If you're overweight or obese and on a high-protein diet to lose weight, your kidneys stay just as healthy — or may even get a little better — even if you already have mild kidney issues, high blood pressure, or type 2 diabetes.
If you're an adult who's overweight and has mild kidney disease, losing weight on a high-protein diet might actually help your kidneys a little over 8 months — even if you eat up to 1 gram of protein per pound of body weight each day.
Eating a lot of protein every day — even more than 200 grams — won’t hurt your kidneys if they’re already healthy.
If you're overweight and your kidneys are working too hard at the start, going on a high-protein diet to lose weight might make your kidney function look more normal—not worse—by bringing down their overactivity.
People who are overweight or obese can lose about 14.5 kg in around 8 months on a high-protein, low-carb diet, mostly from fat, while even gaining a little muscle.
