Essay about Anti-Obesity Effects of Polyunsaturated Fatty Acids

The overconsumption of inappropriate foods containing trans-fats and large serving portions has caused many to become obese hence developing heart disease, and diabetes among other preventable disease. Currently over 500 million of the world population is obese and one and half billion people in the world are overweigh”. Every year about 2.5 million deaths are related to obesity (WHO) and children seem to be the most affected. Furthermore, obesity has continued to increase and currently there are more obese people in the world than underweight. Amazingly, the United States a country with ample resources has the higher rate of obese

Obesity remains an extremely serious issue worldwide. Once considered a problem for wealthier counties, overweight and obesity are now dramatically increasing in low and middle income countries (WHO, 2011). In American, the rates of obesity continue to soar. CDC (2009) recognizes obesity as a risk factor for diabetes, heart disease, high blood pressure, and other health problems. According to NHANES over two-thirds of the US are overweight or obese, and over one-third are obese (CDC, 2009). Treatment for this illness varies; it may include the incorporation of diet, exercise, behavior modification, medication, and surgery. Since there is no single cause of all overweight and obesity, there is no single way to prevent or treat overweight

The dangers of the obesity epidemic are overwhelming and the percentage of the population which suffers from this condition is increasing exponentially with the increased use of HFCS. Especially in the United States, where almost a third of the adult population is obese, the problems with obesity are readily becoming more apparent. Researchers predict that about 30 serious medical conditions can arise due to obesity. Some of these complications are type II diabetes, high blood pressure, coronary heart disease, and arthritis. Problems can also extend to hypertension, birth defects, increased chances of various cancers, and impaired mobility.

Although the mechanism of obesity development is not fully understood, it is confirmed that obesity occurs when energy intake exceeds energy expenditure. There are multiple etiologies for this imbalance, hence, and the rising prevalence of obesity cannot be addressed by a single etiology (Dehghan et al., 2005, p.

This topic of obesity has been a rising issue for many years. There are many different reasons and predictions as to why the number for this disease is rising in America. Recent epidemiologic studies of diet and health outcomes including obesity have changed the focus to the overall diet quality and dietary pattern instead of single nutrients, such as dietary fat (Hu et al, 2000; Fung et al, 2001a, 2001b). The process starts with the lack of physical exercise and the food that people eat. As Americans, we need to picture more healthier foods to eat, have more physical activity to help food digest easier and faster. According to Campbell “to date, interventions have focused on improving the more amenable determinants of obesity: physical inactivity

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.

Obesity is the next major epidemiologic challenge facing today's doctors, with the annual allocation of healthcare resources for the disease and related comorbidities projected to exceed $150 billion in the United States. The incidence of obesity has risen in the United States over the past 30 years; 60% of adults are currently either obese or overweight. Obesity is associated with a higher incidence of several diseases, including diabetes, cardiovascular disease, and cancer. Consumption of fast food, trans fatty acids (TFAs), and fructose—combined with increasing portion sizes and decreased physical activity—has been implicated as a potential contributing factor in the obesity crisis. The use of body mass index (BMI) alone is of limited utility

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).

Obesity, the condition of being severely overweight, is a serious issue in the United States that is gradually beginning to affect more and more citizens. In recent years, the number of Americans suffering from this chronic disease has significantly increased. Researchers have found that nearly one third of the U.S. population is considered overweight and, on average, three hundred thousand individuals die yearly as a result of obesity (Hollands et al. 2). When one participates in little to no physical activity and their diet consists mostly of high fat foods, chances are they will gain weight. If someone becomes obese, they may develop serious health related issues that, in some cases,

Many studies have shown that high VF is significantly related to insulin resistance [11]. Normal weight individuals with low subcutaneous fat, but increased VF had greater insulin resistance than those with lower VF [8]. When evaluating this relationship in obese, metabolically at risk obese had more VF and greater insulin resistance than MHO [5]. On the other hand, subcutaneous fat seems to be associated with increased levels of leptin [11], a hormone secreted by adipose tissue that signals the amount of energy stores (fat mass) available in the body [12]. Leptin levels are positively correlated with FM [12], with obese individuals exhibiting high leptin concentrations [11]. Since obese individuals have an excess of body fat, high concentrations of leptin should decrease energy intake and increase energy expenditure which would promote a return to normal weight. Despite the potential physiological function, the role of leptin in energy expenditure is not completely understood. Research has demonstrated obese individuals to have high

It was merely a decade ago that the obesity epidemic was thought to only be a minor problem and had only alarmed a small number of endocrinologists interested by the size of the situation (James, 2008). However today, the problem of obesity is vast with more awareness of its presence by doctors and individuals alike. In fact, the Center for Disease Control and Prevention states, “More than one-third (34.9% or 78.6 million) of U.S. adults are obese (CDC, 2014)”. These numbers are outrageous and eye opening, leaving millions looking for a solution to this troubling epidemic. Obesity is not simply a cosmetic flaw as some might think, but is actually a very dangerous state of being for any individual to sustain long-term. Mentioned further in

While the persistent popularity of fish oil may reflect the human weakness for anything touted as a life-extending elixir, it also reflects that, even among scientists, diet notions can persist even when stronger evidence emerges contradicting them. Scientists, sometimes, are reluctant to let go of

Obesity in the United States has more than doubled over the past four decades. Prevalence of obesity cause many other disease such as diabetes and heart issues. Obesity can be described as a health condition of a person or people of a population that have excess body fat. Diabetes is a disease related to high level of blood sugar in the blood. Obesity and diabetes are among disease that have direct relationship with each other. As obesity increase in a population, diabetes increases too. Jennifer B.Marks, Professor of Medicine at the University of Miami Miller researches in “Obesity in America: it’s getting worse”, Roger Z. Joanne a public health provider in the Obesity Action Coalition group researches in “Obesity and type 2 Diabetes”, Eckel H. Robert, Professor of Medicine in Colorado University researches in “Obesity and Type 2 Diabetes: What can be Unified and What needs to Be Individualized”, and Obesity Society group researches in “Your weight and diabetes”, mention that while obesity and diabetes have different definition in medical process, the reason why people become obese and diabetic as well as how to prevent them is same. Eating larger portion size than what the body needs , lack of physical activity, and putting foods without good quality in diet are the major reasons that people become obese.

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
