If you are going to pick one to work on -- WATER. By far VERY important to your weight loss.

My number 2 pick would be exercise but it's a weak #2. If you can get out for an extra short walk or two during the week or take the stairs instead of an elevator, great -- that's exercise. A lot of people don't exercise and do well while some people have to in order to loose weight. I would think though, when you are closer to goal it's going to become more important to get exercise. Right now -- ehhh. if you are loosing without it and you REALLY don't want to do it -- it's your choice. Don't beat yourself up over it.

#3 Coffee. I still drink 2-3 cups a day and I'm fine. It seems most people are. There are some unlucky ones out there who stall from coffee though. Again, if you are loosing while drinking it -- don't worry.

In summary: Drink lots of WATER and don't sweat the other stuff too much.
