Real Body Fat says it estimates body-fat percentage from a full-body photo, then discards the image rather than storing it. Founder Divyanshu Singh describes the service as a small web app built around that constraint: a photo scan, a vision model, and persistent credit balances without a conventional user database. Those are the founder’s and service’s claims—not findings from an independent security audit or validation study.
What the photo scan does
The service asks for a front-facing, full-body photo plus age, height, and weight. It says it returns estimated body-fat percentage, lean mass, and fat mass in roughly ten seconds. These are estimates, not direct measurements of body composition.
How to take a usable photo
Real Body Fat recommends fitted clothing, even lighting, standing six to ten feet from the camera, and holding the arms slightly away from the sides. These conditions may help the model assess the visible body consistently, but they do not make the result a clinical measurement.

Singh describes an Astro frontend running on Cloudflare Workers, with a React island handling the scan. According to his account, the image passes through a Worker to a vision model and is not persisted at either end. He says the system does not write the photo to disk or use it for training.

Instead of a conventional account database, the service uses Durable Objects to persist credit-wallet balances. Singh says the wallet flow was the more difficult implementation problem: casual users receive a free daily scan, and additional scans can be bought as one-time credits that do not expire. The product page currently lists credit packs starting at $5; pricing and scan limits can change.
The service’s privacy page also says photos are not stored or seen by a person. These statements describe the founder’s implementation and the service’s published policy. They do not independently establish how every provider, log, configuration, or runtime behaves; the deployment and its data path have not been independently audited in the materials available.

What the result can—and cannot—tell you
Real Body Fat presents its output as directional, not as a medical or clinical reading. The service does not publish a single accuracy figure, and no independent validation of this particular photo model is established in the reviewed material. Singh says the estimate is weakest for very lean or very muscular bodies. A photo-based estimate should not be treated as equivalent to DEXA or another clinical baseline.
Lighting, posture, clothing, and individual fat distribution can all affect photo-based estimates. Real Body Fat’s own guidance is to choose one method and watch the trend over weeks rather than rely on any single result. As Singh put it in a September 13, 2026 build article: “The move I recommend is to pick one method and track the trend over weeks, not to trust any single reading.”

Photo scan or tape measure?
If you would rather not upload a photo, the site offers a free U.S. Navy circumference calculator. It uses height, neck, and waist measurements, so you will need a measuring tape. The photo scan involves less measuring; the tape method avoids image upload and can be repeated under consistent measuring conditions. Neither method turns an estimate into a clinical assessment.
| Method | Inputs | Useful for | Limit |
|---|---|---|---|
| Photo estimate | Full-body photo, age, height, and weight | A quick, directional estimate without tape measurements | Image-based estimate; the service publishes no single accuracy figure |
| U.S. Navy calculator | Height, neck, and waist measurements | A non-photo alternative that can be repeated with consistent technique | Requires careful circumference measurements and remains an estimate |
| DEXA | A scan appointment | A more precise clinical or one-off baseline, as described by the service | Not the same low-effort, at-home process as either calculator |
Who this design is for
The one-photo approach may suit someone seeking a quick fitness-tracking reference who is comfortable using a photo-based estimate and accepts the service’s stated privacy policy. Someone who does not want to upload a photo can use the tape-based calculator instead. If the goal is a clinical baseline, the site itself points to DEXA rather than presenting its photo result as a substitute.
