The article is fantastic with only one caveat. Recommending 1.6 g of protein per kg of body weight to people who are only meeting, not exceeding, physical activity recommendations is foolish. 1.6 if amount that one needs to build maximum muscle mass in the shortest possible time. Leading protein intake researchers (think people like Stu Philips) state that that recommendation is excessive for most people and he instead suggests 1.2 g for nearly everyone.
