Ironic, isn’t it? That the one time in history when diets are at their peak is also the time when the world is reporting an increase in the number of obese and overweight people. Some people have had the misfortune to try dozens of diets, like Nutrisystem, but without any noteworthy level of success. Navigate here to read more about Nutrisystem.
But once again, science has found why this may be the case–your brain could be getting in the way. How, you ask? Apparently, however earnest your efforts to lose weight might be, your body will still have to listen to your brain on whether to let go of those pounds or keep them around. In simple words, the brain has the ability to regulate how much weight your body should have with the way it makes you respond to certain stimuli.
So, you might have been wrong to blame the new diet for your inability to lose weight. In fact, this study was done on 36 chronic female dieters with an average body mass index (BMI) of 23.9. The CDC considers BMI a reliable indicator of body fat levels.
The study involved the use of fMRI (functional magnetic resonance imaging) and diffusion tensor imaging (DTI). In simple terms, these medical investigation methods have the ability to determine how the brain reacts to various forms of stimuli. Otherwise, the study involved asking the subjects to pick between food images and other control images.
The differences in the way the brains reacted to the two sort of images was dramatic – the brain was very responsive to images of food. The use of DTI also helped to establish the connection between the executive control area of the brain and the reward area of the brain.
The two areas of the brain are connected by white matter, and in individuals with better control over unhealthy eating behavior, there was better structural integrity in this connection. And this is why brain integrity might have something to do with body fat variations among people.
So, if you have continually failed to follow through on your diet, it might be because the structural integrity of this connection in your brain has been compromised. This would in turn make it much harder for you to overcome the temptation to eat unhealthy foods that ultimately lead to weight gain.
But the study does leave a few questions unanswered. For instance, is it the same for men? And what about women who have never tried to diet? Still, it should help all the serial dieters out there who never seem to get the results they expect from various diet programs understand what the cause of their weight loss failures might be, especially when they can’t fight the temptation to violate the laid out diet rules.
