For the most part changes come slowly, a pound here, an inch there. Because it is such a slow process it's easy to throw in the towel or give up. But over time a pound here and an inch there add up to a big change.
I've only lost a couple of pounds and a couple of inches so far this challenge, I don't see or feel any big changes...but I'm 1 pound away from hitting the 30 lb. loss mark since starting the first challenge...and that seems like a big milestone.
I guess I'm just saying stick with it! All of these little changes you're making will add up!
