Protein intake is vital after bariatric surgery. A limited stomach capacity requires eating protein first and fulfilling your daily nutritional expectations. Your target is to exceed 60 to 90 grams of protein each day. Eating high-protein food sources, including chicken, fish, eggs, or beans, can meet this goal.

Why is protein important after bariatric surgery?

Protein is essential to promote healing and prevent the loss of lean muscle mass. It also reduces potential side effects like hair loss, bone density loss, and saggy excess skin. Protein is an incredibly powerful source of energy and must be eaten first during every meal.

Best Food Sources of Protein

Eating high-protein food is the best way to meet minimum protein requirements. Here are some good high-protein sources

  1. Eggs: can be scrambled for breakfast or hardboiled to add to salads or have for snacks.
  2. Meat and Poultry: lean meats are good options to add to salads or to have as a side with steamed vegetables.
  3. Seafood: Tuna is a convenient choice to add to salads or to have as a side for any meal.
  4. Beans, Lentils, and Chickpeas: can be added as a side, into a soup, or as hummus to increase protein intake after surgery.
  5. Tofu: a great way to add protein to a plant-based diet. It can be scrambled for breakfast or creamed as a dip for a snack.
  6. Dairy: yogurt, cottage cheese, and milk add protein and calcium to your diet. Read this if you’re lactose intolerant.
  7. Nuts and seeds: can be added to yogurt, salads, or bariatric smoothies to increase protein intake.

What to look for in a protein supplement?

Any protein supplement you take should be a source of complete protein. A complete protein has nine essential amino acids; histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Protein after bariatric surgery

We recommend protein supplements containing at least 20 grams and less than 5 grams of sugar.

Collagen supplements are not complete protein sources and shouldn’t be taken instead of protein supplements.

Final Notes

Protein is derived from the Greek word “proteious,” meaning “of prime importance.” Protein is part of every cell in our body. The human body does not store protein, as it does fat and carbohydrate. Therefore, it needs to be replenished daily by the food we eat.

Eating enough high-quality protein boosts your metabolism, keeps you fuller for a longer period of time, and helps your body burn fat instead of muscle for healthier weight loss.
