Ketogenic diets produce superior short-term glycemic control (HbA1c reduction) compared to low-carbohydrate diets, but are not superior to other dietary patterns for long-term weight loss or metabolic outcomes.

If you have Type 2 Diabetes, a strict ketogenic diet (20-50g carbs/day) can lower your HbA1c faster than standard low-carb diets in the short term. However, do not expect it to help you lose more weight in the long run compared to other healthy diets. It is a tool for glycemic control, not a magic bullet for weight loss.
