Nutrition Calculator

This package helps you calculate your Maintenance Calories and Macronutrient breakdown based on your activity level and caloric needs. The package provides an easy-to-use method for determining how many calories you need to maintain your current weight and how to distribute those calories across macronutrients (carbs, proteins, and fats).
