How it works

  1. Upload your photo

    Upload a clear photo showing the area you want to edit. Good lighting and sharp focus help the AI deliver better weight loss results. JPG, PNG, WebP up to 7MB.

    Expect: Moderate weight loss visualization: 30-45 seconds. Dramatic transformations: 45-60 seconds and may need refinements.

  2. Describe the weight loss goal

    Type what you want: 'show this person 30 pounds lighter' or 'visualize a slimmer version with a toned midsection.' Be specific about the degree of change and any target areas. No marking needed—the AI adjusts proportions across the entire body.

    Tip: Reference specific changes like 'slimmer waist', 'less belly', or 'defined jawline' for more targeted visualization.

    Copy one of these to get started:

    General weight loss preview show what this person would look like 30 pounds lighter, natural and proportional reduction across the body
    Try This →
    Slimmer midsection focus visualize this person with a slimmer midsection and reduced belly, keep everything else proportional
    Try This →
    Toned and fit look show a toned and fit version of this person, leaner with visible muscle definition
    Try This →
    Moderate gradual change show this person about 15 pounds lighter, subtle and realistic change
    Try This →
    3 more prompts
    Face slimming included visualize weight loss across the whole body including a slimmer face and more defined jawline
    Try This →
    Athletic transformation show this person transformed to an athletic build, less body fat with broader shoulders and toned arms
    Try This →
    Healthy weight range show this person at a healthy average weight, natural-looking with balanced proportions
    Try This →

  3. Review the visualization

    Check that the result looks like a realistic version of the person at a lower weight. Look for natural body proportions, proper clothing fit, and consistent face features. The person should still be recognizable.

  4. Refine with markers if needed

    If specific areas need more or less adjustment, tap markers on those spots and regenerate. Most moderate weight loss visualizations look realistic on the first try.

    Tip: Markers are for precision refinement only. Try without them first—you usually won't need them.

Detailed Guides by Scenario

📷

Design Visualization

Preview weight loss changes on your actual photo before committing — make confident design decisions backed by visuals.

Common Scenarios

  • Simulating weight loss on a room, outfit, or space to evaluate the look
  • Creating client-ready mockups that visualize weight loss in their specific context
  • Comparing multiple weight loss options side by side using the same source photo

Best Practices

  • Upload a clear, well-lit photo from the angle you'd naturally view the subject
  • Be specific about the weight loss — color, material, size, and placement all matter
  • Generate 2-3 variations to have meaningful options to compare
📷

Professional Proposals

Win client approval with realistic weight loss previews that show exactly what the finished result will look like.

Common Scenarios

  • Building a presentation deck with weight loss visualizations for a client pitch
  • Showing stakeholders weight loss options before ordering materials or starting work
  • Creating before-and-after comparisons of weight loss for a project proposal

Best Practices

  • Use the client's own photos for the most persuasive previews
  • Label each option clearly (Option A, B, C) for easy discussion
  • Note that weight loss previews are approximations — set expectations about final results
📷

Personal Decision-Making

Try before you buy — preview weight loss on your own photos to make smarter purchasing and lifestyle decisions.

Common Scenarios

  • Previewing weight loss before making an expensive purchase
  • Testing how weight loss looks in your actual space or on your actual person
  • Sharing weight loss previews with family or friends to get opinions before deciding

Best Practices

  • Upload a photo of the actual space/item/person — generic stock images won't help you decide
  • Try the most different options first (bold vs. subtle) to narrow down your weight loss preference
  • Save each preview so you can flip between them when comparing

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which area to adjust from description alone. It may have changed the face or other features along with the body.

Try: Tap a marker on the body area to adjust, then regenerate: slim this area only, keep face and features the same
Try This →

Tip: Markers tell the AI 'I mean THIS area specifically.' Use them when you want to target the body without changing the face.

Person doesn't look like themselves anymore

Why: Aggressive weight loss visualization changed too many features at once, making the person unrecognizable.

Try: show a subtle weight loss of about 15 pounds, keep the same face and body structure, just slimmer
Try This →

Tip: Start with smaller changes and increase gradually. 'Keep the same face' is critical for recognizability.

Clothing looks wrong after body changes

Why: The AI slimmed the body but didn't properly adjust how the clothing fits on the smaller frame.

Try: visualize weight loss and adjust the clothing to fit naturally on the slimmer body, realistic draping
Try This →

Tip: Fitted clothing makes the change more visible and easier for the AI to adjust realistically.

Result looks too thin or unhealthy

Why: Without a specific target, the AI may over-correct and produce an unrealistically thin result.

Try: show this person at a healthy weight, natural-looking with balanced proportions, not too thin
Try This →

Tip: 'Healthy weight' and 'not too thin' set upper and lower bounds for the AI's adjustment.

Background is warped near the body edges

Why: Body reshaping can distort background pixels adjacent to the changed areas.

Try: visualize weight loss while keeping all background elements clean and undistorted
Try This →

Tip: Photos against simple backgrounds (plain walls, solid colors) produce the cleanest results.

Quick answers

Do I need to mark my body before describing the weight loss?

No! Just describe the goal: 'show this person 30 pounds lighter' or 'visualize a slimmer midsection.' The AI adjusts proportions automatically across the body. Only use markers if you want to target a specific area and the AI is changing the wrong parts.
