Quick Answer
Every advertisement or product claiming to be a "Shark Tank weight loss" supplement is a scam. None of the investors from Shark Tank, often called the sharks, has ever endorsed a weight-loss supplement on the show or in any paid advertisement. If you see a keto gummy, diet pill, or fat-burner promoted with a Shark Tank logo or a shark’s photo, it is a fake endorsement. No legitimate Shark Tank–backed weight-loss supplement exists.
Main Explanation
How the Scam Works
Scammers create fake ads that include the logos of major publishers, false news articles, and fabricated testimonials. They often claim a product was a “hit on Shark Tank” or that all five sharks invested. In reality, the show’s producers and the sharks have repeatedly stated that these endorsements are fiction. One common variant is a fake article titled “Weight loss pill that naturally burns fat gets biggest deal in Shark Tank history”, a completely fabricated story designed to redirect readers to a product sales page.
The FTC and AARP Warnings
- The Federal Trade Commission (FTC) warns that scammers use the names and images of Shark Tank investors to sell weight-loss products.
- AARP’s fraud team reports that “none of the Shark Tank investors, or sharks, as they're known, has ever endorsed a weight-loss supplement, on-air or in an ad”.
- Fact-checking organizations, including USA Today, have confirmed that such endorsements are false.
What About Products on Amazon?
Searching for “shark tank keto” on Amazon returns products that use the phrase in their listing titles, but this is keyword stuffing, not an official connection. No legitimate Shark Tank–backed weight-loss supplement exists.
Decision Framework: How to Spot a Fake Shark Tank Weight-Loss Ad
Use these ordered steps, based on verified sources, to decide whether a “Shark Tank” weight-loss product is legitimate.
Step 1: Check the Official Shark Tank Product List
Go to ABC’s official list of every product that has ever appeared on the show. If the weight-loss supplement is not on that list, it never appeared on Shark Tank and no shark endorsed it. The list is updated periodically and includes no weight-loss supplements.
Step 2: Look for Fake News Articles
Scammers often create fake news sites that mimic major publishers. Look for grammatical errors, missing bylines, or a URL that doesn’t match the publisher’s official domain. Legitimate news articles about Shark Tank products are rare; weight-loss supplements are almost always fabricated.
Step 3: Verify Endorsements on Official Social Media
Go to the verified social media accounts of the sharks (e.g., Mark Cuban, Lori Greiner, Kevin O’Leary). If they actually endorsed a product, it would be posted on their official profiles. No shark has ever posted about a weight-loss supplement.
Step 4: Recognize Common Red Flags
- “Limited time offer” or “one-time payment” pressure tactics.
- Logos of AARP, CNN, or other trusted brands used without permission.
- A price that starts at $39.99 and then increases dramatically after you enter payment info.
- Claims like “natural” or “slows fat production” without clinical evidence.
Step 5: Report the Scam
If you encounter a fake Shark Tank weight-loss ad, report it to the FTC at ReportFraud.ftc.gov. You can also alert AARP’s fraud watch network.
Practical Takeaways
- Never click on links in social media ads claiming Shark Tank endorsement; they are almost certainly phishing or sales pages for unregulated supplements.
- If you’ve already purchased, contact your credit card company to dispute the charge and monitor your bank statements for unauthorized transactions.
