The interview

Can you introduce yourself and describe your health background?

I'm Vivian Montet from Carencro, Louisiana, and I'm a Type 2 diabetic. I have basically been overweight all my life, but I never had diabetes until 2018 after I had a stroke. I went to the doctor every year for blood work and nothing showed up until then, when I was told I had high glucose levels and was pre-diabetic.

How did you discover Mastering Diabetes and what was your initial experience?

I stumbled upon Robby in a YouTube video around 2020. I decided to try it because other dieticians were telling me not to eat carbs. Within three months, my life changed. The first few weeks weren't as bad as I thought because I was already about 75% plant-based, though it felt overwhelming at the very beginning until I realized my 'why'.

What specific changes did you make to your diet and lifestyle?

I pretty much cleared out my refrigerator and my pantry and got rid of all the junk stuff, processed boxed food, and all that. I began meal prepping things like beans, lentils, and quinoa. I also realized I didn't need to be at the gym three times a day or spinning twice a day like I used to; this program is much more manageable for someone with a life and eight grandchildren.

What were the specific results regarding your A1c and weight?

From the beginning in 2018, my A1C was 7.1. By following the videos on my own, it dropped to 6.2. After really getting on the program, my doctor took an A1c in December that was 5.9, and recently an online check with Robby showed it was down to 5.4. I have also lost about 12 pounds, which is more than I ever lost even when exercising intensely.

How did your medical treatment change after starting the program?

I was taking Metformin twice a day, 500 milligrams. After a week of being strictly plant-based, I did blood work and my doctor asked what I was doing because my numbers dropped significantly. She told me to continue what I was doing and took me off of the Metformin. I went from that to an injection once a week, and I'm hoping to be taken off the injections soon.

What physical and mental improvements have you noticed?

After getting off the medication, I felt less inflammation. I feel 100% better and my mental clarity is definitely much better. I am very active, I have a garden, and nothing really stops me.

Frequently asked

Is the Mastering Diabetes program difficult to follow with a busy lifestyle?

Vivian found the program manageable even with eight grandchildren and a busy schedule. She noted that it was easier than her previous routine of going to the gym three times a day because the plant-based meal prep is accessible and quick.

Can I lower my A1c without face-to-face coaching?

Yes, Vivian initially lowered her A1c from 7.1 to 6.2 just by watching Mastering Diabetes YouTube videos and clearing her pantry. She later achieved a 5.4 A1c after engaging more deeply with the program's resources and online checks.

Will a plant-based diet help me reduce diabetes medications?

Vivian reported that her doctor took her off 500mg of Metformin twice daily after seeing the significant drop in her blood sugar numbers from eating grains, beans, and whole plant foods.

Full transcript

Hi. Vivian Montet. I'm from Carencro, Louisiana, and I'm a Type 2 diabetic. Okay, um, I basically have always pretty much been overweight all my life. Um, I never had diabetes until 2018. I had a stroke, and trying to figure out what caused the stroke, a lot of things started coming up, and I went to the doctor every year for blood work and nothing ever showed up. Um, I was told that I had high levels of glucose and that I was pre-diabetic and, uh, was referred to a dietician, and there's... Since 2018, I've been trying to figure out what's going on, and I came across Robby in a YouTube video that I stumbled upon, and I've been following him since 2020 probably. And I just decided 'cause this other form of, you know, dieticians telling you not to eat carbs and all that good stuff, you know the drill, um, I felt that this could help me, and within three months, like my life changed. Okay. Um, the first few weeks of Mastering Diabetes really wasn't as bad as I thought because I had already transitioned into eating plant-based foods. Not 100%, but about 75%. So it really wasn't that hard for me, but it was a change that... It felt very overwhelming at the beginning, but once I realized my why to having to do this, it, it was okay. Uh, it, it worked out. So from the beginning in 2018, my, uh, A1C was 7.1, and when I started following Robby is when I realized I could maybe work on getting these numbers down through watching all his Mastering Diabetes videos. Um, I started on my own, just... I pretty much cleared out my refrigerator and my pantry and got rid of all the junk stuff, that processed boxed food and all that, and, um, began meal prepping, you know, beans and lentils and, um, quinoa and all those good things for you. It jumped from like 7.1 to like 6.2 I guess in a couple of years. That's before I even had any coaching. And I couldn't find any, um, coaches or dieticians in Louisiana that were plant-based. So, uh, that was the struggle, and I wanted to have someone face to face that I could sit with and discuss, you know, my options and different ways of preparing foods and, you know, that kind of thing. Um, when I finally decided, I started in October or November of last year, like really looking at his videos, the Mastering Diabetes videos, and, um, I really started getting very... I'm not... I don't want to say anxious. You might have to edit this. Um, so my changes in my A1C, I noticed... Well, I didn't notice it 'cause I was not actually, um, checking my A1C, but I was checking my glucose daily. Um, I would say within a week and a half of really being on the program is when I noticed that my numbers were dropping. Since being on Mastering Diabetes, uh, my life has tremendously changed. Within three months, um, my last A1C, which was taken by my doctor, uh, in December of last year, was 5.9, and, uh, a couple of three weeks ago maybe, uh, Robby and I had a conference and he-- we did an online A1C check and it was down to 5.4. So that really validated that this program, Mastering Diabetes, works. My weight, I have lost maybe 12 pounds since, but I mean, that's a lot. That's more than I've ever lost besides going to the gym three times a day, spinning, you know, twice a day, you know, that kind of stuff. This here is manageable. Um, you know, if you have a life, I have eight grandchildren, you know, we're always busy with the grandchildren, and I can't be at the gym three times a day like I did before. So this definitely is a program that you can work with, you know, um, having other activities that also need to be, um, dealt with. So yeah, I, I... Mastering Diabetes has definitely changed my life. I would ask them to give themselves the investment of a lifetime and to get into the Mastering Diabetes program. It definitely works. Okay. Um, before starting Mastering Diabetes, my, um, A1C went from 7.1 to 5.4. I did, after, um, deciding that I would, on my own, quit eating all the bad foods that we have access to out there, I ended up trying theMastering Diabetes program on my own. Didn't have any coaching. Um, and for a week, I ate plant-based. I got rid of all the stuff in my pantry. Um, and after a week when I went to do blood work... It just so happened I was doing blood work, which I'm glad everything fell into place the way it did. Um, I was taking metformin twice a day, 500 milligrams, and my doctor asked me what I was doing because my numbers had dropped significantly since our, our last visit, which was a year or six months before that. And I told her that I stopped eating all the junk foods and that I was eating, you know, grains and beans, the whole nine yards. And she, um, said I needed to continue doing that, and that she was taking me off of the metformin. So I went from that to an injection once a week, and I actually go back to see her in a couple of months, so hopefully that will be taken off-- I'll be taken off of the injections. So since the Mastering Diabetes program, I have stopped metformin medications, and hopefully I will be taken off of the other medications. [laughs] The, um, Mastering Diabetes program is 100%, 100% an investment to the rest of your life, and knowing that I am able to wake up in the morning and check my blood sugars and they're not 130, 120, um, it means a lot. It's actually an easier approach. Um, I mean, I have cut up vegetables in the refrigerator. I have, you know, fruits. I mean, it's not sitting in your kitchen two hours cooking a meal that takes two hours. You know, everything's accessible there for you to eat raw. The plant-based approach was a lot easier than I anticipated. Very easy. I actually, um, did feel a difference when I was on the metformin. Um, I, I, I am not a person that likes taking medications to begin with. Um, first time I ever started taking medication is when I had my stroke, so, um, knowing that I was taking these medications was already in my mind that I didn't wanna take them. But I think this is heading me into the right direction of not having to take medications or continu- continuing to get off of the medications that, um, I'm not crazy about taking. I felt, after getting off of the medication, I felt less inflammation, if that makes sense. Honestly, I, I h- have none of that. I mean, I am very active. Um, I have a garden. I like being outside in the garden with my flowers, so I, nothing really stops me. [laughs] But I do feel 100% better. Like, um, mental clarity, that is definitely much better.
