Apparently you can be thin on the outside, but fat on the inside—interesting. Maria Cheng of the Associated Press has more:I’ve never read anything like this before.
"Being thin doesn't automatically mean you're not fat," said Dr. Jimmy Bell, a professor of molecular imaging at Imperial College, London. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create "fat maps" showing where people store fat.
According to the data, people who maintain their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are otherwise slim. "The whole concept of being fat needs to be redefined," said Bell, whose research is funded by Britain's Medical Research Council.
Without a clear warning signal — like a rounder middle — doctors worry that thin people may be lulled into falsely assuming that because they're not overweight, they're healthy.
