Introduction
1.1 Body composition analysis through different anthropometric methods
The prevailing system of body composition is primarily focused on model, where the body is composed of two diverse compartments: fat mass (FM) and fat free mass (FFM). Indirect and direct anthropometric measurements can be used to assess nutritional status of particular individual and to determine body composition and distribution of body fat. Different methods have both adventages, as well as limitations. Furthermore, they might provide sources of measurement error. (Ulijaszek, 1999; Willet, 1998; Gibson, 2005)
1.2 Assessment of body composition
The anthropometric practices can measure the FM and FFM and therefore their amount and proportion can be used as determinants of nutritional status at both, the individual and population group levels. In regard, to the increased obesity epidemic and obesity related problems among children and adults in the United Kingdom, the importance of body composition assessment is crucial for short and long term health implications. It can define body fat distribution at individual level and therefore could classify those individuals with overnutrition. The latter, in Public Health significance, the assessment of body composition can help to recognize, in relatively early stage, individuals possibly exposed to both, under- and overnutrition and could influence health outcomes and regarded to overnutrition, prevent further expansion of obesity among population (Gibson, 2005; Reilly, 2003; Wells, 2008; Willet...

(Table 1 with comparison of the methods in Result section state for modifications) Moreover, some factors such as individual’s diet and physical activity, as well as stress factors and menstruation could affect changeability of creatinine excretion. The latter, purpose of longer urine collection period could effect on more precise results to predict individual’s muscle mass. Usually, in practice three sequential 24-hr urine collections should be used, however for the purpose of this study coursework only one day collection was assessed.

Obesity has affected the world in many ways: task forces have been formed to address the issue, people are suffering from health problems due to obesity, and others suffer from psychological and social issues. Nearly two-thirds of the United States population is overweight. There are several ways to determine if a person is obese or overweight. Experts say that a person’s body mass index is the best way to determine an adult’s weight in relation to their height. A BMI of 18.5 to 24.9 kg/m2 is considered normal, adults with a BMI of 25 to 29.9 kg/m2 are considered overweight.
Obesity is a health problem which is growing very rapidly all over the world. Current health articles such as this one, are emphasizing the importance of diet and exercise, to keep a healthy body weight, and to avoid obesity and its consequences at all costs. It is extremely important to make sure one is maintaining a good body weight in order to avoid other complications later on in life.

Nutrition and physical activity are important aspects as they improve health and reduce chronic diseases. In June of this year my family physician placed me on a doctor assisted weight loss program that enabled me to eat my favorite foods but in appropriate proportions and in heathier ways. The best part about Supertracker is that it gives me wonderful tools to support me in understanding and meeting my goals. Once I created a profile through Supertracker I was provided a personal plan to follow including the amount of grains, vegetables, fruits, and protein I needed to be successful. For three consecutive days, I entered my food and activity intake into Supertracker and was able to analyze the excesses and deficiencies
Proper nutrition is important in maintaining a long and healthy life. Most Americans are rushed due to their busy work schedules, and do not take the time to plan their diets properly. Like me, most Americans are unaware of the importance of eating a healthy diet and consume too many foods without the proper nutrients. Throughout my life I have been fortunate. I have not had any major health problems, and have been able to consume most foods without having to worry about gaining weight. These last two years, however, I started to gain weight and have become concerned with my diet. Changing my poor eating habits has been difficult for me, however, having this assignment has taught me that it is not as difficult as I previously imagined.
The onset of obesity is believed to stem from multiple causes, both physiological and environmental. An example of a cause of obesity might include the lack of exercise, however in this review I will foc...
Nutrition assessments include clinical and dietary assessment, anthropometrics, as well as biochemical, laboratory immunologic and functional indices of nutritional status (Gibney, 2005). In epidemiological studies, different dietary investigation tools were designed to assess the nutritional status in individuals and populations, nutrition monitoring and surveillance and diet-disease research (Friedenreich, et al., 1992, Taren, 2002).
Obesity is a physiological condition characterised by an excessive accumulation of body fat, specifically the build-up of adipose tissue beneath the skin. In recent years, the number of people diagnosed with clinical obesity has increased dramatically, with governments desperately trying to tackle the obesity epidemic and its associated consequences (McLannahan and Clifton, 2008). Studies have found that the prevalence of obesity once stood at an estimated 9.8% (Kelly, Yang, Chen, Reynolds & He, 2008), a considerable figure representing almost 400 million individuals worldwide. Even though obesity has now been recognised as a major problem the number of people affected is increasing rapidly, with almost 300,000 deaths attributable to obesity in the USA each year (Allison, Fontaine, Manson, Stevens, & VanItallie, 1999). Excessive amounts of fat can prove dangerous as the condition has a very high comorbidity rate with other long term health issues such as diabetes, cardiovascular disease, hypertension and cancer (Pi-Sunyer, 1993). Numerous examples of media, medical journals and educational literature concerning obesity refer to the condition as a disease, with an increasing use of the word ‘Epidemic’ to describe the somewhat recent surge of obesity cases in western societies (Boero, 2007), however there is little material available that offers evidence for obesity meeting specification for disease. Instead it has been proposed that obesity is alternatively a risk factor for developing other potentially harmful diseases, influenced by a variety of other factors i.e. genetics, cultural ideals and biological impairments.
Since we have been learning about nutrition in class, our task was to record a food log. Nutrition requires a well-balanced diet containing nutrient and vitamins like amino acids and fatty acids. Over the past seven days I have been recording and have been looking very carefully at my intake of nutrients, minerals, vitamins, and fats. In our task, the objective was to record the basic foods we ate during the period of seven, but it did not require recording every single detail or our intake of food. Doing this food log was a pain and it was disturbing because I never wrote about what I ate like breakfast, lunch, dinner, or additional meals. I found this food log useful because it helped me learn what I can change in my intake of foods to make my diet healthy and to see what about my diet is affecting me from being healthy because I could affect me in the future.
There are different ways to determine your body composition and the risks that they involve. In this lab, body measurements are taken to find the body percent fat, waist-to-hip ratio, body mass index (BMI), and basal metabolic rate (BMR). Skin folds for the chest, abdomen, and thigh were taken for males, and triceps, iliac crest, and thigh for females. Age, height, and weight for each person were recorded as well as the waist and hip circumference.
According to Mosbey's Medical, Nursing, & Allied Health Dictionary, Body Composition is defined as the relative proportions of protein, fat, water, and mineral components in the body. It varies as a result of differences in body density and degree of obesity. Basically body composition describes the percentages of fat, bone, and muscle in a persons body. The percentages of body fat a person has determines their overall health and fitness when compared to factors like age, weight, and sex. Body composition also contributes to a persons overall appearance. A healthy male should have about12 to 18 percent of fat. Females should have around 14 to 20 percent. Any thing over or under these percentages would be considered unhealthy.The term's weight and fat are usually used in the same context when discussing physical fitness. Under certain circumstances, being overweight doesn't mean that a person is unhealthy. A person could be in good physical shape but considered overweight because they have excess muscle. People with a lot of muscle mass usually have body weight, which is disproportional to their height. Having a high percentage of fat is unhealthy because it can cause heart disease, high blood pressure, and diabetes.It is important to know your body fat percentage because it can help you put together a realistic exercise program with goals that are attainable. A good exercise program incorporates both aerobic exercises, which burn fat and anaerobic exercises, which build muscle. It is healthier to turn fat into muscle instead of just trying to loose weight without thinking about gaining strength. The best way for a person to change his or her body composition is to improve their fitness levels. Fitness has different meanings to different people. Some people define fitness as having a small waistline. Other people may feel that fitness is the ability to bench-press their body weight ten times.
Obesity occurs in all countries and it is one of the gravest problems in modern society. Obesity problems have become one matter of concern for individuals all around the world. What is more is that Obesity rates continue to rise all around the world. One of the chief causes is unhealthy diets. Obesity is also due to lack of exercise and lack of education and awareness. Therefore obesity has various effects including the risk of suffering from a range of health conditions, increased expenditure on health care and lack of self-esteem.
Proper nutrition is one of the most essential elements to being healthy and living a long life. People deal with food every day, and food has been a part of life since the beginning of civilization. What we eat becomes our diet, and our diet plays a major role in deciding how healthy we are and how well our body functions. Without proper diet, our body cannot carry out the functions it needs to perform. Most people have some common knowledge on what is good and what is bad for the human body to consume. Fruits, vegetables, nuts, and grains are some common items people think of when they think of healthy foods. However, it is not enough just to know what foods are good for your body, it is also important to understand why certain foods are good for you and what they do to help the body function.
