http://www.facebook.com/WeightOffMyShouldersBlog If you are concerned about privacy, keep in mind that you are in control. Share what you want to share, nothing more.
Once you are on Twitter, be active! Tweet every day about your workouts, recommend healthy recipes, join fitness challenges (see PlankADay for an example) or just tweet your thoughts about your journey that day. Interact with other tweeters too, congratulate them on their successes, comment on their tweets, and don’t be shy! I guarantee within a few weeks you will have some regular Twitter weight loss buddies.
Blogs – A blog is an online journal that is viewable to the public. Go to www.blogger.com to set one up (for free!), then compose and post entries about your process. What to write? Anything you want. Tweet and/or post your blog entries on your Facebook page to share them with others. This is a great way to engage others in your journey. Why blog? For yourself. Do it to express your thoughts, challenges and/or lessons learned. It can take a while but over time you will get readers and commenters. Here are a few awesome blogs to check out to give you an idea: http://the-running-mom.com/ , http://letstalkandwalk.com/ , and http://www.whoatemyblog.com/.
Online communities – Sparkpeople, Weight Watchers, and Livestrong are three websites that have online communities (i.e., discussion boards) in which you can interact with other people trying to lose weight. Check out these websites and start interacting in the communities.
If you are missing a strong social support system for your weight loss effort, consider that this may be holding you back from success more than you think. Instead of giving the next trendy diet a try, consider taking your weight loss journey into cyberspace. Success may be just a few follows, friends, and likes away. I'll see you online!
