If you've been paying any attention to the news lately, you've likely heard a lot about obesity. But what is obesity and how does it differ from plain old overweight? And why is a little body fat so harmful anyway?
Your weight "status" is roughly determined by your body mass index or BMI, which is a number that compares your weight to your height. A healthy BMI ranges between 18.5 and 24.9, while anything under 18.5 is considered underweight.

If it's over 30.0, you've joined the almost 25% of Canadians that are considered obese.
