Nutrition Basics: Macronutrients and Calories Explained
Published by Rajesh Kumar on 08 Jun, 2026
Every weight loss or muscle building goal begins with understanding calories and macronutrients. A calorie is a unit of energy. Your body burns a baseline number of calories called the Basal Metabolic Rate (BMR) just to stay alive. The food we eat consists of three primary macronutrients:
1. Protein: 4 calories per gram. Crucial for repairing muscle fibers.
2. Carbohydrates: 4 calories per gram. The primary fuel source for high-intensity workouts.
3. Fats: 9 calories per gram. Vital for hormone regulation, brain function, and joint health.
Balancing these macros is the secret to custom fitness planning.
