Overeating Protein Makes More Muscle (Not Fat)

Jan 15, 2026

Description

If you were a scientist and you wanted to understand if excess dietary protein turns into muscle or fat, an effective way to do that would be to get some volunteers to check into an inpatient metabolic ward and feed them a lot of protein. This is exactly what a group of researchers did. They found that when higher protein levels are consumed alongside excess calories, the protein is not converted into fat and stored but instead increases lean mass. In this video, I’ll explain important points from the study and tell you how much protein you need to eat to mimic the participant's results.
