Tonya is 5 ft 3 in. tall, weighs 151 pounds, and is 38 years old. Her waist
circumference is 37 in. As a receptionist for a law firm and mother of two
socially active children, her life is busy but sedentary. She simply does not
have the time or energy to stay with an exercise program after working all
day and caring for her children. She would like to lose about 20 pounds but
knows “dieting” doesn’t work for her—all the diets she has tried in the past
have left her hungry and feeling deprived. Losing weight has taken on
greater importance since her doctor told her that both her blood pressure
and glucose level are at “borderline” high levels.
•-What is her BMI? Assess her weight based on BMI.-She has a BMI of
26.7, overweight
•-Estimate her total calorie requirements using the Mifflin-St Jeor
method of calculating BEE and adding calories for a sedentary
lifestyle. How does it compare to the level of calories recommended
in Table 8.3 for a woman of her age and sedentary lifestyle?-To
estimate Tonya's total calorie needs using the Mifflin-St Jeor method, we first
calculate her Basal Energy Expenditure (BEE): BEE = (10 × weight in kg) +
(6.25 × height in cm) - (5 × age) + 5. Converting her weight and height,
Tonya weighs approximately 68.5 kg and is 160 cm tall. This gives us BEE =
(10 × 68.5) + (6.25 × 160) - (5 × 38) + 5 = 1443.5 calories. For a sedentary
lifestyle, we multiply the BEE by 1.2, resulting in approximately 1,732
calories per day. This estimate can then be compared to the recommended
calorie intake for women of her age and activity level to determine if
adjustments are necessary for weight loss.
•-Which calorie level do you think is most accurate? Why?-To achieve
weight loss, Tonya may need to consume fewer calories than her estimated
total of 1,732 calories per day. A reduction of 500 calories per day is often
recommended for a gradual and sustainable weight loss of about 1 pound
per week.
•)How many calories would she need to eat to lose 1 pound of
weight per week if her activity level stays the same? Two pounds
per week? Is a 2-pound weight loss per week a reasonable goal?-A
daily intake of around 1,200 to 1,500 calories might be more appropriate,
provided it includes nutrient-dense foods to ensure she meets her nutritional
needs.
•-To help her avoid feeling hungry while eating fewer calories, what
foods would you recommend she consume more of? She knows she
