Introduction to weight loss

Whether you are trying to lose 5 pounds or more than 50, the same simple laws of physics determine whether or not you will lose weight and how fast your weight loss will occur. Remembering these simple guidelines and putting them into practice can lead to weight loss without the aid of any special diet plans, books, or medications.

Our weight is determined by the amount of energy that we take in as food and the amount of energy we expend in the activities of our day. Energy is measured in calories. If your weight remains constant, you are probably taking in the same amount of calories you burn each day. If you're slowly gaining weight over time, it is likely that your caloric intake is greater than the number of calories you burn through your daily activities.

Obese people have an overall mortality rate almost twice that of non-obese people. They are more than three times as likely to develop diabetes. Obesity is associated with unhealthy cholesterol levels and impaired heart function. It is estimated that if all Americans had a healthy body composition, the incidence of coronary heart disease would drop by 25%. Other health risks associated with obesity include hypertension, many kinds of cancer, impaired immune function, gallbladder and kidney diseases, and bone and joint disorders. These risks from obesity increase with its severity, and they are much more likely to occur in people who are more than twice their desirable body weight.

The effects of obesity on health were further clarified by the Nurses' Health Study, in which Harvard researchers have followed more than 120,000 women for over 16 years. It found that even mildly overweight women had an 80% increased risk of developing coronary heart disease compared to leaner women. This study also confirmed that to reduce the risk of dying prematurely of any cause, maintaining a desirable body weight is important.

The distribution of body fat is also an important indicator of future health. People who tend to gain weight in the abdominal area ("apples") have a risk of coronary heart disease, high blood pressure, diabetes, and stroke twice as high as those who tend to gain weight in the hip area ("pears"). The reason for this increased risk is not entirely clear, but it appears that fat in the abnomen is more easily mobilized and sent into the bloodstream, increasing disease-related blood fat levels.

In addition to risking physical health, obesity can impair psychological health. Being perceived as fat can be the source of ridicule, ostracism, and sometimes discrimination from others; it can contribute to psychological problems such as depression and low self-esteem. For some, the stigma associated with obesity can give rise to a negative body image, body dissatisfaction, and eating disorders such as anorexia and bulimia.
