The Claim
In athletic populations, adding protein to a carbohydrate and water intake regimen (35 ± 26 g PRO; 0.5 ± 0.4 g PRO·kg⁻¹) does not significantly alter subsequent athletic performance compared to carbohydrate and water alone (115 ± 61 g CHO; 0.6 ± 0.3 g CHO·kg⁻¹·h⁻¹; 1.2 ± 0.6 L), when carbohydrate or total energy intake is matched, with a mean change in power output of 0.5% (95% CI: -0.5 to 1.6%).
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.
Adding protein to carbs and water doesn’t really help or hurt your workout performance if you're already getting the same amount of energy.

What the research says
1 studyThe study looked at whether adding protein to carbs and water helps athletes perform better in a second workout soon after the first. It found that adding protein didn’t make a meaningful difference compared to carbs and water alone.
