12 Diets That Have Worked and Stood the Test of Time

3.      Ketogenic Diet

The aim of this diet is to lower levels of insulin by shifting the body’s primary fuel source from sugar to ketones. In the absence of glucose, the body starts to burn fat as its alternate energy source.

This diet starts off with and maintains carb control throughout. You don’t get to reintroduce carbs in a big way as the diet progresses. Instead the ketogenic diet restricts carb consumption to less than 30 grams daily.
