Proper Diet Following Bariatric Surgery

Bariatric surgery is a weight-loss surgery that is meant for obese individuals who have failed to lose weight by traditional methods. Individuals with a body mass index greater than 40 or those with a body mass index greater than 35, with obesity-related diseases can be eligible for bariatric surgery. Common procedures include the adjustable gastric band, the Roux-en-Y gastric bypass and vertical sleeve gastrectomy. Significant results depend on a proper diet and physical activity following the surgery.

Full Liquids

A full liquid diet should be followed for three weeks following surgery. Each hour, drink 1/4 cup of a high-protein liquid nutrition supplement. Then, every 15 minutes, you should drink a non-carbonated, non-caffeinated beverage, such as water or juice mixed with water. The high-protein supplements are necessary to maintain lean muscle mass. Examples of protein supplements acceptable during the full-liquid phase of the diet include Ensure or Boost.

Soft Foods

Soft foods are then introduced for the next six to eight weeks post-surgery. Eat foods high in protein, while avoiding foods that are high in fiber, sugar and fat. Eat four to six times per day. Eat the protein foods on your plate first. Suggested foods include tuna, eggs, yogurt, ground meats, oatmeal, well-cooked vegetables and canned fruits. Add one food at a time to your diet to make sure you can tolerate it.

Solid Foods

Solid foods can be introduced back into your diet 10 to 12 weeks post-surgery. Maintaining a well-balanced diet is important in this stage. Your diet should include lean protein, fruits, vegetables and low-fat dairy products. You will still need to avoid foods high in fat and sugar. Make sure to eat at least 3 oz. lean protein at each meal. Because the amount of food you can eat at each meal is limited, choose wisely. Eat nutrient-dense foods.

Tips

Avoid liquids before and during meals, but make sure to drink enough fluids between your meals to prevent dehydration. Chew thoroughly and eat slowly. Pay attention to whether you are full. If you continue to eat once you are full, vomiting may result.
