Scientists Can Now Turn Off Hunger
October 1, 2013
At the University of North Carolina School of Medicine (NCSM), researchers have figured out how to turn off hunger.
Garret Stuber, lead author of the study said: “The study underscores that obesity and other eating disorders have a neurological basis. With further study, we could figure out how to regulate the activity of cells in a specific region of the brain and develop treatments.”
Stuber’s team focused on the gaba neurons in the bed nucleus of the stria terminalis (BNST) that is part of the amygdala which controls emotion in the brain.
BNST connects the amygdala and the lateral hypothalamus (LH) which oversees primal functions like eating, sexual behavior and aggression. Through electrical signals, the BNST and the LH communicate.
The study asserts: “The growing prevalence of overeating disorders is a key contributor to the worldwide obesity epidemic. Dysfunction of particular neural circuits may trigger deviations from adaptive feeding behaviors. The lateral hypothalamus (LH) is a crucial neural substrate for motivated behavior, including feeding, but the precise functional neurocircuitry that controls LH neuronal activity to engage feeding has not been defined.”
This study identified the LH as the modulator of “food intake” which could be manipulated to suppress feelings of hunger.
The synapses of mice were stimulated with an optogenetic technique that utilized light being shone directly on those synapses.
When the light was registered with the BNST, the mice began to eat voraciously; despite being fed recently. Shockingly, the mice craved foods high in fat.
In fact, the mice turned to overeating immediately – until the laser stopped emitting light onto the BNST.
Proof that the foods and drinks we consume cause obesity are ignored in light of this new finding that could easily become a control mechanism by which population’s desire for food can be artificially suppressed.
Earlier this year the American Medical Association (AMA) published a report classifying obesity as a disease.
Samuel Klein, director of the Center for Human Nutrition at Washington University School of Medicine said : “The American Medical Association’s recognition that obesity is a disease carries a lot of clout. The most important aspect of the AMA decision is that the AMA is a respected representative of American medicine. Their opinion can influence policy makers who are in a position to do more to support interventions and research to prevent and treat obesity.”
The AMA stated that obesity is a national problem.
The UN Food and Agriculture Organization (FAO) stated that the starving people of the world cost $3.5 trillion in healthcare and lost productivity – and this is simply unacceptable.
Between wasted food and resources, there must be a concerted effort such as a global campaign to combat this problem.
To make matters worse, the phnomenmon called “metabolic syndrome” suggests that obesity in children is linked to their brain function and cognitive capacity. Simply put: fat kids are stupid.
In a study published, MRI scans revealed that differences in the brain structure among overweight children are significant when compared to other children.
Dr. Antonio Convit, lead author, correlated his findings with other psychiatrists, as well as worked in conjunction with the National Institutes of Health (NIH) to concoct a proactive diagnosis that could label children with metabolic syndrome under five “warning signs”:
• Abdominal obesity
• Low cholesterol
• High triglycerides
• High blood pressure
• Pre-diabetic levels of insulin resistance
Convit wants to use these methods to develop a classification for overweight children in America so that the psychiatric industry can work together with the pharmaceutical corporations to develop drugs. He estimates that 54% of American teenagers are overweight or obese and that 40% struggle with weight-challenges based on metabolic syndrome.
The World Health Organization (WHO) has collected data on obesity since 2005, employing scientists to analyze the average global body weight as 137 lbs. However WHO also points out that these averages are dependent on region. WHO admonishes North America’s average body weight at 178 pounds.
WHO complains that America is the fattest nation and a drain the rest of the world’s resources.
Ian Roberts, professor and co-author of the WHO study, said: “If every country in the world had the same level of fatness that we see in the USA, in weight terms that would be like an extra billion people of world average body mass.”
WHO asserts that the lack of “surveillance systems and monitoring” of over-weight people are not “integrated into national health information systems”. They demand that obese people be surveilled by the healthcare industry and governmental agencies to reduce “behavioral and metabolic risk factors” in low-income communities.
