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.

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 can happen at different calorie intakes.
Body recomposition means losing fat and gaining muscle over the same period. It does not require a calorie deficit. Training, protein, recovery and your starting point affect the response. No calorie target guarantees both changes.
The energy window
Use estimated maintenance as a reference. A deficit can prioritize fat loss; maintenance or a slight surplus may support training and growth, with less predictable fat loss. Review waist, weight, strength and recovery over several weeks.
Illustrative starting intakes, not a proven recomposition range.
Protein is the floor
About 1.6 to 2.2 g of protein per kg of body weight daily can support muscle retention and growth alongside resistance training.
Training is the signal
Progressive resistance training supports muscle retention and growth. Choose a routine you can recover from and advance over time.
Choose a starting intake. Train and eat enough protein. Adjust from your response.

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 means losing fat and gaining muscle over the same period. A deficit is optional. Progressive resistance training, adequate protein, recovery and your starting point affect the result. No calorie target guarantees both changes.
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.
