Kyle Sandilands lost about 18 kg (nearly 40 lb) without prescription drugs and is now the paid radio endorser for Mosh, a medical weight-loss platform. Several Australian doctors have raised concerns that celebrity endorsements may unduly influence public health decisions and that telehealth assessments could miss patients unsuited to prescription therapy. Mosh says it uses qualified practitioners, conducts live consultations after online screening, and refers roughly one-third of applicants for in-person review. Sandilands and his manager stress the ad is a brand endorsement, not a claim that Mosh produced his weight loss.
Kyle Sandilands Drops 18kg Without Drugs — Doctors Question His Paid Mosh Endorsement

Kyle Sandilands, the 55-year-old Australian radio presenter, recently lost about 18 kilograms (roughly 40 pounds) without using prescription weight-loss medication and is now the paid national radio face of Mosh, a men’s health platform that offers medical weight-loss programs—including prescription treatments for eligible patients.
What Happened
Sandilands fronts a new national radio campaign for Mosh but, according to the Herald Sun, he is not a Mosh client and did not use prescription drugs to achieve his recent 18 kg loss. His manager, Bruno Bouchet, says the spot is a brand endorsement rather than a personal medical testimonial.
Medical Community Raises Concerns
Several Australian clinicians have questioned the partnership. Bariatric surgeons Dr. Nick Williams and Dr. Alex Craven warned that celebrity endorsements can strongly influence public health decisions and expressed concern that some patients who should not receive prescription therapy might be missed in remote assessments.
The Royal Australian College of General Practitioners (RACGP) takes a cautious stance on telehealth-only services, noting that while telehealth can be a legitimate part of care, it should not replace routine in-person medicine. The college advises that prescribing should involve a real-time clinical consultation rather than relying solely on questionnaires.
Mosh's Response
Mosh says its process begins with an online assessment followed by a live consultation with a qualified health practitioner, and that medication is not automatically approved. Dr. Tushar Yadav, Mosh's medical director, told reporters that screenings include medical history, current medications, mental health and eating-disorder history, lifestyle factors and treatment goals. He added that roughly one-third of applicants are either rejected or referred for an in-person assessment.
Mosh also says it chose Sandilands for the campaign because he has publicly discussed long-standing struggles with his weight and the challenges of sustaining weight loss.
Context And Clarifications
Sandilands has publicly tracked his weight for years. In 2025 he said he had reached about 138 kilograms (approximately 304 pounds) and later documented efforts to lose weight on a radio segment he called the "Big Fatso Club." KIIS 106.5 recorded some of those weekly weigh-ins. His most recent 18 kg loss occurred before the Mosh advertising deal.
In the new radio spot, Sandilands acknowledges how difficult weight loss has been for him and suggests Mosh's programs may help people maintain results. Neither he nor Mosh claim that the company's medical program produced his personal weight loss, and the advertisement does not identify any specific prescription medication.
Bottom line: The campaign highlights tensions between celebrity endorsements for medical services and the limits of telehealth prescribing. Mosh defends its clinical safeguards, while some doctors urge caution and greater reliance on in-person assessments where appropriate.
