Professor Tremblay, a professor of kinesiology at Laval University in Quebec, Canada, who led the study, examined the lives of 15 adults, observing their energy usage and expenditure during mental work and rest. The results showed that after working on a computer for 45 minutes, they only burned 3 calories; however, compared to resting for 45 minutes, these individuals consumed 220 more calories in food after working. He noted that while the 3-calorie expenditure is minimal, they consumed an amount of food equivalent to three apples.
"Mental labor keeps people sedentary at their desks, increasing the instability of glucose demand," said Professor Tremblay. He believes that the increasing number of people engaged in mental labor in the "Information Age" is a significant reason for the rise in obesity over the last 20 years.
