Kaitie, I think it is definitely chips possibly in conjunction with lean cuisine. Salty foods make you retain water, that's probably why you did not see any weight loss last week. See how much sodium is in lean cuisine dinners, but I would guess probably much more then in homecooked stuff you eat. Also some people tend to loose weight in chunks, and that's just the way some bodies operate. When stuff like this happens to me, I just attribute it to miriads of complex processes that happen on a daily basis and move on. Sometimes it is possible to explain the water retention, and sometimes it is not. We just cannot know everything that is going on inside and causes one thing or the other.
