Jeff’s life was burdened by type 2 diabetes for over a decade. Despite being an active person, he struggled to control his blood glucose levels and experienced constant fatigue. Determined to break free from the cycle of medication and health struggles, Jeff discovered the Mastering Diabetes Method and coaching program. 

In this blog post, we delve into Jeff's inspiring success story and how he achieved a remarkable transformation, conquering type 2 diabetes and finding newfound vitality through the power of plant-based nutrition.

A Turning Point

Jeff recognized that his diabetes management needed a complete overhaul. He sought a solution that addressed the root cause of his health issues, which he suspected were connected to his dietary choices. The Mastering Diabetes Method provided the perfect opportunity for him to take control of his health, embark on a transformative journey, and rediscover a zest for life.

The Mastering Diabetes Coaching Program

Jeff's commitment to the Mastering Diabetes coaching program proved to be pivotal in his success. Working with his coach, Linda, provided him with the support and guidance he needed to navigate the lifestyle changes effectively. The program's emphasis on accountability and tailored meal plans helped Jeff build a strong foundation for a sustainable and rewarding health journey.

Embracing the Plant-Based Lifestyle

Switching to a whole-food, plant-based diet was a significant adjustment for Jeff. However, the six-week meal plan provided him with a clear roadmap to reset his eating habits and explore new, delicious, and nutrient-packed plant-based dishes. As Jeff discovered a world of flavors and spices, he found that this lifestyle change was far from restrictive; it was an opportunity for culinary exploration and enjoyment.

Reaping the Benefits

Jeff's commitment and dedication to the program paid off in numerous ways. He experienced a remarkable weight loss of 38 pounds in just six months, which not only boosted his confidence but also reduced the aches and pains he used to feel. As his physical appearance improved, so did his internal health. Jeff's blood work reflected significant improvements, with his A1C levels dropping from a worrisome nine to a much healthier 5.4. Additionally, his cholesterol and blood pressure medications were halved, and he witnessed his cholesterol levels drop from 220-250 to a remarkable 140.

An Active and Fulfilling Life

With newfound energy and improved well-being, Jeff embraced an active lifestyle once again. He joyfully participated in obstacle courses, mud runs, and other physically demanding activities that were previously challenging. Jeff's ability to run five miles and enjoy the outdoors with his children became a source of pride and motivation. These experiences also served as reminders of how far he had come on his health journey.

Sharing the Success

Jeff's remarkable transformation not only inspired him but also those around him. Friends, family, and acquaintances noticed the positive changes in Jeff's health and appearance, and he willingly shared the Mastering Diabetes program with anyone who expressed curiosity. Jeff's enthusiasm and commitment to pay it forward became evident, as he gifted the Mastering Diabetes book to loved ones, encouraging them to embark on their journey to better health.


Jeff's success story showcases the transformative power of the Mastering Diabetes Method and coaching program. Through dedication to a whole-food, plant-based lifestyle, Jeff conquered type 2 diabetes, shed excess weight, and experienced a profound improvement in his overall well-being. Jeff's journey serves as an inspiration to others seeking a path to better health and vitality. 

His story emphasizes the importance of taking charge of one's health, finding support in the right places, and embracing the benefits of plant-based nutrition for a life full of energy, happiness, and well-being.
