The Basics
Understanding Macros
Why do macronutrients matter?
Calories determine whether you gain or lose weight, but macronutrients determine what that weight is (muscle vs fat) and how you feel. Balancing protein, carbs, and fats ensures your body has the materials it needs to repair tissue, produce energy, and regulate hormones.
What is the best ratio?
There is no single "best" ratio. However, a balanced approach like 30% Protein, 30-35% Fat, and 35-40% Carbs works well for most people. Athletes may need more carbs, while those on keto will prioritize fats. This calculator uses a balanced moderate-carb approach suited for general fitness.
