I've been sticking more closely to the McDougall diet even though I'm not trying to follow it strictly anymore; I just feel better the more lowfat whole vegan foods I eat. I haven't managed to avoid stepping on the scale despite knowing that the information it provides is only of limited use. As of today I weigh 138 pounds, well on my way to my Feb 1 goal of 135 and ultimate goal of 125. I just started using a cute diet ticker in my signatures on the McDougall discussion board.
I also found through that message board a cool open-source program called CRON-O-Meter which provides comprehensive tracking of nutrients through USDA data. I'm not monitoring carbs/protein/fat, but it's useful to see how I'm doing on vitamins and minerals, since I don't take any supplements other than B12 (and occasional extra Vitamin C when I'm sick). If the source numbers and my reporting for the last couple of days are accurate, I've been eating fewer than 1200 calories a day, but not feeling hungry or deprived, despite getting over 30 minutes of aerobic exercise each day as well. I'm also drinking a lot more water, partially because of the warm weather, which helps.
