How do I use the fat AI filter online?

Does the fat filter predict real weight gain?

No. It creates a novelty image and cannot predict body composition, where a person would gain weight or how a real physical change would look.

Does the fat face filter change the whole photo?

The intended effect focuses on visible face and body shape, but generative edits can also change clothing, lighting, background or facial details.

What photos work best with the fat filter?

Use a clear, front-facing image that includes the head, neck and the part of the body you expect the filter to reinterpret.
