VLCD vs Keto Diet
The Very Low Calorie Diet (VLCD) is often used before weight loss surgery to shrink the liver, this allows it to be retracted far away from the stomach and helps prevent surgical complications. The VLCD can last from anywhere between 2-6 weeks prior to surgery. A patient’s starting BMI and liver size on ultrasound will guide the surgeon’s recommendation as to how long this period lasts. The VLCD is less than 800 kcal/day and makes use of shakes, bars and soups along with vegetables, salads and plenty of water.
