Thinking Too Much Could Make You Fat

Despite the low energy cost of mental work, students who participated in the research consumed 23.6 per cent more calories after intellectual tasks  Photo: ALEXANDER BRATTELL


Pagi ni I agak free sikit after a few months busy with office works and most of my papers were already submitted to my boss for approval. Legaa... So pagi ni dok mengemas my external hard disk. I have to copy all my files from the old hard disk to a new hard disk. Hard disk lama tu dah mula meragam, some of the files dah tak boleh nak access... Masa mengemas tu terjumpa satu article, very interesting... I copied from somewhere in 2009, eh dah lama tu, 2 years ago....Sekarang ni persoalan, kenapa lately berat I semakin naik dah terjawab, hehehe.. Cari alasan tu...

So here is the answer:

Researchers found the stress of thinking caused overeating with heavy thinkers seeking out more calories.
The research team, supervised by Dr Angelo Tremblay, measured the spontaneous food intake of 14 students after each of three tasks.
The first was relaxing in a sitting position, the second reading and summarizing a text, and finally 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 discovered that each session of intellectual work requires only three calories more than the rest period.
However, 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 23.6 per cent and 29.4 per cent increase, respectively, compared with the rest period.
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.
Jean-Philippe Chaput, the study's main author, said: "These fluctuations may be caused by the stress of intellectual work, or also reflect a biological adaptation during glucose combustion."
The body could be reacting to these fluctuations by spurring food intake in order to restore its glucose balance, the only fuel used by the brain.
Mr Chaput added: "Caloric overcompensation following intellectual work, combined with the fact we are less physically active when doing intellectual tasks, could contribute to the obesity epidemic currently observed in industrialised countries.
"This is a factor that should not be ignored, considering that more and more people hold jobs of an intellectual nature."
The results of the study, carried out at Universite Laval in Quebec, Canada, are published in the journal Psychosomatic Medicine.
