A Mastering Diabetes testimonial says Kay’s A1c fell after she adopted the programme’s whole-food, plant-based approach, though her account is not independent clinical evidence.
Kay’s experience with type 2 diabetes began with a discovery she did not take seriously enough at first. Her elevated blood glucose was picked up during preparation for an unrelated medical procedure, and although her doctors monitored her numbers and later prescribed metformin, the improvement she needed did not come. According to Mastering Diabetes, she was still eating many of the foods she enjoyed, including chocolate and fizzy drinks, and she was not checking her glucose consistently. When her readings climbed to 8.5 mmol/L and then 8.7 mmol/L within days, she began to worry more seriously about what the future might hold.
That concern became more personal after someone close to her late husband lost a leg to diabetes-related complications, a reminder of how severe the disease can become when control slips away. Mastering Diabetes says Kay had already been exercising regularly and had tried to cut back on sugar, but she still felt stuck. The programme’s case material describes her as searching for a more structured approach, one that would give her clearer guidance than general advice about eating less bread or getting more exercise.
What she found, according to the company, was a low-fat, whole-food, plant-based framework built around simple food categories and coaching support. Mastering Diabetes says the approach helped her understand which foods to prioritise and how to build meals without relying on guesswork. The programme’s wider success stories and case studies make similar claims, describing improvements in insulin sensitivity, lower A1c readings, weight loss and reduced dependence on diabetes medicines among participants. In Kay’s case, the company says she was also able to join from Barbados, which mattered because she was initially unsure whether participation was limited to the United States.
The changes, Kay says in the account published by Mastering Diabetes, were not only visible on laboratory results. She reports that her A1c fell from 7.9% to 5.7%, and that her most recent reading was 5.5%. The company also says her glucose levels have often been in the 5 mmol/L range, with some in the 6 mmol/L range, and that her doctor has discussed reducing her medication. Just as striking for her, however, was the shift in how she felt day to day: less tired in the mornings, more able to manage stairs, and better able to get through the day without the persistent fatigue she had accepted as normal.
Mastering Diabetes presents Kay’s story as one example among many in its catalogue of testimonials and case studies, which are central to the company’s pitch. It says the programme is designed to help people with prediabetes, type 2 diabetes and other forms of blood sugar dysregulation lower A1c readings, reduce medication use and improve overall wellbeing. Kay’s account is more personal than scientific evidence, but it follows a familiar pattern in the company’s material: a diagnosis that did not improve with standard advice alone, a shift in diet and daily habits, and a sense of regained control. For Kay, that change was not just about numbers. It was about feeling better, making clearer choices and believing she could stay on course.
