I was diagnosed stage 3 four years ago next month. In warm weather, I bike 5-10 miles six days a week and go to the gym. In cooler weather, I do 30 minutes of cardio and 20-:30 minutes of weightlifting. I enjoy heavy food and, occasionally, food that is not so good for me. I would guess that I live a better than average lifestyle: I will be eighty-four in a few days. My doctors say I will not do from PBC.
Be of good cheer!
