Frequently asked questions

What is the difference between macros and calories?

Calories measure the energy in food as a single number. Macros describe where that energy comes from, splitting it into protein, carbohydrate and fat. Two meals can carry the same calories while having very different macros.

What is the difference between macros and micros?

Macros, or macronutrients, are the nutrients eaten in gram quantities that supply energy: protein, carbohydrate and fat. Micros, or micronutrients, are vitamins and minerals, needed in far smaller amounts and supplying no energy. The distinction is one of quantity and function, not importance.

Is alcohol a macro?

Alcohol supplies energy but is not one of the three macronutrients, and most tracking tools list it separately or fold its energy into the carbohydrate line. Because the treatment varies between tools, totals for the same drink can differ.
