Topic > describe the role of diet in preventing underweight, overweight and obesity. Having a good diet and incorporating a regular exercise routine will help keep someone underweight and healthy, your immune system will be in much better shape to fight off colds and germs, your heart would also be in better shape to help pump blood into the whole body. If a person eats a good diet, I don't think they will have any problems being overweight, underweight, or obese. Underweight means a person whose weight is less than the average person's weight, for example I am in the military, I am five feet tall and weigh 130 pounds, so I gain weight, however if I weighed 121 pounds or less I would be considered underweight. Overweight is someone who is above the average of what people consider a desirable weight, obese is someone who is truly overweight. If a person is overweight or obese they are at risk of having a stroke, diabetes or even heart disease, heart failure because unhealthy foods can build up in the arteries and cause them to become blocked, thus causing serious health problems. Being underweight means a person needs to eat more proteins and nutritious foods and can suffer from depression, heart problems (yes, even if they are underweight), and brittle bones. Being underweight increases your chances of fractures and can also cause fertility problems in both men and women. Having a high percentage of body fat can put you at a higher risk of developing high blood pressure, high cholesterol and some cancers.
