Long term drastic calorie restriction simply does not WORK for fast fat loss. It requires a HUGE amount of sacrifice, and frankly, the results don't even come close to warranting the effort.
Ever seen an anorexic? Probably not the look you're going for...
So if a massive calorie deficit must be present to achieve rapid fat loss, and long-term minimal calorie intake can NOT work for fat loss, how CAN you create the necessary deficit without having your body turn it's back on you?
