A 78-year-old man with long-standing type 2 diabetes has significantly improved his condition after adopting a low-fat, whole-food, plant-based diet, shedding nearly 60 pounds and reducing medications, highlighting a potential shift in diabetes care approaches.
At 78, Mike says he has regained control of a condition that had been drifting in the wrong direction for years. The retiree, who has lived with type 2 diabetes for nearly three decades, now has an A1c of 6.1% after seeing it rise into the 9% to 11% range, according to a Mastering Diabetes case study published on the organisation’s website. He has also trimmed his fasting blood glucose from readings of roughly 200 to 250 mg/dL to around 100 to 110 mg/dL, and he says he has shed almost 60 pounds.
For much of his adult life, Mike was able to keep active through gardening and outdoor work, but that changed when his wife developed kidney problems and required dialysis. According to the account on the Mastering Diabetes website, he spent about eight hours a day helping with her home treatment while continuing to work, and his own exercise routine largely disappeared. As his activity levels fell, his glucose readings worsened and his doctor began discussing insulin as a possible next step.
The turning point came after his wife died. One of his doctors, described on the site as being vegan herself, pointed him to Mastering Diabetes and its educational material. Mike started by watching the group’s videos, then later joined its coaching programme. Mastering Diabetes says its method centres on a low-fat, whole-food, plant-based diet intended to improve insulin sensitivity, a message that differs sharply from the standard advice many people with diabetes have long heard about cutting carbohydrates and eating more fat.
That change in approach required a major adjustment for Mike. He says he had to rethink foods he once considered harmless, including crackers made with almond flour that appeared sugar-free but contained enough fat to affect his glucose readings. With help from a coach, he learned to look beyond front-of-pack claims and check the full nutrition label, including serving size and total fat. He also found he could build meals around beans, rice and salad dressings that fit the plan while still eating more food overall.
Mastering Diabetes says Mike’s progress has been measurable across several markers. The organisation lists his weight falling from about 200 pounds to around 140 pounds, while his medication regimen has also changed. He is no longer taking losartan and did not need to move on to insulin. He still takes metformin, and he plans to speak with his doctor about whether the dose can be reduced further.
His story fits a broader pattern promoted by the organisation, which regularly publishes testimonials and case studies from people who say they have lowered A1c levels, reduced insulin use and lost weight after adopting a similar eating pattern. Those accounts are not a substitute for medical advice, and the results vary from person to person, but they illustrate the appeal of lifestyle-focused diabetes management for some patients who want to avoid escalating medication. For Mike, the lesson has been straightforward: after years of caregiving, he says the effort to change how he eats has been worth it.
