The authors believe it is plausible that the use of a ketogenic diet for a limited period of time would produce a sustainable regression of the underlying conditions associated with diabetes, significantly resetting gene expression profile With regard to macronutrients, the difference between these diets depends on the percentage of residual calories from fats hypo, normal or hyper lipids and proteins.

Timerestricted feeding without reducing caloric intake prevents metabolic diseases in mice fed a high-fat diet.

For example, in one study of a ketogenic diet for type 2 diabetes, researchers encouraged unlimited meat, poultry, seafood, and eggs, while cutting olss of whole grains, fruits, and starchy vegetables and limiting intake of salad vegetables and non-starchy vegetables This depletion of carbohydrates places the body in a state called ketosis, a metabolic state characterized by a lack of glucose in the body.
