Is it possible to be both fit and fat?

On this morning's show Ed and Rachel were talking about how new research suggests that people can be physically healthy and fit, even if they are considered obese. 

Researchers explained that the key is being "metabolically fit" meaning no high blood pressure, cholesterol or raised blood sugar, and exercising.

Through looking at data of over 43,000 US people researchers found that being overweight per se did not pose a big health risk. It was concluded that those obese people that were metabolically healthy, who did not suffer from conditions such as diabetes, high cholesterol or high blood pressure, were generally fitter and exercised more than the other obese people.

The research highlights once again the important role of physical fitness as a health marker.
