There is always a risk of losing some muscle while dieting and it can end up being a highly individual thing as far as what works best for you but generally speaking, make sure you dont drop cals too drastically. Keep your protein intake where it is and gradually reduce your carb and/or fat intake (especially later in the day). Continue training with weights to keep your muscles stimulated and you should be able to hang onto what muscle you have while dropping B/F levels. Throwing in a higher calorie day once every 7-10 days is a trick some people use to keep their metabolism from slowing down.

good luck!
