Cutting at 170 lb as an extra active female on the Gentle (15%) deficit works out to 2,613 cal daily: 133g protein, 356g carbs, 73g fat. The 462 cal pull against your 3,075 TDEE targets about 0.9 lbs per week of fat loss while protecting 128 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 | 170 lbs |
|---|---|
| Estimated Lean Mass | 128 lbs (75% of body weight) |
| Lean Mass (kg) | 57.8 kg |
| BMR (Katch-McArdle) | 1,618 cal/day |
| TDEE (BMR x 1.9) | 3,075 cal/day |
| Target Calories | 2,613 cal/day |
| Daily Deficit | 462 cal/day (20% deficit) |
| Expected Weekly Change | 0.92 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 25% average body fat for women. Activity multiplier 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 133g | 532 | 20% |
| Carbohydrates | 356g | 1424 | 55% |
| Fat | 73g | 657 | 25% |
| Total | - | 2,613 | 100% |
Protein is set at 2.3g per kg of lean body mass (128 lbs lean mass for this woman), scaled to the 15% deficit. 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 2613 cal precisely.
Plan 3 meals that total 2613 calories
Divide daily calories evenly: roughly 871 cal per meal for a 170 lb woman. Each meal targets about 44g protein, 119g carbs, and 24g fat.
Hit 133g protein first
Protein is the lock, carbs and fat are the flex. 133g across 3 meals is 44g 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 89g of your 356g carbs in the meal 1-2 hours pre-workout and 107g 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 44g to 33g 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 170 lb woman cutting at 2613 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 170 lb woman on 2613 cal. Of your 356g daily carbs, put 89g in a meal 1 to 2 hours pre-workout (rice, oats, or a piece of fruit) and 107g in the meal within 2 hours after. This preserves training quality on a 462-cal deficit and replenishes muscle glycogen when it matters. The remaining 160g spread across other meals. Protein post-workout is less time-sensitive than the industry suggests: a 30g to 40g feeding (of your 133g 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 extra active rating (1.9x) assumes very hard exercise and physical job, not a gym session 3 times a week. Third, weekend blowouts: two 1,500-cal social meals can cancel 5 days of 2613-cal adherence for a 170 lb woman. Track weekends the same as weekdays.
Frequently Asked Questions
What are 356g of carbs used for in a cutting diet?
The 356g of carbs provides 1424 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 356g, 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 170 lb woman cutting to 155 lbs, the TDEE shifts by roughly 209 calories and macros should be recalculated.
What foods hit 133g protein, 73g fat, and 356g carbs?
Protein sources for 133g: roughly 4 x 100g portions of chicken breast (31g protein each), or 22 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 73g: about 5 tablespoons of olive oil or peanut butter. Carb sources for 356g: roughly 8 cups of cooked rice (45g each) or 13 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
How does my activity level affect my 2613 calorie target?
Your Extra Active activity level uses a multiplier of 1.9, giving a TDEE of 3075 calories. If you were sedentary (1.2x), your TDEE would be approximately 1942 calories. If you were very active (1.725x), it would be approximately 2791 calories. The activity multiplier is the single biggest variable in your calorie target. Getting it right matters more than small differences in the macro split.
What should I do if I'm not losing weight at 2613 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Try reducing by 100-150 calories first. If energy drops significantly, check your protein intake before cutting calories further. Common issue: overestimating activity level.
How long should I stay in a cutting phase at 2613 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 2613 calories, a 170 lb woman should lose approximately 0.92 lbs per week. After 10-12 weeks, take a 4-8 week maintenance break to reset ghrelin and cortisol before cutting again.
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 1.9x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 170 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 170 lbs when you weigh less will slow progress.
