The Management of Very Low-Calorie Ketogenic Diet in Obesity Outpatient Clinic: A Practical Guide

In the 2019 review, the authors provided a guide for managing obesity with a very low-calorie ketogenic diet (VLCKD) in an outpatient setting. VLCKD, which is high in fat and very low in carbohydrates and protein, has been effective for rapid weight loss and improving metabolic profiles. The diet protocol includes stages for calorie restriction, food reintroduction, and maintenance. It is recommended for individuals with severe obesity and has specific indications and contraindications. Side effects such as dehydration, hypoglycemia, and gastrointestinal issues are common, but manageable with proper monitoring and nutrient intake. The review also addresses the prevention of potential risks like kidney stones, gallstones, and hair loss, recommending strategies such as adequate fluid intake and increased protein during fasting. The VLCKD is highlighted as an effective tool for those needing rapid weight loss and emphasizes the importance of a healthy lifestyle for long-term maintenance.
