Following a ketogenic diet may lower your blood sugar. But experts don’t know whether this diet is any better at lowering blood sugar than other diets. The amount of weight you lose may be more important than the specific diet you follow. A ketogenic diet is a high-fat, low-carbohydrate diet where most of the calories you eat come from fat.
Studies show that this diet may lower your blood sugar in the short-term. You may lose weight on this diet, too. Weight loss is also known to lower blood sugar. Experts don’t know yet if the reduced blood sugar is from the diet or the weight loss. Either way, lowering your blood sugar is an important goal.
The long-term effects of a ketogenic diet are unclear. Talk to your doctor about ways you can manage your blood sugar.
