what is your overall goal? are you trying to lose weight?
diet is key when going on any fitness regime - i think your calorie count is off a bit and/or the calories you're getting arent good ones.
based on your weight your calorie intake per day should be around 1600 for your body to maintain weight at rest. if your count is accurate there is no reason why you're not dropping pounds.
i find even for myself that its pretty tough sometimes to drop to my competition weight. my pre comp diet is usually very low carbs. morning is a isolate protein shake, lunch chicken salad (water base dressing) dinner steamed veggies and chicken again. portions are small as well. drink LOTS of water. and to be honest - i dont hit alot of cardio either - just diet and weight training.
