Karky,
30% is a general guideline. It's not going to hurt you to go to 25% but 30 isn't bad either. You'll still have plenty of room for essential fatty acids and the other nutrients provided by fat, provided you make good choices. Monounsaturated are best (canola and olive oils). Choose few saturated fats (up 7% of your calories) and try to avoid trans fats, as Johnny boy would say...like the plague.
