When anyone first starts SW they tend to have a large weight loss the first week, why do you think this is? Most of it is probably water but what foods get rid of it that you eat when starting SW that you weren't eating before. I cann't say that my foods have changed much on SW other than I'm not eating fats, and the bread has been reduced. Obviously the treats have reduced but other than that food is pretty much the same, and I wouldn't have thought fats, bread and treats would have had the water retention factor to such an extent. Does anyone have any ideas on this.
