Question

eli5: If a morbidly obese person stopped eating entirely, would they be thin by the time they starved to death?

In: Biology

Answer 1

They wouldn’t survive long. While a body can survive off fat as caloric intake for the time being, without supplements, they won’t survive long. After the body uses its storage of sugar, the body can’t function. That’s why you feel so bad until you eat something after being super hungry. Following protein deficiency, muscles failing from lack of vitamins usually achieved from normal diet, a person would die no matter what their weight.

Edit: minerals as well like salt, potassium, etc.
