A 61.1 kg person eats two 41.2 g brownies with nuts?

Question

What percentage (%) of their daily basal metabolic rate have they ingested ?

How long would it take, in minutes, for the person in the above question to walk off all the calories in the two brownies ? Walking requires energy equal to 2.5 times the basal metabolic rate.

Do NOT consider the energy needed to digest, absorb, and metabolize the snack itself, which the text describes as 10% of the ingested amount of food. Use the total amount of the energy in the two brownies in your calculation

Answer 1

Very amusing question !
Here is my back of the envelop estimate.

Using http://www.global-fitness.com/bmr_calc.h... I found that a 30 year old 5 ft 5 woman of 134 pounds has a BMR of 1412 calories.

Here http://www.calorie-count.com/calories/it...
I found that two 41.2 g brownies provide 330 calories, 23% of the BMR.

A minute walking requires 2.5 x 1412 /(24x60) = 2.5 calories. As 330/2.5 = 132 minutes one needs a 2 hours and 12 minute walk, to burn the energy of the two brownies.

Answer 2

[Part 1]

(4.04)(grams of brownie)=calories of brownies
(weight of person)(24)=BMR

(calories of brownie)/(BMR)

Then multiply by 100


PART 2

(2.5)(BMR)(1/24)(1/60)= #
(calories of brownie)/# = Howlong it takes

Answer 3

Hi. Well, if she has to run away from the nuts to get to eat them herself it would have to depend on the stamina of the nuts.
