Question

2. An adult at rest need about 2000 kCal energy per day, which is called basal metabolic rate (BMR) What power output does this BMR correspond to in watts? What is the energy of BMR been used for? After one day, where has these energy gone and in what form? Some people are promoting banana diet. Using the nutrition fact on this webpage: https://en.wikipedia.org/wiki/Banana, How many bananas would one need in one day on BMR? Do you think if the single food Banana diet (eat only bananas) is healthy? Why or why not. Optional, open-ended, no mark for this sub-question) a) b) c) d)

Explanation / Answer

Answer:

a)

Given BMR in Kcal=2000 per day ,

Or 2000/24 Kcal/hr =83.33 units

1 watt=0.86kcal/hr

Thus, required energy in watts=83.33/0.86

= 96.89 watts.

b)

This energy is used for growth and development of body, like increase in mass.

c) 1 banana=89calories

Number of banana required=2000/89

= 22.47 or about 23 bananas.

d) No

Eating single banana diet isn't healthy. Though it is very nutritional, but doesn't contain all the body requirements.

a)

Given BMR in Kcal=2000 per day ,

Or 2000/24 Kcal/hr =83.33 units

1 watt=0.86kcal/hr

Thus, required energy in watts=83.33/0.86

= 96.89 watts.
