Americans are fat.

The National Institutes of Health puts it bluntly.

About 65-percent of U.S. adults are overweight or obese.

The newest over-the-counter diet drug shows up in stores Friday.

It’s called Alli.

Channel 6 News talked to some people who do not expect it to be the miracle pill.

At the Curves fitness facility at 42nd and Center in Omaha, you'll find women who all want to look and feel their best.

"It does help control my weight," says Deb Litt.

"I know I won't have my 20-year-old body anymore but at least I know I can stay healthy."

These women say they don't mind sweating a little bit to reach their goals.

"I have tried over-the-counter medications before and I think there's too many adverse reactions," says Litt.

Now she has this to consider.

Alli claims it can help people lose 50 percent more weight than dieting alone.

You don't need a prescription.

It will sell on the shelf next to other weight loss aides.

Dr. Vidhu Bansal of GlaxoSmithkline says “It works locally in the G.I. Tract to inhabit 25 percent of the fat you're eating.

The maker of the drug, GlaxoSmithKline. claims it is revolutionary.

But it does come with undesirable side effects.

The Mayo Clinic reports gas, oily anal discharge, and loose stools, especially if someone tries to eat too much fat.

The women at Curves say “No, Thanks.”

The new ally for weight loss is not for them.

They measure their health not on their weight , but on the inches they lose with their workouts.

“Just stay in a healthy condition and you won't have a problem with weight. If you do have a problem with weight start cutting back, eating moderately,” says Litt.

Alli is actually a reduced-strength version of the prescription drug, Xenical.

It costs about $2a day.

For it to work effectively you need to exercise and maintain a healthy diet.

So you can't be a couch potato.
