What would be the best way to drop a few (5-10) over a few weeks while maintaining muscle mass? I've got a trip coming up with a LOT of climbing, and I've been training, and have built up a good muscle base, but I want to lose as much fat as possible to make the climbs as easy as possible. I don't eat white flour, potatoes, rice, dairy, beef, pork, or fried anything, but what else can I do? I'm going to continue riding up until the trip, with hill work alternating with long mileage days (hopefully a century each weekend) so I need energy to ride, but want to lose fat. I don't have a lot of weight to lose (BMI of 20) I probably have about 10 pounds that I could safely lose.
