Estimated reading time: 1 min


“Should I change my macros?” The question that floods the email inbox of almost all coaches who work with clients. This NutriWiki will give a breakdown of if and when you need to change macros.


When progress stalls, there is rarely a need to change macros if what you’re doing is working.

If progress stalls for an extended period of time and you need to adjust your macros, an easy recommendation is to decrease by ~100 Calories from carbs & fats when dieting (e.g. 20C & 2F) or increase by the same amount when bulking. There may be a need to change things by more than 100 calories in certain situations.
