Question

In 1990, your classmate BMOC (Big Man On Campus) was 22 years old, 72” (1.83 m) tall and weighed 193 lbs (87.7 kg) with 12% body fat as measured by DEXA. He was cocky, confident, and ready for the world. Biopsy from various subcutaneous depots revealed an average adipocye triacylglycerol (fat) mass of 0.5 mg. What is the estimated number of adipocytes? A. 15B B. 20B C. 25B D. 35B E. 40B

In 2016, BMOC is less cocky and his days of being an Adonis are distant memories. Now 48 years old, he is completely sedentary, weighs 226 lb (102.7 kg) and has 35% body fat. His average adipocyte now contains 0.90 μg of triacylglycerol. What is the estimated number of adipocytes? A. 15B B. 20B C. 25B D. 35B E. 40B

He seeks your advice on improving his health and fitness. A baseline assessment reveals his daily energy intake is 2800 kcal (35% fat; 50% CHO, 15% protein) with a daily estimated energy expenditure of 2700 kcal (REE+TEF). You plan a program which includes 2550 kcal diet (25% fat; 60% CHO; 15% protein) and adds 350 exercise kcal·day-1 (total daily energy expenditure=3050 kcal). He will check back with you in 4 weeks. In theory, how much total weight and fat weight has he lost in 4 weeks? A. ~4 lbs total / ~4 lbs fat B. ~4 lbs total / ~2.5 lbs fat C. ~8 lbs total / ~4 lbs fat B. ~8 lbs total / ~2.5 lbs fat

Based on your answer above, what is the estimated number of adipocytes after 4 weeks of modified diet and exercise? A. 15B B. 20B C. 25B D. 35B E. 40B

What is the estimated fat content per adipocyte after 4 weeks of modified diet and exercise? A. 1.00 mg B. 0.90 mg C. 0.87 mg D. 0.75 mg E. 0.67 mg
