When going through your set up, you will be greeted with a prompt to ask what your body fat percentage. This is ultimately to help gauge lean mass and protein needs. If you are not 100% accurate on your selection this will not make a large or meaningful difference in your success! Do not stress it that much. Simply select the option where the photo most closely aligns with what you look like at the moment. It is likely not the best idea to use a body fat value that you see on a home scale as these can be rather inaccurate. Gauging based on the photos would likely be a more accurate assessment.
