I’ve never understood how extended caloric restricted diets are supposed to work without continuously losing weight. I understand that if you eat under maintenance you may lose weight and have a lower maintenance level and stop losing weight but then doesn’t it stop counting as calorie restriction?
I've never done it, but I believe your body will adjust its metabolism to match your calories, eventually. Otherwise, you would continuously lose fat and muscle until you die, so yeah you can't eat under what you're body is using forever.
