Commercially available very low-calorie diets (VLCDs) with intensive behavioral support produce significantly greater weight loss and cardiovascular risk improvement than low-carbohydrate/high-protein (LCHP) diets in obese patients who fail to respond to standard low-fat diets.
If you have a BMI over 35 and standard dieting hasn't worked, a medically supervised very low-calorie diet (VLCD) combined with weekly group support is significantly more effective for weight loss than a low-carb diet. The key to success is not just the low calories, but the structured support and counseling provided by the program. Expect to lose significant weight (over 15kg on average in this study) if you stick with the program for 9 months.
Significantly greater weight loss was seen for patients on the LL than the LCHP at 3 (mean (±SD) )11.6 ± 12.9 vs )2.8 ± 4.5 kg, respectively; P < 0.0001) and 9 months ()15.1 ± 21.1 vs )1.9 ± 5.0 kg, respectively; P < 0.0001) after screening.
Why this rating
Randomized controlled trial with intention-to-treat analysis, though attrition was high and baseline characteristics differed.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
