Restarting weight loss after gastric bypass surgery can be tricky. Going back to the basics and starting over can be intimidating. However, if you stay consistent and work hard, you can get back on track and lose the extra weight you may have gained back.

In this guide, we’ll put you on the right path to break the weight loss stall after gastric bypass.

What This Article Covers:

What Is a Gastric Bypass?

Gastric bypass is a common bariatric procedure that involves making the stomach smaller and changing how the small intestine handles and absorbs food. In other words, the procedure “forces” the patient to feel full quickly resulting in weight loss.

In some severe cases of obesity, usually a BMI of 35 to 40 and over, the excess weight may threaten quality of life and increase the risk of severe health conditions. In that case, the doctor may recommend gastric bypass surgery to shed off excess weight.

The duration of a gastric bypass procedure is typically around 1-3 hours.

What Is a Bariatric Pouch Reset?

When you undergo a gastric bypass procedure, the stomach is made into a very small pouch. The "new stomach pouch" will tell you when your full, even after a small amount of food is consumed. When you feel pressure, this is the signal to stop eating. When you continuously overeat, the stomach has to stretch in order to accommodate food.

A bariatric pouch reset is a diet that brings you back to the basics of eating after bariatric surgery. It doesn't necessarily shrink your stomach back to a normal size, but instead, helps you to get back on track mentally and lose some weight.

We are all human and old eating habits can resurface. This diet gives you the ability to get back to the basics and maintain your healthy lifestyle. This diet is usually done several months or years after surgery.

How to Do a Bariatric Pouch Reset

A bariatric pouch reset diet is more or less the same as your post-surgery diet that lasted for 8-10 weeks. Luckily, the reset is typically only 1-2 weeks. However, since you’ll be drastically limiting your food intake, it’s crucial that you follow up with a surgeon and a registered dietitian during a bariatric pouch reset.

In many cases, your dietitian will recommend additional supplements to compensate for any micronutrient deficiencies during the duration of the diet, such as chewable multivitamins, corrective supplements and protein powders.

Continue to choose healthy food options and follow portion sizes. Excessive intake of any food, even healthy options, can still cause weight gain. Here are some tips to keep in mind during this period:

  • Follow up with your surgeon and dietitian on a regular basis
  • Track intake
  • Eat protein first, then non-starchy vegetables, fruits, and carbohydrates (whole grains) last
  • Chew slowly, it should take you 25-30 minutes to eat
  • Avoid drinking liquids 30 minutes before and after meals

*Each Registered Dietitian will have different recommendations based on the surgery center they work in.


When all is said and done, restarting weight loss after gastric bypass is definitely achievable, provided that you maintain the lifestyle change that we’ve talked about in this article.

Remember, a gastric bypass journey requires consistent effort if you want to maintain the results of surgery.
