As we shed the bulky sweaters and heavy coats for warmer weather, the extra pounds we put on over the winter become more noticeable.

Some of us will be looking at ways to slim down so we can wear sundresses and sleeveless shirts.

One group is warning against using the over-the-counter drug Alli to aid in our weight loss efforts.

Public Citizen wrote a petition to the Food and Drug Administration earlier this month saying Alli, and its prescription form Xenical, should be removed from shelves because it can damage the liver, cause kidney stones and result in acute pancreatitis.

The group said the risks of the drugs outweigh the benefits. They also note that the benefits are questionable because the weight loss isn't much more than if people would just diet or exercise.

“These drugs have the potential to cause significant damage to multiple critical organs, yet they provide meager benefits in reducing weight loss in obese and overweight patients," said Dr. Sidney Wolfe, director of Public Citizen’s Health Research Group.

Any of you have experiences with the drugs? Were you able to lose weight?
