So what's your weight now?
And yeah I did get similar things. For instance, I went to Vegas this summer and ate like a pig. Got up to maybe 162-163 pounds at the worst and then back down to 154 within a week.
Like I said, when you're losing weight, you don't eat a lot so your scale weight is always 1-3 pounds under your normal maintenance weight and when you pig out, it goes up by a LOT depending on what you ate / drank and it can stay around for a couple days. So from the under-evaluated weight to the over-evaluated one, there's a huge difference that is basically all due to food/water retention and not fat.
