One self-regulating thing really does exist. If you are already overweight, the body can self-regulate itself, by extracting fewer calories from processing from eaten food. You can take in food for 3000kcal, but the already overweight body can take in just 2700. This has only one effect: when a person decides to lose weight, it'll make it harder for him, because eating slightly less than will have no effect at all, and the body is already used to eating a lot, so reduction in incoming food brings immediate discomfort. But the opposite direction is rock solid: if you don't eat enough to compensate your passive calorie burn, you will not gain weight ever. Anyway, this method helped me to go from 96 kg to 83 kg in 10 weeks, taking on average 1750..1900 kcal per day. For me it turned out pretty easy. First two weeks were the hardest, and I took in up to 2000 kcal, gradually bringing it lower.
