Questions, answered
How does the weight loss before and after generator work?
Upload one clear photo and BodyTimeline's AI builds your own before-and-after: your body as it is now next to a realistic preview of it after 90 days of real effort. Because it's generated from your actual photo, the 'after' looks like you — not a stock model or someone else's transformation.
Is the before and after generator free?
Yes. Your first before-and-after preview is free — no payment to see what's possible. Just upload one photo and your result comes back in seconds.
Is the 'after' image realistic?
The AI works from your real frame, face and starting point, so the 'after' is a realistic, motivational projection rather than a fantasy. It's a visualization to keep you going, not a medical prediction.
Do I need two photos for a before and after?
No — that's the point. You only need one photo of yourself today. The generator creates the 'after' for you, so you can see the transformation before you've even started.
Is my photo private?
Your photo is used only to generate your result. We don't post it or share it publicly.
