Tracking the amount of food you eat is key to accomplishing health, performance or aesthetic goals. While the Zone has been a staple in CrossFit, macronutrient (macro) tracking has become increasingly popular. Both programs require eating a prescribed amount of food every day, but caloric totals rarely match when the exact same meals are evaluated in each system.
This brief neither criticizes nor applauds either system, nor does it discuss how much of each macronutrient someone should eat. Instead, this brief demonstrates and explains the differences in caloric measurement between the two systems so athletes can optimize their approaches.
