High-Fat Diets OK for Obese Individuals?

Jupiterimages/Thinkstock(BALTIMORE) -- The Zone Diet, the Atkins Diet, the Dukan Diet, low-carb, low-fat, raw food, no food…it's quite amazing what people will try to do in order to lose weight. And many diets are not safe. In fact, some are outright dangerous.  

Doctors at Johns Hopkins University studied whether a low-carb, high-fat diet posed a serious health risk to obese individuals, since high-fat foods may increase risk of clogged arteries.  They divided 46 overweight or obese participants into two groups:  one group was on a low-carb/higher fat diet while the other on a low-fat/higher carb diet.  Both groups exercised equally.  Once the participants lost 10 pounds, their blood vessels were checked to see if any signs of stiffness of the arteries could be seen.  

The authors found that there were no differences in vascular health between the groups, so it seems that the low-carb/higher fat diet does not pose a health risk to obese people trying to lose weight.  Furthermore, it worked faster:  the group on the low-carb/higher fat diet reached 10 pounds of weight loss sooner than the low-fat/higher carb diet group, at 45 compared to 70 days respectively.
 
But even the authors acknowledge that their study does not provide information about long-term health effects of a low-carb/higher fat diet since they only tested the participants at most 2.5 months after starting the diet.  An obese individual likely needs to lose more than just 10 pounds -- so how would their arteries look and function after 10 months on the diet or longer?
