General guidance, not medical advice; ask a doctor with kidney disease or a medical diet. Everything is calculated in your browser; nothing you type is uploaded.
Targets are grams per kilogram: 0.8–1.0 for general health, 1.2–1.6 for regular exercise, 1.6–2.2 to build muscle, 1.8–2.4 while losing fat and 1.0–1.2 over 65, plus 25 g a day in late pregnancy or breastfeeding.
A 70 kg person who exercises regularly needs about 84–112 g of protein a day, or 21–28 g in each of four meals.
