These "layers" mean a variety of skin folds (populally called the unprettious Word of the Specks), which make your life more unpleasant and give an unsighted impression if you are trying to dress in a nice outfit not falling into excessive sizes. Moreover, these layers are visible to the naked eye and have their internal counterparts – fat, which settes not in the subcutaneous tissue, but wraps our organs and slows down their activity.
In winter you should warm up with warm coats
A ketogenic diet is a dietary system with which you can achieve a significant loss of fat layers both on the surface of your body and also within the organism itself, in a relatively short period of time. So forget the excuses of the type "winter protection from cold" and instead of skin eyelashes, get a warm coat.
