Sometimes this stuff just doesn't make sense to me. As much as you exercise and as clean as you eat, crankin, it makes no sense that you are gaining weight. Even though you are still light, I know you feel the same as me at 108 -- not a happy camper! 
You don't think that paradoxically you might not be eating enough and your body is going into starvation mode, do you? I know I've read/heard that sometimes eating a bit more can help in weight loss, even though it's hard to believe!
I, on the other hand, was at my lowest weight in a long time this morning, and there's no rhyme nor reason about it, but I'll take it, of course. I weighed 4-5 lbs. more when I was running regularly than I weigh now, and I'm not eating very differently. I did cut out my daily fruit smoothie in the afternoon (an extra "meal" I didn't need), but that was months ago. In my case I think some of it may be hormonal since I am in the peri-menopausal fluctuation time. I did add two bike rides to my weekly workout, but it's hard to imagine that making this much of a difference in my weight-maintenance efforts. If it's that, then good!
I suspect I'm going to be putting on a few lbs. soon as we'll be leaving Belize in either March or April (depending on whether the sale of our condo goes through or not), and towards the end we'll be going out to eat a lot more -- got to hit all our favorites one last time. And in the US too, I'm sure we'll be eating out a lot at first. So better to start a little lower if I can maintain now.
