There are those who can and who can not, but can learn. Some people can stay on a diet and lose weight, do not ever regaining the weight lost, and there are others who, though thinner, is inexorably destined to put on the pounds lost so hard. The difference in maintaining weight loss long term, the researchers explain the Miriam Hospital in Providence (Rhode Island, United States), makes the brain's response to stimuli of hunger and images of food, the study published in Journal of Clinical Nutrition that, through functional magnetic resonance imaging, we can highlight the differences in patterns of brain response and, therefore, explain why some people are able to maintain weight loss, while others are predisposed to regain it once lost. The goal, the researchers explain, is to find a way to "teach" especially in overweight and obese people to respond to the stimuli of food: the maintenance of weight loss, in fact, is one means to counter the emergence of ' Obesity, defined by WHO, "a major public health problem worldwide."
The researchers have submitted pictures of foods in three groups - people of normal weight and obese individuals who had lost at least 15 pounds and were able to maintain weight loss for at least three years - and have then analyzed the responses of the brain. By MRI revealed that before the images of food people had managed to stay in shape were more likely to activate the brain areas associated with controlling the behavior compared with normal weight and obese participants: these results, the researchers suggest that you can learn to stay lean, learning how to respond "cerebrally" differently to stimuli of food. "It's possible - says Jeanne McCaffery, lead author of the study and professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University - that these responses of the brain can lead to preventive or corrective behaviors that promote weight control in the long term" .
