Sparkpeople

I'm turnng 40 in just 3 months.  I've been telling everyone that I plan on being in the best shape of my life by then.  I found a great FREE site that creates diet and exercise plans to help you reach your goals.  Anyway, here's the official info on the site:

SparkPeople.com

The primary site, SparkPeople.com offers a free four-stage SparkDiet program which uses tools, content, and support to help users make lifestyle changes. Users are prompted to enter height, weight, and amount they intend to exercise, as well as a target date and weight. The site then gives recommendations for calorie, fat, and carbohydrate intake based on calculated BMR, as well as a personalized fitness plan. Users can enter the foods they eat and exercises they complete and are given feedback via charts and prompts on their progress. The site also has numerous articles on nutrition, fitness, motivation, and general health. Support is provided through other users and SparkPeople experts on messageboards as well as from social networking features like member pages (SparkPages), teams (SparkTeams) of users with some common bond (like quilting or college students), and blogs.

SparkPeople.com was named the winner of BusinessWeek's Best of The Web : Health in 2006 and 2007

In January 2007, SparkPeople.com was ranked by Hitwise as the 6th most visited site in the "Health and Medical - Wellbeing" category (and 3rd among diet sites)
