This new website showed me what I would look like if I worked out - and who my celebrity body double is

Bodywhat is a new website that tells you not only your body fat percentage, but how sexy it thinks you are, along with who your celebrity body double is - all from a single photo. It can even show you an estimate of what you would look like if you worked out more, or if you completely let yourself go.

Here's how it works. You simply upload a picture - high quality, straight on. Stop flexing.

Bodywhat does the rest of the work, 3D modeling your body and comparing it to its database to extrapolate different metrics about your body. It works by comparing different data points in your picture to a reference set of thousands of others.

Needless to say, I was both skeptical and apprehensive about trying out the service. Did I want to know the news if it was bad? I decided to take the plunge. Come with me as I go down the body scrutiny rabbit hole with the aid of machine learning.
