Ghrelin Emotions

Scientifically, it has been proven that one should not make long-term decisions while hungry. Students at the University of Gothenburg in Sweden studied whether or not it is smart to make a decision when you are ravenous. A hormone that is made in the gastrointestinal tract, called ghrelin enhanced this study. Ghrelin is released when your body is searching for food as energy. When you are no longer hungry, the manufacturing of ghrelin halts. Ghrelin is also associated with drug and alcohol intake. Tests were developed to demonstrate how this happens through living organisms, the researchers at the University of Gothenburg examined rats. Although rats are not humans, they can display human-like behaviors. When an extra amount of ghrelin was inserted into the rat, they went against their regular impulses. They would gain a

Even despite electric shocks, they continued to eat until they became obese. When the researchers switched the obese rats’ diet to a healthy one, the rats refused to eat for almost two weeks. The rats that ate the fast food stopped responding to Leptin, a hormone that regulates hunger. As the rats became more obese, the amount of Leptin in their bodies indicated that the rats were on the brink of starvation; however, the rats continued to eat and become even more obese (Greviskes, 2013).

A very much known phrase is you should never go food shopping while you are hungry. We all have

10. If you are avoiding a specific food because of a bad memory, it is called food aversion. Which brain region is associated with food aversion?

This increases level provides the sense of satisfaction which obese people lack. An increase in serotonin ( a hormone in the brain) eventually leads to weight loss. The combination of a decrease in caloric intake along with the excess production of serotonin by redux is what causes some to lose body weight. This redux treatment is associated with a loss of appetite and may slow gastric emptying.

There are some myths about hunger and satiety I’d like to address. First the lack of energy (fuel) is not what causes hunger. Second if you manage to lose weight without changing your lifestyle when you go back to eating as you always did you will gain it right back. Exercising alone is not an effective way to lose weight; if you don’t change the intake of calories there is no amount of exercise that can keep up. Exercising has healthy benefits but each of us has to have balance of the correct amount of calories and exercise to be healthy.

We like everything in an instant. Individuals like fast cars, fast communication, and most of all we love fast food. Having things in life come in an instant seems great but there is a price to pay. Therefore, fast food may be convenient but it is costly. Although, fast food may save you time now, it will cost you years of your life later. Most foods that are quick and convenient are full of refined sugars, carbohydrates and other processed food. Sadly, these attributes of convenient food causes many of us to overeat. Dr. Lustig referred to individuals who eat a lot as “gourmands.” Sadly, there are a number of things that happen when we consume sugars, carbohydrate and fats. First, due to overeating an individual may have higher levels of leptin. Leptin is a protein produced by fatty tissue and believed to regulate fat storage in the body. According to Stephan Guyenet, when we become leptin resistance when our brain does not know when we are full therefore we overeat. Leptin resistance comes from a high consumption of sugar. Dr. Lustig suggest that sugar in the presence of insulin creates fat. I believe that obesity is direct effect of another underlying issue. Correspondingly, we all know the effects sugar has on our bodies, but yet we continue to consume it in high quantities. In my opinion, sugar is a drug and many people have an addiction to it. Sugars sends the same signals and high levels of dopamine to brain just as drugs. For example, I have an uncle who weighs about 900 pounds. He was not always this big, so what happened? As a child, he ate a lot of sugary foods and food that contains a lot of fat. Not only did my uncle eat unhealthy, but he was not very active. Therefore, there was a combination of factors that contributed to his massive weight gain. Obviously, his body started to become leptin resistant at some point. If you become leptin resistance and have an addiction to sugar then you

Konnikova starts her deliberations by pointing out that, “Being genuinely hungry … in the sense of physiologically needing food—matters little.” We can feel full after a meal, but receptors from the outside, like smelling, seeing, reading or even thinking about food can make us feel hungry again. We can all associate with that feeling when we want to eat something, and it’s not because we’re hungry, but because we want to. It has nothing to do with a need of our body. The author clarifies that, “Recent studies show that our physical level of hunger, in fact, does not correlate strongly with how much hunger we say that we feel or how much food

This action from human metabolism makes it harder for people to control their weight. “Losing weight has proven to be extremely difficult for large numbers of people,” even with major weight loss programs, such as weight watchers, a program used internationally, “people shed pounds but regain them and many situations gain even more,” this is called “yo-yo dieting” or the constant loss of weight only to gain it back at a later time (CDCP 54). According to Sally E. Smith in her article, “The great diet deception,” weight loss diets and products, very rarely produce long lasting results. Less than five percent of people that go on strict diets accomplish losing weight and actually keeping that weight loss off for over a five year span (Smith). Ninety percent fail, and regain a lot of it back, even all of it in many cases (Smith). A third of that five percent regain more than they had ever lost (Spake).Since dieting is so hard, healthy professionals encourage exercise or a good amount of moderate physical activity, as a way of losing or maintain weight (CDCP 54).The determination of one’s diet is based on a balance of “energy in,” “energy out” difference (Mypyramid.gov). In other words, the amount of calories that are taken in minus the calories burned. For instance, if someone wants to lose weight, the calories that are burned through the whole day need to be greater than the calories that are absorbed that day.

Obesity: one of the nation’s most critical health problems. “Overweight is defined as having excess body weight for a particular height from fat, muscle, bone, water, or a combination of these factors. Obesity is defined as having excess body fat” (“Centers for Disease Control and Prevention”). When energy input and output get out of balance, obesity arises. Many factors can cause someone to become obese such as genetics, metabolism, level of physical activity, and more. “Overweight and obesity are the result of “caloric imbalance”—too few calories expended for the amount of calories consumed—and are affected by various genetic, behavioral, and environmental factors” (“CDC Features - Obesity & Genetics”). “When a person eats and drinks more calories than he or she burns, the energy balance tips toward weight gain, overweight, and obesity” (“Understanding Adult Overweight and Obesity”). Obesity is increasing throughout the United States due to lack of healthy behaviors, big health risk, genetics and increasing in children and adults.

Elmquist & Flier (2004) investigated some recently discovered literature about the hormone leptin. This article attempted to synthesize some new documented research about how leptin contributes to the activity within the central nervous system. The purpose of this article is to identify the importance of this newly synthesized information and lead it to new discoveries by promoting several well founded research questions.

Now, in 2015, the number of searches and available information increased from ~334,000 hits to ~32, 200, 00 hits. The idea that food has similar addictive characteristics as drugs that affect the brain is quite controversial. People tend to eat when they are depressed, happy, emotional, celebrating and many other situations because food is easily accessed and not illegal. Research regarding sugar having addictive qualities was conducted in 2010 by the University of Texas and the Oregon Research Institute. Equipped with Haagen-Dazs ice cream and a group of overweight women, the researchers measured the brains reward center activity when shown images of ice cream and when tasting an ice cream milk shake; six months down the road, the group reconvened and the women once again tasted the ice cream. The results were that the woman who had gained weight over the time gap had decreased activity in the striatum, an area of the brain that registers reward, thus needing more to reach a feel good level of satisfaction (Langreth & Stanford, 2011). "The significance of this finding is that these are the same regions of the brain that light up in drug addicts who are show images of drug paraphernalia or drugs" (Wormer & Davis, 2013).

Internally, the hunger we feel is conceived from the brain. It has once occurred to me that I did not realize lunch time passing because I was too busy working. This is clear proof that internal influence of hunger is by the brain and not the stomach (Hockenbury and Sandra 63). The brain part that regulates the hunger feeling is called hypothalamus. This segment of the brain is separated into the lateral and

Plasma leptin concentration has been increased due to high tail fat diet. Leptin is secreted by adipocytes that is implicated in nutrition and cognition (Morrison 2009). Hyperleptinemia is induced by obesity and aging which is associated with dysregulation in leptin signaling; moreover, leptin signaling is affected by diet manipulation. Low affinity leptin to its receptor (Ob-Rb) and inability of upregulation Ob-Rb proportional to leptin concentration was developed by high fat diet (Mitchell et al. 2009). Also high fat diet decreased leptin receptors in cerebellum (Koros et al. 2009). Insulin and leptin are signally interrelated as insulin resistance frequently associated with leptin resistance in high fat diet ingestion and obesity. There is a positive relationship between insulin and leptin concentration and oxidative stress (MDA concentration) in plasma of overweight and obese persons (Shaimaa Essa et al. 2016). Brain oxidative stress progress insulin and leptin resistance in endogenously generated oxidative stress model (Yagishita et al. 2017). NO is a downstream signal of leptin and leptin inhibiting nitric oxide synthase activity (Calapai et al. 1999; Mehebik-Mojaat et al. 2009).

Exercise, or physical activity helps your body in many ways. For example, exercise helps control the weight of a human. It helps prevent people gaining unwanted weight and helps people who have unwanted weight to lose it. (mayoclinic.com) When we eat, we are taking in calories, and then when we exercise we burn off
