Kyle Sandilands recently lost approximately 18 kilograms, or nearly 40 pounds, without weight loss medication. He is now being paid to promote a men’s health platform that offers medical weight loss programs, including prescription treatment for eligible patients.
The 55-year-old Australian broadcaster is fronting a national radio campaign for Mosh. According to the Herald Sun, Sandilands is not a Mosh customer and did not use weight loss medication to achieve his recent 18 kilogram loss.
Several Australian doctors have questioned the partnership, focusing on the influence of celebrity endorsements and whether remote consultations can identify every patient who should not receive prescription treatment. Sandilands’ manager says the advertisement is a brand endorsement rather than a testimonial about his own medical care.
Mosh has defended its clinical process, saying patients are screened by qualified practitioners and that some applicants are rejected or sent for face to face assessment. The company says Sandilands was chosen because he has spoken publicly for years about his own difficulties with weight.
Mosh Did Not Cause Sandilands’ Recent Weight Loss
Sandilands has discussed his weight publicly for years. In 2025, after saying he had reached 138 kilograms, or nearly 40 pounds, he began tracking his efforts through a radio segment he called the “Big Fatso Club.” A KIIS 106.5 video captured one of the weekly weigh ins.
His more recent loss came before the Mosh advertising deal. In the new radio spot, Sandilands acknowledges that losing weight has been difficult for him and says Mosh has programs that may help people like him make their results last.
He does not say that Mosh produced his own weight loss or identify a particular prescription medicine. His manager, Bruno Bouchet, told the Herald Sun that Sandilands’ involvement should be understood as an endorsement of the company rather than a personal treatment testimonial.
Doctors Questioned the Celebrity Endorsement and Remote Care
Bariatric surgeons Dr. Nick Williams and Dr. Alex Craven were among the doctors who raised concerns about the campaign. Their objections centered on the influence celebrities can have over health decisions and the limits of assessing some patients without an in person examination.
The Royal Australian College of General Practitioners takes a broader position on telehealth only services. Its current guidance says telehealth can play a legitimate role in care but should not replace routine in person medicine, and prescribing should involve a real time consultation rather than a questionnaire alone.
Mosh says its prescription process begins with an online assessment followed by a consultation with a health practitioner, rather than automatic approval for medication.
Mosh Says Some Applicants Are Referred for In Person Care
Mosh medical director Dr. Tushar Yadav defended the company’s model, saying screening includes medical history, current medications, mental health, eating disorder history, lifestyle factors and treatment goals.
Mosh’s official weight loss site says its programs provide access to Australian practitioners and can include medical treatment, ongoing practitioner support, nutrition guidance and dietitian services. Patients interested in prescription treatment are connected with an independent doctor or nurse practitioner who determines whether prescribing is appropriate.
Yadav said about one third of people approaching Mosh are rejected or referred for an in person consultation. He also acknowledged that telehealth is suitable for some patients rather than everyone.
Sandilands remains an endorser rather than a patient in the campaign. Neither he nor Mosh has claimed that the company’s medical program produced the 18 kilogram weight loss that preceded the advertising deal.
