Duke study uncovers new information about obesity
by Mike Adams, the Health Ranger, NaturalNews Editor
Dr. Deborah Muoio at Duke University’s Sarah W. Stedman Nutrition and Metabolism Center discovered that obese people have three times as much SCD1, a fat-building enzyme in their muscle cells, as lean people do.
Severely obese people have three times as much of a fat-building enzyme called SCD1 in their muscle cells than lean people, scientists report.
That could be one reason why it's often hard to permanently lose weight through diet alone.
"While these findings may be somewhat discouraging news for those wishing to reverse obesity through dietary interventions, they also highlight the importance of exercise," says researcher Deborah Muoio, PhD, in a news release.
Exercise is known to produce big changes in muscle metabolism, explains Muoio.
She works at Duke University's Sarah W. Stedman Nutrition and Metabolism Center.
The researchers studied muscle cells from lean and obese women.
The obese patients were matched to lean patients of the same age and race.
The lean women had a BMI (body mass index) of 25 or less.
The obese women in the study had a BMI of 35 or more.
According to CDC provides guidelines for BMI,18.5 to 24.9 is normal, 25.0 to 29.9 is overweight, and 30 or more is considered obese.
