Highly active people burn significantly more calories than those who are less active. The additional calorie burn occurs not just while they're engaged in their various activities, but also when they're not exercising, because people who lead active lifestyles develop higher metabolisms.
Further Factors
In addition to activity level, age, gender, weight and height affect the number of calories burned. Heavier, younger, taller males burn more than other people.
Sedentary Males
A 35-year-old sedentary male of average height weighing 145 lbs. burns about 1,883 calories each day, while a 200-lb. sedentary man burns about 2,180 calories a day.
Active Males
That same 35-year-old man who weighs 145 lbs. burns 2,430 calories per day by exercising moderately three to five days per week and burns 2,700 calories each day by exercising heavily six or seven days per week. Exercising daily increases his calorie expenditure 43 percent compared with his sedentary calorie expenditure. A 200-lb. man has a similar increase in calories burned, moving from 2,180 calories per day to 3,140 calories per day by exercising daily.
Sedentary and Active Females
An inactive 35-year-old female weighing 145 lbs. burns 1,980 calories per day. If she exercised daily, she would burn 2,850 calories per day, a 44 percent increase.
