(HealthDay News) -- A fatty acid found in olive oil and other heart-healthy monounsaturated fats wards off hunger pangs, a new study suggests.

The findings might one day lead to the development of new drugs to limit, or even enhance, appetite, the researchers said.

Daniele Piomelli, a professor of pharmacology at the University of California, Irvine, and his colleagues infused the fat -- called oleic acid -- into the intestines of laboratory rodents and found that it was converted into a fat messenger called oleoylethanolamide (OEA).

"I don't smoke." "I exercise regularly." "Yeah, I floss." If you've ever looked into your doctor's eyes and told her a half-truth — or even an outright falsehood — join the club.

Fitness myths get started because we all react to exercise and diet a little different than anyone else.

(HealthDay News) -- Adding occupational therapy to a structured exercise program increases physical activity for most people who have hip and knee osteoarthritis, say researchers.

Osteoarthritis is a degenerative disease that leads to the breakdown of the cartilage in joints. In people with osteoarthritis, exercise helps maintain good joint health, manage symptoms and prevent functional decline.

But studies have shown that the benefits of a structured exercise program are short-lived. The beneficial effects usually fade soon after participation in the program ends.

I've been lucky enough to go abroad on just a few occasions, but what they say is true: People in most other countries just don't weigh as much as we do.

My mother is trying to find a beginning yoga exercise tape (with good music!), and I don't even know where to start looking for her.

I've thought of amazon.com, with the customer reviews, but are there any credible "industry standards" for exercise tapes. (I just remember the Denise Richard videos...was that her name?--that were actually harmful). How do I know if an exercise tape includes good, quality exercises? Is there a website or over-seeing organization that I should look into?
