Actually, talking about nutrition and hiring more gym teachers would be a far more constructive start to addressing the problem. Including more time for movement and physical activity during the school day would also be huge. Getting school meals under control for calories, fat, and carbohydrates would be a huge help, too. Schools are about teaching kids, right? Supporting lessons in good nutrition with providing good nutrition would be a huge step to helping out parents who are trying to teach those lessons at home. My kid gets so much homework, I found we had no time at home to get him outside to play, and he only gets gym 3 times a week (an no recess!) I was feeding him next to nothing (and packing in lunches- did you know school lunches can be 1000 calories?) and he was still gaining weight because he was given no time to move around! If I got such a letter from our school, you bet I would be at the school board at the next meeting, demanding what CONSTRUCTIVE action was being taken, rather than embarrassing kids and families? I would come ready with plenty of suggestions, because there are plenty of ways to fix the problem, but one must be consistent between home and school for any of them to work.
