Your BMI is calculated from your current height and weight. For most people, the higher their BMI, the more body fat they have.

The Skinny on Fat: Good Fats vs. Bad Fats So you might assume that fat is to blame for the obesity epidemic now plaguing our nation. Actually, fat is only part of the problem. Obesity is much more complicated than just overeating a single nutrient. Eating more calories -- from fats, carbohydrates, protein, and alcohol -- than you burn off leads to weight gain. Simply put, people who get little physical activity and eat a diet high in calories are going to gain weight. Genetics, age, sex, and lifestyle also weigh into the weight-gain formula.

Does Obesity Matter? The problem here is that we are not distinguishing between symptom and cause. Obesity is caused by the same behaviors that cause cardiovascular disease and type 2 diabetes.

AICR: Washington, DC). AICR/WCRF was the first organization to note that, after smoking, obesity is the most important preventable cause of cancer. While obesity is clearly linked to risk for developing many forms of cancer, the deleterious impact of obesity on prognosis has proven even more compelling in several studies.

Childhood Obesity The causes of obesity are complex and include genetic, biological, behavioral and cultural factors. Obesity occurs when a person eats more calories than the body burns up. If one parent is obese, there is a 50 percent chance that their children will also be obese. However, when both parents are obese, their children have an 80 percent chance of being obese. Although certain medical disorders can cause obesity, less than 1 percent of all obesity is caused by physical problems. Obesity in childhood and adolescence can be related to: poor eating habits

Obesity Causes Obesity Causes. Many factors influence body weight-genes, though the effect is small, and heredity is not destiny; prenatal and early life influences; poor diets; too much television watching; too little physical activity and sleep; and our food and physical activity environment. The causes of obesity are as varied as the people it affects. At its most basic, of course, obesity results when someone regularly takes in more calories than needed. The body stores these excess calories as body fat, and over time the extra pounds add up. Eat fewer calories than the body burns, weight goes down.

Morbid Obesity If those calories are not used, the body stores them as fat. Your body will build up fat stores if you continue to eat more calories than your body can use during daily activities and exercise. Obesity and morbid obesity are the result of too much fat being stored in your body. Certain medications, such as antidepressants, can cause weight gain. Medical conditions such as hypothyroidism can also lead to weight gain, but can usually be managed so that they do not lead to obesity.
