Why count macros instead of calories?

Short Answer

When you count macros, you are counting calories. Just more detailed.

Long Answer

While in all but extreme circumstances a calorie is just a calorie[1],[2] and you can count just calories to lose weight or gain weight. Calories in vs Calories Out (CICO) is what determines weight gain or loss.

CICO = weight loss or gain
Protein = Body composition/muscle building
Carbs = Performance
Fats = Hormones
