The ketogenic diet (keto for short) is a highly popular diet plan because it delivers significant weight loss results for avid followers. Not only can people meet their weight loss goals, but they also report improved energy levels, better satiety after meals, and more control over their blood glucose levels and cholesterol.
The ketogenic diet is a high fat, low carbohydrate diet. while eating a diet high in fat seems counterintuitive for weight loss, the keto diet delivers results because it forces your body into ketosis. By severely restricting carbohydrates, your body does not have access to glucose (sugar) from your diet, so It must turn to stored energy sources in your body. Ketosis is the state where your body burns stored fat for energy as opposed to using glucose. When you are in ketosis, your liver converts fat into ketones, which can then serve as energy to fuel our bodies. By using our stored fat for energy as opposed to carbohydrates, we can burn fat and lose excess weight.
Because the keto diet is known for helping people lose a significant amount of weight, many people who undergo bariatric surgery wonder if this diet is safe after surgery. The answer is yes, and no.
If you follow the keto diet strictly without making subtle modifications, it is not safe for people who have had bariatric surgery. The reason for this is two-fold. Firstly, the keto diet is not high in protein, which is necessary for people who have bariatric surgery. Secondly, the diet is high in fat content, which can be problematic for bariatric surgery patients struggling with fat digestion and absorption. Unless a bariatric surgery patient modifies a keto diet, they may be at risk for nutritional deficiencies.
A ketogenic diet can be safe and effective in helping post-bariatric surgery patients lose weight if you follow a modified diet. Therefore, post-bariatric surgery patients should eat a ketogenic diet that is high in healthy fats, high In protein, and low In carbohydrates. A modified ketogenic diet would be an option for bariatric patients who hit a plateau after actively losing weight post-surgery, usually around 18 months after surgery. Or for those who start regaining weight years after surgery. Health care professionals still need to follow routine nutritional parameters specific to the type of surgery.
