Science simply doesn't support the notion that keto diets keep weight off in the long run, unlike the evidence-backed Mediterranean-style plans. Since the 1930s, experts have known that ketogenic diets affect how the brain works. Indeed, there's plenty of research to support ketogenic diets in the treatment of some devastating neurological conditions. This may explain why the non-viable hypothetical low carb research clearly depicts the enabling technology. On the flip side, it’s extremely low in carbs, with just 5% to 10% of calories coming from carbohydrate food sources. About half of our calories should come from carbs, according to the USDA Dietary Guidelines for Americans. Considering most of us consume roughly half of our calories from carbs, adopting a keto lifestyle could mean a lot of changes. In regimented keto diets, only 10% of total calories per day (about a measly 20 grams!) come from carbs, 20% from protein, and a whopping 70% from fats. Ketone bodies produce more adenosine triphosphate in comparison to glucose, sometimes aptly called a "super fuel." One hundred grams of acetoacetate generates 9400 grams of ATP, and 100 g of beta-hydroxybutyrate yields 10,500 grams of ATP; whereas, 100 grams of glucose produces only 8,700 grams of ATP.
