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.
