I understand that insulin increases appetite and that it has been used to treat anorexia. Yet another reason to consider a diet that minimises the use of insulin; if your intent is to manage weight
There is also biochemical evidence that higher levels of insulin moves sugar (as fatty acids) into fat cells - and locks it away there (as triglycerides) - so efficiently that it does it to the detriment of other cells... effectively leaving the body "hungry", despite the fact that you just ate!
