Both diet and exercise wise, what would be the fastest way to lose fat/poundage? I see many people saying that you should change your meals into smaller, more frequent portions. How many a day, what should the quantity be, etc. A good goal for me would be about 20 pounds off, but I don't know how long that would take with a strong diet. I play 2 hours of tennis everyday, as well. Maybe one hour of match play. Any help is much appreciated.
