How much protein is too much? If you have kidney problems, the American Diabetes Association suggests you get just 15% to 20% of your calories from protein. And do your heart a favor: Choose protein such as beans, fish, or chicken more often than fatty cuts of meat.
If you want to lose weight, eat a balanced diet that cuts calories by 500 calories a day. You should be able to lose 10% of your body weight without putting your kidneys at risk.
