For me, the only way Dr. Ede's numbers would be worth it is if I get a cancer diagnosis. As part of a comprehensive treatment plan I think it is totally doable, as an experiment on losing weight I think it is too extreme, at least for me!
I have not started the blood monitor yet. I will do it on Monday morning, as well as all my measurements, including the BF% from my regular scale (it can do it but is a pain in the butt). That way if the DEX I get actually does BF too, I will have comparison numbers. I will do the blood monitor on Monday mornings through March. In April, when the college visits are done I will start daily. The ketostix don't seem to work for me either.
No, I don't have to do the DEX scan often. The last bone scan was several years ago, not sure if it was a DEX or not though. When I have to get the next one will be determined by the results of this one.
