Consider two friends who go to Burger King every day for lunch. One of them orders a Double Whopper sandwich, large fries, and a large Coke (total Calories = 1300) while the other orders a Whopper Junior, small fries, and a small Coke (total Calories = 800) every day. If these two friends are very much alike otherwise and have the same metabolic rate, determine the weight difference between these two friends in a year. The metabolizable energy content of body fat is 33,100 Cal/kg. The metabolizable energy contents of different foods are given in problem statement.

The weight difference of the two friends in a year= 36.93kg

Explanation:

Step 1

First calculate the difference in calories for lunch by subtracting total calories of friend 1 and 2:

Difference in calories=(total calories of lunch of friend 1) - (total calories of lunch of friend 2)

=1600-800

=800 cal/day

Step 2:

Now calculate the weight difference between both friends after 1 year by using the formula:

weight difference= yearly calorie difference ÷ energy of fat content

=(800×360/33100)

=8.82

1 food calorie= 4.1868kJ

=8.82*4.1868

=36.93kg
