I lost 40lbs effortlessly, eating as much as I wanted, and I've kept it for a couple of years now.. by switching antidepressants. the one I was on before caused weight gain and sugar cravings. I gained 40lbs when I started taking it and lost it when I stopped. I just suddenly found sugar and carbs unappetizing, whereas before I'd get intense cravings. the experience further convinced me that weight regulation is metabolic or something. I used zero self-control, diet or exercise, and a chemical change brought me back to a healthy weight. my eating habits changed but it was subconscious, not willpower.
