Feeling like that little girl in the "Willy Wonka" movie? I don't know but that has happened to me. I gained 6 or more pounds in 3 days after the holidays and it wasn't water weight because its taken me over a month to lose it. I believe the fat cells just lay there empty and as soon as you eat high carb food, they fill up in an instance. I just know if I go back to eating a regular diet, I'll gain all this weight back. Now for you maybe some is water weight and weighing late in the day rather than first thing, I easily add pounds during the day. My lowest weight is first thing in the morning.
