energy as possible to sustain you till you find food again. metabolic suppression is limited to about 30% of normal.

Ok, and how long does it take to onset at each level of caloric deficit? For instance does it take longer to set in if you have a caloric deficit of 700 vs 1500? How long does it take to set in generally? The metabolic slowdown.

shastaisforwinners your body starts shutting down "un-needed" functions, like your reproductive oh fawk I'd never mess with that

there is a chapter about this in the Rapid Fat Loss Handbook

QBoost Controllers Ok, and how long does it take to onset at each level of caloric deficit? For instance does it take longer to set in if you have a caloric deficit of 700 vs 1500? How long does it take to set in generally? The metabolic slowdown. varies depending on a lot of factors... how sensitive you are to leptin, whether you are using drugs (EC, bromo, etc), whether you were in a caloric deficit prior to this diet, the list goes on. Generally, the more severe the deficit, the more metabolism will slow. Generally takes your body a few days to adapt, even in severe deficits. Leptin levels will generall fall within 3 - 4 days, and takes a solid 2 days (or more) to raise it. That's the idea behind diet breaks and/or refeeds. edit: This is a vary simplified generalization of what happens, btw

Ceaze there is a chapter about this in the Rapid Fat Loss Handbook yeah, read the Rapid Fat Loss Handbook and the Ulitmate Diet 2.0. Both explain this stuff in good detail, but in an easy to understand way. Recommended reading for anyone that plans on dieting.

Any more info I dont have this book...

superbri007 in the age of us having ample amounts of food, ther eis no reason to do this. Cavemens bodies did this, just out of nature when they would go on long periods of starving before they caught food. of course there is no reason for our bodies to do this anymore (well, maybe in Etheopia and whatnot), but physiological adaptations will take thousands, if not millions, of years before 'starvation mode' isn't an issue anymore. Of course the human race will probably be extinct by then, but stil...

mmmmmm.....sushi refeed tonight. Yummy.

edmang http://www.bodyrecomposition.com Yeah..or that one..heh. Thanks for the correction :P

i thought it had more to do with eating just one or two big meals a day than with a caloric deficit.

dank i thought it had more to do with eating just one or two big meals a day than with a caloric deficit. no

Flexible dieting, Fat Loss book, UD 2.0 all have this info.

ACURA TL-S mmmmmm.....sushi refeed tonight. Yummy. 40 pieces for me last time. Felt good Couldn't eat the fatty pieces though.

shastaisforwinners no so your metabolism would be the same eating 1 2000 calorie meal per day vs. 5 400 calorie meals?

dank so your metabolism would be the same if you ate 1 2000 calorie meal per day and 5 400 calorie meals? its about the same if you eat 3 versus 6.

AznRyda its about the same if you eat 3 versus 6. so why eat 6 meals?

Individual reasons. People can't eat big meals. People feel better eating tons of small meals throughout the day. People are on a calorie deficit so having 6 tiny ass meals is not satisfying, etc etc. People worry way too much about minor stuff.

dank so why eat 6 meals? if you are dieting it helps to keep you full all day and not have cravings

gsteclipse97 if you are dieting it helps to keep you full all day and not have cravings I guess. I was hungry yesterday, and I ate a small 200 calorie meal and it was nothing. if anything, it made me more hungry.

whatever, any given question on this forum gets a random different answer each time.
