You are motivating me to lose more weight. I've been walking 4 to 5 miles a day in a building while conducting training classes, moving back and forth down the halls. I've lost a few pounds but not enough. My walking is not sustained, so that is the problem.
I am perhaps unique in that I rarely gain weight on a cruise. I actually eat more healthy foods while on a ship since they are available, and I don't have to prepare them.
