Questions, answered
What is a weight loss simulator?
It's a tool that simulates what your body would look like after losing weight. Most online simulators make you fiddle with sliders on a generic 3D dummy. BodyTimeline runs the simulation on your actual photo instead — the AI reads your real face, frame and proportions and renders a believable slimmer version of you, so the result looks like you and not a cartoon avatar.
How do I run the simulation?
Upload one clear photo and the AI does the rest — no sliders, no measurements, no goal weight to type in. In a few seconds it returns your simulated result: the leaner version of you after 90 days of real effort, alongside the path you're on if nothing changes.
Is the weight loss simulator free?
Yes — your first simulation is free. Upload a photo and you'll see your result in seconds, no payment to run it.
How realistic is the simulation?
It's a realistic, motivational visualization built from your real photo — not a medical prediction or a guaranteed outcome. Think of it as a skilled artist showing you a believable version of yourself lighter, to make the goal feel real and worth chasing.
Is my photo private?
Your photo is used only to run your simulation. We don't post it or share it publicly, and it auto-deletes.
