You've got a great foundation. Take your time to explore all that Spark People has to offer you. Choose a few things to work on like using the nutrition and fitness trackers. Join a couple of Spark Teams that reflect your goals, interests, hobbies, whatever. Give and get lots of support. Rule # 1 Enjoy the journey!
Congrats on getting active with SparkPeople - it's a great community, wonderful resources and fantastic support- it's also lots of fun and easy to make friends because we're all in this together. I can totally understand your dilemma but you aren't the first or only one in your predicament - I don't know if you watch The Biggest Loser but they have had several contestants recently who owned gyms or wellness centers, often have professional athletes and others who have plenty of know-how but didn't use it. Heck, I think most of us here have enough 'dieting' and 'nutrition' and 'fitness' knowledge to fill a book - but it's the DOING that counts, as you know!
Sometimes the best way to start is to just pick a small goal such as drinking 8 glasses of water a day or eating 5 fruits and veggies plus a small exercise goal such as increasing whatever you've been doing by 10% - the 20 minutes you spent on the elliptical is a great example of that!!
I like the way a HEALTHY LIFESTYLE is emphasized here instead of a 'quick fix wonder diet' and another nice thing about SparkPeople is that we have permission to be human - we don't have to change everything at once or be in a hurry to reach our goals. Take a few baby steps and then a few more and before you know it, you'll have completed a long journey - I hope you enjoy this community as much as I have - it teaches us how to make positive lifetime changes because that's the only thing that will work over time!
Please check out SparkTeams - you can choose them by age group, lifestyle or interests, geographic location, common goals such as a certain weight loss or several other ways. I'd also like to invite you to join the Virtual Walk/Run/Cycle Thru the US @ exercise.lbl.gov SparkTeam - it's a really fun way to track your walking while you travel 'virtually' across America from Virginia to Oregon. Go to the SparkTeam page at www.sparkpeople.com/myspark/groups_i ndividual.asp?gid=19805 for more information.
