The Truth About the Keto Diet: Does Science Support It?

The video explores the keto diet, a high-fat, low-carb diet, tracing its historical roots and scientific studies. It discusses the diet's effects on weight loss, brain health, and athletic performance, while highlighting its role in managing epilepsy. The mechanism of ketosis, where the body uses fat for energy instead of glucose, is explained. The video also examines the diet's neurological benefits and challenges the carbohydrate-insulin hypothesis for weight loss.
