What is Obesity?

Excess weight and body fat increases ones’ risk for particular health conditions, which will be explored in the consequences of obesity.

Today more than one-third of adult Americans over the age of twenty are overweight or obese. Sadly, these percentages are growing fast in all age categories, including children; roughly 30 percent of American children, even as young as two years old, are obese.

Worldwide, 1.5 billion adults and nearly 43 million children under the age of five are considered overweight, and in today’s world being heavy kills more people than being underfed.
