The ketogenic diet is a high-fat, moderate protein, low-carb diet.
It's a diet that causes ketones to be produced by the liver, shifting the body's metabolism away from glucose and towards fat utilization.
Ketogenic diets emphasize foods rich in natural fat and adequate in protein, and restrict foods high in carbohydrates (sugars and starches).
The term “ketogenic” refers to the fact that when the body metabolizes fat for fuel, ketone bodies are created through a process called ketogenesis. When there are elevated levels of ketone bodies in the blood, one is said to “be in ketosis.” As ketone levels in the blood rise, our cells can begin using them for fuel.
The ketogenic diet is an effective weight loss tool and has been shown to improve several health conditions such Alzheimer's, Parkinson's, epilepsy and even cancer. Healthy cells can use ketones for energy, but cancer cells cannot and they literally starve to death.
