Research on athletes who lift weights and eat lots of protein found no kidney problems, but the studies were mainly checking for muscle or fat changes, not kidney health.

If you lift weights and eat lots of protein, you’ll likely build more muscle and get stronger than if you just do one or the other—because together, they work better than alone.

Eating a lot of protein every day — even more than 200 grams — won’t hurt your kidneys if they’re already healthy.
