The ketogenic diet is a very successful weight-loss program. It utilizes high fat and low carbohydrate ingredients in order to burn fat instead of glucose. Many people are familiar with the Atkins diet, but the keto plan restricts carbs even more. Because we are surrounded by fast food restaurants and processed meals, it can be a challenge to avoid carb-rich foods, but proper planning can help. Plan menus and snacks at least a week ahead of time, so you aren't caught with only high carb meal choices.
