The interview
Can you introduce yourself and describe your history with diabetes?
My name is Dave Fabry. I'm from Pennsylvania, and I have type 2 diabetes. I've been struggling with this for fifteen years. I was on a designer drug called Zixlambi for probably twelve years. My numbers started going way off kilter, and I actually went to my ophthalmologist 'cause I have eye problems, and he said that I need to get my diabetes under control.
What led you to seek an alternative solution like Mastering Diabetes?
I went to see an endocrinologist in June of 2025, and she put me on Mounjaro and Jardiance. I couldn't stand the Jardiance. By the end of 2025, my numbers kept going the wrong way. I was looking for some alternative solution to my diabetic condition, and that's when I found Mastering Diabetes in January of 2026.
What were your health markers before starting the program?
Before starting Mastering Diabetes, my A1C was 7.1 in January of 2026. My weight was 195 at that time. I had been as high as 7.8 in April of 2025 before I went to see the endocrinologist. I was on a low dose of Mounjaro at the time.
What specifically drew you to the Mastering Diabetes approach?
What drew me was the common sense that you can improve or reverse diabetes without medication and just using a plant-based diet. I was convinced that that was very possible. I had read a book by a Doctor Barnard 10 or 15 years ago with the same idea, and that's how I knew that Mastering Diabetes would work.
What results have you seen since starting the program?
My current weight is around 175. My A1C in January was 7.1, and as of the beginning of June of this year, it was at 5.9. I was really happy with results based on strictly the diet that I was using to control the insulin resistance. My energy level has gone up quite a bit. I'm not tired. I don't have any sugar cravings. I feel pretty good.
How has the program affected your medication use and physical activity?
I'm currently on a .5 dose of Mounjaro every 14 days, and I'm looking to get off of that currently. I've always was an exerciser. I thought I'd may lose some stamina, but that has not occurred.
What is your advice to others considering this investment?
The investment is certainly worth it. It taught me a lot. I didn't realize at the time that diabetes takes a long time to get, and it takes a long time to fix at the same time. You gotta keep the discipline, keep the faith, and it'll work.

Dave Fabry, a regular exerciser, initially thought he might lose stamina or energy while transitioning his diet. However, he reported that his energy levels actually went up quite a bit and no loss of stamina occurred.
How long does it take to see results with Mastering Diabetes?
Dave Fabry notes that diabetes takes a long time to develop and a long time to fix, advising others that you can't expect miracles overnight. In his case, he achieved a significant A1c reduction and weight loss over a six-month period.
