                                The Recommended Dietary Allowance (RDA) for protein for a sedentary adult is just 0.8 grams per kilogram of body weight, or about 50 grams for a 140-pound individual. However, whether 90 grams of protein per day is sufficient depends heavily on your individual circumstances, including your age, activity level, and health goals.
