The Claim
In healthy adult males exposed to severe energy deficit at high altitude, a protein intake of 2.0 g/kg/day increases daily protein oxidation by 0.95 ± 0.32 g/kg/day compared to a protein intake of 1.0 g/kg/day, resulting in a more negative whole-body net protein balance.
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.
When healthy adult men are in a state of severe calorie deficit at high altitude, consuming 2.0 grams of protein per kilogram of body weight per day leads to a higher rate of protein breakdown compared to consuming 1.0 gram per kilogram, resulting in a greater overall loss of body protein.
See the scientific wording
In healthy adult males exposed to severe energy deficit at high altitude, a higher protein intake of 2.0 g/kg/day increases daily protein oxidation by 0.95 ± 0.32 g/kg/day compared to a standard intake of 1.0 g/kg/day, resulting in a more negative whole-body net protein balance.
What the research says
1 studyIn men at high altitude who weren’t eating enough calories, eating more protein made their bodies burn more protein for energy and left them with even less protein overall—exactly what the claim says. It didn’t help them keep muscle, but that’s not what the claim was about.
