Sleep Apnea
Sleep apnea is a condition in which a person stops breathing for short periods during the night. A person who has sleep apnea may suffer from daytime sleepiness, difficulty concentrating, and even heart failure.

The risk for sleep apnea is higher for people who are overweight. A person who is overweight may have more fat stored around his or her neck. This may make the airway smaller. A smaller airway could lead to difficult breathing and loud snoring. In addition, fat stored in the neck and throughout the body may produce substances that cause inflammation.

Immune System & Cancer
Cancer occurs when cells in one part of the body, such as the colon, grow abnormally or out of control. The cancerous cells sometimes spread to other parts of the body such as the liver. Cancer is the second leading cause of death in the United States.

Being overweight may increase the risk of developing several types of cancer, including cancers of the colon, esophagus, and kidney. Being overweight is also linked with uterine and postmenopausal breast cancer in women. Gaining weight during adult life increases the risk for several of these cancers, even if the weight gain does not result in overweight or obesity.It is not known exactly how being overweight increases cancer risk. It may be that fat cells release hormones that affect cell growth, leading to cancer. Also, eating or inadequate physical activity may lead to being overweight which also may contribute to cancer risk.

Cardiovascular Disease
Cardiovascular heart disease means that the heart and circulation (blood flow) are not functioning normally. Often, the arteries have become hardened and narrowed. If you have coronary heart disease, you may suffer from a heart attack, congestive heart failure, sudden cardiac death, angina (chest pain), or abnormal heart rhythm. In a heart attack, the flow of blood and oxygen to the heart is disrupted, damaging portions of the heart muscle. During a stroke, blood and oxygen do not flow normally to the brain, possibly causing paralysis or death. Coronary heart disease is the leading cause of death in the United States, and stroke is the third leading cause.

People who are overweight are more likely to develop high blood pressure, high levels of triglycerides (blood fats) and LDL cholesterol (a fat-like substance often called bad cholesterol), and low levels of HDL cholesterol (good cholesterole). These are all risk factors for heart disease and stroke. In addition, excess body fat especially abdominal fat may produce substances that cause inflammation. Inflammation in blood vessels and throughout the body may raise heart disease risk.

Losing 5 to 10 percent of your weight can lower your chances for developing coronary heart disease or having a stroke. Weight loss may improve blood pressure, triglyceride, and cholesterol levels. It also improves heart function and blood flow, while it decreases inflammation throughout the body.

Type 2 Diabetes
Type 2 diabetes is a disease in which blood sugar levels are above normal. High blood sugar is a major cause of coronary heart disease, kidney disease, stroke, amputation, and blindness. Type 2 diabetes is the most common type of diabetes in the United States. This form of diabetes is most often associated with old age, obesity, family history of diabetes, previous history of gestational diabetes, and physical inactivity. The disease is more common among certain ethnic populations. How is it linked to overweight? More than 85 percent of people with type 2 diabetes are overweight. It is not known exactly why people who are overweight are more likely to develop this disease. It may be that being overweight causes cells to change, making them resistant to the hormone insulin. Insulin carries sugar from blood to the cells, where it is used for energy. When a person is insulin resistant, blood sugar cannot be taken up by the cells, resulting in high blood sugar. In addition, the cells that produce insulin must work extra hard to try to keep blood sugar normal. This may cause these cells to gradually fail.What can weight loss do? You may lower your risk for developing type 2 diabetes by losing weight and increasing the amount of physical activity you do. If you have type 2 diabetes, losing weight and becoming more physically active can help you control your blood sugar levels and prevent or delay complications. Losing weight and exercising more may also allow you to reduce the amount of diabetes medication you take. The Diabetes Prevention Program, a large clinical study sponsored by the National Institutes of Health, found that losing just 5 to 7 percent of your body weight and doing moderate-intensity exercise for 30 minutes a day, 5 days a week, may prevent or delay the onset of type 2 diabetes

Gallbladder Disease
Gallbladder disease includes gallstones and inflammation or infection of the gallbladder. Gallstones are clusters of solid material that form in the gallbladder. They are made mostly of cholesterol and can cause abdominal pain, especially after consuming fatty foods. The pain may be sharp or dull.

People who are overweight have a higher risk for developing gallbladder disease. They may produce more cholesterol (a fat-like substance found in the body), a risk factor for gallstones. Also, people who are overweight may have an enlarged gallbladder, which may not work properly.

Lesson 2

Identify the the four major weight assessments used today and summarize their application in creating a healthy weight range.
Choose a realistic target weight range based on your metabolic rate, activity level, eating habits, and assesssments.

Are You at Risk?

By now, you know the health risks involved with being overweight. But how do you determined what a healthy weight range is for you? In this lesson you will discover the different methods for assessing weight and create an assessment profile specifically for you.

“Obesity appears to be linked with an increased risk of depression, say researchers, and the link also works in the other direction. We found bidirectional associations between depression and obesity: obese persons had a 55% increased risk of developing depression over time, whereas depressed persons had a 58% increased risk of becoming obese."


Depression Sleep Apnea Immune System Cardiovascular System Diabetes Gallbladder Disease The Different Assessments

The four most common methods of assessing weigth are: Body Mass Index (BMI), Waist/Hip Ratio, Height/Weight Chart and Percent Body Fat. Unfortunatley, one test does not work for everyone. When we speak of weight, it is recommended that we try to determind a weight range and not a specific number. Remember, the idea is to be healthy and reduce the risk of disease, not necessarily to be thin. Let's look at the various types of assessments and their unique qualities...
