But what exactly is Qnexa? And how will it effect the millions of obese men and women living in America? Well, we're glad you asked. Here's what you need to know.

Qnexa is a weight-loss pill that comes from Vivus Inc. It's the first such drug to be approved by the FDA in 13 years. Meaning: This is a huge deal. But what exactly does it do?

According to the LA Times, it merges the effects of two medications you can already get your hands on: topiramate and phentermine. One is an anti-seizure medicine and the other an appetite suppressant.

According to the actual company that distributes it, Qnexa helps you lose weight by suppressing your appetite, while increasing one's sensation of "satiety." In other words, it makes you think you're full, which subsequently helps you stop eating so much.
