So no matter how much protein or fat you eat, the body still has to break down fat to ketone bodies to keep you going.Ī ketogenic diet, then, is any diet that switches your metabolism to ketosis. Once the body has no source of glucose, it has to switch to ketosis because the brain needs either glucose or ketone bodies to survive. All you need to do is remove carbohydrate from the diet (not just refined carbs, such as sucrose or high fructose corn syrup, but all carbs, including complex carbs and starches too). On the other hand, not eating for days doesn't sound much fun.īut it turns out you don't need to starve yourself to get into ketosis. ![]() ![]() Being in ketosis, then, does sound like a great way to burn off the fat. Our metabolism then switches to fat-burning, and converts stored fat molecules into ketone bodies that can power our muscles and brain because the glucose has run out. Normally, we only enter ketosis (where ketone bodies accumulate in the blood) when we starve ourselves – not just overnight or by missing a meal, but for several days at time. Bizarrely named “ketone bodies” are actually molecules that act as the body’s natural back-up fuel supply when glucose is scarce. ![]()
