Do you play sports, but still gain weight? Scientists argue that hamsters will help explain why physical activity makes a person eat more.

Scientists have long been concerned about this amazing paradox, in which so many people on a diet begin to recover vigorously after physical exertion.. Hamsters can help to get an answer to this riddle.. Experiments involving these animals showed that brain cells change shape and size in the area that controls appetite immediately after exercise.. This is what makes animals eat more food in order to make up the number of burned calories..

Well, increased appetite and leads to overeating, which culminates in weight gain. Hamsters change their behavior depending on the time of year, as scientists have found. Siberian hamsters that do not hibernate, even lose weight by half in winter, because they do not need so much food to survive. Brain scans showed that cells in the hypothalamus area change size depending on the season. The hypothalamus regulates the appetite not only in animals, but also in humans..

In winter, when the days are shorter, the cells shrink, and this affects the hormones released to the brain, which affects the appetite of rodents and leads steadily to weight gain. And the release of these hormones depends on the level of physical activity.. The problem with the implementation of the popular advice “eat less, move more” is that after these movements people feel powerful hunger, because they are biologically programmed to eat food after physical exertion www. medikforum. ru.
