The Keto Diet: Is it a Good Fit for Bariatric Surgery Patients?
The keto diet has gained popularity in the past few years in New Jersey and beyond, especially on social media. I often get asked whether or not the keto diet is right for bariatric surgery patients. The short answer is no - the keto diet, also known as the Ketogenic Diet, is not generally recommended for people who had bariatric surgery and here’s why.Â
What is the Keto diet
Following a ketogenic diet means fats are the main source of food. The keto diet is high in fat, moderate in protein and low in carbohydrates. Keto forces the body to burn fat instead of carbohydrates for energy. The amount of fat consumed is not usually limited and typically makes up about 70-80% of daily calories. This leaves only 20-30% of your daily calories coming from carbohydrates AND protein.Â

Nutrition Needs After Bariatric Surgery
Following a bariatric diet requires 60 - 100 grams of protein per day. However, the keto diet limits protein intake and fiber-rich foods. After bariatric surgery, lean protein should make up the majority of the post-operative diet in order to minimize loss of muscle tissue during times of active weight loss. Also important are fiber-rich foods which help prevent constipation and increase fullness.
Why Keto is Not Recommended For Bariatric Patients
The development of fatty diarrhea, nutrient malabsorption and dumping syndrome are potential downsides of the keto diet following weight loss surgery. This significant decrease in protein and fiber-rich foods is why we do not recommend the keto diet for patients who had bariatric surgery.
