Beyond Weight Loss A Review Of The Therapeutic Uses Of Very Low Carbohydrate (ketogenic) Diets

This comprehensive review examines how very-low-carbohydrate ketogenic diets—which limit carbs to less than 50 grams per day while increasing protein and fat—may offer therapeutic benefits for multiple health conditions. While most people know ketogenic diets for weight loss (popularized as the Atkins Diet), researchers have been studying their medical applications since the 1920s, when they were first used successfully to treat epilepsy.

The review presents evidence that ketogenic diets may help manage a surprising range of conditions including type 2 diabetes, polycystic ovary syndrome (PCOS), acne, various neurological diseases, and even cancer. The diet appears to also improve cardiovascular and respiratory disease risk factors. When the body enters ketosis—a metabolic state where it burns fat for fuel instead of carbohydrates—it triggers various biological changes that may explain these wide-ranging health benefits.

What makes this research particularly compelling is the potential to reduce dependence on pharmaceutical treatments, which often require lifelong use and can cause significant side effects. Given that pharmaceutical costs exceed $750 billion annually in the US, nutritional interventions that can replace or reduce medication needs could provide both health and economic benefits.

For clinical practice, this research suggests that ketogenic diets deserve serious consideration as therapeutic tools beyond weight management. However, patients should work closely with healthcare providers experienced in ketogenic approaches, as these diets require careful monitoring and may not be appropriate for everyone, especially those with certain medical conditions or taking specific medications.
