Is Intermittent Fasting Safe After Bariatric Surgery?

Back to Blog


Bariatric surgery in Mexico is meant to help you lose a significant portion of your body mass. If you are like most patients, you want to do everything you can to enhance and speed up the results—and the first place you’ll be able to make changes is in your post-op diet.

Intermittent fasting has recently become quite trendy in the world of diet and nutrition, with many swearing it is the single best approach to diet if you want to cause weight loss. But is intermittent fasting safe after bariatric surgery?

First, Let’s Talk Intermittent Fasting

Typically, diets focus on altering your meal plan. Eat fewer calories, consume less from this food category, increase your consumption of this one, and so on. Intermittent fasting is about altering your eating patterns.

Specifically, it is about restricted all eating to a shorter portion of the day. For example, one of the most popular intermittent fasting schedules is 16:8. With this approach, you fast for 16 consecutive hours each day, then allow yourself to eat your meals in the remaining 8. Since part of that fasting takes place during sleep, there are usually just a few hours at night and then again in the morning where the individual cannot eat or drink anything except water.

Does Intermittent Fasting Work?

This is a big debate in the medical and wellness community. Some say that when insulin raises after eating, it prevents fat burn. By increasing the time between meals, you leave insulin levels lower for longer, maximizing fat burn.

However, others insist that intermittent fasting does nothing special. Weight loss from fasting is just due to a decrease in consumption; when you have less time to eat, you eat less.

Intermittent Fasting After Bariatric Surgery

Should you fast after bariatric surgery? This hasn’t been well researched, so any answer you get about this should be taken with a grain of salt. We think that you should consider the following points when making your decision:

  • Intermittent fasting can help reduce overall calorie consumption, but it can also make you feel pushed to eat larger portions at each meal, which is very bad after bariatric procedures.
  • In theory, fasting causes the body to attack fat stores, not muscle, helping guide you towards healthier weight loss.
  • Early in your post-surgery recovery, you may need to consume nutrients throughout the day to heal, making fasting a bad choice at that time.
