I must be doing something right! Today I weighed 142.2, down from 146 last week. I've been very good about my exercise goal, so no doubt that helps, but I can't believe I paid no attention to food whatsoever--I remember having a Snickers at work on Friday, because I was severely disappointed with my lunch, and on Saturday having some of the greasiest Quiche Lorraine I've ever eaten.
Usually when I first start exercising my weight goes up--I think maybe because of muscle soreness or something, or maybe even a little muscle building. It must be the intervals!
