Calories: Protein × 4 + Carbs × 4 + Fat × 9 = Total Calories
Protein and carbs = 4 cal/g each. Fat = 9 cal/g. Alcohol = 7 cal/g.

Macronutrient Balancing for Body Composition

While calorie deficits dictate whether you lose weight, macronutrients (protein, carbohydrates, and fats) dictate what kind of weight you lose. Tracking your macro split ensures you lose fat rather than lean muscle tissue, while maintaining the hormonal health and energy levels necessary for active living.

Roles of the Three Macros:

  • Protein (4 cal/g): Essential for muscle repair and preservation. High protein also increases satiety and TEF.
  • Carbohydrates (4 cal/g): The body's preferred source of high-intensity fuel. Vital for exercise performance and recovery.
  • Fats (9 cal/g): Crucial for hormone regulation, vitamin absorption, and brain health.

❓ Frequently Asked Questions

A common starting point is 30% protein, 35% carbs, 35% fat. Higher protein (35-40%) helps preserve muscle and increases satiety. Lower carbs work for some people. Experiment and find what keeps you full and energized.
Aim for 0.7-1.0 grams per pound of body weight (or 1.6-2.2 g/kg). Higher protein preserves muscle during deficit, keeps you full, and has a higher thermic effect (burns more calories during digestion).
Calories determine weight loss. Macros determine how you feel, look, and perform. Tracking macros ensures adequate protein for muscle, healthy fats for hormones, and enough carbs for energy. Start with calories, add macros when ready.
Fat is essential for hormone production, vitamin absorption, and cell health. Going below 20% of calories from fat can cause hormonal issues, dry skin, and decreased satiety. Aim for at least 0.3g per pound of body weight.
