I do not fast, exercise is an afterthought, although I am now the proud owner of a Fitbit and I am determined to use it. I am 79, 1 month away from 80. I have lost on the blue but not nearly as mush as the purple. I feel now more like a life style than a diet. took me a year to gain that insight. I have 20 more pounds to go according to my MD, but I think I can persuade him to 10. he is a little skinny guy. I feel so much better, off my BP meds. you can do it, but make it your journey, not someone else's
