A 180 lb very active male maintains current weight on 3,131 calories a day, matched exactly to a 3,131 TDEE. Protein at 154g protects the 148 lbs of lean mass that drive your metabolism, while 433g of carbs support energy demand and 87g of fat covers hormonal baseline. Maintenance is not passive, it is calibration. Body weight should drift within about 1.5 lbs over any four-week window. If the scale climbs outside that band, trim 150 cal. If it drops, add 150. This is also the setup for slow recomposition: lean mass up, body fat down, body weight flat, driven by training quality rather than calorie cuts.

Eating at TDEE with zero deficit or surplus. These macros maintain your 180 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 180 lbs |
|---|---|
| Estimated Lean Mass | 148 lbs (82% of body weight) |
| Lean Mass (kg) | 66.9 kg |
| BMR (Katch-McArdle) | 1,815 cal/day |
| TDEE (BMR x 1.725) | 3,131 cal/day |
| Target Calories | 3,131 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 1.725 = hard exercise 6-7 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 | 154g | 616 | 20% |
| Carbohydrates | 433g | 1732 | 55% |
| Fat | 87g | 783 | 25% |
| Total | - | 3,131 | 100% |
Protein is set at 2.3g per kg of lean body mass (148 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 3131 cal precisely.
Plan 3 meals that total 3131 calories
Divide daily calories evenly: roughly 1044 cal per meal for a 180 lb man. Each meal targets about 51g protein, 144g carbs, and 29g fat.
Hit 154g protein first
Protein is the lock, carbs and fat are the flex. 154g across 3 meals is 51g 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 108g of your 433g carbs in the meal 1-2 hours pre-workout and 130g 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 180 lb man holding 3131 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 154g 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 180 lb man, train to preserve or slowly build lean mass. Pre-workout, 108g of your 433g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 130g 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 154g protein target from becoming wasted at 3131 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 3131 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 180 lb man on 3131 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 9 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 180 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 3131 TDEE, which turns 3131 into 3031+ effective cal within a year. Lift 3 times a week minimum at 154g protein daily.
Frequently Asked Questions
What should I do if I'm not maintaining weight at 3131 calories?
If your weight trends up or down consistently over 2 weeks at 3131 calories, your actual TDEE differs from the estimate. Adjust by 100 calories in the direction that corrects the trend. Recalculate every time you change activity level significantly.
How long should I stay in a maintenance phase at 3131 calories?
Maintenance phases should last 4-8 weeks between a cut and a bulk. They reset hunger hormones, establish a new weight set point, and give your body a break from the stress of a deficit or surplus.
Should I eat more on training days at 3131 calories?
Calorie cycling is not necessary for most people. Consistent daily targets outperform complex cycling protocols. If you want to try it, shift 10-15% of calories from rest days to training days while keeping the weekly total at 21917 calories.
Is 3131 calories per day too fixed for a 180 lb male?
3131 matches a 3131 TDEE almost exactly. For a 180 lb man at very 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 154g of protein across the day for muscle protein synthesis?
Spread 154g across 5 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 3131 calorie target?
Yes. Keep protein fixed at 154g and swap carbs and fat freely — 10g of fat trades for ~23g of carbs. Two floors: fat above 70g (20% of calories) and carbs above 50g. Hit protein, land at 3131 calories, and the carb-fat split is yours.
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 1.725x estimate for very 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 180 lbs.
