How Protein Intake Effects our Body

Although recent scientific research has provided some support for the idea that regular strength training increases dietary protein needs, these data indicate any benefit appears to plateau at protein intakes around 1.5 g/kg/day. In contrast, there are some data suggesting that much greater protein intakes enhance muscle size and strength gains even further; however, it is possible that these latter studies were confounded by interacting effects from exogenous anabolic agent use and/or by variable training/peaking preparations due to the timing of competitions held during the data collection. Despite these experimental limitations, many strength athletes are convinced that these high-protein intakes are advantageous. If so, it should be possible not only to document this in a controlled setting, but also to clearly describe the underlying mechanism responsible. This needs to be done before such high­protein intakes can be recommended.
