Maintaining 140 lb as a moderately active male means 2,320 cal daily: 120g protein, 316g carbs, 64g fat. These numbers match your 2,318 TDEE exactly, with protein weighted to hold 115 lbs of lean mass and a minor surplus capacity for muscle repair. Weekly weigh-ins matter more than daily, since food volume and water swings show up as 2 to 3 lbs of scale noise. Maintenance only works long term when paired with progressive resistance training. Without it, the body has no reason to preserve the lean tissue these macros are built to protect. Hit protein every day. Let carbs and fat flex by about 20g as training load varies.

How These Macros Were Calculated
| Body Weight | 140 lbs |
|---|---|
| Estimated Lean Mass | 115 lbs (82% of body weight) |
| Lean Mass (kg) | 52.1 kg |
| BMR (Katch-McArdle) | 1,495 cal/day |
| TDEE (BMR x 1.55) | 2,318 cal/day |
| Target Calories | 2,320 cal/day |
| Calorie Change | None (maintenance) |
| Expected Weekly Change | Stable weight |
BMR uses the Katch-McArdle formula (370 + 21.6 x lean mass kg), which accounts for lean mass and outperforms Harris-Benedict for accuracy across different body compositions. Lean mass estimated at 18% average body fat for men. Activity multiplier 1.55 = moderate exercise 3-5 days per week. These static macro guide pages use one combined activity level for readable comparisons. The interactive macro calculator separates daily movement from training for a more precise target.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 120g | 480 | 21% |
| Carbohydrates | 316g | 1264 | 54% |
| Fat | 64g | 576 | 25% |
| Total | - | 2,320 | 100% |
Protein is set at 2.3g per kg of lean body mass (115 lbs lean mass for this man). Fat targets 25% of target calories with a unisex floor of max(0.5g per kg body weight, 20% of calories) applied if the percentage drops below it. Carbs fill the remaining calories, with a 50g minimum for brain function.

How to Hit These Macros Daily
Buy a digital food scale
A food scale eliminates the single biggest source of calorie miscalculation: eyeballed portions. A $15 scale pays for itself the first week by surfacing hidden 200 to 400 cal overshoots. Required for hitting 2320 cal precisely.
Plan 3 meals that total 2320 calories
Divide daily calories evenly: roughly 773 cal per meal for a 140 lb man. Each meal targets about 40g protein, 105g carbs, and 21g fat.
Hit 120g protein first
Protein is the lock, carbs and fat are the flex. 120g across 3 meals is 40g each. Pick one anchor protein source per meal (chicken, beef, fish, Greek yogurt, eggs) and portion it before adding anything else. If you fall short on calories by bedtime, top up with carbs or fat, not extra protein.
Split carbs and fat around training
Put 79g of your 316g carbs in the meal 1-2 hours pre-workout and 95g in the post-workout meal. Spread fat evenly across remaining meals. Carb timing matters for training quality on a target.
Track every input for 14 days
Log every meal, snack, drink, and cooking oil for 14 days using any tracking app. No eyeballing. The calibration period surfaces blind spots: dressings, condiments, weekend drift. After 14 days, tracking becomes automatic.
Adjust by 100 cal weekly based on the scale trend
Step on the scale 5 mornings a week, average the readings. Compare to last week. If the weekly average drifts more than 1.5 lbs in either direction, adjust 100 cal opposite the drift. Never adjust on a single day's reading.
What This Looks Like In Practice
Meal timing and structure
At maintenance, meal timing is flexible because total calories are the main lever. 3 to 4 meals works for most schedules. A 140 lb man holding 2320 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 120g of protein total and staying within ±100 cal of target on a weekly average. Consistency at the week level beats precision at the meal level.
Training day nutrition
At maintenance for a 140 lb man, train to preserve or slowly build lean mass. Pre-workout, 79g of your 316g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 95g of carbs plus 30g to 40g protein replenishes glycogen and triggers synthesis. Lifting 3 to 4 times per week with progressive overload is what keeps the 120g protein target from becoming wasted at 2320 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 2318 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 140 lb man on 2320 cal, the biggest pitfall is drift. Weight creeps up 2 to 3 lbs over a month, scale moves feel noisy, and six months later the baseline is 7 lbs heavier. Fix this with a weekly average: step on the scale 5 mornings a week, take the 7-day average, compare week-over-week against your 140 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 2318 TDEE, which turns 2320 into 2220+ effective cal within a year. Lift 3 times a week minimum at 120g protein daily.
Frequently Asked Questions
Is 2320 calories per day too fixed for a 140 lb male?
2320 matches a 2318 TDEE almost exactly. For a 140 lb man at moderately active activity, this is the calibration where body weight holds steady on a weekly average. Daily scale moves of 1-3 lbs are water and gut content, not fat. If the 7-day average trends in either direction for 3 weeks, adjust by 100 cal in the opposite direction.
How should I distribute 120g of protein across the day for muscle protein synthesis?
Spread 120g across 4 meals of roughly 30g each, spaced 3-5 hours apart. Each meal hits the leucine threshold needed to trigger muscle protein synthesis. A 30-40g casein or Greek yogurt dose before sleep extends overnight synthesis — especially valuable during recomposition.
Can I swap carbs for fat or vice versa within my 2320 calorie target?
Yes. Keep protein fixed at 120g and swap carbs and fat freely — 10g of fat trades for ~23g of carbs. Two floors: fat above 52g (20% of calories) and carbs above 50g. Hit protein, land at 2320 calories, and the carb-fat split is yours.
Should I drink my calories or eat them at 140 lbs?
Mix both. At maintenance, there is no forcing function. Whole foods deliver micronutrients and fiber that liquid calories skip. A protein shake post-workout plus 3-4 solid meals is the cleanest split. If you enjoy a daily smoothie or latte, count the calories against 2320 and move on. Alcohol is the single biggest blind spot, 150-300 cal per drink with zero satiety.
How were the macros calculated for a 140 lb male?
The calculation uses the Katch-McArdle BMR formula. A 140 lb man with an estimated 82% lean mass (115 lbs lean) has a BMR of 1495 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 2318 calories per day. For maintenance, the target matches TDEE at 2320 calories.
Why is protein 120g for maintenance at 140 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 140 lb man with 115 lbs of lean mass needs 120g of protein per day. At maintenance, 2.3g per kg of lean mass supports daily muscle repair and satiety.
When to Recalculate These Macros
Weight trending upward over 2 weeks
Reduce by 100-150 cal/day from carbs. Your actual TDEE is slightly below the 1.55x estimate for moderately active activity.
Weight trending downward over 2 weeks
Add 100-150 cal/day from carbs or fat. You may be more active than the multiplier accounts for, or your metabolism has adapted upward.
Activity level has changed significantly
Switch to the matching activity level using the selector above. The difference between sedentary and moderately active can be 300-500 cal/day at 140 lbs.
