Exercise and Appetite Regulation versus Adipokines Essay Example for Free

Exercise and Appetite Regulation versus Adipokines Essay Adipose tissue has long been considered a storage organ for triacylglycerol, but it is now known, that adipose tissue also produces and releases a variety of signaling molecules – †adipokines† or â€Å"adipocytokines†. Some of these adipokines are well described as regarding plasma concentration and in vitro gene transcription, secretion and effect on various cell types, but only little is known about in vivo regulation of adipokine secretion [XLAB 2008]. Adipokines may mediate insulin resistance or modulate the likelihood that obesity results in the development of type 2 diabetes [CARE 2003]. Obesity is strongly associated with insulin resistance and dyslipidemia and increased risk of cardiovascular disease (Depres J-P 1990). There are recent studies that adipokines such as leptin and adiponectin suppresses the development of atherosclerosis which is a cardiovascular disease (Reilly MP 2004). Adipokine or fat can raise such insulin levels, which promote the growth of cancer cells [FHCR 2007]. And because of these risks in chronic diseases, exercise is very important to burn fat that causes these diseases. In order to reduce risk in chronic disease and strengthening the immune system, exercise is very important. Lack of exercise may contribute of having a chronic disease which may be long lasting or recurrent. A recent study showed that intensive workouts can not only slow the progress of coronary disease, but actually restore lost coronary function when the disease is still stable. For chronically ill individuals, the psychological as well as physical benefits of exercise can be profound. Even ten minutes of light exercise a day, can help most chronically ill patients feel more vibrant, energetic and alert [PREV c. 008]. Physical activity fights the intra-abdominal fat or Adipokine tissue that can fuel risk of cancer, heart disease, diabetes [FHCR 2007]. Some people use anti-inflammatory drugs to regulate their metabolism and immune function such as Glucocortisoids. Regulation in the metabolism helps maintain the level of fat your body need. Whereas mineralocorticoids, it helps maintain blood volume and control renal excretion of electrolytes which are good for people with high blood pressures. While some anti-inflammatory drugs are just used to increase muscle and bone synthesis. Some anti-inflammatory drugs are used to stimulate secretion of hormones that burns fat. In addition to anti-inflammatory medical drugs, there are many herbs that have anti-inflammatory qualities. Some of these herbs are ginger, hyssop, Turmeric, Amica Montana and willow bark. Appetite regulation balances the food intake that results to stabling the fat that only the body needs. In appetite regulation, anti-inflammatory foods are sometimes being taken. These anti-inflammatory foods burns fat and sometimes stimulate hormones that make your brain think that you are not hungry even though you are not eating anything yet. Anti-inflammatory foods include most colorful fruits and vegetables, oily fish and certain nuts, seeds, herbs and spices such as ginger. Those following an anti-inflammatory diet will avoid refined oils and sugars, and show a preference for anti-inflammatory foods in their meal choices[Hyman M. 2006]. To regulate overall food intake, long-acting adiposity signals ultimately affect the number and size of individual meals. They, therefore, influence decisions regarding when to start and stop eating. The sense of fullness that contributes to meal termination results from mechanical, neural, and humoral signals that arise from the gut and are relayed to the brain primarily via the brainstem [AMER 2003]. Hormones that govern energy homeostasis—leptin and insulin—increase responsiveness to short-acting satiety signals (Schwartz MW 2000). Consequently, when fat stores diminish and leptin and insulin levels decrease, sensitivity to meal-related satiety signals is blunted, promoting increased meal size. Body adiposity indirectly modulates the efficacy of meal-related satiety signals from the gut, thereby influencing meal size [AMER 2003] Chronic disease may be prevented through these anti-inflammatory drugs or foods but not only anti-inflammatory drugs or foods but also accompanying these drugs with exercise and avoiding tobacco, because Exercise makes your heart stronger and improves the circulation of blood in your body. It also improves your body posture. I believe that in order to reduce the risk of developing certain common chronic diseases, regular physical exercise is an important step in taking care of your health and protecting yourself from health problems.
