To discuss: The amount of calories needed by the individual.
Introduction: Energy is needed by the body to perform daily activities, maintain basal
To discuss: The three methods to estimate daily energy requirement of an individual.
Introduction: Energy requirement of an individual refers to the minimum amount of energy that is required by the body to function. Since the activity profile of an individual is perpetually dynamic, there are fluctuations in energy requirements throughout the day. This is precisely the reason why the daily energy requirement cannot be exactly resolved, instead, an estimate is being made based on the individual’s activity, basal metabolic rates, and the thermic effect of food
To discuss: The factors that would increase or decrease the number of calories needed in a day by an individual.
Introduction: The energy requirement can be measured by the number of calories needed by the individual. There may be situations when the body requires more calories and when it would require less. This directly affects the number of calories required in a day by an individual.

- One food calorie = 1 X 103 calories = 1 kcal. A typical adult ingests about 2200 food calories per day. (A) show that an adult uses energy at about the same rate as a 100-W light bulb. {B) Calculate the total annual metabolic energy expenditure of the 6 X 109 people on the earth and compare it with the 4 X 1020 J per year energy used by the world economy. Assume all persons consume 2200 food calories per day, which is obviously incorrect.arrow_forwardBasal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.arrow_forwardIf a non-vegetarian endurance athlete weighing 145-pounds consumes the entire can of Turkey Chili, what % of their daily protein needs would they have consumed?

- Basal Metabolic Rate Worksheet Most people can have a successful healthy diet just by estimating their quantity of food and timing their meals equally throughout the day. Your Basal metabolic Rate (BMR) is the rate at which your body uses energy while at rest to keep vital functions going, such as breathing and keeping warm. It is a good formula to work into your diet regimen to understand how much fuel you need to survive. Here is the formula: Women: BMR = 655 + ( 4.35 x weight in lbs. ) +( 4.7 x height in inches ) - ( 4.7 x age in years ) 655 + - BMR Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - (6.8 x age in year) 66 + = BMR_ This formula uses the variables of height, weight, age and gender to calculate the BMR. This is a good formula because it is more accurate than calculating calorie needs based on body weight alone. The only factor that is omitted is lean body mass (the ratio of muscle to fat that a body has). So the leaner a body is the more…arrow_forwardAre the following statements true or false? A. Most of the energy stored in the human body is in the form of fat, followed by protein. The body has only limited capacity for storage of carbohydrate. B. It is estimated that one kg of fat gain requires 2500 kcal of energy surplus. A is true, B is true O A is false, B is true A is true, B is false O A is false, B is falsearrow_forwardCalculate the daily calories needed for a 150-pound person if s/he sleeps 8 hours, sits 10 hours, stands 3 hours, walks 2 hours, and swims 1 hour in each 24-hour period.arrow_forward
- Mark is a college student who has been lifting weights at the student recreation center. Mark’s weight has been stable at 154 lb (70 kg).An analysis of the total energy and protein content of Mark’s current diet is 3470 kcal, 125 g of protein (14% of total energy intake suppliedby protein). This diet is representative of the food choices and amounts of food that Mark chooses on a regular basis. The trainer at thecenter recommended a protein drink to help Mark build muscle mass. Answer the following questions and determine whether a protein drinkis needed to supplement Mark’s diet.1. Determine Mark’s protein needs based on the RDA (0.8 g/kg). a. Mark’s estimated protein RDA in g: b. What are the maximum recommendations for protein intake for athletes in g/kg? c. Calculate the maximum protein recommendation for Mark in g. 2. Compare Mark’s protein intake with the recommended intake amounts. a. What is the difference in g between Mark’s estimated protein needs as an…arrow_forwardAssume that you want to lose 20 lb of body fat in 60 days. Your present dietary intake is 3000 Cal/ day.
