Description
1 study reviewed
In plain English

A specialized low-protein diet, given with medical oversight, supplements, and behavioral support, leads to rapid weight loss in severely obese adolescents who did not lose weight with standard methods.

See the scientific wording

The protein-sparing modified fast, when administered under medical supervision with nutritional supplementation and behavioral support, appears feasible as an outpatient intervention for rapid weight loss in severely obese adolescents who have failed conventional approaches.

Why this might work

When carbs and fats are removed from the diet, the body switches to burning fat for energy and produces ketones. These ketones reduce hunger signals in the brain, making it easier to eat less. At the same time, eating a lot of protein tells the body to stop breaking down muscle and instead use fat stores for fuel, leading to rapid weight loss without losing muscle.
