Tracking Your Macros
Macronutrients are molecules we need in large amounts, also known as the main nutrients we need to simply survive. Micronutrients, in contrast, are substances required in much smaller amounts, such as vitamins, minerals and electrolytes.
The three macronutrients are carbohydrates, proteins and fats.
Each macronutrient corresponds to a specific calorie amount per gram. Carbohydrates have four calories per gram, proteins have four calories per gram and fats have nine calories per gram.
Your macro ratio depends on your health and fitness goals, as well as how your body responds to particular foods.
