Long-term health risks from the ketogenic diet

"No one should be doing the ketogenic diet," says top U.S. cardiologist

The ketogenic diet is one of the latest dietary fads to sweep the U.S., promising rapid weight loss, enhanced brain function and sustained energy throughout the day. These effects are achieved by replacing high-carb foods with fatty, protein-rich foods, which will eventually put the body in ketosis: a natural metabolic state in which the body burns fat for fuel instead of carbohydrates.

According to Dr. Kim Williams, former president of the American College of Cardiology, no one should adopt the ketogenic diet over the long term—unless weight loss is more important than lifespan.
