Macros for 110 lb Man (Weight Loss)

Quick Answer: If you’re a 110 lb man aiming for weight loss (moderately active, ~35 years old), your daily macros are approximately 1784 calories, 110g protein, 251g carbs, 38g fat — based on the Mifflin-St Jeor equation and standard sports nutrition ratios. This is a 450-calorie deficit below your TDEE of 2234 — designed to lose about 0.5-0.75 lb/week without crashing metabolism.

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 Weight Loss:

This is a 450-calorie deficit below your TDEE of 2234 — designed to lose about 0.5-0.75 lb/week without crashing metabolism.

Step 4 — Macro Split:

• Protein: 1.0g per pound bodyweight = 110g/day — preserves and builds lean mass
• Fat: 0.35g per pound = 38g/day — minimum for hormone health
• Carbs: Remaining calories = 251g/day — fuels training and recovery

Final macros: 1784 cal / 110g P / 251g C / 38g 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	1644	90g	251g	31g
100 lb	1714	100g	250g	35g
110 lb	1784	110g	251g	38g
120 lb	1854	120g	249g	42g
130 lb	1925	130g	248g	46g

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

What to Eat to Hit 110g Protein

A practical day for a 110 lb man:

• Breakfast (~28g protein): 3 eggs + 1/2 cup oats + Greek yogurt with berries
• Lunch (~33g protein): 3.3 oz grilled chicken + sweet potato + large salad
• Dinner (~33g protein): 3.3 oz salmon or lean beef + rice + roasted vegetables
• Snack (~16g 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 100 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 1784 calories enough for a 110 lb man?

For weight loss, yes. This puts you in a sustainable deficit 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.
