How this is worked out

Studies on protein while losing weight mostly land between 1.2 and 2.0 g per kilo. The studies, and the ones that disagree

  1. Grams per kilo1.2 g without strength training. 1.6 g with it, or 2.0 g while you also lose weight. From 50 it slowly goes back to 1.2 g by 65.
  2. The weight we countYour weight, or your weight at a BMI of 27.5 if that is lower. Extra body fat does not need extra protein.
  3. RoundedTo the nearest 5 g, and never more than 45% of your calories.
