Question
Eating 3 (10g/per cookie) chocolate chip cookies (488 kcal per 100g) each day for one year how many pounds of weight you will put on? Take 1 pound of fat = 3500 kcal If you maintain your kcal intake (TDCE) and wish to lose 30 lb in six months by running 5 day a week. Calculate how many Calories you need to burn per day. You lose about 90 kcal/mile when running at the rate of 7.5 mph. Calculate the number of mile you need run per day and how long it will take you to complete your exercise. Show your lull step by step working.Explanation / Answer
A)
Weight of 1 cookie= 10g
Weight of daily intake of 3 cookies= 30g
Kilo calories in 100g= 488 kilo calories
Kilo calories in 1g= (488/100) kilo calories
Kilo calories in daily intake of 3 cookies = 30 x (488/ 100)
Kilo calorie intake in a year= 365 x 30 x (488/ 100) =53436 kilo calories
Equivalent of 3500 kilo calorie = 1 pound
Equivalent (of the intake) of 53436 kilo calorie =53436 / 3500= 15.267 pounds in the entire year
B)
Maintaining the above intake for six months, intake= 15.267/ 2= 7.634 pounds
Weight loss target for six months = 30 pounds
Total weight loss requirement = intake + target= 7.634 + 30= 37.634 pounds
Total Energy to be spend in kilo calories= 37.634 x 3500= 131719
Number of days per week (in 7 days) to run= 5
Number of days to run in six months= 6 x 30 x (5/7) = 128.571 =129 (approx)
(// May vary depending on which all the months are)
Energy to be spend on each running day = 131719/129= 1021.077 kilo calories
Kilo calories spend in running a mile (at 7.5miles/hr) = 90 kilo calories
Miles to run each day= 1021.077 /90= 11.345 miles
Speed of running= 7.5 miles/hr
Time spend running each day= 11.345/7.5= 1.512 hrs = 1 ½ hours (approx)
