the weight training is building muscle.  muscle is heavier than fat.  The fat you are losing is being replaced by muscle. The muscle is smaller that the fat you are losing, so you could be losing inches but not pounds.

thanks...but im still 50 lbs. overweight...wouldnt i have to lose this fat before anything else.or am i building muscle underneath this fat...

You  probably need to lower your calorie intake a little because the muscle does weight a lot more than the fat hince you are building muscle that out weighs the fat you are losing. Or cut back on the exercise a little.
