Lifting weights and eating right but gaining weight?!

Dunc1123

Hey, so Im an ex college softball player, who due to a back injury, lived a very sedentary life style for a year and am now probably 40 to 50a lbs over weight. I started following the south beach diet and was seeing.g good results, but I've started lifting again it since I read that weight lifting is best to burn fat (I mix 4 sessions of cardiovascular with 4the sessions of lifting. However I've noticed the scale starting to go up! My back dr told me it'd be best to get down to 24% body fat and im currently 32%....I've been lifting for 2a weeks now and feeling a little down about the weight gain considering I drink lots of water and follow all the rules! Any help or advice is welcome!
