Answer key: Protein worksheet

  1. 1. General protein range: 92–115 g per day

    1. Find the low end: multiply your weight by 0.8 grams for each kilogram, the bottom of the mostly inactive band

      115 kg×0.8 g/kg=92 g
    2. Find the high end: multiply your weight by 1 grams for each kilogram, the top of the band

      115 kg×1 g/kg=115 g
    3. Round both ends to the nearest gram to get your daily range

      92–115 g per day
