In regards to pwo carbs.... If I have say 33-35g carbs and 160cals pwo....how does that work ? because 1g carbs=4 cals, so doing the math for 33-35g carbs would only be 132-140cals....... I'm missing something.. Also, what is the recommended pwo carbs/cal for a larger person.... 255lbs to be exact....trying to help out a friend and I'm not sure what to tell him. Thanks!
