I tried for 750-850 calories per day, while still getting a balance of nutrients. And the exercise was hard.. not sitting on a stationary bike reading a book while pedaling. I sweated off the pounds while re-building leg muscles that hadn't been used in three years because of bad knees, (an Osteopath fixed them for me before I began,) and regaining cardio and stamina. Stair climbing several times a day. I live on the 6th floor. Never used the lift. Speed-walking up steep hills. I mean I really, really pushed... From 103kg to 89kg. And tomorrow we leave to go paragliding. Perhaps this time the small Japanese parachutes will keep me up a little longer!
(I confess to hearing the theme song from "Rocky" in my head when I reached the top of the mountains...)
