Hi Amanda and welcome to 3FC!
I have not used the Beachbody products but you may find some others who have here -

For tracking my food/drink intake and exercise, I use sparkpeople.com and I love it
My main advice is to get on a plan, stay focused, stay determined, stay committed and remember that only YOU control if YOU succeed or fail.
Good luck with your goals
Hugs
Michelle
