It’s an astonishing amount of weight to lose in such a shortage period and I’m sure it is very encouraging for him, but these very low calorie diets can’t be sustained indefinitely and therein lies the problem.
Unless he addresses his normal day to day food consumption, the weight will inevitably go back on won’t it?
I’m pretty sure the advice is to just cut down a little bit so the body isn’t thrown into survival mode where every calorie is stored as fat.
The advice is usually to aim for a loss of one pound a week, no more.
