Belinda’s husband, Dr. Gary Fettke, was targeted by the processed food industry for his public opinion on the perils of excessive sugar consumption and for showing the potential to put patients with Type 2 diabetes into remission. This caused him to him to be ‘silenced’ by the Australian Health Practitioner Regulation Agency.

To clear Gary’s name Belinda did a lot of work looking into the organizations linked to the accusations that led to the silencing. Belinda’s information withstood Australian legal process, and the story has a happy ending; 2018 saw a clearance of those charges with a full apology from the Medical Board.

The story of Dr. Gary Fettke shows the importance of protecting the principles of preventive medicine and healthy eating. The fight for the right to speak openly about the harm of sugar emphasizes that systemic support and verified information are critical to preserving people's health.
