The ketogenic (keto) diet is a high-fat, low-carbohydrate eating plan designed to shift the body into a state of ketosis, where it burns fat for fuel instead of glucose.
Typically, it involves consuming 70-75% fat, 20-25% protein, and 5-10% carbs. By drastically reducing carb intake, the body produces ketones from fat, which serve as an alternative energy source. Common foods include meat, fish, eggs, nuts, seeds, avocados, and low-carb vegetables.
The diet is popular for weight loss, improved mental clarity, and managing conditions like epilepsy or type 2 diabetes. However, it may cause side effects like the “keto flu” during adaptation.
