Diets do not work long-term. They make you fatter and crazy. You will take the weight off and put it back on again. If commercial weight-loss plans really worked, you'd do them once, lose the weight, and you'd have corrected your "bad habits" for life.
But they don't work that way. They give you an unrealistic standard to live up to so you'll fail and keep pumping more money into the multi-billion dollar Weight-loss Scam industry.
And dieting often leads to disordered eating, compulsive eating, compulsive exercising, compulsive obsession with food and being "good or bad."
If you still think you're going to change your life through dieting, fine. I just don't want to hear about it. If one more person tries to convince me that Weight Watchers is a wonderful way to "modify your lifestyle" and it's not a "fad diet" I will start screaming like a crazy woman. So, please. Just. Don't.
