A 70 kg adult male requires approximately 0.8 g of protein per kilogram of body weight per day. How many grams of protein does this individual require daily?

The daily protein requirement is calculated by multiplying body weight by the recommended intake: 70 kg × 0.8 g/kg = 56 g per day. Option A (42 g) results from using 0.6 g/kg, option C (63 g) from 0.9 g/kg, and option D (70 g) from 1.0 g/kg, all of which are incorrect application of the given rate.
