The ketogenic diet is a high-fat, low-carbohydrate eating plan designed to shift the body's metabolism from burning carbohydrates to burning fats for energy. 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 fuel. Typically, the diet consists of foods like meat, fish, eggs, dairy, nuts, seeds, and low-carb vegetables, while avoiding sugary foods, grains, and starchy vegetables. This approach may help with weight loss and has been studied for its potential benefits in managing certain medical conditions, such as epilepsy and type 2 diabetes.
