a couple of sites I've recently found: 

http://www.traineo.com/ - nice design and useful articles

http://sparkpeople.com/ - been around for ages diet/weight loss community.

 

yikes

Newsflash! Researchers have found the “fat” gene! Overweight people are predisposed to gaining weight in much the same way that kids born to brunette parents are likely to have, gasp!, brown hair.

I didn't realise Diet.com were posting vids on youtube! boot camp style workout - good stuff!

 

Please comment on this post with any suggestions for improvements / changes to the site - all ideas appreciated!

Weightlossweek.com is a community for anyone interested in health, diet, and weight loss.

 

The site allows you to create your own community around any specific topic you wish - for instance you could set up your own community for a local weight watchers meeting, or a local running club, or a general support network....or anything - it's up to you :)
