Mastering Your Macros: A Beginner's Guide

A calorie deficit dictates weight loss, but macronutrients dictate what kind of weight you lose. If you want to lose fat while retaining muscle, counting macros is superior to counting calories alone.

The Big Three

• Protein (4 calories/gram): The building block of muscle. Essential for recovery and highly satiating.
• Carbohydrates (4 calories/gram): Your body's preferred energy source. Crucial for fueling high-intensity workouts and brain function.
• Fats (9 calories/gram): Necessary for hormone production and nutrient absorption.

Using a macro calculator, you can establish a ratio that fits your goals—whether that's a high-carb split for endurance athletes or a balanced 40/30/30 (Carbs/Protein/Fat) split for general fitness and body recomposition.
