Body Recomp Calculator

It estimates a starting calorie and macro target for body recomposition. You enter body stats, an optional body-fat estimate, activity, lifting experience, lifting days, and a goal emphasis. The calculator returns estimated TDEE, average calories, training/rest-day targets, protein, fat, carbs, a recomp viability category, and a realistic 12-week projection. It's a starting point, not a meal plan — and it doesn't track food.

Yes, but not equally for everyone. Recomp is most realistic for new lifters, returning lifters, people with more body fat to lose, and lifters who haven't trained consistently with progressive overload. Trained lifters can still recomp, but the rate is slower and expectations need to be tighter. The common pattern is a small calorie deficit or maintenance, high protein, and resistance training that progresses over time.

Not always. Recomp is useful when you want to improve body composition without a hard scale-weight goal. Cutting is usually better when fat loss is clearly the main bottleneck. Lean bulking is usually better when you're already lean and need more muscle. Recomp sits in the middle: slower, less dramatic, but often easier to sustain if you care about both waist and strength.

Use the training/rest split if it helps you fuel lifting days and stay consistent. The split gives more calories and carbs on training days and fewer on rest days while preserving the same weekly average. Use the same daily target if your schedule is chaotic, adherence is easier with one number, or cycling makes you overthink. The weekly average matters more than the split.

Most lifters should be somewhere around 1.6–2.2 g/kg bodyweight, with higher relative targets useful during a deficit or when using lean-mass-based math. This calculator sets protein from lean mass when body fat is available, then applies a bodyweight floor and cap. The practical goal is simple: high enough to support training and lean-mass retention, but not so high that carbs and fats become impossible.

You can use the calculator without body-fat percentage, but the result is less specific. Without body fat, the calculator uses Mifflin-St Jeor for BMR and hides the body-fat-based viability score. With body fat, it can estimate lean mass, use Katch-McArdle, set protein from lean mass, and warn very lean users away from aggressive deficits. Your estimate doesn't need to be perfect — it needs to be honest.

Because fat loss and lean-mass gain push scale weight in opposite directions. You can lose fat, gain some lean mass, store more glycogen from better training, and see very little scale movement. Judge recomp with multiple signals: weekly average weight, waist, photos, training performance, and how clothes fit. If nothing changes for 4–6 weeks, then adjust.

Expect months, not weeks. A useful first checkpoint is 8–12 weeks. Beginners and returning lifters may see faster changes; advanced lifters should expect slower progress and smaller visual changes. The calculator shows a 12-week projection because that's long enough to collect a real signal without pretending recomp is instant.

If you're a male under about 12% body fat or a female under about 18%, don't treat aggressive fat loss as the default. You may still improve body composition, but recovery and performance become bigger constraints. Maintenance or a small surplus usually makes more sense than trying to force fat loss and muscle gain at the same time.

A fat-loss-led recomp can make sense. The goal isn't to bulk. Use a small-to-moderate deficit, keep protein high, and train hard enough to preserve strength. If body weight and waist are dropping while strength is mostly stable or improving, the plan is doing its job. If you have medical conditions, medications, or a history of disordered eating, use professional guidance instead of relying on a calculator.

No. Stronger is a gym tracker, not a nutrition app. This website calculator gives a nutrition starting point because that's what the body recomp search intent requires. Inside Stronger, the focus is training: logging lifts, tracking progressive overload, Strength Score, and muscle-group benchmarks. Don't expect meal logging, macro tracking, or calorie coaching in the app.

Use trends, not one bad day. If waist and scale trend aren't moving and strength is fine, reduce average calories by about 100–200 kcal. If strength is falling hard, recovery is poor, and hunger is high, raise calories or move from fat-loss-led to balanced. If scale weight is climbing quickly and waist is rising, lower calories. Make one change at a time.

Yes. The calculator uses the female Mifflin-St Jeor coefficient and female body-fat thresholds for viability warnings. The general principles are the same: small deficit or maintenance, high protein, progressive resistance training, and enough recovery. Menstrual cycle changes can affect scale weight, water retention, hunger, and performance, so women should rely more on multi-week trends than daily weigh-ins.

Cardio can help, but it isn't the main signal for muscle retention or gain. Use it for health, conditioning, and extra energy expenditure if you can recover from it. Don't add so much cardio that your lifting performance collapses. For recomp, resistance training is the anchor; cardio is optional support.

Carbs are calculated last. The calculator sets calories, then protein, then a fat floor. Whatever calories remain become carbs. If your calorie target is high, carbs may look high. If your target is aggressive, carbs may look low. That doesn't mean carbs are good or bad — they're the flexible macro after protein and fat are covered.
