Giggi, stand up to your Mom, Next time she brings the junk over tell her NO, then put it back in her car. Tell her ,everytime you bring it over it goes back to your car. My son is 17 and a JR in high school, and we both know a girl his age that is close to 300 lbs, and when she was in the 5 grade she was 190lbs then. She is also 5ft 8in tall. Both of her parents are overweight. And don't care what the kids do. Im sure if you continue to stand your ground with better eating and now that Summer weather is coming, getting out to do more exercising, like walking ,bike rides.Swimming. Your Mom will see the whole family change for the better. And who knows maybe you will her do some changing! Good luck! Turtle Gal
