if a morbidly obese person suddenly stopped eating anything, and only drank water, would all the fat get burnt before this person eventually dies from starvation ? How much longer could that person theoretically survive as compared to an average one ?

Question

Currently on a diet. I have no idea how this weird question even got into my mind, but here we go.

Answer 1

He would survive much longer than an average person as his body will have a huge supply of fat to use as calories. His muscles and organs, etc. would begin to deteriorate as the energy reserves stored in fat is not sufficient to maintain these. Poteins are needed for repairs as these are used. There are also other nutrients required for various functions, especially the brain.
