Hi, Welcome to Spark People.
You have come to the right place. This is not just about dieting, it is about life style change and finding support from positive people. Check out the Fitness Tracker and Nutrition Tracker features. These are powerful tools to help you get on track and stay on track. Try blogging, too. It is amazing the support you get from others who are struggling with similar issues or who have overcome them.
Jump in, join some teams, and be kind to yourself. Change doesn't happen over night, but it does happen.
BTW, I am 62. I love life... age is what you make it out to be. Once you become active, healthier, and more energized, 52 will just be a number. Don't let a mere number get you down.
Welcome to the new you!
