The Key to Weight Loss

The Key to Weight Loss

New research suggests that higher-level brain functions have an important role in weight loss. In a study among 24 participants in a weight loss clinic, those who achieved the greatest success in terms of shedding pounds showed more activity in the regions of the brain of the lateral prefrontal cortex associated with self-control. If you want to lose weight to be pretty I have to tell you that this is not the solution, being beautiful is a complement to many things, but you can improve in parts, you can start with the easiest and what will be a more noticeable change, go with an expert dentist for dental restoration Tijuana, after that you can start your healthier life and wait for the gradual changes.

What they find is that, in humans, the control of body weight depends to a large extent on the areas of the brain involved in self-control and self-regulation. That area of ? the brain has the ability to take into account long-term information, such as the desire to be healthy, to control immediate desires.

It is known that 2 hormones, leptin and ghrelin, cause the body to eat in an environment of weight loss. Previous research confirms that these hormone levels change rapidly when you lose weight. All those who lose weight see this change in leptin and ghrelin. It’s just that some people, for reasons we do not know, are able to maintain their self-regulation against that signal.

To assess the roles that these hormones and self-control have in achieving weight loss, the scientists evaluated 24 subjects in a weight-loss clinic. Before starting with a standard diet to lose weight of 1 thousand 200 kcal / day, all participants received a study of functional magnetic resonance imaging (fMRI) of the brain, which evaluated the regions, including the lateral prefrontal cortex, which is linked to self-regulation, and the ventral medial prefrontal cortex, an area of ??the brain involved in motivation, desire and value.

Usefulness of cognitive behavioral therapy
The subjects were shown images of appetizing foods, as well as images of landscapes that served as control. The researchers compared the response of brain activity to food images, particularly images of high-calorie foods, for each subject at baseline, month and 3 months. When we show pictures of appetizing foods, the area of ??the ventral medial prefrontal cortex becomes more active in fMRI.

During the study, the researchers noticed that, at month and 3 months, the signal of the ventral prefrontal cortex decreased and fell more in the people who were more successful in losing weight. In addition, the signal of the lateral prefrontal cortex involved in self-control increased throughout the study.

In the fMRI, the area of ??self-control increased its activity and the value area decreased its activity. And the amount of change predicted a successful weight loss. Although all the participants lost weight, those who achieved the greatest weight loss had levels of fMRI that indicated a better capacity for self-control. And, at the end of the three-month study, the hormones ghrelin and leptin began to return to the baseline, suggesting that a new set point was achieved.

These results suggest that weight-loss treatments that increase self-control, such as cognitive-behavioral therapy, can be helpful, particularly when stress is involved in overeating. Stress interrupts the control mechanism of the lateral prefrontal cortex, but it may be able to train people to look for a different strategy.
