A 180 lb lightly active male maintains current weight on 2,497 calories a day, matched exactly to a 2,496 TDEE. Protein at 154g protects the 148 lbs of lean mass that drive your metabolism, while 315g of carbs support energy demand and 69g 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 1.375) | 2,496 cal/day |
| Target Calories | 2,497 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 1.375 = light exercise 1-3 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 | 25% |
| Carbohydrates | 315g | 1260 | 50% |
| Fat | 69g | 621 | 25% |
| Total | - | 2,497 | 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 2497 cal precisely.
Plan 3 meals that total 2497 calories
Divide daily calories evenly: roughly 832 cal per meal for a 180 lb man. Each meal targets about 51g protein, 105g carbs, and 23g 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 79g of your 315g 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 180 lb man holding 2497 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, 79g of your 315g 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 154g protein target from becoming wasted at 2497 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 2496 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 180 lb man on 2497 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 2496 TDEE, which turns 2497 into 2397+ effective cal within a year. Lift 3 times a week minimum at 154g protein daily.
Frequently Asked Questions
Should I drink my calories or eat them at 180 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 2497 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 180 lb male?
The calculation uses the Katch-McArdle BMR formula. A 180 lb man with an estimated 82% lean mass (148 lbs lean) has a BMR of 1815 calories. Multiplied by 1.375 for lightly active activity (Light exercise 1-3 days per week), the TDEE is 2496 calories per day. For maintenance, the target matches TDEE at 2497 calories.
Why is protein 154g for maintenance at 180 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 180 lb man with 148 lbs of lean mass needs 154g of protein per day. At maintenance, 2.3g per kg of lean mass supports daily muscle repair and satiety.
How much weight will I change at 2497 calories?
At 2497 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for lightly active activity. If you consistently gain or lose weight at this intake, your actual TDEE differs from the estimate.
Why is fat set at 69g for a maintenance diet?
Fat is set at 25% of total calories, which is 621 calories or 69g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Bulking and maintenance use 25% fat for steady hormonal support. A unisex floor of max(0.5g per kg body weight, 20% of calories) protects testosterone and estrogen below the percentage target.
How do I split 154g of protein across meals?
Across 3 meals, each meal needs about 51g of protein. Across 5 meals or snacks, each needs about 31g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 51g per meal in 3 meals is within the optimal 30-40g range.
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 1.375x estimate for lightly 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.
