Bariatric Surgery Diet: What Foods to Eat After Surgery



Your doctor may have told you that bariatric surgery alone isn’t enough to help you lose weight. You’ll also need to make some lifestyle changes, starting with the way you eat.

Weight loss surgery can help you to curb your appetite and reduce your calorie intake. However, it’s up to you to ensure you’re filling up on the right foods to propel you toward your goals.

Stock up on these best foods to eat after weight loss surgery to keep the right nutrition within arm’s reach at all times:


Protein Powder

Right after weight loss surgery, your doctor will likely put you on a liquid diet for a few days. Protein powder packs a lot of essential nutrients in a quick and easy shake. Look for a protein powder with at least 15g of protein and half as many carbs (or less).


Peanut Butter

Peanut butter is an excellent source of protein. Just a little spoonful can be filling and help to curb cravings.



Flaxseed is nearly tasteless on food but adds essential nutrients like fiber, omega-3’s, and protein. Add it to your protein shakes or sprinkle some on your food.



Packed with vitamins, fruits can be a healthy snack or side dish. Try to choose fruits low on the glycemic index, such as grapes, apples, or grapefruit.


Vegetable Juice

All-natural veggie juice can help you get your daily servings of vegetables, even when you’re on a liquid diet. If you can’t stand the taste, V-8 offers a blend of fruit and veggie juices that’s sweet and satisfying.



Applesauce is a step up from the liquid diet and gives you all the benefits of fruit. Individual packs are just big enough for a snack and keep you from overeating.


Low Sodium Soups

Chicken noodle, tomato, vegetable, lentil - there’s a soup to suit every taste. Opt for low sodium soups to cut calories - you won’t be able to taste the difference, but will do your health a favor.


Canned Veggies

Quick and easy to prepare, a can of vegetables can be a meal in itself or complement the main course. They’re loaded with nutrients so you can feel good with every bite you take.



Rich in fiber and antioxidants, oatmeal offers a tasty, satisfying meal. You can dress it up with fruit, or just add flax seed to increase its nutrition.


Nonfat, Sugar-Free Yogurt

Yogurt will be one of the best ways to balance your diet before you can eat solid foods again. They’re chock full of probiotics to help you nurture your gut. Opt for yogurt with low fat and sugar content, ideally 150 calories or fewer.


Almond Milk

An excellent alternative to skim milk, almond milk offers all the nutritional benefits of regular milk without the fat and calories. Use it to make your protein shakes, pour it over your cereal, or enjoy a glass by itself.


Change Starts One Food at a Time

Changing the way you’ve always eaten isn’t easy, but it will be essential to a successful weight loss surgery. Take it one step at a time, starting with the foods you eat on a daily basis. Once you find foods you love, it’s easier to form better eating habits that will stick with you for life.
