How It Works

Macros are calculated from your target daily calories using percentage splits. Protein and carbohydrates each provide 4 calories per gram. Fat provides 9 calories per gram. A Balanced split (30/35/35 protein/fat/carbs) on 2,000 calories = 150g protein, 78g fat, 175g carbs.

Tips & Shortcuts

Protein should be prioritized first when setting macros — it protects muscle during a deficit and promotes satiety.

Fat intake should never drop below 0.3g/lb bodyweight (0.6g/kg) to maintain hormone production.

Carbs are the most flexible macro — adjust them last after setting protein and fat minimums.

Common Mistakes

Focusing only on calories and ignoring protein

Without adequate protein (1.6–2.2g/kg), weight loss comes from both fat and muscle. Hitting your protein target protects muscle mass.

Following the same macro split regardless of goal

A cutting phase needs higher protein (35–40%), while a bulking phase can have more carbs. Goals should determine your split.

Frequently Asked Questions

Macronutrients — protein, carbs, and fat — are the three energy sources. Protein and carbs each provide 4 cal/g; fat provides 9 cal/g. Tracking macros optimizes body composition beyond calorie counting alone.

For muscle gain, aim for 0.7–1g of protein per pound of bodyweight (1.6–2.2g/kg). Higher protein also protects muscle during a calorie deficit.

Keto is typically 70–75% fat, 20–25% protein, and 5–10% carbs (under 50g net carbs daily), forcing the body into ketosis.
