At 5' 7", 150, your daughter is about 17 pounds heavier than the recommended or ideal weight for her height, although if she has a large frame, 150 could be more realistic for her. If her frame is smaller, she could very well be correct in wanting to pare down her weight. She most likely wants to do it in the easiest way possible and may see diet pills might seem a good way to make it easier. Think of the commercials on television which tout diet pills as a means of reducing weight and it's not too suprising that she has inquired about them. Even fitness magazines have ads for such products though to my mind they don't belong there. Encouraging her to use a healthy diet which includes occasional treats but consists mostly of lean proteins, good fats and complex carbs, in addition to exercise, may start her on a lifelong love of a fit lifestyle. Americans overconsume calories and underconsuming calories has been studied and is proven to increase longevity as long as nutrient requirements are met. If you look at the Okinawas, Sardinans and Seventh Day Adventists who have the longest life expectancies, they consume far fewer calories than most and that is much more desirable than the typical diet of the over fat. I would not be too worried although it could be a good idea to inquire into why she feels it's time to reduce her weight. If someone has called her fat, indeed, she could develop disordered thinking but most likely she just wants to slim down and 150 pounds for 5' 7" is toward the heavier end of the weight range for that height with 121 pounds being the low end and 136 pounds being the ideal. My 15 year old, who is slightly shorter than your daughter and a bit heavier, has shown an interest in losing weight. It's her age and the fact that both her parents are naturally slim and the bombardment of unrealistic media images of what women should look like. She skips breakfast and does not eat well at lunch, comes home starving and overeats. I have been eoncoraging her to change her eating habits and to use her bike more often. She is exercising more but her eating habits remain poor in spite of my guidance and nutrition is a hobby of mine. We are getting a family membership at the Y since my husband wants me to help him build muscle and I plan to use it to get both my teens working out. I am rather excited to make exercise a family affair and to extend my influence over a fit lifestyle into that arena since I am in control of the family diet and try to keep it well balanced and healthy. When they are "out there", I have no control and they often make poor choices but at home, they eat well. I hope someday my influence will cause them to feed themselves and perhaps my grandchildren
in the way I feed them now.
Your daughter is an athlete and I think you could get her working out with you and eating properly to slim down without diet pills. It would enhance her performance as an athlete. Diet pills have side effects whereas balanced diets and exericse done properly do not.
It's wonderful she communicates with you and came to you for advice.
