How much protein do I need a day?
The everyday minimum for adults is about 0.8 g per kilogram of body weight. Active adults usually do better with 1.2 to 1.6 g/kg, and 1.6 to 2.2 g/kg when building muscle or losing fat. Adults 65 and over need at least 1.0 to 1.2 g/kg.
Can you eat too much protein?
Most healthy adults do fine up to about 2 grams per kilogram. Beyond that it mostly adds calories. If you have kidney disease, follow your doctor’s advice.
Do I need protein shakes?
No. They’re a convenient option, but food works just as well. Eggs, yogurt, fish, chicken, beans, lentils and tofu are all great sources.
Can I get enough protein from plants?
Yes. Mix beans, lentils, tofu, tempeh, edamame, whole grains, nuts and seeds through the day. You may want to aim for the higher end of your range.
Is protein per pound or per kilogram?
Both work. Divide grams per kilogram by 2.2 to get grams per pound. For example, 1.6 g/kg is about 0.73 g/lb.
Can I use this if I’m pregnant, breastfeeding or under 18?
Please don’t rely on it. These estimates are for healthy adults. If you’re pregnant or breastfeeding, under 18, have a medical condition or follow a diet your doctor prescribed, talk to your doctor or a licensed dietitian first.
