Hey jp, congrats on being proactive and taking charge of your situation. I lost almost 60 lbs two years ago by simply eating healthy and it was easier than I thought. If you can teach yourself to eat strictly for health and not pleasure you'll be home-free. I think that's the biggest hurdle for most dieters. I have no experience with the app, but if it works for you then stick with it.

Best of luck and keep us posted of you progress
