The keto diet, short for ketogenic diet, is a low-carbohydrate, high-fat eating approach. By significantly reducing carb intake and replacing it with fats, the body enters a state of ketosis, where it burns fat for energy. This metabolic shift can lead to weight loss, stabilized blood sugar levels, and potential benefits for mental clarity and overall health. However, individual responses vary, and consultation with a healthcare professional is recommended before adopting a keto diet.
