Could it be the magic weight loss pill everyone has hoped for?
In a new study, the experimental drug, rimonabant, was given to 3,000 people who also adopted a program of diet and exercise.
After one year, those on the highest dose of rimonabant lost an average of 13 pounds more, and had an easier time keeping it off.
Researchers say the drug curbs appetite by affecting the way the brain desires food.
And it may even block other cravings and addictions, like smoking.
