If you're obese and go on an exercise regime, you might think you'll just get fat again when you stop the exercise regime.
In the short term, that's probably true. But if you do it long enough, you'd expect someone who has exercised for many years to eventually develop better eating habits :-) And so it goes.
To a first approximation, nobody recovers from obesity. Less than 1% of obese people regain a normal weight through any kind of lifestyle change. What works, kind of, is bariatric surgery.
