If a man weighs 190 lb and eats 150 g protein per day, his protein intake is _____ of the recommended dietary allowance (rda)

The RDA for protein is 0.8 g per kilogram of body weight. This man's weight is 190 lb, or 86 kg; 86 kg × 0.8 = 69.1 g protein per day. Thus, an intake of 150 g is more than twice his RDA of 69.1 g of protein per day.

Recommended Dietary Allowance (RDA) of protein for adults is 0.8 g per kilogram of body weight. To determine your RDA for protein, multiply your weight in pounds by 0.36.The protein RDA for adults is 0.8 grams per kilogram of healthy body weight per day.
