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.

Frequently asked

Can you improve diabetes without medication using a plant-based diet?

Yes, Dave Fabry was drawn to Mastering Diabetes because of the common-sense idea that you can improve or reverse diabetes using a plant-based diet. He successfully lowered his A1c from 7.1 to 5.9 strictly through the diet he used to control insulin resistance.

Will I lose exercise stamina on a plant-based diabetes program?

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.

Full transcript

My name is, uh, Dave Fabry. I'm from Pennsylvania, and I have type 2 diabetes. Okay. Well, I've been struggling with this for fifteen years. I was on a designer drug called Zixlambi for probably twelve years. Um, my numbers started going way off kilter, and I actually f- uh, went to my, um, ophthalmologist 'cause I have eye problems, and he said that I need to get my diabetes under control. And, uh, I went to, to see an endocrinologist. That was in June of twenty twenty-five, and she put me on, uh, Mounjaro. Uh, and I was on that for a while until about December. I, I got blood tested again, and my numbers were going the wrong way. So I said, "I have to do something." And I was looking around, and that's how I find- found, uh, Mastering Diabetes in January of twenty twenty-six. I don't hear you anymore. Okay. All right. Okay. My name is, uh, Dave Fabry. Well, I've been, uh, going through this for about fifteen years. I, uh, have macular degeneration. I go to an ophthalmologist every six months, and he s- suggested in beginning of twenty twenty-five that I go see an endocrinologist for my type 2 diabetes. And I did that, and the d-- doctor had put me on some, uh, low levels Mounjaro and Jardiance, and I couldn't stand the Jardiance. And that was around April of twenty twenty-five, and by the end of twenty twenty-five, my numbers kept going the wrong way. So I was looking for some alternative solution to, uh, my diabetic condition, and that's when I found Mastering Diabetes in the end of, uh, twenty twenty-five. Before starting Mastering Diabetes, my, uh, A1C was seven point one. That was in January of 2026. Uh, my weight was, uh, one ninety-five at that time. Um, and the, um, medications that I was on, I was on a low... the low dose of Mounjaro at the time, and that was all, all. Uh, I had been as high as I believe seven point eight in probably around April of 2025, uh, at that time, before I went to see the endocrinologist. Um, what drew me to Mastering Diabetes was, um, on, on, on the common sense that you can improve or reverse diabetes with- without medication and just using a plant-based, uh, diet. And I was convinced that that was very possible. I mi- I missed what you said. Um, not really. Um, th- th- there was a book written by, uh, a Doctor Barnard on probably 10, 15 years ago that I had read, and he, he, he, he had the same idea of a plant-based diet to reverse, uh, insulin resistance. So I knew, uh... Un- unfortunately, I didn't follow that. I probably wouldn't have been in the situation that I was in, but, uh... And that's how I knew that the Mastering Diabetes would work. Uh, my, my current weight is around, uh, one seventy-five. My AN... A1C in January was seven point one, and as of, uh, beginning of June of this year, it was at five point nine. So I was really happy with results based on strictly the diet that I was, uh, using to control the, the insulin resistance. I'm currently on, um, a point five or five, uh, dose of Mounjaro, and I do that every 14 days, and I'm looking to get off of that currently. And that's all that I... Uh, energy level has gone up, uh, quite a bit. I'm not tired. I don't have any sugar cravings. Um, I feel pretty good. I've always was an exerciser, so that was a... I was able to maintain that throughou- through, you know, doing this. I thought I'd may lose some stamina or anything like that, but that has not occurred. Um, the investment is certainly worth it. It, it taught me a lot. Learned a lot about myself. I need to, uh, you know... I didn't realize at the time that diabetes takes, uh, a long time to get, and it takes a long time to fix at the same time. That you can't expect miracles to happen overnight. Takes time. You gotta keep the discipline, keep the faith, and it'll work. Well, reversing insulin, it changes your health dramatically, uh, whether you know it or not. Of, of all the, the diseases that it causes and the heartache that it causes, I, I've, um, fortunately didn't have that happen to me. I don't know why, but, um, outside of... I didn't get a lot of skin tags or, um, the obvious telltale signs of insulin resistance. I didn't have them, and maybe that's why it didn't bother me so bad. But, um, people have to realize, you know, you only have, uh, at any one time, supposed to have a cube of sugar in your blood. And if you're gonna go eat a donut, you know, that, that multiplies that by 10 in, in one swell soup. In a matter of minutes, if you've eaten that and you have to realize you can't do that. Uh, before Mastering Diabetes, my A1C went from 7.1 to 5.9 in a matter of six months. Okay. Before di- uh, Mastering Diabetes, my A1C went from 7.1 to 5.9. Uh, before Mastering Diabetes, my A1C went from 7.1 to 5.9. Well, I really haven't stopped any medica- I'm trying to get off it. I have a note into my doctor right now to see if, uh, I'm on a low dose of Mounjaro, but it's giving me p- lots of issues, so I'm trying to just get off of that. Yes. Yes.
