Based on BMI, both are overweight. As per WHO, A healthy waist to hip ratio for women is under .85 and for men is .90 or less.

3. Answer is "Measuring the heat produced in a sealed chamber"

4. Body builders, Athletes and sportspeople, pregnant women, physically challenged/disability people and elderly.

5. Age, muscle mass/body size, diet, physical activity, genetics and hormonal imbalances
