Macros for Men: How to Calculate Protein, Carbs, and Fat for Your Goal

I write a lot for women, it's where most of my coaching work lives, but the men in my clients' lives kept borrowing their partners' macro numbers and wondering why things felt off. So let's do this one properly, built from the ground up around male physiology: higher lean mass, considerably higher testosterone, larger calorie needs, and typically different body-composition goals. All of that changes the numbers in ways that matter. Whether you're cutting fat, building muscle, or recomposing, here's exactly how to set yours.

How Men's Macro Needs Differ

Men generally have:

• More lean muscle mass, higher resting metabolic rate, better carbohydrate utilisation
• Higher testosterone, greater anabolic response to protein, faster recovery
• Higher TDEE, more total calories available to distribute across macros
• Different body fat distribution, visceral fat tends to accumulate first; subcutaneous fat around abs rather than hips/thighs

These differences affect macro targets, particularly carbohydrate allocation and calorie totals.

Calculating Your Calorie Baseline (TDEE)

Before setting macros, you need your TDEE (Total Daily Energy Expenditure).

BMR for men (Mifflin-St Jeor): BMR = (10 × weight kg) + (6.25 × height cm) − (5 × age) + 5

Multiply by activity factor:

Example, 32-year-old man, 85kg, 180cm, moderately active: BMR = (850) + (1,125) − (160) + 5 = 1,820 kcal TDEE = 1,820 × 1.55 = 2,821 kcal/day

→ Use the TDEE Calculator to skip the arithmetic.

Macro Targets by Goal

Fat Loss

Calorie target: TDEE − 400-600 kcal

For our example man: 2,221-2,421 kcal/day

Key principle: Keep protein high (1.8-2.2g/kg) to preserve muscle during the deficit. For an 85kg man, this means a minimum of 153-187g protein/day.

Muscle Building (Lean Bulk)

Calorie target: TDEE + 200-350 kcal

For our example man: 3,021-3,171 kcal/day

Higher carbohydrates support training intensity and glycogen replenishment, this is where muscle building advantage compounds.

Body Recomposition (Maintaining weight, changing composition)

Calorie target: TDEE (±100 kcal)

Body recomposition works best for men who are new to training or returning after a break. Very high protein is critical, the excess above muscle synthesis needs is costly but the signal-to-noise ratio improves significantly.

Maintenance

Calorie target: TDEE

Protein: The Non-Negotiable

Regardless of goal, protein is the most important macro to get right:

• Fat loss: 1.8-2.4g/kg to prevent muscle breakdown
• Muscle building: 1.6-2.2g/kg, more isn't more beneficial
• Maintenance: 1.4-1.8g/kg, for athletic performance and health

Carbohydrates: Fuelling Training

Men typically tolerate higher carbohydrate intakes well, particularly around training. Strategic carb placement:

• Pre-workout (60-90 min before): 30-60g complex carbs (oats, rice, sweet potato)
• Post-workout (within 2 hours): 40-80g fast carbs + 30-40g protein (white rice + chicken; shake + banana)
• Rest day: Reduce carbs by 20-30%, increase fat slightly

Best carb sources:

• White rice, brown rice, sweet potato, oats, whole wheat pasta, fruit, legumes

Fat: Hormonal Health

Men with low dietary fat experience significant testosterone suppression. The minimum fat intake for hormonal health is approximately 0.8g/kg. Men on cutting diets who drop fat too low (below 15% of calories) frequently see reduced libido, recovery, and training performance.

Recommended fat sources: Olive oil, avocado, nuts, oily fish, eggs

A Day of Eating at Your Macros

Example: 85kg man, fat loss phase, 2,300 kcal, 200g protein / 230g carbs / 64g fat

Adjust portions up to hit full targets, this is a framework, not a rigid prescription.

Common Mistakes Men Make With Macros

1. Ignoring fat when bulking, sauces, cooking oil, and fatty cuts add up fast. A "clean bulk" with 4,000 kcal from McDonald's is not the same as 4,000 kcal from rice, chicken, and olive oil.

2. Not enough protein on a cut, the most common cause of losing muscle alongside fat during a deficit. Keep protein at minimum 1.8g/kg even when cutting hard.

3. Overestimating calorie burn, fitness watches overestimate burn by 15-40%. Use the TDEE Calculator not your watch to set your calorie target.

4. Weekend drift, a 700 kcal daily deficit Monday-Friday + two 1,000 kcal surplus days Saturday-Sunday = 1,500 kcal weekly deficit instead of 3,500. Consistency matters more than weekday perfection.

The Bottom Line

Men's macro needs are higher in total calories and protein than often quoted, especially during active training. Calculate your TDEE, set protein at 1.6-2.2g/kg, and split remaining calories between carbs and fat at your preferred ratio.
