Weight loss before & after, generated from one photo
This is exactly what BodyTimeline produces: a realistic 90-day transformation timeline built from a single photo. Below are real example renders from the tool — day 0 to day 90. Then make your own.
A 90-day timeline, from one selfie
The same person, rendered at four points across 90 days. This is the core of what you unlock — your body, at the finish line, in stages.
Day 0
Day 30
Day 60
Day 90And the same four stages for a second subject — the renders are built from whoever is in the photo.

Generate my transformationQuestions, answered
Are these real weight loss before and after photos?
No — and we say so plainly. Every image on this page is an AI-generated visualization produced by BodyTimeline to show exactly what the tool renders from a single uploaded photo. They are realistic motivational previews, not real patients and not a medical prediction.
How does the AI before and after work?
You upload one clear, front-facing photo. The AI reads your real frame, face and proportions and renders a 90-day transformation timeline that looks like you — day 0, day 30, day 60 and day 90 — plus the worst-case version of staying on your current path.
Can I make my own before and after like these?
The preview is free: upload one photo, add your email, and you get a first preview and your projected numbers in seconds. The full results (your slimmer self with your face, all 12 renders and the 90-day plan) are a one-time unlock, no subscription.
Does this work for Ozempic, Mounjaro or natural weight loss?
The visualization is the same regardless of method — it previews what your body looks like at a lighter weight. Whether you're losing weight on a GLP-1 like Ozempic or Wegovy, or through diet and training, the 90-day timeline shows the destination.
Is my photo private?
Your photo is used only to generate your result. We don't post it or share it publicly, and it auto-deletes.
