Lots of things change after weight loss surgery (WLS), but perhaps one of the most important is your diet. After WLS such as the gastric bypass, what, when and how you eat are crucial to your long-term success.
Before a weight loss procedure, your doctor might ask you to eat in a specific way to lose some weight — anywhere from 5 pounds to a percentage of your body weight, depending on how heavy you are.
“We want to give you the best shot at success,” said Meredith C. Sweeney, M.D., a Norton Surgical Specialists bariatric surgeon who treats patients of Norton Weight Management Services. “This type of diet before is close to what patients will be consuming after surgery in order to ensure lifelong success anyway, so starting it before surgery only helps develop habits that can continue after surgery.”

For the first few weeks after surgery, you will be on a liquid diet. Fluids such as broth, water and sugar-free ice pops or gelatin to start with, then after 24 hours, you can add in protein shakes. This continues for about two weeks.
At two weeks post-operation, you will introduce soft foods including purees, hummus, scrambled eggs and finely chopped meats such as chicken. You still will supplement with protein shakes, and aim to get protein and other nutrients from food as much as possible. At five to six weeks post-surgery, you will slowly integrate tougher textures such as soft fruit and cooked soft vegetables, as well as some grains. This phase lasts through week four.
At five weeks after surgery, you will be able to eat what will become your “regular” diet. You still will emphasize protein at each meal, include vegetables and supplement as needed.
“There are some foods you might need to reduce or eliminate, based on how your body responds to them,” Dr. Sweeney said. “Those include carbonated drinks, spicy food and caffeine. High-sugar and highly processed foods will be greatly reduced as well.”
At this point, you will be able to recognize when you feel full after eating. It will be different from before surgery, and even from the first two phases.
Many patients report experiencing at least mild symptoms of one or more of the following after weight loss surgery.
“The most successful patients have a combination of tools,” Dr. Sweeney said. “They follow the nutrition plan, they pay attention to their bodies’ hunger and satiety (fullness) cues and they have the right mindset. If you haven’t done the mental work, it’s going to be much harder for you.” Dr. Sweeney encourages weight loss surgery patients to have a solid emotional and social support system, as well as changing their lifestyle to include more activity.
