If you wanted to be a part of the study, but wanted to start addressing your weight and body image issues by not weighing as Robin suggested in her book and her vlogs, I don't mind if you weigh and take your body fat percent only weekly. However, I do suggest you stick to the original protocol if choosing to do this, because my hunch is that certain modifications CAN cause significant muscle loss, and the idea is to catch this right away so you can have the most fat loss possible.
