Wow, normal BMI... Hi five!! WTG!!
I saw this come up on facebook and think it's so helpful!
You may not be able to weigh or measure your portions, but if you keep this in mind, you ought to be able to keep from over eating too often. And then plan to maintain, if not lose.
I went on a trip once and wanted to keep myself in check. Since the daily weigh for me is an integral part in keeping myself accountable, I didn't want to be a week without a scale. My first stop was Walgreens to buy a cheap scale to keep in the hotel room. My next trip, I didn't go out and buy a scale, but when I found a scale in the house we rented, I used it!
What RandomPaige wrote about using the gym, if you have access to one, there's another way to off set vacation damage.
But remember how much relaxing can help a diet along too! Have fun!
BTW, my last trip, even though it included bad food, plenty of alcohol and not enough exercise, I still managed to lose a pound. It's possible!
