I have absolute faith that eating the way I do now I will never end up fat again, ever. It's not even a question of maintaining my exercise level or counting calories. My weight has simply reached normal because I'm getting the nutrition I need, not because I restrict calories or burn it all off exercising.
Perhaps people who find this difficult like a diet are striving for more than just a normal healthy weight, like 6-pack abs or a figure like a model.
