How to Make Your Body Shape Slim with AI

Everyone wants to look great in a photo, especially those who are a bit fat. Your belly might be poking out, or your torso is not your best feature. These days, you don't have to exercise for a whole year to be slim and then take a photo. You can get a slim body version of yourself in a recently captured photo by using software and mobile apps, and the best part is that it all happens in a matter of moments. In this guide, you are going to learn all about it and how to hide fat-ish elements in your picture and achieve a look you feel comfortable with while looking at it or sharing it with others.

Part 1. How to Make the Body Slim with AI Using Luminar NEO

To adjust body proportions using AI and make it slim, Luminar NEO's Body AI tool simplifies the entire process into a few key sliders and tools. Here's a complete guide to help you through every step using the exact features inside Luminar NEO.

Step 1. Access the Body AI Tool

Download and install the Luminar NEO software on your PC, open it, and click + to upload your photo. As soon as you upload it, select it and click Edit to land in the Edit Module.

In the Edit module, go to the Portrait section under Tools. You'll see Body AI listed alongside other portrait tools like Skin, Face, and Portrait Bokeh. Click on Body AI to begin.

Step 2. Adjust the Shape Slider

The first slider under Body AI is called Shape. This directly affects the width of the subject's torso. When you slide it to the right, it makes the subject slimmer, and sliding it to the left adds more volume. To clearly see the difference, push the slider all the way to each end. This gives a proper view of how the change appears in real-time on your photo. As you are targeting the slim effect, slide to the right till you achieve the look you want.

If you want to revert to the original, just double-click on the slider name to reset it.

Step 3. Use the Abdomen Slider

Next comes the Abdomen slider. This pinches the subject's abdomen to remove visible bulk. Again, slide fully in the right direction to make it slim.

The abdomen adjustment targets the midsection specifically and is useful when refining the look of the body after using the Shape slider. Both sliders can be used together for stronger results.

Step 4. Refine with Face AI

Once you're done with the body, scroll to Face AI in the Portrait section. Here, there's a Slim Face option. This lets you narrow the face width so it aligns better with the slimmed torso and abdomen.

Apply small adjustments with the slider and watch how it complements the earlier edits. You can reset this as well with a double-click if needed.

Step 5. Apply to Group Photos

You can also apply Body AI edits to photos with more than one person. To do this, import a couple or group image into the Edit Module. Open Body AI and use the Shape slider. This affects all visible subjects. For example, slimming both individuals at once works well when both benefit from the adjustment. Then try the Abdomen slider-this may apply more effectively to one person than the other, depending on body positioning. Use the Slim Face slider next, though it might affect some faces more noticeably than others.

Step 6. Use the Masking Tool for Targeted Edits

When Body AI or Face AI edits impact all subjects in the image, you can use Masking to focus the adjustments on one person. Doing this is quite simple.

After finishing edits with Body AI or Face AI, both of these tools move to the Edits tab at the top, next to Tools.

Click Edits and click on the tool you just used, such as Body AI, and hit Add Mask.

Choose Paint Mask, select the brush tool, and adjust its size. Then, paint directly over the subject by clicking on where you want to apply the effect on only one subject. The AI tool's effect will now appear only on the selected individual. Repeat the same steps with the Face AI tool if needed.

Step 7. Review Before and After

To compare the results, use the Before/After toggle in the Edits tab.

This allows you to evaluate how the Shape, Abdomen, and Face edits work together. If something doesn't look quite right, go back to any tool in the Edits tab and fine-tune the sliders.

By combining Body AI, Face AI, and the Masking tool inside Luminar NEO, you can slim your body and face, and selectively apply changes. This setup gives flexibility for single portraits or multi-subject photos.

Part 2. How to Apply the AI Slim Body Effect In the CapCut App

CapCut includes a built-in Slim tool inside the Retouch section that adjusts body proportions in your selfies using a simple slider. Here's a step-by-step walkthrough.

Step 1. Open CapCut and Start a Project

In the first step, just open the CapCut app on your phone and tap Edit from the main screen.

From there, select a photo or video from your gallery. The project then loads into your timeline.

Step 2. Navigate to the Retouch Section

Once the image appears in your editing space, tap on Edit at the bottom. After that, swipe left through the available tools until you reach Retouch.

This section includes body and face adjustment options that are applied directly to the selected image.

Step 3. Tap on the Body Option

Inside Retouch, go ahead and select the Body tool. A set of body-shaping features appears, including the Slim effect you're aiming to use.

Step 4. Apply the Slim Effect

Now just tap on the Slim button. You'll see a slider at the bottom. Moving it to the right narrows the body shape in the image, and you'll notice the changes as soon as you slide. The adjustment updates in real time while you're dragging the slider across.

Step 5. Save Your Changes

Once the edit is done, simply tap the check mark icon in the bottom-right corner. That confirms the adjustment and brings you back to the main screen, where you can continue working on other parts of the photo if needed. For example, you can also slim your face when you tap Retouch below the timeline menu.

Part 3. How to Use the Slim Body AI Filter Using the PowerDirector App

A skinny generator can give a quick idea of body transformation, and PhotoDirector's AI Replace feature offers a direct way to try it on your photo. Here's how to use it step by step.

Step 1. Download and Install the PhotoDirector App

To get started, just install the PhotoDirector app on your phone. It's available for free in both the Android and iOS app stores.

Once installed, you'll be ready to explore the AI-based tools it includes.

Step 2. Open AI Replace and Upload Your Photo

Once the app is set up, open it and go to the AI Replace option. After selecting it, choose a photo from your gallery that you want to edit. The tool loads the image and prepares it for the next steps.

Step 3. Brush Over the Body Area

There's a brush tool in there that you can use to select the marked parts of the body that you want to be slim.

This can be around the waist, arms, legs, or the full body, depending on the changes you're going for. The effect applies only to the area that's been brushed.

Step 4. Enter a Prompt

Now type in a simple prompt such as "slim body" or "weight loss effect." This tells the tool exactly what kind of transformation is expected from the edit. The AI uses the prompt to generate changes based on the selected body areas.

The tool processes the image in just a few moments and shows a new version based on your prompt. The result offers a slim body version of the original photo using the adjustments applied through AI Replace.
