The interview
Can you introduce yourself and describe your situation before starting the program?
My name is Susan Waters, and I live in Benicia, California. I have Type 2 diabetes, and I was diagnosed probably about 15 years ago. I was going in a lot of different directions, following one program then another, lacking consistency and a good overall plan that explained why a certain method would work.
What was the wake-up call that led you to seek a new solution?
I have a friend who is going blind, and I became very concerned about my eyesight, and I realized that diabetes can affect it. This was the wake-up call that I needed.
What were your health markers and medications right before starting?
My A1C was 8.4. I was on Glucophage, 1,000 milligrams twice a day, and on insulin. I was taking probably about 30 to 40 total units a day of NPH/Lantus, and then the rapid-acting insulin was probably about 30 to 40 units a day total, so quite a lot.
How did you first react to the Mastering Diabetes approach?
I saw the book in a bookstore and I thought, 'These people are idiots. They're telling you to eat more carbs to control your diabetes.' I thought it was so stupid that I got intrigued and started reading it. It went against everything I had learned, but it made sense, and I thought I had nothing to lose by trying it.
What were your initial results after starting the program?
I could not believe the difference that it made. I came way, way down on my insulin very, very quickly. Even over the first few weeks, I could see the changes already. I was lowering my insulin, I was feeling like a person, and I wasn't super hungry during the day. I could eat a banana if I wanted.
How has your life changed since working with Mastering Diabetes?
My life has gotten less chaotic and more sane. I feel more in control of my health and other aspects of my life because of the holistic approach involving exercise, sleep, and stress. My energy level has improved; I used to plan my naps as soon as I woke up, and now I feel like I'm 20 years younger.
What are your current health numbers and medication status?
My A1C is down to 7.1 from 8.4. I'm still taking the Glucophage, but I have decreased my insulin significantly. I am down to 6 to 8 units of Lantus a night and maybe less than 10 units of the rapid-acting in a day.
What is your opinion of the coaching and community resources?
The coaches are invaluable; I've been using Wendy and she's fantastic. One thing I noticed about all the coaches is their skin is radiant; you can tell they are healthy. I also love the online support, the recipes, and the community chat. The amount of material online is incredible.
Frequently asked
Does eating more carbohydrates actually help control diabetes?
Susan Waters initially thought the idea of eating more carbs to control diabetes was 'stupid' and 'counterintuitive.' However, after reading the Mastering Diabetes book and starting the program, she found her blood sugar actually came down after eating carbs like bananas because the method addresses the underlying pathophysiology.
Is the Mastering Diabetes program worth the financial investment?
Susan Waters initially started the program on her own using the book due to the cost. After seeing it work, she decided to make the 'financial sacrifice' for the full coaching program and now states it was worth it because it gave her her life back.
Can you still see results with Mastering Diabetes if you have other health setbacks?
Yes, Susan Waters continued the program even after a cancer diagnosis and treatment. While she noted her progress might have been even more significant without that setback, she is still very happy with her A1c drop from 8.4 to 7.1.
