Maintaining 150 lb as a lightly active male means 2,168 cal daily: 128g protein, 279g carbs, 60g fat. These numbers match your 2,166 TDEE exactly, with protein weighted to hold 123 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 | 150 lbs |
|---|---|
| Estimated Lean Mass | 123 lbs (82% of body weight) |
| Lean Mass (kg) | 55.8 kg |
| BMR (Katch-McArdle) | 1,575 cal/day |
| TDEE (BMR x 1.375) | 2,166 cal/day |
| Target Calories | 2,168 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 | 128g | 512 | 24% |
| Carbohydrates | 279g | 1116 | 51% |
| Fat | 60g | 540 | 25% |
| Total | - | 2,168 | 100% |
Protein is set at 2.3g per kg of lean body mass (123 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 2168 cal precisely.
Plan 3 meals that total 2168 calories
Divide daily calories evenly: roughly 723 cal per meal for a 150 lb man. Each meal targets about 43g protein, 93g carbs, and 20g fat.
Hit 128g protein first
Protein is the lock, carbs and fat are the flex. 128g across 3 meals is 43g 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 70g of your 279g carbs in the meal 1-2 hours pre-workout and 84g 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 150 lb man holding 2168 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 128g 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 150 lb man, train to preserve or slowly build lean mass. Pre-workout, 70g of your 279g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 84g 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 128g protein target from becoming wasted at 2168 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 2166 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 150 lb man on 2168 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 8 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 150 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 2166 TDEE, which turns 2168 into 2068+ effective cal within a year. Lift 3 times a week minimum at 128g protein daily.
Frequently Asked Questions
Why is protein 128g for maintenance at 150 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 150 lb man with 123 lbs of lean mass needs 128g 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 2168 calories?
At 2168 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 60g for a maintenance diet?
Fat is set at 25% of total calories, which is 540 calories or 60g 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 128g of protein across meals?
Across 3 meals, each meal needs about 43g of protein. Across 5 meals or snacks, each needs about 26g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 43g per meal in 3 meals is within the optimal 30-40g range.
What are 279g of carbs used for in a maintenance diet?
The 279g of carbs provides 1116 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 279g of carbs fuels daily activity at a sustainable level without gain or loss.
Should I recalculate my macros as I track weight?
At maintenance, recalculate your TDEE every 4-8 weeks if your weight shifts more than 5 lbs consistently. Lean mass changes affect calorie needs.
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 150 lbs.
