The Biological Processes Of Obesity - 1527 Words

Obesity can develop when the cumulative energy intake exceeds energy expenditure, when this happens the excess is stored primarily as fat in adipose tissues. The biological processes that regulate the energy balance are highly regulated and this mechanism can be overwhelmed, because of a need to eat when not hungry, if attractive high calorie food is presented in attractive settings, and if individuals are regularly non-mobile for extended periods. The control pathways that include short-term signaling of hunger and engorgement to the central nervous system with the hormones that come from the gastrointestinal tract, long-term signaling of energy stores to the brain via leptin and insulin, as well as the control of metabolism. Rare genetic syndromes also play a role and these present in early childhood with severe obesity these include mutations in the pro-opiomelanocortin gene and deficiencies in the leptin this demonstrates that the pathways are biologically important in humans. Mo st obesity cases develop because of modern lifestyles in genetically susceptible individuals. The changes include excessive consumption of high-energy food in tandem with low levels of physical activity and that in many societies; less affluent people have a higher incidence (Lee et al 2013). Other causes of obesity that are considered include some drugs that can cause an increase in appetite and structural damage to areas of the nervous system that control appetite.

In 2014, approximately 41 million children under 5 years of age were affected by overweight or obesity. Today, progress in extinguishing childhood obesity has been gradual and conflicting. A greater number of children are, even from before birth, on the brink to developing obesity.

Obesity is a disease that is growing rapidly and has the ability to rip families apart due to the massive destruction it causes to one’s health. Obesity is a very deadly disease and it needs to be stopped. But are there ways to prevent it and save many lives? In this essay, I will explain obesity from a biological perspective and state the different methodsRead MoreObesity As A Body Mass Index ( Bmi )1458 Words   |  6 Pagesoverweight and obesity is caused when an energy imbalance between energy consumed and calories expanded takes place. The cause for this energy imbalance is often complex, resulting from the multifactorial interactions between genetics, overeating, slow metabolism, medications, and physiological factors. Obesity can be measured in several ways; the most widely used technique is BMI. Body Mass Index (BMI) is a measure of size based on a person’s mass and height (NHLBI, 201 5). Obesity is defined asRead MoreEssay Molecular Insights into the Hormone Insulin1680 Words   |  7 Pagesunderstand its binding with its receptor and to gain chemical insight into its activities related to the production of energy. The problem of insulin resistance is also briefly explored. It is a well known fact that obesity is a growing problem in the United States; along with obesity comes a whole score of problems, mainly caused by malfunctioning insulin molecules within the body. Without insulin, the cells in our bodies slowly break down and stop functioning, since it is a hormone that has a rangeRead More1.Berenice Is 20 Years Old And A Single Parent.

Obesity has always existed in our population, but recent studies have taken an increment to make comparative data between obesity and genetics. Moreover, studies are trying to find strategies for the prevention of weight gain to help public health and avoid the rising of obesity. As consequences, childhood obesity has developed an epidemicRead MoreMotivation and the Brain1249 Words   |  5 Pagesemotions that se rve as means of brains working. The brain oriented motivational functions and features are widely applied in theories and practice. The analysis of brain structure is discussed in the section below highlighting its chemical and biological features. The brain also performs certain functions in order to motivate and initiate a response in certain situations. The context of the situations is also relevant for the assessment of motivation. The healthy eating habits are also a functionRead MoreEssay about The Nature of Psychology1480 Words   |  6 Pagespractical application of observable behavior and mental processes of organisms. Psychology differs from other social sciences such as: Sociology, History, or Economics, because psychology specifically deals with the study of an individual.
