Use this graph and the equations on the graph from Owen, 1988 (May Clin. Proc. 63:503) to answer these questions.

1) predict the average resting metabolic rate (kcal/day) of a nonathletic 75 kg male

2) predict the average resting metabolic rate (kcal/day) of a nonathletic 75 kg female.

3) Assume both the male and female are 25% fat, and that both only consume 100 kcal per day by eating only 3 cups of dry popcorn. Assuming only fat is burned as a fuel, that resting metabolic rate accurately predicts actual metabolic rate, and that there is no change in other body components, how long in days will it take for the male and female to lose 5 kg fat?

One kcal = 1 Calorie (as used in food descriptions).

Each gram of fat yields about 9 kcal.

3a) days for male to lose 5 kg fat:

3b) days for female to lose 5 kg fat:

4a and 4b. Looking at the graph, approximately what is the highest and lowest metabolic rate of any 75 kg person?

5a) How long will it take for the 75 kg person with the highest resting metabolic rate to lose 5 kg of fat if they consume 1000 kcal per day?

5b) How long will it take for the 75 kg person with the lowest resting metabolic rate to lose 5 kg of fat if they consume 1000 kcal per day?
