America's bad reputation for obesity is not getting any better.

The CDC just released the latest obesity data from the National Health and Nutrition Examination Survey — the 2011-2012 year. The survey examines about 5,000 people each year and asks a series of socio-economic and health-related questions and includes a physical exam, giving us a frightening look at just how fat Americans really are.

The CDC defined obesity as individuals having a body mass index greater than or equal to 30. Body mass index is calculated by weight in kilograms divided by height in meters squared.

Here are five most worrying facts:

1. Almost 35% of adults in the U.S. are obese.

2. Obesity rates were higher among middle-aged adults (40 to 59-years-old) than younger adults (20 to 39-year-olds) or older adults (60-years-old and over).

3. There was no real difference in obesity rates between men and women — everyone is getting fatter.

You can see the breakdown of obesity rates by age and gender in the chart below:

5. Obesity rates are not getting any better.

The CDC found there was no decrease in obesity rate from the 2009-2010 survey to the 2011-2012 survey.

The chart below shows that rates have been steadily getting worse since the 1980s:
