Macros (Macronutrients)
What is Macros (Macronutrients)?
Protein, carbohydrates, and fats — the nutrients that provide calories.
Why it matters
Macro balance affects body composition, performance, and satiety at the same calorie level.
How it works
Protein and carbs have ~4 kcal/g; fat has ~9 kcal/g. Allocate macros within your calorie target.
Examples
- For a 2,000 kcal diet, 150g protein (600 kcal), 250g carbs (1,000 kcal), 67g fat (600 kcal).
- Bodybuilder: 2.5g/kg protein for muscle repair; endurance athlete: higher carbs for glycogen.
- Vegan: Plant proteins like lentils; keto: high fat, low carb.
- Weight loss: Moderate protein and carbs; bulk: higher carbs for energy.
- Diabetic: Controlled carbs to manage blood sugar.
Common mistakes
- Ignoring protein for muscle preservation
- Too low fat causing hormone issues
- Over-relying on carbs without balance
- Not adjusting for activity levels
- Focusing only on macros, neglecting micros
