The Standard Ketogenic Diet appears to be the most researched particularly with regard to its ability to help people lose weight and control blood sugar. It typically comprises 70-75% fat, 20% protein and 5-10% carbs. When following a ketogenic diet be sure to include plenty of non-starchy vegetables, like kale and spinach which are very low in carbohydrate. Under normal circumstances our body uses glucose from carbohydrate foods for energy. In the absence of glucose a process called ketosis occurs.
