A normally active 21-year-old college student is 5'8" tall and weighs 160 pounds. While working out at the fitness center, he student drops a 15 pound weight on his foot. After seeing the doctor at the student clinic, X-rays show three fractured bones in the foot. The doctor decides to put the student in a cast for four weeks and on crutches for the first two weeks. The doctor cautions the student to be careful. When the student returns in four weeks to get the cast removed, the doctor notices that the student has gained 10 pounds and attributes the weight gain to the student's decreased activity level while wearing the cast. Is it realistic that someone could gain 10 pounds in a 1-month time frame? Why or why not? Calculate the student's BMI before and after the accident - what is the difference in BMI between pre and post injury? Be sure to show calculations. Discuss concerns the doctor might have with the weight gain.
