The human body has a lot of fat in it. They can be stored in specialized cells called adipocytes.Their main function is to fill energy reserves in the body. These cells accumulate energy in the form of lipids which are released back to the body when energy is needed.adipocytes are basically small accumulations of fat that are encased by fibrous connective tissue between muscle and the dermis (deep layer of skin). When these adipocytes begin to store more energy (fat) than is used by the body they grow bigger and body fat begins to accumulate. Fatty acids and glycerol are converted into triacylglycerols which are stored within the adipocytes primarily as an energy store. When energy is required to do work such as anabolism, triacylglycerols …show more content…
Fat in normal women represents between 18% and 20% of body weight, whereas in men it represents only 10% to 15%. The reason for this difference is that women at some point in their lives may nourish a fetus and then a baby from their own reserves. So women have to stock energy in the form of fat in anticipation of future pregnancies. Females tend to store fat on the hips, thighs and buttocks, giving them more of a pear shape. This female pattern is also called gynoid, or gluteal-femoral pattern obesity.The body fat percentage in a healthy, active, athletic woman ranges between 18% and 20%.For most average women who are less active the body fat percentage is much higher. Fat is stored deep in the body cavities, and directly beneath the skin called subcutaneous fat. Men find fat in fat cells from the man's back, flanks, and stomach. Men collect most weight the waist and over the ab muscles. Our bodies need these fat reserves as energy sources and insulation as well as to cushion our internal organs. At no time should an individual attempt to rid their body completely of
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
This is a chemical process of the cells which is known as metabolise. The metabolise cells have a mitochondrion which releases energy to help the metabolise to break down complex organic molecules into simple molecules and energy which is known as catabolise. This how the body burns fats from your body as it is broken into small molecules and energy were the body uses the nutrients from the food you have eaten to use for other body parts to functions. If you eat more food that doesn’t match the energy reequipments this can cause you to store fats in your body making you weigh
It doesn’t contain blood vessel and is nourished by the diffusion from the bone. Adipose, is another term for fatty tissue. It is common for under the skin and around the organs such as the heart, kidney and part of the digestive tract.
The pathophysiology of obesity is when there is a buildup of excess body fat. This excess body fat is determined by calculating a person body mass index (BMI). The BMI is calculated by an individual’s weight in kilograms divided by the square of a person’s height in metersthis allows us to come up with appropriate range of weight to an individual’s height. The body mass index is used to find out if an individual is overweight or obese. Individuals who’s BMI that have a range of 25 to 29.99 are thought to be pre- obese and overweight When an individual body mass index has surpassed 30kg this person is considered obese. As an individual’sBMI increases they become part of a different class of obesity there’s class I which is 30-34.9, class II
In this study, they investigated the social spread of obesity by performing a quantitative analysis on 12,067 people that were a part of the Framingham Heart Study. Longitudinal statistical models were used to assess the effect of another person’s weight gain on an individual. They found that a person was 57% more likely to gain weight if they had a friend who became obese, 40% more likely if their sibling became obese, and 37% more likely if their spouse became obese. Hence, obesity seems to be influenced by social factors. This study seems like a reliable source as it was published by the New England Journal of Medicine in 2007.
Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Currently the number of obese children is increasing in our country and it is a problem that should be concerned. Doctors often use a formula based on height and weight, called body mass index (BMI), to determine obesity. Children with a BMI over 21 is considered obese and over 18 is overweight (Arnett, J.J.2016). Adults with a BMI of 30 or more are considered obese. Severe obesity, also known as severe obesity or morbid obesity, occurs when a BMI of 40 or more is present. With morbid obesity, there may be serious health problems. If children do not have enough activities, they will

The average woman has more body fat than men. The comparison between the normal body fat with weight loss is around 25-30% in women and 18-23% in men. Women with a body fat of more than 30% body fat and men with more than 25% are considered obese. Or in other words someone who has a weight of 20% higher than the value of the middle of the range of a normal weight, are considered obese.
Obesity is a disorder involving unwanted body fat that increases health risks. It has been a huge concern in America. Currently about more than half of America is either obese or overweight. Obesity affects the body in a wrong way. It has caused type 2 diabetes, heart disease, high blood pressure, stroke, high cholesterol, Gallbladder disease, and some types of cancer. Due to these diseases, there have been approximately 400,000 deaths in America. Childhood obesity is the worse. It has almost doubled in that age group in the past 30 to 35 years. Weight gain results from in taking unwanted calories and carbohydrate. Although obesity has been caused through the availability of cheaper, processed, and malnourished foods and school
Looking for an interesting article to read for this week’s journal assignment, the article “The Hidden Dangers of ‘Skinny Fat’” by Sifferlin (2014) caught my eye from Time.com. The article basically says that we are focusing too much on weight as guide for health since even skinny people get diabetes and cholesterol problems, so yearly exams are the only way to measure your health (Sifferlin, 2014).This article really caught my attention, because I remember New York efforts to ban large servings of sodas at certain venues a few years ago to fight obesity and searching our Uopeople library I found “Will sugary drink restrictions help New York win the war on obesity?” by Grynbaum (2012). I always found it interesting that politicians always try
Obesity basically means having too much body fat. Not being overweight for your height, having too much muscle, or water in your body. What exactly is obesity? “Obesity is a condition that is associated with having an excess of body fat, defined by genetic and environmental factors that are difficult to control when dieting. Obesity is classified as having a Body Mass Index (BMI) of 30 or greater. BMI is a tool used to measure obesity. Obesity increases your risk of developing related conditions such as diabetes, hypertension and sleep apnea, to name a few. Many individuals are affected by obesity and are not aware of it” (O.A.C, 2016). Causes of obesity vary from person to person, but most are from the same reasons. Taking in more calories than your body can burn leads to obesity because your body stores the unused calories as fat. Typical causes are eating too much food than your body can use, drinking too much alcohol, and not getting enough exercise. Many obese people who lose large amounts of weight and gain it back think it is their fault. They blame themselves for not having the willpower to keep the weight off. Many people regain more weight than they lost. Today, we know that biology is a big reason why some people cannot keep the weight off. Some people who live in the same place and eat the same foods become obese, while others do not. Our bodies have a complex system to help keep our
If an individual consume high quantity of energy from the diet, mainly from fat and sugars, however do not burn off the energy through activities or physical exercises, majority of surplus energy is then stored by the body known as fat.
Obesity refers to the condition of having an extra amount of body fat. Obesity is caused by eating too much and moving too little. When an individual’s amount of body fat becomes too high, they are at a greater risk of being affected with life changing diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, and others. This shows that people should become more physically active and attempt to make healthier choices because their life depends on the decisions, they make.
The everyday routines of life can and will be more difficult if encumbered with obesity.
Obesity is a condition in which the over accumulation of adipose fat tissue causes the weight of a person to increase abnormally. Their weight exceeds by 20%, as a factor of their ideal body weight. According to recent analysis, statistics show that more than one third of the world’s population is targeted by obesity. Research shows that overweight and obesity kills more people than underweight. Obesity occurs greatly amongst adults who are 18 years or older. An estimated 600 million adults were obese out of the 1.9 billion that were overweight, around the world in 2014. One in three adults in Mexico, New Zealand and United States are obese, and one in four adults in Australia, Canada, Chile and Hungary are obese. In contrast, rates of obesity are much lower in Asian countries, where approximately 2-4% of adults have obesity. In countries such as Mexico and the United States, Latino and Africans have the highest rates of obesity amongst all the individuals. However, along with adults, statistics show that the rates for obesity are also high among children within and below the age of 5. As calculated in 2013, the number of children across the world that were either overweight or obese was 42 million. Since then, the rates have increased by 30% more in in low- and middle-income countries than in developed countries. Due to the fact that this condition continues at higher rates across the world, several organizations, such as the World Health Organization, are working with and
