Cutting at 150 lb as a lightly active male on the Very Aggressive (40%) deficit works out to 1,299 cal daily: 173g protein, 55g carbs, 43g fat. The 867 cal pull against your 2,166 TDEE targets about 1.7 lbs per week of fat loss while protecting 123 lbs of lean mass. Lean tissue, not total weight, is what sets BMR, so preserving it is priority one. Fix protein first. Flex carbs and fat around training load. Track pinch checks, waist circumference, and morning weight weekly rather than daily. Adherence matters more than micro-adjustments: hitting these macros 6 of 7 days beats hitting them perfectly 3 of 7 with two cheat days.

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 | 1,299 cal/day |
| Daily Deficit | 867 cal/day (20% deficit) |
| Expected Weekly Change | 1.73 lbs loss per week |
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.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 173g | 692 | 53% |
| Carbohydrates | 55g | 220 | 17% |
| Fat | 43g | 387 | 30% |
| Total | - | 1,299 | 100% |
Protein is set at 3.1g per kg of lean body mass (123 lbs lean mass for this man), scaled to the 40% deficit. Fat targets 30% 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 1299 cal precisely.
Plan 3 meals that total 1299 calories
Divide daily calories evenly: roughly 433 cal per meal for a 150 lb man. Each meal targets about 58g protein, 18g carbs, and 14g fat.
Hit 173g protein first
Protein is the lock, carbs and fat are the flex. 173g across 3 meals is 58g 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 14g of your 55g carbs in the meal 1-2 hours pre-workout and 17g in the post-workout meal. Spread fat evenly across remaining meals. Carb timing matters for training quality on a deficit.
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 weight has not dropped in 2 weeks, cut 100 cal from carbs. Going faster than 1.5 lbs/week? Add 100 cal. Never adjust on a single day's reading.
What This Looks Like In Practice
Meal timing and structure
On a cut, eat 3 to 4 meals with 58g to 43g of protein each. Space them 4 to 5 hours apart to keep hunger manageable. Front-load your day with protein and fiber at breakfast (eggs, Greek yogurt, berries) to stabilize blood sugar and reduce afternoon cravings. A 150 lb man cutting at 1299 cal has limited room for mistakes, so skipping meals and overeating later is the most common failure mode. Keep a 30g protein snack available for evenings.
Training day nutrition
Time carbs around training for a 150 lb man on 1299 cal. Of your 55g daily carbs, put 14g in a meal 1 to 2 hours pre-workout (rice, oats, or a piece of fruit) and 17g in the meal within 2 hours after. This preserves training quality on a 867-cal deficit and replenishes muscle glycogen when it matters. The remaining 24g spread across other meals. Protein post-workout is less time-sensitive than the industry suggests: a 30g to 40g feeding (of your 173g daily target) within 4 hours of training is the window.
Common pitfalls to avoid
Three pitfalls kill most cuts. First, underreporting food intake: cooking oils, dressings, and "tastes while cooking" commonly add 200 to 400 uncounted calories a day, which can wipe out the entire deficit. Weigh food for 2 weeks to calibrate. Second, overestimating activity: a lightly active rating (1.375x) assumes light exercise 1-3 days per week, not a gym session 3 times a week. Third, weekend blowouts: two 1,500-cal social meals can cancel 5 days of 1299-cal adherence for a 150 lb man. Track weekends the same as weekdays.
Frequently Asked Questions
How much weight will I lose at 1299 calories?
At 1299 calories per day, a 150 lb man should lose approximately 1.73 lbs per week. This assumes a TDEE of 2166 at lightly active activity and a deficit of 867 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 43g for a cutting diet?
Fat is set at 30% of total calories, which is 387 calories or 43g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Cutting fat scales 25% to 30% of calories with deficit size in Andrew Menechian's framework, biased upward at aggressive deficits to protect hormonal function. 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 173g of protein across meals?
Across 3 meals, each meal needs about 58g of protein. Across 5 meals or snacks, each needs about 35g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 58g per meal in 3 meals is within the optimal 30-40g range.
What are 55g of carbs used for in a cutting diet?
The 55g of carbs provides 220 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a cut, carbs fill the remaining calories after protein and fat. At 55g, this is a moderate-carb cut, not a low-carb diet.
Should I recalculate my macros as I lose weight?
Yes. Recalculate every 10-15 lbs of weight loss. As your weight changes, lean mass, BMR, and TDEE all shift. For a 150 lb man cutting to 135 lbs, the TDEE shifts by roughly 166 calories and macros should be recalculated.
What foods hit 173g protein, 43g fat, and 55g carbs?
Protein sources for 173g: roughly 6 x 100g portions of chicken breast (31g protein each), or 29 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 43g: about 3 tablespoons of olive oil or peanut butter. Carb sources for 55g: roughly 1 cups of cooked rice (45g each) or 2 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
When to Recalculate These Macros
Not losing weight after 2 consistent weeks
Reduce by 100-150 cal/day, pulling from carbs first. Your actual TDEE may be slightly below the 1.375x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 150 lbs, faster loss increases muscle loss risk and energy crashes. The target rate is 0.5-1 lb per week on a cut.
Lost 10 or more lbs from this starting weight
Recalculate at your new weight. BMR and TDEE drop as you lose mass. Eating the macros for 150 lbs when you weigh less will slow progress.
