Eating less protein might help people with kidney disease by reducing protein in their urine, slowing down kidney damage, and delaying the need for dialysis or transplant.

Eating too much protein might make kidney problems worse in people who already have kidney issues or are at risk for them, by putting extra strain on the kidneys and causing more damage over time.

Eating a lot of protein might make your kidneys work too hard, based on a big study of over 9,000 adults.

Eating lots of protein makes your kidneys work harder in healthy people, but it probably doesn't harm them if your kidneys are already healthy. However, if you have kidney problems, high protein might make them worse.

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

For people with kidney disease, the right amount of protein in their diet depends on their age, health, and other conditions—too little can cause poor nutrition, but too much might harm the kidneys. Doctors usually suggest between 0.6 and 1.2 grams per kilogram of body weight each day.
