As a clinician, I believe everyone on the planet would benefit from a cyclic ketogenic diet. This means that the body uses ketone bodies as its primary fuel source a majority of the time. To get into and maintain ketosis you eat a low-carb diet with only moderate amounts of protein and high amounts of good fats.
There is a growing segment of the natural health movement that endorses the ketogenic diet as the best nutritional approach. The biggest challenge people have is navigating how to set up meals to maintain ketosis.
When meal planning on a ketogenic diet you will take into account your unique metabolism. Some people do great with intermittent fasting where they go 16-18 hours without a calorie source. Other individuals who have adrenal fatigue may need to eat every 4 hours or so to maintain stable blood sugar and elevate ketones appropriately.
In my online course, Navigating the Ketogenic Diet, I go over EXACTLY how to set this up with my E-books, 30-day meal planner, video guides, video recipes, etc. Check it out at the link below.
