What Are Macronutrients?

Macronutrients (macros) are the three primary nutrients that provide energy: protein, carbohydrates, and fat. Each serves distinct functions in the body, and the ratio you consume significantly impacts body composition and performance.

Calorie Density of Each Macro

  • Protein: 4 calories per gram
  • Carbohydrates: 4 calories per gram
  • Fat: 9 calories per gram

Protein Recommendations

For muscle building and retention, most research supports 1.6–2.2 g of protein per kg of body weight per day. Higher protein also aids satiety during weight loss, helping reduce overall calorie intake.

How to Use Macro Targets

  1. Calculate your TDEE (daily calorie need).
  2. Set a calorie target (deficit for loss, surplus for gain, maintenance for body recomposition).
  3. Apply the macro ratio to your calorie target to get grams per day.
  4. Use a food tracking app (MyFitnessPal, Cronometer) to hit daily targets.

Frequently Asked Questions

For general fitness, 1.6-2.2g per kg of body weight is recommended. Endurance athletes may need less; strength athletes may benefit from up to 2.5g/kg.
Macronutrients are protein (4 kcal/g), carbohydrates (4 kcal/g), and fat (9 kcal/g). They provide energy and essential nutrients for body function.
Calorie balance determines weight change, but macros influence body composition. Tracking macros is more effective for body recomposition goals.
