How many calories are burned while watching television for one hour?

The amount of calories burned while watching television for one hour depends on several factors including weight according to Harvard University. While a person who weighs 125 pounds can burn 23 calories an hour, someone who weighs 185 pounds burns 33 calories an hour on average while watching television.

A person's Basal Metabolic Rate (BMR) also influences the calories burned while watching television. This is the number of calories burned per hour while stationary. The more muscle mass a person has, the higher their BMR will be. A person's BMR also increases for 1/2 hour after engaging in physical activity, such as cardiovascular exercise.
