What Should My Macros Be to Lose Fat?

To lose fat, most evidence-based approaches set protein at 1.6 to 2.2 grams per kilogram of body weight, reduce calories moderately, and let carbs and fats fill the remainder. Those ratios create the energy deficit and satiety needed for fat loss while protecting lean mass.

How to Calculate Your Fat-Loss Macros

Start with your total daily energy expenditure and subtract 300 to 500 calories to get your fat-loss target. From there, assign protein first, then fat, and let carbs take what is left.

Step-by-step macro allocation

• Estimate protein at 1.6 to 2.2 g per kg of body weight.
• Set fat at 0.8 to 1.2 g per kg to support hormones.
• Fill remaining calories with carbohydrates.

A 70 kg person eating 1,800 calories might aim for 140 g protein, 65 g fat, and 145 g carbs. Those numbers shift with body size, activity level, and preferences.

Why Protein Matters Most

Protein preserves muscle in a calorie deficit, increases diet-induced thermogenesis, and improves satiety. Most fat-loss plans prioritize protein above all else because it is the macronutrient with the strongest effect on body composition.

Carbs and Fat: How to Split the Remainder

Carbs fuel training and brain function; fat supports hormone production. Lower-carb approaches can work if they are sustainable, but very low fat intake can disrupt hormones over time. A balanced split usually works better for most people.

When to Adjust Your Macros

If weight loss stalls for two or more weeks, reduce calories by 100 to 150 or add activity. Reassess protein intake if body weight drops significantly, because your grams per kilogram target may change.

Common Mistakes

• Setting protein too low and losing muscle.
• Cutting fats so low that hunger and hormonal issues increase.
• Ignoring total calories while obsessing over macro ratios.

The best macro plan is one you can follow consistently while losing fat at a moderate pace.
