What is a potential downside of high-protein diets for athletes?

High-protein diets are popular among athletes for their potential benefits in muscle repair and growth; however, one of the notable downsides is the increased risk of kidney strain and dehydration. This is particularly significant for athletes engaged in intense training, as a high intake of protein can put extra stress on the kidneys. The body has to work harder to metabolize the excess nitrogen found in protein, which can lead to various issues, especially in individuals with pre-existing kidney conditions.

Additionally, when protein intake is significantly increased, it can lead to dehydration. This can occur because the kidneys require a sufficient amount of water to excrete the byproducts of protein metabolism. If fluid intake doesn't increase in tandem with protein consumption, athletes may find themselves at risk for dehydration, which can detrimentally affect performance, recovery, and overall health.

Understanding these potential downsides helps athletes make informed dietary choices that can optimize performance while minimizing health risks.
