Causes of Obesity (Pt.2)
*information obtained from African-American Healthy by Richard Walker Jr, M.D
The simple cause of obesity is an increase in the consumption of high-calorie foods with a decrease in physical activity. In other words, you eat more than your body burns, and your body stores the excess as fat.
DID YOU KNOW: there is a direct link between visceral obesity and heart disease, hypertension, type 2 diabetes, as well as certain types of cancer. However, an overabundance of fat cells promotes insulin resistance which can lead to type 2 diabetes; which leads to inflammation, hypertension, and kidney disease.
Fat cells also disrupt your hormone levels and this disruption results in inflammation and high blood pressure. Obesity places a tremendous strain on your heart muscle, which can eventually cause a heart attack.
Excess body fat can increase the production of a cancer-promoting estrogen called estrone, which along with inflammation could lead to cancer (prostate, breast, kidney and uterine)
Many diseases are interconnected by this single factor called excess body fat
While low energy expenditure certainly has a lot to do with weight gain, there are other factors that play a role in being overweight, including stress, poor thyroid function and environmental toxins.
Your body has minimum energy requirements to function properly. The number of calories required to maintain the physiological processes of non-active human body is referred to as resting energy expenditure (REE)
The energy needs of your various organs account for about 70 percent of that number, with 20 percent used for non-exercise related physical activity, and the remaining 10 percent used to generate body heat. When you take in more calories then dictated by your daily caloric requirement without also raising your energy level through physical activity, the excess calories are stored as fat, thus resulting in weight gain and possible future obesity.
Lastly, the lack of exercise is actually a double-edged sword. It first promotes the formation of fat, which than has an effect on the hormones that regulate appetite.
