Use a photo with clothes on. Shirtless, swimwear or underwear photos are often blocked by the AI safety filter, and the simulation will fail. Fitted everyday clothes or gym wear work best.

Where do you carry most of your weight?

Real weight change isn't proportional — this stops the AI from shrinking your legs when it's your belly that changes.

What is AI Weight Loss Simulator?

AI Weight Loss Simulator is an online tool that uses artificial intelligence to visualize your weight loss goals. Upload a photo, set your target weight, and see a realistic before and after weight loss comparison instantly.

Unlike generic photo filters, our weight loss simulator with photo is designed to preserve your identity, lighting, and background while creating a believable preview of your possible transformation.

Why Choose Our Weight Loss Simulator

A photo-based AI weight loss simulator for fast, realistic transformation previews.

Still Looks Like You — No Funhouse Warping

Older simulators just pinch your cheeks narrower. Ours keeps your face, features, and expression intact and redistributes weight the way a real body changes — face, neck, arms, waist, and legs.

Find Your Goal Weight

Not sure if 20 or 30 lbs is your number? Run the same photo at −10, −20, −30, −40 and compare — most people are surprised where the visible change kicks in.

Full Body, Not Just a Face Filter

Upload a full-body photo and see the whole change, or a portrait for face and jawline only. Works for men and women, any body shape.

Save It as Your Lock Screen

Download an HD Before & After card and keep your goal in front of you every day. Photos are processed securely and deleted after generation — never used for training.

How It Works

Three simple steps to visualize your weight loss journey.

Upload Photo

Upload a clear photo of yourself — full-body or portrait, well-lit, in fitted clothing for best results.

Set Your Weight

Use the weight slider or type in how many pounds you want to lose (or gain). Supports both lbs and kg.

Weight Loss Simulator FAQ

Common questions about our AI weight loss simulator.

What is an AI weight loss simulator?

An AI weight loss simulator is a tool that uses artificial intelligence to show you what you'd look like after losing (or gaining) weight. Upload a photo, set your target weight change, and get a photorealistic before-and-after result.

Is the weight loss simulator free?

No. Each HD simulation uses 10 credits from a one-time credit pack — the $1.9 Starter pack covers one full-resolution result with no watermark, plus a Before & After card, and bigger packs let you try more targets. No subscription, and credits never expire.

How does the weight loss simulator with photo work?

Simply upload a clear photo of yourself. Our AI analyzes your body and generates a realistic simulation of what you'd look like at your target weight. Both full-body and portrait photos work.

How accurate is the weight loss simulation?

The AI keeps your identity — face, features, skin, clothing, and background — and changes only what weight loss or gain realistically changes: cheeks and jawline, neck, arms, waist, hips, and legs. It won't simply squeeze your photo narrower like older apps. Every body is different, so treat it as a realistic preview for motivation, not a medical prediction.

Is my photo data secure?

Yes. Your privacy is our top priority. Photos are securely processed and automatically deleted after generation. We never use your photos to train public models.

Can I simulate both weight loss and weight gain?

Yes! The weight slider supports both negative values (weight loss) and positive values (weight gain), ranging from -100 to +100 lbs/kg.

Can I try several target weights on the same photo?

Yes — that's the best way to use it. After your first result you'll see quick buttons for −10, −20, −30, −40 lbs. Many people find the weight where the change really shows is different from the number they had in mind. Each extra simulation costs 10 credits.

What kind of photo works best?

For best results, use a well-lit photo where your body is clearly visible. Avoid loose or baggy clothing. Both full-body and portrait photos are supported.

What would I look like if I lost weight?

Upload a photo and set a target such as −20 lbs: the simulator edits your own picture so you can see your face, neck, waist and body at that weight while you still look like you. As a rough guide, others notice weight loss in your face after about 8–9 lbs (a 1.33-point BMI change, per University of Toronto research), and around 10% of body weight most people look visibly leaner.

Is there an app that shows what you would look like if you lost weight?

Yes — this one runs in your browser, so there's nothing to install. Upload a photo, choose how many pounds or kilograms to lose or gain and where you carry weight, and compare a realistic before-and-after. Free 3D body visualizers also exist, but they show a generic body from your measurements rather than your own photo.

How is this different from a 3D body visualizer?

A 3D body visualizer builds an average body from your height and weight — it's free and needs no photo, but it doesn't look like you. This AI weight loss simulator edits your actual photo, keeping your face, hair, clothes and background, and removes fat where you tell it you carry weight.

Can I share my before and after results?

Of course! Download your weight loss simulation results and share them on social media, with your trainer, or with friends for accountability.
