There are new discoveries linking ketogenic diet to an amazing range of positive effects on health coming out of the research lab every day. Ketone bodies, the by-products of eating high fat and low carb diet, have especially interesting properties.
The journal Cell Metabolism published an interesting study, done on mice. By feeding them ketogenic chow they realized that mice have a better memory and the mortality rate before old age decreases.
The mice were assigned to three different diets: the control group got the “normal” food (75% carbs, 15% protein and 15% fats), the ketogenic group had a diet with a complete carb-restriction (10% protein and the rest comprised of fats) and the high-fat group was fed 15% carbs, 10% protein and 75% fats, whereby no ketosis was induced.
At one year of age (which translates to middle age for mice) they tested their memory and repeated that in the older age at around two years old. The group on the ketogenic diet was the only one who performed equally as good in the old age as compared to middle age. They were energetic and had decreased mortality before the old age. In this experiment the mice on the high-fat no-ketosis diet performed the worst: their life-span was the shortest (Newman et al., 2017).
