  • The Mono-Genetic Model Of Obesity

    716 Words  | 3 Pages

    Studies in animals have also suggested that obesity has a genetic component. Several ‘mono-genetic’ and ‘poli-genetic’ models of obesity are based on animals. These models are used to stimulate what happens when some chemicals are not produced (like leptin in the ‘ob-ob’ mouse), or when some receptors (like leptin receptors) are reduced or malfunctioning. The set-point theory (Kennedy 1953: Nisbett, 1972) states that after dieting to reduce body weight, an animal eats more and is less dependent on

  • Childhood Obesity Genetic Factors

    contributions to child hood obesity. Genetic factors is one contribution to childhood obesity, but while genetics is a factor it is not the main factor in childhood obesity. Genetic factors cannot be the main contributor to the obesity because of the major increase in obesity in children cannot all be contributed to genetics. There has to other environmental factors mixed with the genetic factor to make the child extremely over weight or obese unless the child has a genetic disorder like Prader-Willi

  • Genetic And Environmental Factors Of Obesity Epidemic

    542 Words  | 3 Pages

    An obesity epidemic is when there is a constant rise in the number of cases of obesity among a population. Each person in the United States has a different reaction to the types of food they consume. Obesity is influenced more by environmental factors but can also be influenced by genetic factors. Environmental factors include lack of physical activity, individual response to food, the environment itself, television consumption, the ability to super size meals, and consumption of large portion meals

  • Childhood Obesity And How Genetic, Social And Environmental Factors Help The Problem Of Obesity

    970 Words  | 4 Pages

    Obesity is now considered an epidemic stated by Hall and Elliman (2010) they also declared how around one to two thirds of children will go onto become obese. To be able to avert obesity there needs to be an understanding of what elements can cause obesity, but also to understand the harm it can have on the health and wellbeing of the child, this allows people to support children with the condition. This essay will delve deeper into this in relation to childhood obesity and how genetic, social and

  • Is Obesity the Result of Genetics or Merely the Lack of Physical Exercise?

    535 Words  | 3 Pages

    in the search to discover if obesity is the result of genetics or merely lack of physical exercise and poor eating habits. A peer-reviewed article by A Li and D Meyre entitled, Challenges in Reproducibility of Genetic Association Studies: Lessons learned from the Obesity Field, mentions that genetics does have a substantial role in obesity, but since scientists cannot reproduce the gene and prove that it is true, they cannot guarantee that genetics is a result of obesity (Li & Meyre, 2012). A similar

  • Relationship between Genetic Suceptibility, Obesity, and the Development of Type 2 Diabetes

    1133 Words  | 5 Pages

    TYPE 2 DIABETES MELLITUS (T2DM) This type of diabetes commonly occurs in the later stage of life but due to increase in obesity; it also occurs in young adult. Type 2 diabetes can be defined as insulin resistant and insulin deficiency in the blood stream. OBESITY Obesity can be defined as been overweight with excess accumulated body fat by subcutaneously and viscerally; resulting in a high body mass index (BMI) which has negative effects on health (Taylor et al, 2010). BMI is defined by dividing

  • Human Genes Related to Obesity

    672 Words  | 3 Pages

    Human genetic traits are ultimately classified as either monogenic or complex (Celedon, Hunninghake, 2012). As suggested by their names, monogenic traits are primarily influenced by alterations of a single gene (Celedon, Hunninghake, 2012). On the other hand, complex traits are a result of variations in multiple genes, as well as the contributions of various environmental factors (Celedon, Hunninghake, 2012). One such complex trait, which has become quite omnipresent in the modern world, is adiposity

  • A Brief Note On Prader Willi Syndrome ( Pws )

    1358 Words  | 6 Pages

    Prader-Willi Syndrome (PWS) first was recognized in 1956 by three Swiss doctors, Andrea Prader, Alexis Labhart, and Heinrich Willi. PWS is a genetic disorder that is present at birth and causes many different cognitive, physical, and behavioral problems. This is a result of an abnormality of chromosome 15, which is one of the most complex regions of the human DNA system. This disorder affects about one out of every fifteen thousand births in both males and females. It doesn’t particularly reach to

  • Behavioral Genetic Determinism: Do Genes Equal Behavior? Essay

    2523 Words  | 11 Pages

    Behavioral Genetic Determinism: Do Genes Equal Behavior? Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single

  • Essay on What´s Prader-Willi Syndrome?

    738 Words  | 3 Pages

    Syndrome, named after the doctors who described it in 1956, is a rare genetic mutation involving missing genes on chromosome 15. The syndrome has two distinct stages and affects the growth and development in patients diagnosed with the disorder. The most major symptom of this disorder is the irregular appetite causing severe weight gain. Prader-Willi syndrome is the most common genetic cause of life-threatening childhood obesity and affects a patient for their entire life span. The syndrome occurs
