Discuss two or more ways in which eating and satiation are cont\rolled by neural mechanisms One way which eating and satiation are controlled by neural mechanisms is through the Set point theory and Homeostasis – the maintenance of a constant internal environment. KEELEY (1986) proposed that we have a biologically determined standard around which our body weight (specific fat mass) is regulated, hence if we eat too much or too little; homeostatic mechanisms accordingly return us to our original weight. However, PASSER ET AL (2009) found persistent overeating or under eating may make it increasingly more difficulty for homeostatic mechiasms to do this and over time may settle a new weight. Homeostasis controls a dual-feeding system, which when blood the glucose increases the ventromedial hypothalamus is activated, giving you the feeling of being full. When blood glucose decreases the Lateral hypothalamus is activated, giving you the feeling of hunger.
They count calories, may be obsessed over weight loss programmes, repeat weighing and physical examinations, skip meals and use laxatives. Eating disorder 2: Bulimia Nervosa – involves cycles of eating a large amount of calories called bingeing and then getting rid of them by vomiting or laxatives known as purging. Unlike anorexia, people who suffer from bulimia may maintain a steady weight. 1b. Describe the signs and symptoms of the eating disorders you described in Question 1a above.
The Impact of Blood Sugar and Insulin on Dieting Brady Palmer Lock Haven University People, who support weight loss plans, believe that isolating the different causes of obesity and overweight will guarantee weight loss in a short amount of time. By isolating the different causes of weight gain, the supporters of the weight loss plans believe that losing weight will be made simpler for people, who would want to lose weight without devoting too much time for exercise and dieting. The causes of weight gain are determined by a person’s consumption of food and production of hormones. The supporters of weight loss plans feel that limiting the production of certain hormones through the regulation of food consumption can significantly reduce weight loss in comparison to exercise and dieting. Insulin is a hormone that significantly contributes to weight gain (Hertzler & Kim, 2003).
While I would be playing games, conversing with friend's, and eating pizza, my hypothalamus would be at work regulating many of the bodily functions that I have. The hypothalamus is a part of the body that is responsible for keeping all of the systems in the body functioning normally. So the hypothalamus would keep my heart beating and my body temperature constant. The main way the hypothalamus would be involved would be when I am eating pizza. The hypothalamus is responsible for regulating the feeling of hunger.
A carb controlled diet allows diabetics more choices of food. Controlling carbs in your diet can help you lose weight. Carbs can be found in many different foods such as baked foods, corn, rice, cereals, dairy, fruits, vegetables and whole grains. Some carbs can cause a higher rise in blood sugar levels then in others. The reason that carbs can help you lose weight is because of the effect on blood glucose.

Discuss psychological explanations of one eating disorder (8+16 marks) The DSM defines eating disorders as ‘illnesses in which the victims suffer severe disturbances in their eating behaviours and related thoughts and emotions’. It is argued that the preoccupation with food in many Western cultures, coupled with the obsession of losing weight has led to the emergence of food and eating disorders such as Anorexia Nervosa (AN). As society has developed its understanding of the causes of eating disorders, it has become apparent that they are as much a mental disorder as they are a physical disorder. Thus psychological explanations have emphasised the risk factors of media, culture, personality and childhood experiences in the cause of Anorexia Nervosa. The DSM (IV) states four criteria for AN.
Naeema Goni Discuss two or more explanations for the success and failure of dieting (8 + 16 marks) Dieting has become an extremely popular method to use in attempt to change body size and shape in order to fit in with the thin western ideal of beauty. The first method explaining the impact of dieting is the restraint theory, Herman and Mack (1975) suggest that by restraining our food intake we actually increase the risk of overeating, which is explains why many diets fail and some people even end up putting more weight on. Herman and Polivy (1984) created the boundary model to explain this in further detail, this model suggests that dieters have a larger range between their hunger and satiety levels, so it takes them longer to feel hungry and they need to eat more food to be satisfied, dieters have a desirable food intake level that they self-impose but when they perceive themselves to go over that level they experience the disinhibition effect and continue to eat until satisfied. This disinhibition of behaviour after the self-imposed limit is overstepped the ‘what the hell effect’ comes into action. The dieter who eats more than their self-imposed limit begins to feel a sense of ‘why bother?’ Once this is overcome the ‘what the hell’ effect takes over and eating is disinhibited and they feel that they might as well carry on.
This paper will explain binge eating behavior through the psychoanalytic perspective of Sigmund Freud and the humanistic perspective of Ryan and Deci. And then each perspective will be critically evaluated in its capability to explain binge eating behavior in people. Binge eating behaviour in people is characterised by compulsive overeating, in which a person ingests a large amount of food during a discrete period of time, while experiencing a lack of control and feeling powerless to stop eating (Mayo Clinic, 2012). People who binge eat, often eat in the absence of hunger and continue eating long after they are full. People who binge often gorge in isolation.
Recent medical research has shown that healthy eating habits can curb many of the symptoms associated with Irritable Bowel Syndrome. Abdominal pain, bloating and discomfort are some of the main symptoms. Other symptoms may include constipation diarrhea. Reducing the amount eaten at meals and the level of digestive tract stimulants taken in has a large impact on these common symptoms. Though this will not eliminate the symptoms all together, they will have a noticeable effect.
