Ketogenic diet (keto diet).
It’s a low-carb, high-fat diet which encourages the body to burn fats instead of carbohydrates.
It might not work if you don’t get the food proportions right. The person may not cut enough carbs out of their diet (they won’t lose weight).
It also doesn’t work for everyone (There is some explanation behind it but I don’t know it, sorry. However, you could say that just like other diets, it just doesn’t work for some people and their metabolism).
