Explanation / Answer

Physical activity level decreases our basal metabolic rate by by 1 to 2.5 times is false .
Physical activity level is the way of expressing the person's physical activity daily in number or it can be said as estimation of person's total expenditure of energy.
When physical activity level is related to basal metabolic rate we can say that amount of food energy required for a person for the physical activity and to maintain particular life style.
The physical activity level and basal metabolic rate are correlated in a way that a person performs physical activity from day to day life.
Now a days, no person is not vigorously active mostly everyone are sedentary with little movement.
If a person is agriculture worker or a person who do swimming for 2 hours daily can have a physical activity level of 2 to 2.5.
Thus a person can have a physical activity level of 1.4 to 1.6 when he leads a sedentary lifestyle and have 1.70 to 1.9 physical activity level when he is a construction worker or person running one hour daily.
