Understanding Calories and Macros Together

Calories determine whether you gain, lose, or maintain weight.

Macros determine the quality and balance of those calories.

For example:

Too many fats may increase calorie intake quickly
Too few carbs may reduce workout performance

Balancing all three macronutrients properly is essential for long-term success.
