A post-bariatric surgery diet helps people who are recovering from sleeve gastrectomy, gastric bypass surgery — also known as Roux-en-Y gastric bypass — and other bariatric surgeries, to heal and to learn new eating habits for life after surgery.

Your doctor or a registered dietitian will talk with you about the diet you'll need to follow after your surgery, including 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 and keep the weight off in the long term.
