6. Case #3: Use of Growth Charts to Monitor Weight Fluctuation During Adolescence

Don, an 18 year old male, wants to lose weight in order to make his college lightweight freshman crew team, since he does not think he is good enough to make the heavyweight team. He underwent early puberty and gained a large amount of weight between 11 and 13 years of age, which he maintained throughout high school. During those two years, his stature increased by 10 inches, from 56 to 66 inches. He has been "getting in shape for the season" by eating a balanced, low-fat diet and exercising regularly (aerobic and resistance training). He has dropped his weight from 200 to 180 lbs. However, he wants to decrease his weight to 155 lbs, at a stature of 71 inches, so that he can try out as a lightweight.
