What are your goals? You say you want to maintain your current weight, well, how long have you been your current weight? Are you slowly losing or gaining weight?
Are you exercising heavilty and maybe need more protein? Are you not exercising alot and maybe need more fat? Carbs aren't evil, but how much you take really does depend on how much you exercise and what kind of exercise you do.
For example, I want to put on mass. So I LHT five times a week, and am eating about 50% protein, 35% fat, and 15% carb (all from vegetables - yes, I like tomatoes). This is not appropriate for someone who isn't looking to add muscle mass. So maybe 50% fat, 35% protein and 15% carbs. If you are an endurance athlete, however, then you'd likely want a larger % of carbs.
So tell us about your needs and what you do
