Hi Jo and welcome to Spark People. This site will help you to learn how to live healthier. We do not believe in crash diets. Under the My Trackers tab at the top of the page you will find a nutrition tracker that will set you a calorie range based upon your input. There is also a fitness tracker available under this same tab. Also available on this site are healthy recipes, support teams, health articles, and much more. On the lower right of this page is a Quick Links block. Inside it you will find a getting started guide that will assist you in learning to use the site.
