1. what is the average weight for a 13 year old? about 4 feet 8 inches? thanx!!

2. im currently on a diet, so i need some healthy, low-calorie/fat foods. my sister told me that when ever i get hungry, drink water, because thats what she does. that does not work for me. i have salad, but that doesnt seem to fill me up. any other foods or advice or tips for my diet???

thanks so much!!
