if you're no longer logging your food intake, you might want to go back to that for awhile and see if it helps. I quit logging my food and weighing myself for about a month when I was in India last year (well, I didn't have access to a scale, so...). I wasn't eating like a pig or anything, but I came home a few lbs heavier than when I left. Through that I learned I have to monitor myself pretty much all the time, or my weight will start heading north. Although I know different things work for different people...(my dietitian hates the fact I count calories and weigh myself so much, but hey...whatever works. And that's been working for me for the past several years, so...)
