I actually gained weight, surprisingly. I'm 5'3" and weighed in somewhere around 106 or 107 pounds before the trip, and now I weigh 109.5. (Just enough to finally donate blood, I hope.) The other women on the trip kept a pretty constant weight, though I think I am the only one who actually gained weight. One guy started out around 260 pounds and lost at least 16.

I didn't lose any weight from training, probably because I didn't train enough.
