My 14 (15 in a month) year old son is also a little over weight. As soon as we saw him gain a little weight, we tried to put a stop to it. Unfortunately, my son is not into sports. He doesn't watch and he doesn't play. So, it's really hard to loose weight if you don't do anything physical daily. But, last summer, we signed him for teen boot camp. They made the teens work out 3 times a week and gave them lesson on nutrition and eating habits. He lost a little weight, but not everything he needed to loose. This summer he begged us not to sign him up for that boring boot camp again, So, we made a deal. He has to exercise on our home equipment for 30 minutes per day and takes our dog for a walk for 20 minutes daily. I am hoping he can keep up. Unfortunately, both my husband and I work and we can't tell what he does at home. I hope he will show some responsibility this summer and work out, even when no one is watching.
Oh, yes, he also rolled his eyes at me when I mentioned Spark Teens.
Does your son play sports? If not and he liked sports, I would totally recommend signing him up for something this summer. Good luck.
It maybe too late to go back and make a new start, but it's not too late to make a new ending.
