Recently, many of my patients have been asking about a ketogenic diet. Is a ketogenic diet safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost years to treat drug-resistant epilepsy, especially in children. In the s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss. In essence, it is a diet that causes the body to release ketones into the bloodstream. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies the process is called ketosis. Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day.
A ketogenic diet restricts carbohydrate intake to less than 25 to 50 grams per day in an attempt to enhance tissues to use fat or ketones acids produced by the liver as fuel during caloric restriction. Ketogenic diets were first used in the s to treat diabetes prior to the discovery of insulin. These diets were also used to treat difficult-to-control epilepsy in children. Recently, ketogenic diets have been promoted as weight-loss diets and to control blood glucose in patients with prediabetes and type 2 diabetes. Keto diets may lead to weight loss in the short term, but that weight loss is similar to what is achieved with other dietary approaches over the long term. Keto diets may improve blood glucose in the short term in patients with type 2 diabetes, but there is inconclusive scientific evidence that these diets are superior to other weight-loss regimens in the long term. Claims of benefits of the ketogenic diet for cancer, dementia, and Parkinson disease are not scientifically substantiated. Most fruits, legumes, and whole grains are also essentially off limit. Currently, long-term data on keto diets and cardiovascular, cancer, and other chronic disease risks are lacking, and low-carbohydrate diets have been linked to increased mortality. Individuals wishing to lose weight using a very structured approach may benefit from a keto diet.
