I'm 14 years old, 5'4", and I weight about 105 lbs. I wouldn't say that I'm fat or overweight, but I do have a lot of excess fat around the lower part of my body, such as a thin layer of fat over my stomach and obliques, untoned legs, etc.

I'm quite self-conscious about my body, and I've been trying to make changes, but I don't have much patience to notice any visible difference as of late.

I've been cutting out a few junk foods from my diet, as well as drinking more water. I run 2-3 miles a day on the treadmill, do 100 crunches daily, and occasionally lift weights if time permits. Is there anything else that I should change/add for an ideal weight loss program?
