A 45 year old Jenny wanted to determine if she is taking enough food to gain weight. She currently weighs 55kg and takes in 2,000kcal per day. The following are her activities: (1) sleep for 7 hours (2) running for 2 hours with an estimated energy expenditure of 4.5kcal/min (3) working for 10 hours with an average energy expenditure of 3.5kcal/min, and (4) rest for the remaining time with an estimated time of 1.5kcal/min.
discover what weight is needed to achieve a desired BMI. consider a person who is 5 feet 4 inches (1.63meters) tall. suppose this person wants to have a BMI of 21. what should this person weigh?
BMI (body mass index) is obtained by dividing your weight (in kilograms) by your height (in metres) squared.
To determine your weight in kilograms, take your weight in pounds, and divide by 2.2.(There are approximately 2.2lbs in one kilogram)
Weight (kg):________________
To determine your height in meters, you first need to know your height in inches. There are 12 inches in a foot, so a 6 foot person, would be 72 inches tall. Someone who is 5’6” would be 66 inches tall. (5 x 12 then add 6).Once you have the height in inches, divide this value by 40 to convert to meters.(You can use google for this calculation)
Height (m):_________________
Body mass index Formula = Body weight (kg) / Height2(m)Calculate your (or someone else’s) BMI using the weight and height values above:
