Macros for 150 lb Man (Maintenance)

Quick Answer: If you’re a 150 lb man aiming for maintenance (moderately active, ~35 years old), your daily macros are approximately 2515 calories, 135g protein, 377g carbs, 52g fat — based on the Mifflin-St Jeor equation and standard sports nutrition ratios. This matches your estimated TDEE — designed to maintain your current weight.

How These Numbers Were Calculated

The macros above use a standard formula stack that registered dietitians and sports nutritionists use to set baselines:

Step 1 — BMR (Basal Metabolic Rate): Mifflin-St Jeor equation, the most-accurate validated formula for non-athletes:

• For a man at 150 lb (~68.0 kg), 5’10”, age 35: BMR ≈ 1623 calories/day

Step 2 — TDEE: BMR × activity multiplier (1.55 for moderately active — exercise 3-5 days/week):

• TDEE ≈ 2515 calories/day

Step 3 — Calorie Adjustment for Maintenance:

This matches your estimated TDEE — designed to maintain your current weight.

Step 4 — Macro Split:

• Protein: 0.9g per pound bodyweight = 135g/day — preserves and builds lean mass
• Fat: 0.35g per pound = 52g/day — minimum for hormone health
• Carbs: Remaining calories = 377g/day — fuels training and recovery

Final macros: 2515 cal / 135g P / 377g C / 52g F.

Macros at Nearby Bodyweights

If your weight differs from 150 lb, here’s how the numbers shift:

Weight	Calories	Protein	Carbs	Fat
130 lb	2375	117g	373g	46g
140 lb	2445	126g	375g	49g
150 lb	2515	135g	377g	52g
160 lb	2586	144g	376g	56g
170 lb	2656	153g	378g	59g

(Recalculate every 10-15 lbs of bodyweight change.)

What to Eat to Hit 135g Protein

A practical day for a 150 lb man:

• Breakfast (~34g protein): 3 eggs + 1/2 cup oats + Greek yogurt with berries
• Lunch (~40g protein): 4.5 oz grilled chicken + sweet potato + large salad
• Dinner (~40g protein): 4.5 oz salmon or lean beef + rice + roasted vegetables
• Snack (~20g protein): Protein shake or cottage cheese with fruit

This is one shape your day can take — the specific foods don’t matter as long as you hit the macros consistently.

Common Mistakes at 150 lb

1. Overestimating activity level — Most people set themselves at “very active” but actually average “lightly active.” Be honest.
2. Not recalculating after weight changes — Macros at 150 lb won’t work at 160 lb.
3. Hitting protein 4 days a week and “winging” 3 — 4/7 = 57% adherence = 57% of the result. Consistency matters.
4. Daily weigh-in panic — Use weekly averages, not daily fluctuations.

Frequently Asked Questions

Is 2515 calories enough for a 150 lb man?

For maintenance, yes. This puts you in a sustainable maintenance that protects metabolism and muscle. Going much further would slow results or cause rebound.

How long until I see results?

Visible body composition changes take 4-6 weeks of consistent macro tracking and training. Scale weight changes are visible in 1-2 weeks (with 2-5 lb daily fluctuations from water/sodium — use weekly averages).

Do I need to change macros on workout days vs rest days?

For most people, no — daily macros work fine. Advanced lifters may benefit from calorie cycling but it’s fine-tuning, not a starting point.

What if I’m shorter or taller than 5’10”?

Add ~50 calories for every 2” taller, subtract ~50 for every 2” shorter. For precise numbers, use our Macro Calculator.
