We all race for a reason - this is mine

There are moments in all of our lives when we need to stop what we're doing, take a second, look around, and soak it all in.

1 in 3 is obese - even the homeless

Obesity is a widespread epidemic, even among the homeless.

While the popularized image of a homeless individual is one of skin and bones, a new study shows the reality is not so. One in three (32.3%) homeless individuals in the United States is obese, highlighting a hunger-obesity paradox.

The paradox is that hunger and obesity can exist in the same person. And although a person may be overweight or obese, he or she can lack proper nutrition.

Nutrition is a daily challenge for homeless people, as the foods they manage to get are often full of preservatives and high in sodium, fats and sugars.  They may not have access to healthier options like fresh fruits and vegetables.

Triathlete: Running vs. triathlon running
