Everyone is Different.....
FitnessC -
I'm also new to this board, like you, but have been working out for years (including being a personal trainer)!
Everyone here is right, even though it seems so backwards .... that you have to eat MORE to lose weight! But it's so ahrd to say exactly what will work because everyone is different - different metabolisms, different workouts, different ideas of what is considered a "hard" workout, etc.
The program you are using to calculate your BMR is an ESTIMATED number. It doesn't know you from me from spatts from anyone else. I imagine it is taking your height, weight, age, and plugging the numbers into a formula. Well, your gentics might not fit that formula. Learning what works for you is through trial and error, we all have had to do it. It is a pain - and takes months, if not years, to figure out YOUR best food/exercise ratio. The only thing you can do is change one thing at a time and see what that does for you (and give it 4-6 weeks to see changes) and keep modifying from there.
Forgive me, I can't remember if you mentioned this, but how long have you been training? It does take time - about 4 weeks to lose 1% of BF (for the average person). So be patient!
THAT SAID.....It seems like you do need to add a little more food - maybe one more meal of a protein, complex carb and some fat. As far as more protein, in order to lose BF and gain muscle, estimate about 1g of protein for each lg of body weight. And for carbs, the more complex the better, the less starchy the better. In general, I think it is better to go for lower Glycemic Index carbs.
Not sure this made any sense, I do tend to babble....
