Sustainable weight loss is a long-term journey requiring significant changes in eating habits, commitment to a regular exercise program, a tool like bariatric surgery, and the assistance of a dedicated support network. This is a journey that should begin now: the minute you decide to commit yourself to achieving your weight loss goals. Board Certified surgeon Dr. Wiljon Beltre and his experienced staff at The Center for Metabolic and Obesity Surgery in Altamonte, Florida, want to make your weight loss surgery and the journey that follows as safe and effective as possible, in order to give you the greatest possible chance of success. We have prepared this pre-surgery guide to facilitate that success, and are eager to work with you at each and every step—before, during, and after your procedure—and stand together with you on the path to finally realizing true, long-term weight loss!


Once you have committed to weight loss surgery, it is critical to begin losing weight immediately by starting a low-fat, high-protein, well-balanced diet. The dietary instructions you will receive are specifically designed to reduce the amount of fat cells in the liver and around the intestines. If the liver contains too much excess fat, it may crack and begin bleeding as it is moved away from the stomach during surgery. Moreover, large amounts of fatty tissue around the intestines make working with the intestines extremely difficult, potentially leading to injury, leaks, or other complications. Thus, committing to a weight loss diet in advance will help ensure that your surgery is quicker and safer, and your recovery time shorter. The dietary guidelines for patients preparing for bariatric surgery include:

  • Protein supplements and/or protein powder
  • Healthy foods like yogurt, oatmeal, eggs, lean meats or fish, fruits, vegetables, and whole grains
  • Limit fats from the diet, including fatty meats, fried foods, and whole dairy products
  • Limit foods high in refined carbohydrates such as bread, pasta, cakes, and cookies
  • Limit sweets and sugary foods, including regular soda
  • Avoid alcoholic beverages
  • Stop any over the counter herbal supplements

In addition to dietary changes, you will need to begin certain lifestyle changes that will continue after your surgery. While every form of weight loss surgery will have its own specific lifestyle and dietary requirements, there are a few changes that should develop into lifetime habits for all patients:

  • Stop smoking
  • Avoid binge eating
  • Stop all carbonated beverages and beverages containing caffeine
  • Begin the practice of not drinking with your meals. Start drinking 30 minutes before you eat and do not drink again until 30 minutes after your eat
  • Begin a routine exercise program (consult your physician first)
  • Begin cutting food into small pieces and practice chewing very well
  • Join a monthly support group


Two Weeks before Surgery: You will begin a high protein diet, consisting of a protein shake (low in sugar and carbohydrates) for breakfast and lunch, followed by lean meat and vegetables for dinner. Protein shake mixtures may be purchased from your local grocery store or retail stores such as GNC, Wal-Mart, or Target. You may drink sugar-free liquids between meals.

One Week before Surgery: Stop taking Coumadin, Plavix, Aspirin, Ibuprofen or other arthritis medications because these medications can cause stomach irritation and/or more bleeding after surgery. Have your physician convert all of your time released or extended released medication to non-time released. If you are unsure about which medications to stop, contact your pharmacist.

Two days before surgery: Begin Clear Liquid Diet: YOU MUST NOT EAT ANY SOLID FOOD DURING THE TWO DAYS LEADING UP TO YOUR SURGERY. You will need to consume ONLY clear liquids such as apple or other clear juice (juice without pulp),clear broth (chicken, vegetable, or beef), Jell-O (any color is fine), popsicles, water or flavored water products.

Morning of Surgery: You must stop taking Metformin or Pradaxa the day before surgery. The night prior to your procedure, you will receive a call from the hospital to be told when to report to the hospital. Please remember to bring a picture ID and/or driver’s license with you to the hospital, because we will need to verify your identification before admitting you. If you consumed any medication the morning prior to reporting to the hospital, let the nurse know. Once you are checked in, you will be asked to remove all of your clothing and put on a patient gown and a pair of booties. The nurse will start an IV in preparation for surgery, and you will begin to receive medications that have been ordered by your physician or anesthesia. You will be then be taken to the operating room and placed in the holding area to meet the individuals who will be taking care of you during surgery. The anesthesiologists will speak to you as well, and you will be given some medication that will relax you prior to actually being taken to the Operating Room suite. Your family members will be asked to wait in the Surgical Waiting Room.

Preparing for surgery can be challenging both physically and mentally, but Dr. Beltre, the weight loss professionals at The Center for Metabolic and Obesity Surgery, and the hospital staff are committed to assisting you through the entire process. We encourage you to ask questions and vocalize your concerns at any time so that we can address them quickly and thoroughly and make you and your family are as comfortable as possible as you begin this exciting and life-altering journey!
