It was something that was suspected, but until now it was just that, a suspicion. However, a group of researchers from Medical Center of the University of Maastricht, The Netherlands, says to have verified that a cold moderate can help Our organism to boost energy expenditure and to lose weight.
Recommends, as a way to enhance a diet , to lower the heating (in the countries that it is needed, of course, like Holland), and for climates like for example ours, to spend more time outdoors in temperatures of around 15 degrees during 10 days.
The strategy obliges organism to generate more brown or brown fat, beneficial, that burn energy to maintain the proper body temperature.
Led by the professor and specialist in human biology Wouter van Marken Lichtenbelt, researchers studied the effects of cold in the organism for more than 10 years.
The work focused, at the beginning, on checking whether the warm environments and comfortable home or office could be responsible for the current obesity epidemic, since the majority of the population remains exposed to an ambient temperature, controlled, 90% of their time.
The research team asked those present: "What would happen if we let our bodies act to control the interior temperature?"
And the answer has just been published by the team in the specialized journal of Endocrinology Trends in Endocrinology & Metabolism. The hypothesis was confirmed that the cold benefits the operation of the organism as far as body self-regulation is concerned, and therefore, in an increase of energy and fat consumption harmful to health.
The investigation found an increase in the percentage of brown fat in the volunteers participating in the test, after remaining six hours a day at a temperature of 15 degrees, for 10 days. In addition, they pointed out that staying at that temperature was not really that hard, and all of them ended up getting used to the cold and feeling more comfortable at lower temperatures. temperature.
The researchers then concluded that the organism, to counteract the cold and not shiver, can cause an energy expenditure of up to 30% of the body's energy budget.
So, in addition to eating properly and practice exercise, They recommend getting used to spending more time at a moderately low temperature. "This way we would be more protected from obesity and we would be less vulnerable to sudden changes in the ambient temperature," explains Marken Lichtenbelt.
