I have to admit that I am still a skeptic on this one. There has been some research that suggests that "consuming dairy products helps with weight loss when coupled with calorie restriction," (emphasis mine) but the researcher who found that link was funded by the dairy industry. Here are some more links suggesting that any weight loss benefit has been overstated.
Because 70% of the world's population, like me, is lactose intolerant, I really wonder if human beings were meant to have all of this dairy. Tolerance for milk among northern Europeans (and people descended from them) is the gift of a mutation common in the milk-drinking world. Besides the lactose issue, I am concerned about artificial hormones administered to cows to increase their milk production. Even if it is safe for humans, it does not seem to be very good for the cows. It's easy to find milk that is organic and free of artificial hormones, but my favorite yogurt, Fage, doesn't make any claims to be free of the stuff. The only organic Greek yogurt I've found so far, Oikos, is very sour and not at all to my taste. Left to my own devices, I'd have one serving of dairy products every day or two.
So I'm ambivalent about the whole dairy products thing. Last week's weight-loss success convinced me to keep up the GHG compliance for a while, but I'm still not totally convinced. I often wonder if Weight Watchers gets lobbied by various industries and companies to promote certain food products on the program, the way the USDA was when it redesigned the food pyramid to its current useless graphic.
I'm enjoying my cheese (mostly fresh mozzarella) and yogurt for now, but I'm still thinking that I may up on the other side of this one.
