Snooki's weight loss has been a topic of conversation ever since the pint-sized reality star began tweeting photos of her noticeably slimmer-self in September. Now, Snooki is flaunting her 98-pound figure for the whole world to see in a new Zantrex-3 commercial.

Snooki tweeted a link to a sneak-peek clip of her new Zantrex commercial, writing OMG tweedos!! Check out a SNEAK PEAK of my new video, so much fun dancing around and love the big hair RAWR.

In the commercial, the Jersey Shore star shimmies and shakes in a strapless mini dress, showing off her toned legs and thin arms. Snooki, who has been tweeting about her weight loss ever since she began shedding the pounds, has made the public well-aware of the fact that Zantrex is to thank for her new figure.

The Zantrex-3 pill contains yerba mate, green tea, guarana and caffeine. The reality diva has said that it gives her energy to work-out at the gym. However, many health specialists have criticized Snooki for promoting a quick fix.

Dr Keith Ayoob, associate professor at Albert Einstein College of Medicine told ABC: This is outrageous. It's a perfect example of bad endorsement. It's a quick fix, potentially a dangerous one, and celebs may have a high profile, but they're often not very credible sources.

Dr. Carl Lavie, Director of the Stress Testing Lab at John Ochsner Heart and Vascular Institute added that the pill's caffeine can be bad for the heart. He said: For young, healthy people, a small-to-modest dose of caffeine should not be very risky, but even in young people, bur more so in older with underlying heart disease, high doses of caffeine can cause a number of bad heart rhythm.

Zantrex-3 is sold over-the-counter and is classified as a supplement, therefore it is not regulated by the Food and Drug Administration.

But Snooki is proud to say that she took Zantrex-3 and it worked for her.

The pint-sized star made headlines last week when she tweeted fans a photo of herself without makeup. Snook, who is known for wearing layers of bronzer, false eyelashes and gobs of lip gloss - photographed herself without any make-up on and tweeted it to fans. The 24-year-old posted, No make up day :) and IDC :) along with a photo of her fresh face.

Fans followed-up with a slew of praise and adoration, telling Snooki how great she looked. Snooki is 10 times more beautiful without makeup posted one Twitter user. SNOOKI? wow...She looks way better without makeup, wrote another.

Snooki responded Can I just say how AMAZING my fans/supporters are! You guys really know how to put a smile on my face! Love You all beyond words....

Snooki has never been seen au natural before. It is a stunning new look for the reality diva.
