A gastric bypass diet helps people who are recovering from sleeve gastrectomy and from gastric bypass surgery — also known as Roux-en-Y gastric bypass — to heal and to change their eating habits.

Your doctor or a registered dietitian will talk with you about the diet you'll need to follow after surgery, explaining what types of food and how much you can eat at each meal. Closely following your gastric bypass diet can help you lose weight safely.
