Question

Tina W. is a 44 year old white female who has tried a number of weight-loss programs to include very strict diets. She has never exercised in her previous weight loss attempts. She takes several cardiac medications, none of which she can remember. She is 5’9” and weighs 195 pounds. Her lowest body weight was 135 pounds, when she was 30 years old. (She was able to maintain that weight for two years.) Her blood pressure is high, at 160/90. Tina mentioned that she tried numerous diets as a teenager when she weighed 170 pounds for 3 years.

a. Using the formulae in your text book, calculate Tina’s: 1. Basal Metabolic Rate (BMR) (Hint: Be sure to read note b in the BMR column of Table 8-1). What is the meaning of your calculation? 2. Estimated Energy Requirements (EER) Assume a sedentary activity level. What is the meaning of your calculation? Show your work for both questions. b. What types of exercise would you be likely to discuss with Tina? c. What would be the goals of her treatment?

Answer 1

a .1.BASAL METABOLIC RATE(BMR)

= 10× weight (kg) +6.25 × height (cm)- 5 × age (yrs)-161

= 10× 88.45 + 6.25 ×175.26 -5 ×44 -161

= 884.5 + 1095.3 - 220 -161

= 1598.8 kcal = 1600 kcal

(Note - 161 is used for female )

It means that her body needs a minimum of 1600 kcal of energy to maintain homeostasis.She should not consume calories less than her BMR.

2.ESTIMATED ENERGY REQUIREMENT(EER)

= 447.6 - 7.95 × age (yrs)+ PAL (11.4× weight (kg)) + 619 × height(mts).

= 447.6 - 7.96 × 44 + 1 (11.4 × 88.45) + 619 × 1.753

= 447.6 - 349.8 + 1008.33 + 1085.107

= 2191.237 kcal = 2190 kcal

(Note = PAL =Physical activity level = 1 for sedentary life)

It means she requires 2190 kcal of energy to maintain energy balance and to do consistent physical activity with good health.
