Earlier this year I came across something interesting online, can't recall where it was located. Either a doctor or a nutritionist or some similar 'expert' was explaining that dieting very RARELY makes anybody ill, and that during weight loss, the cells release their protein and that's why it's safe to diet.... but, that afterwards, when one is no longer losing weight, that one's protein needs are substantially increased, because one is no longer burning one's own stored protein.
