Not sure where you have read, or who told you, that the body wastes muscle-tissue instead of fat while fasting; but I would agree with you that fat is utilized first and foremost before any vital tissues are autolysed for sustenance.
The body will innately consume those food reserves in the least order of importance before eventually turning to muscle tissue as food.
The most overweight person will tend to lose the most weight during the beginning stages of a Water Fast as opposed to the thinner individual, where the body will economize what food reserves are on hand.
Totally agree with your post.
Well done on losing your cellulite.
You have given a lesson here for everyone wanting to rid themselves of unwanted fat and cellulite naturally, without resorting to surgery and liposuction and the like.
