When I first had my brain injury, I had little coordination or balance and I still managed to get "exercise" in by (essentially) vigorously moving whatever I could move and flopping around. I'm sure I looked awful! But it got my heart rate up and made me sweat. I also did not overeat. Because I knew, deep down, that whatever problems I was having right then, being fat could only make them worse. Whitney will not lose weight simply because her fat has become her identity. Without her fat, what does she have, who is she? Nobody really impressive or worthy of notice.
