Recomposition is a loop, not a single number.
Body recomposition is not solved by a static calorie target or a generic meal plan. Losing fat while gaining muscle takes a loop: log what you eat, measure the trend, review what moved, and adjust the smallest thing that matters. Recomp AI is the agent that runs that loop with you.
- 01LogMeals, weight, and training in seconds.
- 02MeasureCalories, protein, and a weekly weight trend.
- 03ReviewWhat changed, and whether the deficit is real.
- 04AdjustThe smallest useful change to calories or protein.
Tell it your goal. It builds the system around you.
Recomp AI turns plain requests into working nutrition surfaces. These run today. More of the agent is on the way.
“Log a meal from a photo, barcode, voice, or label”
Say "log this" with a photo. The agent fills in macros and a clean entry you can edit.
Fat loss and muscle gain overlap in a narrow window.
Recomposition is fat loss and muscle gain at once, and it lives in a narrow band around maintenance. A small deficit for most people, maintenance for advanced lifters who are already lean, even a slight surplus for lean beginners with real training. Where you land depends on how much muscle you have left to gain and how much fat you carry.
The energy window
A small deficit for most, maintenance for advanced and lean lifters, even a slight surplus for lean beginners. Recomposition lives in this narrow band, not at a single number.
Protein is the floor
1.6 to 2.2 g per kg of bodyweight, locked in before anything else. It tells the body to keep muscle and pull from fat.
Training is the signal
Progressive resistance, three to four times a week. Without it, a deficit takes muscle and fat together.

Recomp AI in plain answers.
Recomp AI is an AI nutrition app for body recomposition. You tell the agent your goal and log your meals and weight by photo, barcode, voice, or text. It sets your calorie and protein targets, tracks your weight trend, and reviews your week to keep fat loss and muscle gain moving at the same time.
Body recomposition is losing fat and gaining muscle at the same time. It needs three things in parallel: enough protein to build muscle, calories near maintenance or in a small deficit, and progressive resistance training. Recomp AI is built to keep those signals in range week after week.
You log meals and weight. The app computes your intake, protein, and a moving-average weight trend, then compares them against targets from your stats and goal. When the trend drifts, the agent proposes the smallest useful change to calories or protein and explains why in a sentence or two.
Snap a photo, scan a barcode, paste a label, or just say what you ate. The agent fills in macros, a portion estimate, and a clean entry you can edit. Logging a meal takes a few seconds.
People who want to change their body composition, not just their scale weight. Beginners losing fat without losing muscle, intermediate lifters cycling between phases, and anyone returning to training after a break. If you only want to count calories, a generic tracker is fine. If you want fat down and lean mass holding or rising, this is the tool.
No. The calculators for BMI, BMR, TDEE, macros, protein, lean body mass, body fat, weight-loss pace, water intake, and waist ratios run in your browser without an account. They use the same formulas as the app, so your numbers stay consistent if you download it later.
