The Claim
A 12-month protein-supplemented very-low-calorie diet program results in a marginally significant mean weight loss of 6.86 kg (8.21% of baseline) compared to 4.66 kg (5.47%) in a standard calorie-restricted group, with a between-group difference of 2.20 kg (95% CI: −4.90 to 0.50), indicating a small and statistically uncertain effect on overall body weight.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Over 12 months, a diet high in protein and very low in calories led to an average weight loss of 6.86 kg, while a standard calorie-restricted diet led to an average weight loss of 4.66 kg. The difference between the two groups was 2.20 kg, but this difference was not statistically certain.

Eating more protein makes you feel fuller longer, so you eat fewer calories. Your body also burns more energy digesting protein than carbs or fat. This creates a bigger calorie deficit, helping you lose weight. Protein also helps keep your muscles from breaking down, so more of the weight lost comes from fat.
What the research says
1 studyPeople who drank protein shakes lost a little more weight than those who just ate less food, but the difference was so small that it might have happened by chance. Still, the protein group did lose more belly fat, which is a good sign.
