How could your metabolism slow down if you don't eat enough

Aphreal

I just don't understand why MFP yells at me that I'm eating too few calories if the weight I will b in 5 weeks is lower what does it matter if my metabolism slows down? Won't I still achieve the same results?

Um, no. Once your metabolism slows down you will basically have to eat like you're on a diet for the rest of your life, or you will end up gaining all the weight back, plus extra.

This is what I was looking for. The key is to eat as much as you can and still loose so you can eat more on maintenance and not gain. Want to eat 500 calories a day for the rest of your life because you starved yourself to a ridiculous size 0? That is what will happen. Go back to eating normally and you gain it back. You are stuck with next to nothing because that is how you trained your body.

Exactly.

Say a typical anorexic eats: an apple for breakfast, dry salad for lunch, and dry cereal at dinner or maybe a can of tuna for dinner coming up to no more than 350 calories a day, with verrrry little fat.

Say you don't eat much: You grab mcds bfast sandwhich, soup for lunch, and noodles for dinner your around 800 calories.

But the anorexic is eating little with almost no fats and greases so the body doesn't have fat to cling too.
When you eat very little but still manage to eat enough calories to slow the body with unhealthy grease and fats it clings to them longer.

No, just no. 800 calories would not be enough to keep the body from slowing down. And fat gain/fat loss isn't dependent upon whether or not you eat unhealthy grease and fats.

As well as weight, you will also lose your hair, any energy you previously possessed, long-term health and possibly your life. Yeah, I'm totally tempted *rolls eyes*
