Meet Vivian. She had struggled with her weight for most of her life.
Although she had never been diagnosed with diabetes, everything changed after she suffered a stroke in 2018. As doctors searched for the cause, they discovered her blood sugar was elevated and diagnosed her with prediabetes.
Like so many others, she was referred to a dietitian and advised to cut back on carbohydrates. But despite following the conventional advice, she still felt like something was missing.
She wanted a solution that addressed the root cause—not one that simply helped her manage higher blood sugar.
Searching for a Better Answer
After her diagnosis, Vivian spent years trying to improve her health.
In 2020, she came across one of Robby Barbaro's YouTube videos and began learning about the Mastering Diabetes approach. The science immediately resonated with her.
Instead of fearing carbohydrates, she learned how improving insulin sensitivity could help her body use them more effectively.
Motivated by what she learned, Vivian began making changes on her own. She cleaned out her refrigerator and pantry, got rid of processed foods, and started filling her kitchen with beans, lentils, quinoa, fruits, and vegetables.
Even before officially joining the Mastering Diabetes Coaching Program, those changes began moving her A1c in the right direction.
Taking the Next Step
Eventually, Vivian decided to fully commit to the Mastering Diabetes Coaching Program.
Although she had already transitioned to eating about 75% plant-based, she admits the program still felt overwhelming at first. What kept her moving forward was discovering her "why."
Once she focused on the life she wanted to live, making healthier choices became much easier. Within just a week and a half of following the program consistently, she noticed something exciting.
Her daily blood sugar readings started dropping. That was the confirmation she needed that she was on the right path.
Vivian's Before and After Results
The improvements continued over the following months.
Header | Before | After |
|---|---|---|
A1c (%) | 7.1 | 5.4 |
Weight (lbs) | 194 | 174 |
Metformin | 500 mg twice daily | NONE |

For Vivian, one of the biggest victories wasn't just lowering her A1c. It was no longer needing Metformin.
She also hopes to continue improving her health enough to reduce or eliminate additional medications in the future.
Perhaps just as meaningful, her morning blood sugar readings are no longer in the 120–130 mg/dL range when she wakes up.
For the first time in years, she feels confident about the direction her health is heading.
A Lifestyle That Fits Real Life
Before discovering Mastering Diabetes, Vivian believed improving her health meant spending hours at the gym.
She had tried exercising multiple times a day, but it simply wasn't sustainable. As a grandmother of eight, her days are busy. She needed a lifestyle that fit into real life.
That's exactly what she found.
Meal prep became simple. Fresh fruit and cut vegetables were always available. Beans, lentils, and whole grains became everyday staples.
Instead of spending hours preparing complicated meals, healthy food became easy, accessible, and enjoyable.
Most importantly, the program allowed her to prioritize her health while still enjoying time with her family.
What Vivian Wants Others to Know
Looking back, Vivian says joining Mastering Diabetes was one of the best investments she has ever made.
She encourages anyone struggling with type 2 diabetes or prediabetes to give themselves the opportunity to experience what's possible.
For her, the program wasn't just about lowering blood sugar. It was about creating a healthier future.
Today, she wakes up knowing her blood sugar is under control, feels more confident in her food choices, and has discovered a sustainable lifestyle she believes she can follow for years to come.
Her message is simple: Invest in yourself. The results are worth it.
