Artificial Intelligence Body Fat Percentage Calculator


Do you want to discover your body fat percentage from a picture you upload?

If so, you're in the right place. This calculator was built by analyzing pictures of 1000's of people at different body fat percentages using an A.I. classifier.

We built this calculator for ourselves as we wanted a quick and easy way to determine our own body fat percentage (with a picture taken in front of a mirror).

To our surprise, our friends wanted to use it too. So, we put it out in the world.

All you have to do is upload your picture like the one below and make sure it's just you in the picture.

Help Make Us Better

I hope you’ve received value from this web application and keep coming back to it to check your body fat percentage as you progress on your fat loss journey. As you might have read, to keep improving, the web app needs data.

A lot of data. Sadly, this is very hard to come by. However, there is a way you can help me if you’ve got a Dexa Scan done or plan on getting one in the future.

Here’s how you can help: If you can send me a picture of the upper half of your body, just like the one you uploaded to the web app along with your Dexa Scan results (visceral and subcutaneous fat percentages), that would help solve some of my data needs. I don't need to know your name or see your face. Your identity will be protected.

I know this is asking a lot, but if I can make this application even 20% better than what it is today, that is a 20% improvement in the lives of everyone using this application, including those who cannot afford to get a Dexa Scan.

If you can help out, please send the images and stats to
