11 months ago, I purchased the course as a Christmas gift to myself. Never regretted the investment in my own health. I have lost and kept off 60+ since 12-26-20. Thank you Dr Boz for your easy to follow and clear information. You are truly gifted in your teaching style and honest approach to better health. I still have a little way to go, but have no doubt I will continue to improve one Ketone at a time!
