Welcome!
First of all congratulations on the changes you've made and on all the weight you've lost. It's
very difficult to keep the weight off, and the fact that you've caught it now and want to get it back under control is amazing.
There's a Men's Corner under Support Groups that you might like to chat with other guys around the site. There's also a 20-something's area.
People might be able to give you some advice if you let everyone know what you're doing now. Food plans or exercise plans. Anything of that sort.
Best of luck!
