Dont Overwork Your Brain- It can Make You Dangerously Fat!
The new research led by researchers from Université Laval has found that thinking hard makes people hungrier.
The team led by Dr. Angelo Tremblay measured the food intake of 14 students after each of three tasks: relaxing in a sitting position, reading and summarizing a text, and completing a series of memory, attention, and vigilance tests on the computer.
After 45 minutes at each activity, participants were invited to eat as much as they wanted from a buffet.
The researchers had already shown that each session of intellectual work requires only three calories more than the rest period.
However, the new study showed that despite the low energy cost of mental work, the students spontaneously consumed 203 more calories after summarizing a text and 253 more calories after the computer tests. This represents a 23.6pct and 29.4pct increase, respectively, compared with the rest period.
The blood samples taken before, during, and after each session revealed that intellectual work causes much bigger fluctuations in glucose and insulin levels than rest periods.
"These fluctuations may be caused by the stress of intellectual work, or also reflect a biological adaptation during glucose combustion," hypothesized Jean-Philippe Chaput, the study's main author.
