eh, I am fine with judging people's soda consumption. That shit is bad for people. So are an awful lot of other things, many of which I indulge in, but one of the shittier aspects of sugary drinks is that our bodies just don't notice liquid calories, so unlike solid treats we have no way to instinctively moderate them.

My husband quit soda recently, after years of trying. He laid in a lot of his favourite bottled water and used a bunch of different kinds of low-calorie dissoluble tea granules to make the transition. He's since stopped bothering with the tea granules and just drinks water. I don't do sugary drinks at all myself (stopped during college to save money, never started again) but I am pretty damn bad about sweet treats. I DO find that the sugar craving goes away if I deliberately try to avoid it for a while but when I'm not on track for that, I keep sweet treats around that aren't going to do me much harm - dark chocolate I can just have a little square or two of, tictacs and sugar-free sours, raisins and fresh fruit.

There's a pretty good BMR calculator here.

also, excellent doctor blogger Yoni Friedhoff wrote an article about ignoring body fat percentage scales. YMMV.
