Under normal circumstances our body uses glucose from carbohydrate foods for energy. In the absence of glucose, a process called ketosis occurs. This is a state in which the body burns fats instead of carbohydrates as its main fuel source. When we don’t eat carbs, the liver breaks down fat stores to produce energy.

Ketogenic diets were originally developed to treat epilepsy in children as it appears to reduce the frequency of seizures. What foods are allowed on a ketogenic diet? Foods that are generally allowed include high-fat meats, fish, oils, nuts, high-fat dairy such as cheese, and low-carb vegetables such as leafy greens. Unsurprisingly, reducing carb levels means cutting out bread, pasta, rice, and most conventional baked goods. However, achieving such low levels of carbs also means skipping legumes, root vegetables, most fruits and starchy veggies, such as potatoes.
