Welcome to Sparkpeople!
You CAN get that weight off. You are in the right place!
Being realistic is the first step forward in this journey. The nutrition and fitness trackers are so helpful. I think making your health a priority is a wonderful thing.
Poke around the site - try the exercise videos and demos, read the articles, try a few spark recipes, join a team or two of common interests/goals and read personal blogs. You can begin with one of mine: www.sparkpeople.com/mypage_public_journal_
Whatever you do - don't give up. The destination is not optional, the journey begins!
