Personally, I'd forget about food combining for weight loss. It's usually a good sign of a fad diet and has not been proven to work. Unless you mean food combined with exercise
Most of the diet plans that suggest doing it are actually just feeding you a reduced calorie diet, and
that's what works. Burn more calories than you consume, and you'll lose weight
What kind of diets have you tried in the past? What kind of foods do you like?
