I'm not sure it really has a place in the primary application unless you want to use one of the 15 spots for your "hobbies" which could include working out and exercising. You could briefly mention the amount of weight that you lost.
But I agree with what others have said about it being a good topic to add into some secondary essays. It is clearly something that was a large accomplishment for you. I remember a couple of different secondaries which ask about non-academic accomplishments.
Adversity can be anything challenging that took hard work and/or determination in order to overcome. Regardless of how the OP gained the weight in the first place, it certainly took a drastic lifestyle change and a heck of a lot of determination in order to overcome it. Many people never make that change due to an array of challenging circumstances. That is something that should absolutely be included in the application and could be relevant down the road in his or her experiences with patients.
OP, I think include it wherever you feel most comfortable. I think keeping it in your pocket for secondary essays and to answer questions during interviews is probably your best bet. But, its really up to you.
