A Very Low-Calorie Ketogenic Diet (VLCKD) is a safe and effective intervention for weight loss and metabolic improvement in patients with obesity and mild chronic kidney disease (Stage 2 CKD), without causing clinically relevant renal deterioration.

If you have obesity and mild kidney issues (Stage 2), a medically supervised VLCKD (450-800 calories, <20g carbs) is a safe and effective way to lose significant weight (~20%) without harming your kidneys. Ensure you take supplements and drink plenty of water.

We conclude that, when conducted under the supervision of healthcare professionals, a VLCKD is an effective and safe treatment for weight loss in patients with obesity, including those affected by mild kidney failure.
