Question

Clay is a 24 year old, 6 feet, 220 pound, sedentary male. Diet analysis revealed Clay's average caloric intake for three days was 6000 calories and he's maintaining his current body weight. He's also averaged 900 grams of carbohydrate, 166 grams of fat, and 226 grams of protein for that three-day period. Clay used to rodeo and is a fairly strict vegetarian, spanning the spectrum of vegan to lactovegetarian to lacto-ovo-vegetarian depending on his current mood. He also avoids alcohol and various forms of tobacco. His vitamin B12 intake averaged 0.24 ?g/day. Clay's recommendation for B12 is 2.4 ?g/day.

After body composition by underwater weighing, Clay decides he wants to lose 15 pounds. If he exercises two days each week and expends a net total of 500 calories each week and eats 500 fewer calories per week, how long should it take him to lose the 15 pounds?

Assume Clay decides to get his exercise by starting to walk more and joining a water aerobics class (he has bad knees from steer wrestling). His activity level improves from sedentary to low activity. What is his EER?

Answer 1

Mr.clay is an lactovegetarian,so he take a vitamin b12 from soy products and dairy products.it is rich in vitamin b12 .compare to animal products vitamin b12 is less in dairy products than non vegetarian.

Mr.clay is a 220 pounds approximately, he wants to loss 15 pounds approximately.for example: 1- 2 pounds expendable per week by taking 500 - 1000 calories.

According to this example Mr.clay take around 70 - 80 days for reducing his weight 15 pounds by expends 500 calories each week

EER means Estimated energy requirement. It is based on the individuals energy spending,calorie intake, age,sex, and physical activities.

EER calculation: for men ( 19 and older)

Mr.clay is a 24yr old 220 pounds, 6 feet ,sedentary to low activities.

Weight and height in metric units( 99.79 and 1.82 respectively ) ,

physical activity( low activity = 1.11).

Formula:

662 _ (9.53 × age) + physical activity × ( 15.91 × weihgt) +539.6 × height.

= 662 _ (9.53 × 24) + 1.11 × (15.91 × 99.79) + 539.6 × 1.82

= 662 _ 228.72 + 1.11 × (1587.66) + 982

= 433.28 + 1762.30 + 982

= 3177.58

Mr.clay's EER is 3177.58.
