A gastric bypass diet is a diet created for a person who has just had surgery for weight loss. The gastric bypass diet is very strict, and usually the patient cannot eat for 2 days after the surgery has been performed. It all depends on the doctor's recommendation and your health status. Always have a doctor recommend what foods are best when going on a gastric bypass diet. You'll need to eat small amounts of food, as many people who have had this surgery cannot stomach very much and sometimes even throw up after eating...
