Explanation:
In the United States today, about _one-third_ of the population is obese, and this number is _rising_. A 2007 study titled "The Spread of Obesity in a Large Social Network Over 32 Years" showed that obesity was _contagious_.
Obesity is a medical condition in which excess body fat has accumulated to an extent that it may have a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight by the square of the person's height, is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Obesity increases the likelihood of various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, osteoarthritis, and depression.
