What should you eat after weight loss surgery?

Depends: What kind of surgery determines the kind of food to eat.

In General...: Weight loss surgery forces you to change how you eat, forever (unless you use a lap band, which may be reversible). You will have to get used to eating small meals because your stomach will be reduced to a tiny size. If you are ready to take it seriously, see a nutritionist and get started with a non-surgical program for weight loss because you will have to prove you are committed to your health.
