Food addiction: A brief overview
A current and major growing threat to the worldwide public health is the obesity epidemic. One proposal for certain types of obesity, such as those associated with binge eating disorder is that the individual suffers from a food addiction. A food addiction can be described as compulsive overeating by an individual and their lack of control of their food intake. The purpose of this paper is to describe the neurobiological bases of food addiction and how this relates to the neurobehavioural aspect of overeating and obesity.
According to reports from the Centers for Disease Control, during the past thirty years the average rate of obesity in the US adult population has risen from under 20% to 35.7%. Secondly, during the same period, childhood obesity has tripled to a rate of 17%. It has been currently found that in more than a third of all children and adolescents are now considered to be overweight or obese. These shocking statistics show that a high prevalence of obesity appears to have increased significantly in the United States. It also continues to be a major public health concern, the total medical costs of obesity within the United States were estimated at $147 billion in 2008, and it is believed to continue to increase with the rising cost of health care. Secondly, obesity is also now considered to have become a global phenomenon. The World Health Organization has stated that obesity is responsible for approximately 8% of health costs in Europe and approximately over 10% of total deaths.
The onset of obesity is believed to stem from multiple causes, both physiological and environmental. An example of a cause of obesity might include the lack of exercise, however in this review I will foc...

...vation or deep brain stimulation of the rat subthalamic nucleus, a separate node within basal ganglia motivational circuitry, reduces motivation for cocaine while leaving food motivation relatively intact
Conclusion
Since that eating food is necessary for survival and that it is believed that reward circuit is assumed to be evolved in influencing this survival behavior. One must look at the underlying neural circuitry in order to undersand why individuals engage in overeating. It seems that the accusatory nature of assuming an individual is obese due to palatable and unhealthy foods isn’t always the main concern. As stated in the essay it would make more sense of asking why individuals engage in overeating behaviours to the point that neural circuitry is altered in a manner which will allow the individual to be engaged in the behavior for extended periods of time.

  • Gluttonous & Slothful Behavior: Genetically Inclined or Choice?

    1568 Words  | 4 Pages

    Scientists examined the centuries-old “sin” of gluttony and sloth with several experiments studying genes that prove we are prone to certain behaviors, low serotonin levels that increase the prevalence towards self-pity and lack of motivation towards physical activity, and a lack of leptin secretions that fail to suppress ones appetite often resulting in excessive overeating. However, there are others that strongly believe that we have a choice over gluttonous and slothful behavior and that staying clear of sugars and simple carbohydrates as a result of making healthier food choices will also increase in one’s energy levels.

  • Why Dieting Doesn't Usually Work

    614 Words  | 2 Pages

    Sandra Aamodt is a neuroscientist and science writer that received her biophysics degree (undergraduate) from Johns Hopkins and her Ph.D. in neuroscience from the University of Rochester and then went on to do research at Yale. In her TED Talk, “Why dieting doesn’t usually work”, Aamodt talks about the brain and that hunger is controlled by it, specifically the hypothalamus. She then explains that there are “set points” for weight, and they depend on each individual. She then goes on to mention that dieting is really ineffective, in part due to the fact that our bodies have not yet evolved, and so our bodies believe that we are undergoing a famine when we eat less, so then fat is stored. She explains that 80% of girls have dieted by the time that they are 10. After that, she explains that there are 4 healthy habits (eating fruits and vegetables, exercise, not smoking, and drinking in moderation) that lead to a lower risk of death. However, weight does not correlate with that. Finally, she explains how to fix this problem: mindful eating. She states that understanding the bo...

  • Neurotransmitters

    659 Words  | 2 Pages

    The study presented in this presentation focus on four different aspects of the influence of neurotransmitters that have an influence on eating. The first aspect is a 36 amino acid peptide transmitter known as the NPY. The NPY contains five different receptors; Y1, Y2, Y4, Y5, and Y6. Y2 is specifically geared towards memory. Y5 pertains to eating. Y6 is found in some animals, but not really found in humans. The Y1 and Y5 receptors are specifically for eating. The more NPY found within the body, the more a person would eat. A question, which was presented in this presentation, was if certain areas of the brain could be identified as being responsive to the metabolic action of the NPY. In order to study this idea, and experiment was performed where NPY was injected directly into different target areas. From this, it was shown that there were specific areas of the brain that responded to the levels of NPY differently.

    Americans went from being attached to the fast food culture to depending on it. The result--obesity; a negative effect of the fast food culture. Morgan Spurlock experimented with eating McDonald 's food for breakfast, lunch and dinner; In just five days, he added ten pounds. He thus found out that fast food restaurants are the single greatest contributor to the obesity epidemic in America (Gilbert). “Functional neuroimaging studies further revealed that smell, taste, and appearance of food produce a similar effect as drugs of abuse. Many of the brain changes reported for hedonic eating and obesity are also seen in various forms of addictions” (Liu et al). Fast food restaurants selectively choose certain flavors and effects, to create craving and dependence on their food. “Animal studies have shown that the predisposition to food addiction in offspring, was caused by feeding rat mothers junk food, consisting of fatty, sugary, and salty snacks, during pregnancy and lactation” (Liu et al). Apart from chemical factors such as ingredients like sugar and salt, external cues also lead to craving for food despite satiation. Advertising on television further elicits food cues encouraging even normal weight children and adults to seek out food despite the lack of hunger signals (Liu et
