The Claim
In severely obese adolescents aged 12–18 with BMI ≥27 kg/m² who failed conventional weight loss methods, a 6-month protein-sparing modified fast (PSMF) under medical supervision was associated with an average weight loss of 11.19 kg (9.8% of baseline weight) in those completing follow-up, with 50% achieving >5% weight loss and 20% achieving >10% weight loss.
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.
Among severely obese adolescents aged 12 to 18 with BMI of at least 27 kg/m² who did not lose weight through standard methods, a medically supervised 6-month protein-sparing modified fast resulted in an average weight loss of 11.19 kg, with half losing more than 5% of their starting weight and one-fifth losing more than 10%.

When carbs and fats are removed from the diet, the body starts burning fat for fuel and produces ketones, which reduce hunger. At the same time, eating a lot of protein tells the body to stop breaking down muscle, so weight loss comes mostly from fat. This leads to significant weight loss without losing muscle tissue.
What the research says
1 studyStudy: The Protein-Sparing Modified Fast Diet
A small study of severely obese teens who tried other diets without success found that a strict, doctor-supervised high-protein diet helped them lose about 11 pounds on average, with half losing at least 5% of their body weight and one in five losing over 10% — just like the claim says.
