What are Macros?
Within the diet context, macros is the abbreviation for macronutrients. The prefix comes from the Greek phrase makros, which implies massive.
Merely put, macronutrients are the sorts of vitamins your physique wants day by day in massive quantities (assume grams) to keep up optimum operate.
