The Zone and Tony Horton's Power 90 program both suggest a 40-30-30 ratio. 40% carbs, 30% protein, and 30% fat. I tried this for awhile, but it really just seemed to be too much of a pain in the butt to keep track of.
Right now, I stick to 1200 calories. When I've reached my goal weight, I plan to switch into a muscle gaining regiment and will consciously increase my protein. But I've lost 77lbs so far without really paying attention to percentages and worrying more about total calorie intake.
All that being said, I also know that most health professions recommend less than 40 grams of fat per day.
