- The body mass index (BMI) of a 1.6-m tall woman who normally has 3 large slices of cheese pizza and a 400 ml Coke for lunch is 30. She now decides to change her lunch to quarter kilograms of watermelons, oranges or apples plus a scope of ice creams. Assuming that the deficit in the calorie intake is made up by burning body fat, determine how long it will take for the BMI of this person to drop to 20. Use the data in the text for calories and take the metabolizable energy content of 1 kg of body fat to be 33,100 kJ. Assuming that one slice of pizza contains 350 calories and 200 ml coke contains 87 calories.A 20 day old chicken, weighing 500 grams, is growing 1.25 g feather per day, depositing 10 g of protein and 7 g fat per day and eating 70 g of feed per day. Using the information below. calculate: 1) the daily requirement for ileal digestible protein 2) the daily requirement for AME 3) the ileal digestible protein and AME content per kg diet to match the requirement calculated in 1 and 2.

- The order is for Total Parenteral Nutrition (TPN) 250 mL of Aminosyn II 5% (protein source), 1000 mL D25W (carbohydrate source), and 500 mL of Lipsyn II 10% (fat source) to be administered IV. How much nutritional value, in kcal, will the client be obtaining from the protein source infusion? Assume 1 g of protein provides 4 kcal of nutritional value. Question 1 options: a) 50 kcal b) 165 kcal c) 100 kcal d) 82.5 kcalBasal 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…For Flintstone Vitamin supplements, Based on the recommended dosage, are there any individual vitamins or minerals for which the intake is greater than 100% of the Daily Value?
