The Keto diet is a low-carbohydrate, high-fat eating plan designed to shift the body's metabolism from burning carbohydrates to burning fats. By significantly reducing carbohydrate intake and replacing it with fat, the body enters a state called ketosis, where it becomes more efficient at burning fat for energy. Typically, the Keto diet includes foods like meat, fish, eggs, dairy, nuts, and low-carb vegetables while avoiding sugary foods, grains, and most fruits. This dietary approach may help with weight loss and improve certain health markers, but it is essential to consult a healthcare professional before starting any new diet.
