The gastric bypass diet is designed to help you lose weight and keep it off. Most patients will lose up to 50 to 80 percent of their excess body weight within two years. However, if you do not follow the nutritional guidelines, your weight-related health problems may not improve, and increase the risk of developing new health problems and even gain the weight back.

You must take your time while eating and drinking and recognize when you are full. Stop eating at the very first sign of fullness. One more bite can cause stomach pain or make you vomit.
