Tamara is writing an article for her local sports club’s newsletter. In the article, she claims physical-fitness programs shouldn’t place so much importance on weight, but should instead focus on the health benefits of exercise and good nutrition. Here’s one paragraph from the article:

Studies show that physical-fitness programs for kids should not focus on weight loss. Instead they should focus on how regular exercise and a healthy diet make you stronger and improve your mental state. If kids worry too much about their weight, they end up going on diets that are unhealthy, and they exercise to a point that’s detrimental. One study claimed that almost half of middle school girls say they have gone on diets to lose weight.
