Diet and Exercise Keep the Invisible Fat Off Too

Some doctors now believe internal fat surrounding vital organs could be as dangerous as more obvious external fat.

What's more, people who maintain a slim appearance through diet alone, without exercise, are likely to have major deposits of internal fat. As one doctor put it, "Being thin doesn't automatically mean you're not fat."

Doctors are concerned that those without the clear warning signal of exterior fat may be falsely assuming that they are healthy. In fact, they still could be at risk for diabetes or heart disease.

Researchers who scanned some 800 male and female patients with MRI machines that plotted internal fat maps found that as many as 45 percent of women and 60 percent of men with normal BMI scores (20 to 25) had excessive levels of internal fat. Researchers even found "TOFIs" (people who are "thin outside, fat inside") who were professional models.
