Consider getting DEXA scans to track your progress

They are a scan that is often used for gone density, but can also be extremely accurate for your body composition, fat vs muscle and show you where it is located. Over time you will be able see if the weight you are loosing is fat or muscle.

Prices can vary a lot, most places seem to want over $100 per scan, but I finally tracked down one that brings it into the $40-$50 range. https://www.bodyspec.com/pricing Does seem like they are limited to LA, San Francisco, Seattle, Dallas and Austin areas though.

Also, please share if you know of other well priced options in those or other areas to help people out.
