Question

(Show the math in your calculations) lan is wanting to lose weight the healthy way. His physical data are the following: Age: 25 years. Height: 6 feet, O inches Weight: 260 pounds Activity Level: Sedentary, presently consumes about 3000 Calories/day 1. Calculate his body mass index (BMI) and indicate which zone he falls into (underweight, overweight, obese). 2. Calculate the number of Calories he should be consuming based on his ideal healthy weight. 3. If he follows this Calorie requirement based on his ideal healthy weight, calculate how many pounds will he lose in one month.

Answer 1

1. BMI = weight in kg / (height in meter)^2 = 117.93 kg / (1.83)^2 = 117.93 / 3.35 = 35.2

Since the BMI is above 30, he falls into the obese range.

2. BMR for men = (10 * weight in kg) + (6.25 * height in cm) - (5 * age in years) + 5 = (10*117.93) + (6.25*183) - (5*25) + 5 = 1179.3 + 1143.75 -125 + 5 = 2203

Calorie intake for sedentary = BMR * 1.2 = 2203*1.2 = 2643.6 calories

3. 1 pound of fat = 3500 calories

Calorie deficit created if he sticks to 2643.6 calorie diet = (3000 - 2643.6) = 356.4 calories/day

Therefore in one month, the calorie deficit = 10692 calories

Number of pounds lost = 10692/3500 pounds = 3.05 pounds
