Recomp Macro Calculator
What Is Body Recomposition
Body recomposition, usually shortened to recomp, is the process of losing fat and gaining muscle at the same time, so that body composition improves even if total body weight changes little. Traditional advice separates the two goals, with a calorie surplus for muscle gain and a deficit for fat loss, but research and coaching experience show that beginners, people returning after a break, and people with higher body fat can often achieve both at once, especially with adequate protein and progressive resistance training. Recomp is slower than a dedicated cut or bulk, but it avoids the extremes of either and suits people who want to look leaner and get stronger without dramatic weight swings.
Nutrition is the lever that makes recomp possible, and protein is the most important part of it. A high protein intake supplies the building blocks for muscle repair while helping to preserve fullness, which makes it easier to stay near maintenance calories. Fat intake supports hormones and vitamin absorption, and carbohydrate fills the remaining calories and fuels training performance. The Recomp Macro Calculator on this page turns those principles into daily gram targets from two inputs, body weight and training days per week, so the plan is concrete rather than vague advice to eat more protein.
It is worth stating the limits plainly. A macro calculator gives a starting point, not a prescription, and individual needs vary with age, sex, training history, sleep, stress, and medical conditions. The targets here are educational, and anyone with a medical condition, a history of disordered eating, or a specific performance goal should discuss nutrition with a clinician or registered dietitian before following any plan.
How the Macro Targets Are Set
The calculator sets protein at one gram per pound of body weight per day, which is a widely used recomp figure that sits comfortably within the range most sports nutrition guidance recommends for active people. For a 180-pound person, that is 180 grams of protein per day. Fat is set at 0.35 grams per pound, which gives 63 grams for the same person, enough to support hormone health without crowding out carbohydrate. Calories are set from body weight multiplied by an activity factor, 13 for three or fewer training days, 14 for four or five days, and 15 for six or seven days, reflecting the extra energy cost of frequent training.
Carbohydrate is whatever remains after protein and fat are accounted for. Protein provides 4 calories per gram and fat provides 9, so for the 180-pound person training four days a week, calories are 180 times 14, which is 2520, protein accounts for 180 times 4, which is 720 calories, and fat accounts for 63 times 9, which is 567 calories. Subtracting gives 1233 calories for carbohydrate, and dividing by 4 gives 308 grams. The same arithmetic produces every result the calculator shows, so the targets always add up to the stated calorie total, subject to rounding to whole grams.
Rounding deserves a brief note, because macro targets that do not sum exactly can look like an error. The calculator rounds fat and carbohydrate to whole grams, which can move the implied calorie total by a few calories either way. That difference is nutritionally meaningless, and tracking to the nearest ten calories is more than precise enough for recomp, where weekly trends matter far more than any single day.
How to Use This Calculator
Enter your body weight in pounds and select your training days per week, then press Calculate. The result panel shows daily calories, protein, fat, and carbohydrate targets. Use those targets as a daily framework, not as a rigid prescription, and distribute protein across three to five meals where possible, since spreading protein through the day supports muscle repair better than eating most of it in one meal.
Track for at least two weeks before judging the plan. Weigh yourself a few times a week under consistent conditions, take progress photos monthly, and note training performance, since strength gains at a stable weight are a strong sign that recomp is working. If weight is climbing steadily and waist measurements are rising, reduce carbohydrate by 25 to 50 grams. If weight is falling fast and strength is dropping, add a similar amount. Small adjustments every two to four weeks beat large swings.
Worked Example
Take a 180-pound person training four days a week. The activity factor is 14, so calories are 180 times 14, which is 2520. Protein is 180 grams, fat is 180 times 0.35, which is 63 grams, and carbohydrate is 2520 minus 720 minus 567, divided by 4, which is 308 grams. The daily targets are therefore 2520 calories with 180 grams of protein, 63 grams of fat, and 308 grams of carbohydrate, and those figures match the calculator exactly.
A second example shows a lighter, less frequent trainer. For 150 pounds and three training days, the factor is 13, so calories are 150 times 13, which is 1950. Protein is 150 grams, fat is 150 times 0.35, which rounds to 53 grams, and carbohydrate is 1950 minus 600 minus 477, divided by 4, which is 218 grams. The contrast with the first example shows how both weight and training frequency move the targets, which is why copying another person’s macros rarely works well.
Adjusting Over Time
Recomp plans need periodic adjustment because the body adapts. As you gain muscle and lose fat, maintenance calories shift, training loads increase, and the original targets gradually become less accurate. A practical rhythm is to reassess every four weeks, comparing weight trend, waist trend, and gym performance. If all three are moving the right way, change nothing. If weight is stable but strength is climbing and the waist is shrinking, the plan is working even though the scale is quiet, which is common in recomp and should be celebrated rather than fixed.
Plateaus are also normal. After several weeks of progress, fat loss often slows while muscle gain continues, or vice versa. Before changing calories, check the basics, which are sleep, protein consistency, and training progression, since a week of poor sleep or missed sessions explains many stalls. If the basics are solid and progress has stalled for three weeks, adjust carbohydrate by 25 to 50 grams in the direction that matches the goal, then wait another two weeks before judging again.
Common Mistakes
The most common mistake is eating too little, on the theory that a bigger deficit means faster fat loss. In recomp, an aggressive deficit undermines muscle gain, increases hunger, and often leads to muscle loss alongside fat loss, which defeats the purpose. A second mistake is under-eating protein while hitting the calorie target with carbohydrate and fat, which leaves training without the raw material for repair. A third mistake is changing targets daily based on scale noise, since body weight fluctuates with water, glycogen, and gut contents by several pounds within a week.
A fourth mistake is neglecting training progression. Macros support muscle gain, but only progressive resistance training signals the body to build muscle in the first place. A perfect diet without a programme that gradually increases load, volume, or difficulty will maintain muscle at best. Pair the macro targets with a structured programme, track the weights lifted, and aim to improve something most weeks, whether load, reps, or technique.
A Sample Day of Eating
Macro targets become much easier to follow when they are translated into a sample day, because abstract gram figures do not tell you what to put on a plate. For the 180-pound person training four days a week, with targets of 2520 calories, 180 grams of protein, 63 grams of fat, and 308 grams of carbohydrate, a workable day might start with Greek yoghurt, oats, and berries at breakfast, providing roughly 40 grams of protein and 80 grams of carbohydrate. Lunch could be a chicken and rice bowl with vegetables, adding about 50 grams of protein and 90 grams of carbohydrate, while a pre-training snack of a banana and a protein shake adds 25 grams of protein and 40 grams of carbohydrate without much fat.
Dinner is where the remaining protein usually lands, for example salmon or lean beef with potatoes and a large serving of vegetables, contributing roughly 50 grams of protein, 70 grams of carbohydrate, and a good share of the daily fat through the fish or cooking oil. An evening snack of cottage cheese or a casein shake adds a final 15 grams of protein with little carbohydrate or fat, bringing the day close to the targets without any meal feeling extreme. The exact foods matter less than the pattern, which is protein at every meal, carbohydrate concentrated around training, and fat kept moderate throughout.
For the 150-pound person on 1950 calories with 150 grams of protein, 53 grams of fat, and 218 grams of carbohydrate, the same structure works at smaller portions. Breakfast might be eggs on toast with fruit, lunch a turkey wrap with salad, and dinner chicken with rice and vegetables, with a protein shake covering any shortfall. The point of the sample is not to prescribe a menu but to show that the targets correspond to ordinary meals rather than exotic foods or constant weighing, and that hitting protein at each meal is the habit that makes the rest fall into place.
Drinks and cooking methods deserve attention, because they are where hidden calories usually enter. Cooking oil adds about 120 calories per tablespoon, sugary drinks add carbohydrate without fullness, and alcohol adds calories while impairing recovery and sleep. None of these need to be eliminated, but counting them honestly for a week usually reveals whether the plan is genuinely being followed or whether the targets are being met on paper while extras push the true intake well above them.
- Breakfast: protein-rich base such as yoghurt, eggs, or a shake, plus oats or fruit.
- Lunch: a palm-sized protein portion with rice, potatoes, or bread and vegetables.
- Pre-training snack: easily digested carbohydrate with a modest protein portion.
- Dinner: the largest protein portion of the day with vegetables and a carbohydrate source.
- Evening snack: a slow-digesting protein such as cottage cheese if protein is short.
Sleep is the most underestimated part of any recomposition plan, because it affects hunger hormones, recovery, and training performance at the same time. Short sleep raises appetite and cravings, reduces the proportion of weight lost as fat, and impairs strength in the gym, which means a perfect macro plan can stall on poor sleep alone. Aiming for seven to nine hours, keeping a consistent wake time, and limiting screens and alcohol before bed are unglamorous steps, but they often unlock progress that extra dietary restriction cannot, and they cost nothing.
Frequently Asked Questions
What is body recomposition?
Body recomposition, or recomp, is losing fat and gaining muscle at the same time, so body composition improves even if total weight changes little. It works best for beginners, returning trainees, and people with higher body fat, combined with adequate protein and progressive resistance training.
How much protein do I need for recomp?
This calculator uses one gram of protein per pound of body weight per day, a widely used recomp figure. For a 180-pound person that is 180 grams daily, spread across meals, which supports muscle repair while preserving fullness near maintenance calories.
How are recomp calories calculated?
Calories are body weight multiplied by an activity factor: 13 for three or fewer training days, 14 for four or five days, and 15 for six or seven days. The factor reflects the extra energy cost of frequent training, and the result is a near-maintenance starting point.
How are carbs calculated?
Carbohydrate fills the calories remaining after protein and fat. Protein provides 4 calories per gram and fat 9, so carbs equal calories minus protein calories minus fat calories, divided by 4. The calculator rounds to whole grams.
Why is fat set at 0.35 grams per pound?
Fat at 0.35 grams per pound is enough to support hormone health and vitamin absorption without crowding out carbohydrate needed for training. For a 180-pound person that is 63 grams of fat per day.
How long does recomp take?
Recomp is slower than a dedicated cut or bulk, with visible changes typically taking eight to twelve weeks or more. Progress shows as a shrinking waist, stable or slowly changing weight, and improving gym performance, rather than rapid scale movement.
Should I track macros every day?
Daily tracking for at least two weeks builds awareness of portion sizes and protein distribution. After that, many people track loosely or only on training days, as long as weight, waist, and strength trends stay on course.
What if my weight does not change?
Stable weight with a shrinking waist and rising strength is a classic sign that recomp is working, since fat loss and muscle gain are offsetting on the scale. Judge progress from photos, measurements, and performance, not from weight alone.
Can advanced lifters recomp?
Advanced lifters with low body fat and years of training find recomp much harder, since they are closer to their muscular potential. For them, dedicated gaining and cutting phases usually produce faster results than attempting both at once.
Do I need supplements?
No supplement is required for recomp. A varied diet can supply the protein and micronutrients needed, and protein powder is simply a convenient food. Discuss any supplement, including creatine, with a clinician if you have a medical condition.
How do I adjust if I stall?
Check sleep, protein consistency, and training progression first, since those explain many stalls. If progress has stalled for three weeks with basics solid, adjust carbohydrate by 25 to 50 grams in the direction matching your goal, then wait two weeks.
Is recomp safe?
For healthy adults, recomp through balanced nutrition and resistance training is generally safe. Anyone with a medical condition, a history of disordered eating, or a specific health goal should discuss the plan with a clinician or registered dietitian first.
Should training days include cardio?
The training day count here refers mainly to resistance training sessions, since those drive muscle gain. Cardio can be added for health and fat loss, but heavy cardio increases calorie needs, so mention it when adjusting targets.
What about rest days?
Macro targets here are daily averages, so the same targets apply on rest days for simplicity. Some people prefer higher carbs on training days and lower carbs on rest days, which averages out to the same weekly totals if done consistently.
Is my data stored?
No. The calculation happens in your browser when you press Calculate, and nothing is sent or stored. You can close the page immediately after seeing the result.
