Eating an unbalanced diet will affect the body in various ways. Ill health is often a symptom of an individual's poor diet and is demonstrated through conditions such as obesity, fatigue, diabetes and anorexia. A diet high in animal fat is one of the main causes of poor health in the Western world, often leading to obesity and heart disease. Anorexia and bulimia are also becoming increasingly prevalent and are known to damage the body's immune system and vital organs.
Obesity and Heart Disease
Eating a diet high in saturated fat increases an individual's risk of heart disease, a leading cause of death and debilitation worldwide. According to the Weight Loss Resources website, obesity is often linked to heart disease since overweight people are more likely to suffer from high blood pressure. The website also cites high levels of cholesterol in the blood and triglycerides (blood fats) as other causes of heart disease linked to obesity.
An individual suffering from anorexia nervosa tends to exclude all types of fats from her diet. As a result, the sufferer becomes deficient in essential protein, vitamins and minerals which are found in milk and dairy produce, along with meat and fish. According to the Help Guide website, the severe calorie restriction of anorexia has devastating physical effects. The body goes into starvation mode, slowing down to preserve energy. It then begins to consume itself, resulting in the loss of more body fat and the damaging of organs such as the intestines, kidneys and heart.
Type 2 Diabetes
Poor eating habits increase an individual's chance of developing type 2 diabetes. Obesity is a risk factor for the disease, meaning that those living on high-calorie diets are most susceptible to the condition. According to the UMM website, diabetes can damage the heart, kidneys, eyes and nerve endings and can also increase a person's risk of suffering from a stroke, developing high blood pressure, blindness or kidney disease.
Failure to eat a balanced, nutritional diet can lead to fatigue. According to the ABC website, iron is a key ingredient to maintain energy levels. Nevertheless, many people are deficient in iron, causing them to experience tiredness and lethargy. The website also cites dehydration as a major cause of fatigue, in addition to obesity.
