I am currently fairly buff and really fit. I am 5'9" and 165lbs. I don't know my body fat percentage, but I look good with a tiny bit of blubber around the middle that you don't see unless i lean forward. I want to look leaner and more ripped. The goal is to lose body fat without losing muscle. I think my workout regiment is perfect, but I need help on diet. I lift in the mornings 6 days a week and I do cardio in the evenings. I already take protien shakes that total 675 calories per day giving 150 grams of protien (whey/casien blend). I need lots of complex carbs to support this activity level, but how many calories should they be adding up to per day?
