eating and puking

[cozmokramer]

Why is it that I always read that people that eat a ton and then throw up don't lose weight...?

I would think that the throwing up after eating removes calories creating a calorie deficit... so doesn't a calorie deficit create weight loss...?

If you're referring to bulemics, yes they do often lose weight. They also have a mental illness that can kill them. Fasting or purging are ways to teach your body to retain fat and burn muscle---very destructive and stupid.

why does bulemia tell your body to keep fat?

 

[PimpnAintEasy]

Muscle is metabolically expensive to maintain. When you body perceives that sufficient calories are not going to be consumed, it will retain fat much more stubbornly as a survival mechanism. Protein/muscle is subsequently broken down used more rigorously as a fuel source for the body leading to a very catabolic environment. When caloric consumption returns to normal, fat will be added rapidly, however the muscle mass is lost. Terrible tactic for bodybuilders, it's really a sickness.

The trick is to speed up metabolism by eating frequently and cleanly while maintaining a sound training regimen.

What made you think of this question, hopefully not considering this are we?
