Weight Loss Surgery Diet

Stage 3 - Pureed Diet

Posted: 10/4/23Updated: 2/8/24By Jason Richardson, MD

Following the full liquid diet, patients often enter the third stage, which also lasts for 2 weeks. The pureed diet consists of soft foods that have been blended until they become very smooth and easy to digest. Pureed foods can be made from vegetables, fruits, dairy products, and even some meats if you have a sufficiently powerful blender. Patients should continue to avoid any solid or chunky textures during this stage. Remember to cook (consider steaming) the food until it is soft and easy to mash before pureeing it to make it suitable for a pureed diet. Think "baby food". Do not consume more than ½ cup of food during any single meal, and stop eating and drinking before that amount if you start feeling full or uncomfortable. After surgery, patients should only consider moving to a subsequent diet stage if they are tolerating their current diet stage without any problems.
