which factors affect a person's metabolic rate most?

1) basal metabolism, physical activity, thermic effect of food
2) percentage of water, fat, and lean tissues
3) age, sex, thyroid function, muscle mass
4) energy intake and energy output

Factors affect a person's metabolic rate MOST are basal metabolism, physical activity, thermic effect of food

Explanation:

The overall measurement of the oxygen consumed under some basal conditions are BMR. By analyzing the samples of the exhaled air the amount of oxygen consumed can be determined. It should be analysed at a regular interval of time. The heat produced or the energy that is spent can be estimated from this.

There are three main factors that must be known to identify the modification of fat tissues. the basal metabolic rate that helps to know the total energy consumed, physical activity and the thermic effect of food.
