The new capsule is swallowed like a pill, but it's not a medicine, it's a gel to fill people up. Max Gomez of CBS2.
Recent figures show that about two thirds of Americans are overweight or obese.
Over the years, there have been a number of weight loss drugs, and though most work to some extent, they, like all other medications, also have side effects.
Like so many people, Suzie Soto has been doing a weight loss seesaw for years.
"I tried pills," she said. "A variety of diets, shakes, everything else and just nothing worked."
Now there is a new option for millions like Soto who are trying to lose weight, called plenity capsules.
Dr. Louis Aronne, a renowned obesity researcher at New York's Presyterian Weill Cornell, has done some clinical studies on Plenity and says that they are actually considered a powerful new weight loss technology.
"This opens up a vast new patient population to a whole new medical treatment," he said.
The FDA has approved the plenary for anyone with a body mass index (BMI) of 25-40. You only need to be 1
After swallowing the capsules, they absorb 100 times their weight in water and form a soft gel in the stomach.
Due to the unique molecular structure of the gel, it binds to and integrates with the food, slowing its absorption.
This gel-food complex claims about a quarter of the average stomach. Since the gel is not metabolized or absorbed, it does not have more side effects than placebo, but it has a double weight loss effect.
"It makes you feel full faster, but slows down the absorption of calories, a dampening effect on the appetite that goes beyond the filling effect," said Aronne.
In clinical trials, volunteers lost an average of 6.5 percent of their body weight, but most lost as much as 10 percent, including diabetics and pre-diabetics who were most at risk
Plenity will not be available until the end of the year. The costs and the insurance cover were not determined.
