While consuming meat in general isn't particularly harmful, having too much of it in your diet isn't good for your kidneys. Excess protein in your diet can create or exacerbate existing renal issues because of the burden protein places on the kidneys. With the extra weight wearing on the kidneys, it's harder to remove urea waste from the body. In fact, excess meat can also cause calcium oxalate stones to form due to the acidic residue animal meat leaves behind. The body favors an alkaline state, so it tries to remove calcium to return to it. Not only will your bones suffer for it, but the stones don't feel good either.
