Thin people may be fat inside, some doctors say - USATODAY.com

Just because someone is lean doesn't make them immune to diabetes or other risk factors for heart disease," said Dr. Louis Teichholz, chief of cardiology at Hackensack University Medical Center in New Jersey, who was not involved in Bell's research.

Even people with normal Body Mass Index scores — a standard obesity measure that divides your weight by the square of your height — can have surprising levels of fat deposits inside.

Of the women scanned by Bell and his colleagues, as many as 45% of those with normal BMI scores (20 to 25) actually had excessive levels of internal fat. Among men, the percentage was nearly 60%.

Relating the news to what Bell calls "TOFIs" — people who are "thin outside, fat inside" — is rarely uneventful. "The thinner people are, the bigger the surprise," he said, adding the researchers even found TOFIs among people who are professional models.

According to Bell, people who are fat on the inside are essentially on the threshold of being obese. They eat too many fatty, sugary foods — and exercise too little to work it off — but they are not eating enough to actually be fat. Scientists believe we naturally accumulate fat around the belly first, but at some point, the body may start storing it elsewhere.
