Not new, but haven's said hi

Hello everyone. I'm not terribly new to the site. But after gaining back all 7 lbs that I lost in November I figured it was better to slowly lose than to only eat oatmeal for a month...ya know? Anyway, wish me luck!
Any tips for people who don't have much to lose, but can't get their body to drop any no matter the amount of exercie/eating?
