Ketogenic, or keto, diets are low-carb and fat-rich, and many people who follow such regimens do it to shed excess weight. However, a keto diet may bring other benefits, too. In particular, it may help keep the brain healthy and young, as new research in mice seems to suggest.
A keto diet is high in fat, low in carbohydrates, and has an adequate amount of protein.
This kind of diet is meant to trigger ketosis, which is a metabolic process through which the body breaks down fat and protein and transforms them into energy, leading to weight loss.
