A very low-calorie ketogenic (VLCK) diet (under 50g carbohydrates, 600-800 kcal) is safe and effective for short-term weight loss and glycemic control in type 2 diabetes patients, without causing renal deterioration despite high protein intake.
For a Type 2 Diabetic with obesity, a short-term (4-month) very low-calorie ketogenic diet (under 50g carbs, 600-800 calories) is a safe and highly effective way to lose weight and improve blood sugar control, provided you do not have advanced kidney disease. It is more effective than standard low-calorie diets and does not harm kidney function in the short term. Expect mild side effects like fatigue or headache initially, which usually subside.
The interventional weight loss program based on a VLCK diet is most effective in reducing body weight and improvement of glycemic control than a standard hypocaloric diet with safety and good tolerance for T2DM patients.
Why this rating
Randomized clinical trial, but short duration (4 months) and potential conflict of interest (industry funding).
