No. Tom Hanks is not endorsing a diabetes cure. In August 2024, he warned that scammers were using his name, image and voice in fraudulent advertisements. One reported video reused television footage and made him appear to promote a “17-second grape trick” that supposedly reversed type 2 diabetes in less than three weeks. The endorsement was fabricated, and the medical promise is not credible.
What Tom Hanks actually said
Hanks has publicly said that he has type 2 diabetes and manages it with his board-certified doctor. His August 29, 2024 warning said he had no connection to the products, treatments or people featured in the online advertisements using his identity. The warning was reported by Yahoo Tech and PCMag.
That is fundamentally different from a genuine endorsement. A legitimate advertisement should be traceable to the celebrity’s verified accounts, the company’s identifiable official channels and legally required advertising disclosures. A clip circulating on social media is not proof that the person authorized it.
What the fake video claimed
According to PCMag’s report, the advertisement used footage of Hanks from Jimmy Kimmel Live! and altered the video and audio to make him appear to recommend a “17-second grape trick.” The sales pitch claimed the method could reverse type 2 diabetes in under three weeks.

The reported clip showed visible lip-synchronization problems. The story does not establish a confirmed manufacturer, ingredient list or single operator, so there is no responsible seller to identify from the available evidence. Do not follow links, phone numbers or checkout instructions shown in versions of the advertisement.
How the deception was made
The ad appears to combine several familiar manipulation techniques:
- Repurposed footage: A real interview or entertainment clip supplies a recognizable face and setting.
- Altered facial movement: The mouth and expressions are edited to match words Hanks did not say.
- Synthetic or manipulated audio: A generated or overdubbed voice is made to resemble his.
- Fake advertorial framing: The manipulated clip is placed beside a headline, testimonial or supposed news presentation.
- Trust transfer: The viewer is encouraged to trust the celebrity instead of demanding medical evidence.
“AI-powered scam” describes the reported presentation, not a forensic identification of a particular software model. A fraud can involve a fully synthetic video, a real video with generated speech, conventional dubbing or misleading editing. Lip-sync inconsistencies are a warning sign, but they are not by themselves laboratory authentication.
Why Hanks was a persuasive target
Scammers selected a person whose face and voice are instantly familiar and who has genuinely discussed living with type 2 diabetes. That real biographical detail makes a fabricated testimonial feel personal. The apparent endorsement can also discourage viewers from checking whether Hanks, a broadcaster or a company has published a matching announcement.

The tactic does not require the product to prove anything. It only has to make a viewer believe that a trusted person has already tried it.
There is no 17-second or three-week cure
The Federal Trade Commission’s consumer guidance says there is no cure for diabetes and warns that unproven products can interact with legitimate medicines or lead people to delay effective care: FTC consumer guidance. A promise of a universal cure in days or weeks is therefore a major health-scam warning sign.
Medical nuance matters. Some people with type 2 diabetes may achieve remission after substantial weight loss or other medically supervised interventions. Remission is not the same as a guaranteed, rapid or permanent cure. Type 1 diabetes requires ongoing management, and insulin remains essential for people whose bodies do not produce it. Treatment depends on diagnosis, glucose levels, medicines and other health conditions.
The advertisement provides no credible evidence that its claimed method works. Supplements are not automatically safe, effective or compatible with prescribed treatment. Federal regulators have previously sent warnings to companies making unsupported diabetes-treatment claims, including a 2021 FTC action involving 10 companies: FTC press release.

Red flags in celebrity health advertisements
- “Miracle,” “secret trick” or “breakthrough” language.
- A promise to cure or reverse diabetes in a few days or weeks.
- A celebrity testimonial that cannot be found on verified accounts or an official company site.
- A supposed television-news segment with no matching report on the named network’s website.
- Lips, blinking, lighting or facial edges that look unnatural.
- Voice cadence that sounds robotic, flat or slightly out of sync.
- Pressure to buy immediately or claims that supplies are almost gone.
- A “free” trial that requests card details, shipping fees or recurring billing.
- Testimonials used instead of published clinical evidence.
- Claims that doctors, drug companies or governments are suppressing the product.
- No clear company name, physical address, refund policy or responsible medical professional.
The FTC recommends searching the celebrity’s name, company and product together with words such as “scam” or “fake,” resisting pressure to act and asking a healthcare professional before using a supplement. See its alert on doctored celebrity endorsements: FTC consumer alert.
What to do if you saw or bought the ad
- Stop at the advertisement. Do not click its purchase link or enter payment, identity or medical information.
- Keep prescribed care unchanged. Do not stop insulin or another medicine because of a social-media claim.
- Verify independently. Check the celebrity’s verified accounts, the company’s official website and whether the alleged news segment actually aired.
- Ask a clinician or pharmacist. Have them review any product and its ingredients before use.
- Preserve evidence. Save screenshots, the account name, URL, date and any receipts. Obscure purchase links, QR codes and phone numbers before sharing screenshots publicly.
- Report it. Use the platform’s ad-reporting tools and submit suspected fraud to the FTC.
- Act quickly after payment. Contact your card issuer, bank, payment app or transfer service and request a reversal or fraud review. Watch for recurring charges.
- Get medical help when needed. If you stopped treatment, took an unknown substance or have serious symptoms, contact your healthcare professional or emergency services.
Why this scam can cause more than financial loss
An unverified product may lead someone to delay a diagnosis, stop effective medicine, combine an unknown supplement with prescriptions or experience dangerous glucose changes. “Free” trials and low-cost offers can also become automatic subscriptions, upsells or attempts to collect payment and identity data. These are common risks in this type of fraud, not proof of a particular seller’s billing practices.
How to verify a real endorsement
- Find the claim on the celebrity’s verified account or an official representative’s site.
- Look for the company’s legal identity, contact address, refund terms and advertising disclosures.
- Search the celebrity, product and “scam” or “fake” together.
- Check whether the medical claim is supported by credible clinical evidence rather than testimonials.
- Discuss the product with a qualified clinician before taking it.
