Adipose Tissue: Overview of Physiological Functions
Hong Lan Huang, 1296959
Abstract With increasing number of obese people in the world, people tend to have more interests in body fat other than its basic structure. Many people often struggle to lose weight in order to have perfect body shape, or to prevent obesity induced chronic diseases. Failure to prevent excess of body weight in one’s body might result to life threat diseases such as obesity, type 2 diabetes, and heart diseases. Before, body fat is simply known as a lipid droplet cell. Today, more studies and experiments are conducted in favor of examine the importance of adipose tissue’s function in the human body. Adipose tissue (body fat) has a significant physiological role to maintain body’s homeostasis. The following review will provide prominent knowledge of the adipose tissue’s development, structure, functions, and its relation to obesity. Adipose tissue is extremely essential for one’s health by performing as a heat generating organ, an immunological organ, and an endocrine organ.
Introduction It is interesting to know that many people might perceive higher proportion of body fat in human is both advantageous and disadvantageous. On the one hand, fat protects human’s bodies. For example, some people believe that fat people feel less cold than thin people in extreme cold weather. In other cases, some people believe that fat people get less injured than thin people in an accident. On the other hand,
In this research paper we will be looking at the topic of obesity and the social ramifications that it holds. We will first look at obesity in a broad way. Then we will focus on obesity and its effects on children. And finally, obesity and adulthood will be covered. The topic of obesity is important to the field of sociology because obese people make up a significant portion of the world’s population. In addition, the manner in which obese people are treated has a significant effect on society as a whole.
Towards the end of his medical training in the early 1980s, Gokhan Hotamisligil was working on a unique tumor case on a patient and found they were comprised primarily of fat cells. The fatty tumors were due to a rare condition, Proteus Syndrome. Working in the field of metabolic regulation Hotamisligil began to explore the underlying pathways for insulin resistance. In his dissertation he discovered that the fat tissue of obese animals and humans were capable of producing inflammatory mediators. His research helped shape the current view of fat tissue as a “discrete, active organ in its own right, continuously exchanging messages with the rest of the body by way of the bloodstream.” By early 2002 Hotamisligil and his laboratory made
It is estimated that males have approximately 3% essential body fat while females have about 12% (Kenny et al., 2015). On the other hand, non-essential fats are the body’s storage of excess fats in the diets. The non-essential fats are stored in the muscles, abdomen and beneath the skin (Kenny et al., 2015). Males are estimated to store approximately 12% non-essential body fat compared to females who store approximately 15% (Kenny et al., 2015). A higher percentage of non-essential body fat indicates that an individual is at higher risk for cardiovascular disease, obesity, and
Words were used to describe positive associations or negative associations. The test was based on how people view fat or thin people subconsciously or consciously. Compared to the more personal test regarding racial profiling, this test’s results were not as poignant or one-sided. The general populace in statistics did score that thin people gave a higher positive reaction. However, moderate positive reactions were nearly equal. The absolute neutral position where one feels equal toward either size was high and showed that being fat is becoming more acceptable. The lower end preference of fat over thin was low but it was prevalent enough to record. The test findings were about on par with how society views fat and thin people. With the advent of obesity, tolerance for the obese is becoming acceptable. It is unclear whether this is because this is an emerging social norm due to the rise in obesity or if it is an indication that mainstream media is promoting full-size and plus-size models and outfits that flatter fat people. Regardless, the tests show an increasing tolerance for fat
I claim that in American culture, a thin body is held as the "original", normal body; whereas obesity is viewed as a `temporary disruption' to the balance of the body. According to our cultural understanding, an obese body is viewed as being in the process of constant transformation. The idea of a permanently fat person is unacceptable and an obese body must be standardized and normalized. The goal is to transform and
In a way, this book highlights the various consequences of obesity in significant detail. In the author's opinion, obesity does impact on an individual's health negatively from both a surgical and mental
The purpose of this essay is to examine the article " The Fat-Brain Axis Enters a New Dimension," by Joel Elmquist and Jeffery Flier. This essay will attempt to explain this article and summarize its key points.
Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
Obesity is defined as the excessive build-up of body fat that has major detrimental effects on an individual’s health (Caballero, 2007). The major cause of this excess accumulation of body fat is due to a positive energy balance i.e. when the input of energy into the body system exceeds the output of energy which in turn facilitates in weight gain (Caballero, 2007). Obesity is a major health issue in modern day society, firstly because it affects approximately 300 million people worldwide (Weight Management Centre and secondly, drastic alteration in the body’s fat intake also leads to the increasing prevalence of other major health conditions such as cardiovascular disease, stroke, non-insulin dependent diabetes and hypertension (WMC, 2010).
The percentage of fat individuals has become very much all across the world. Over-eating and long rest without any work done are the chief causes of being fat or obese. There are numerous words that are used to designate the condition of fat individuals. Some frequently used words are full figured, over fat, overweight and obese. Almost all individuals use these words alternatively and don’t think that there could be some dissimilarity in the meaning of these words. Let us see, how much the conception of folks is right in terms of difference in the meaning of these words.
The topic that I have chosen to look at is obesity. The aim of this topic is to find out whether “the ignorance of genetics as a contra factor of obesity”. I have chosen to look at this topic because obesity is concerns me. Obesity has always been a bid debate for a long time now and I was intrigued to find out more about the topic and the cause of obesity. The fact that obesity has made deadlines news in recent years. There are a lot of misconceptions about obesity such as overweight is caused by a sow metabolism. There have been a lot of beliefs and myths about obesity in society today and he above myths is on of them. According to Donnellan (1998) ‘ ‘people who are overweight have told their doctors that they eat no more and
Authors conducting studies concerning obesity and how it affects various systems of the body such as the cardiovascular system, have found various ways that excess adipose tissue negatively affect the cardiovascular system. In 2006, Van Gaal et al. identified numerous mechanisms which link obesity and cardiovascular disease (CVD). The main threats to developing a problem with the cardiovascular system related to obesity are a large amount of low-density lipoproteins (LDL) cholesterol, hypertension and glucose metabolism not working as efficiently as capable. LDL is a bad cholesterol because it can build up in one’s arteries and cause the arteries to not function at full potential in delivering blood throughout the body thus putting more strain
This historical research brought Simeon to the analysis and studying of fat in the human body and the various forms it takes on. Simeons establish that the body has three types of fat. The first is structural fat which fills in gaps between organs, and as Simeons puts it, acts as a packing material. It helps protect our arteries, provides bedding for the kidneys and keeps the skin smooth and taut. Structural fat also provides the springy cushion underneath the bones in our feet. The second is normal fat which is our normal reserves of fuel that can be drawn on by the body for energy. Fat packs a high amount of calories in a small amount of space and is used for muscular activity and the overall maintenance of the body including its temperature.
thinness is now a major desirable and acceptable goal; therefore, it would allow an easier
Cardiovascular diseases are the number one factor that can erupt from obesity due to the main causes that it brings, like high blood pressure, and LDL cholesterol to a high count while lowering HDL. LDL is the “bad cholesterol”, and HDL is the “good cholesterol”. We need fats in our body for energy or ATP, in our body. If we get more LDL, it can really be a dangerous case, and
