Macros for 110 lb Man (Muscle Gain)

Quick Answer: If you’re a 110 lb man aiming for muscle gain (moderately active, ~35 years old), your daily macros are approximately 2484 calories, 121g protein, 426g carbs, 33g fat — based on the Mifflin-St Jeor equation and standard sports nutrition ratios. This is a 250-calorie surplus above your TDEE of 2234 — designed for slow, lean muscle gain (~0.5 lb/week) with minimal fat regain.

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 110 lb (~49.9 kg), 5’10”, age 35: BMR ≈ 1441 calories/day

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

• TDEE ≈ 2234 calories/day

Step 3 — Calorie Adjustment for Muscle Gain:

This is a 250-calorie surplus above your TDEE of 2234 — designed for slow, lean muscle gain (~0.5 lb/week) with minimal fat regain.

Step 4 — Macro Split:

• Protein: 1.1g per pound bodyweight = 121g/day — preserves and builds lean mass
• Fat: 0.3g per pound = 33g/day — minimum for hormone health
• Carbs: Remaining calories = 426g/day — fuels training and recovery

Final macros: 2484 cal / 121g P / 426g C / 33g F.

Macros at Nearby Bodyweights

If your weight differs from 110 lb, here’s how the numbers shift:

Weight	Calories	Protein	Carbs	Fat
90 lb	2344	99g	426g	27g
100 lb	2414	110g	426g	30g
110 lb	2484	121g	426g	33g
120 lb	2554	132g	426g	36g
130 lb	2625	143g	425g	39g

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

What to Eat to Hit 121g Protein

A practical day for a 110 lb man:

• Breakfast (~30g protein): 3 eggs + 1/2 cup oats + Greek yogurt with berries
• Lunch (~36g protein): 3.3 oz grilled chicken + sweet potato + large salad
• Dinner (~36g protein): 3.3 oz salmon or lean beef + rice + roasted vegetables
• Snack (~18g 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 110 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 110 lb won’t work at 120 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 2484 calories enough for a 110 lb man?

For muscle gain, yes. This puts you in a sustainable surplus 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.
