Meet Hemant. When he arrived at the Mastering Diabetes Retreat, he felt like he had hit a wall.

His journey with diabetes had started more than two decades earlier. In 2001, routine blood work showed an A1c around 6.0% to 6.1%, and he was told he had prediabetes. At the time, he didn't make significant changes.

Four years later, everything changed.

Hemant found himself in the emergency room with glucose around 550 mg/dL and was diagnosed with type 2 diabetes.

From that point forward, he worked to improve his health through diet, exercise, and changes in mindset. His glucose gradually came down from that frightening high, but eventually his progress stalled with readings around 220 mg/dL.

He knew he needed something different.

At the Mastering Diabetes Retreat, Hemant finally experienced the breakthrough he had been looking for. His baseline glucose dropped by approximately another 50 points, while his Time in Range increased from roughly 4% to 5% before the retreat to 28%.

But when Hemant talks about what changed during those few days, the numbers aren't the first thing he wants people to remember.

The biggest transformation was going from fear to confidence.

Years of Progress Until He Hit a Wall

Hemant had already made significant progress before arriving at the retreat.

After his type 2 diabetes diagnosis, he made a conscious effort to improve his health. He changed his diet, exercised, and worked on his mindset. Over the years, he watched his glucose come down substantially from the 550 mg/dL reading that had landed him in the emergency room.

Eventually, however, his progress stalled.

His glucose remained around 220 mg/dL, and despite everything he had already done, he couldn't seem to get beyond that point.

At the same time, his continuous glucose monitor was showing how much room there was for improvement. Hemant estimated that his Time in Range was typically only about 4% to 5%.

He wasn't giving up, but he was beginning to feel lost.

The Mastering Diabetes Retreat gave him an opportunity to remove himself from his normal routine and experience a different way of approaching his diabetes.

Within days, the results began changing.

Hemant's Retreat Results

The results would exceed his expectations.

Before

Time in Range around 4% to 5%

Time in Range reached 28%

Baseline glucose around 220 mg/dL

Dropped by approximately 50 mg/dL

Progress had stalled

Numbers moving again

Felt lost and afraid

Felt confident and hopeful

Unsure of his direction

Clearer path forward

The increase in Hemant's Time in Range was especially meaningful. Going from approximately 4% to 5% to 28% showed him that his glucose patterns could change when he consistently applied what he was learning.

His baseline glucose also fell by approximately another 50 mg/dL during the retreat.

Hemant was excited about those numbers, but he viewed them as the beginning rather than the final destination. What mattered most was that the experience showed him a path he believed he could continue following at home.

From Fear to Confidence

Hemant describes his mindset before the retreat as feeling like a deer caught in headlights.

He could see the problem in front of him, but he wasn't sure what to do next.

Why was this happening? What should he change? Where was his health headed?

At the Mastering Diabetes Retreat, those questions began turning into something much more constructive: Direction.

Hemant started seeing that there were specific actions he could take every day. The immersion allowed him to experience those actions repeatedly, rather than simply hearing about them and then returning to his normal environment.

“This immersion has shown me a new way to live.”

The experience also made Hemant think differently about his own worth.

Was his health important enough to take action for? Was he willing to give himself the same urgency and care he would give someone else he loved?

By the end of the retreat, his answer was yes.

Hemant described the transformation simply: he had moved from a place of fear to a place of confidence.

Seeing His Blood Sugar Respond in Real Time

One of the biggest surprises for Hemant was how quickly his glucose responded.

He had spent years working on his diabetes and had eventually reached a point where further progress felt extremely difficult. At the retreat, he experienced noticeable changes within only a few days.

That immediate feedback helped connect the education with what he was seeing on his CGM.

Hemant also came away with a new understanding of the Mastering Diabetes Method to insulin resistance. In particular, he learned why the program emphasizes reducing dietary fat while increasing whole carbohydrate-rich plant foods.

He removed much of the fat that had been part of his normal diet and watched his glucose patterns begin improving.

For Hemant, experiencing that change personally was far more powerful than simply hearing about the concept.

He was eating. He was satisfied. And his numbers were moving in the direction he wanted.

From Overwhelmed by the Food to Going Back for Seconds

The amount of food was another surprise.

When Hemant first saw the portions at the retreat, he thought they were excessive. He couldn't imagine eating that much food while simultaneously trying to improve his metabolic health.

Four days later, his perspective had completely changed.

Not only was he no longer overwhelmed by the portions, he was going back for seconds.

The experience helped him understand calorie density in a practical way. Instead of focusing on tiny portions, he could eat generous amounts of low-fat, whole plant foods and still work toward his health goals.

Hemant liked the system so much that he bought four bowls like the ones used at the retreat.

He planned to take them home as a practical reminder of what appropriate meals could look like.

That small detail represented something larger about the retreat experience.

Hemant wasn't leaving with abstract information. He was leaving with routines he could recreate.

Coaching That Felt Personal Instead of Textbook

The coaches were another major part of Hemant's transformation.

He had spoken with physicians and other diabetes counselors before, but he described much of that guidance as a textbook approach.

The retreat felt different.

Hemant experienced one-on-one attention, proactive support, curiosity, and genuine care. Instead of receiving generalized advice, he felt the coaches were trying to understand his individual situation and help him find solutions he could actually use.

For Hemant, that relationship helped build confidence.

He wasn't simply being told what he should do. He was being guided through the process while seeing his own glucose respond.

That combination of education and personal support helped him believe he could continue after returning home.

Realizing He Wasn't Alone

The community became equally important.

Living with diabetes can feel isolating, particularly when the people around you don't fully understand what it's like to watch your glucose numbers, worry about your future, and wonder whether you're making the right decisions.

At the retreat, Hemant was surrounded by people asking many of the same questions. That created an immediate sense of camaraderie.

“The number one thing is to know that you're not alone.”

For Hemant, being surrounded by peers reduced some of the fear he had carried into the retreat.

He could talk with people facing similar challenges. He could learn from coaches who understood the experience. And he could see other participants beginning to change their own relationship with their health.

One conversation in particular reinforced the lesson Hemant was learning himself: taking care of your health requires believing that you are worth taking care of.

That realization became part of what he planned to carry home.

What Hemant Wants Others to Know

When Hemant arrived, his Time in Range was approximately 4% to 5%, his glucose had stalled around 220 mg/dL, and he wasn't sure how to move forward.

During the retreat, his Time in Range reached 28% and his baseline glucose dropped by approximately another 50 mg/dL.

But Hemant doesn't define the experience by those numbers alone.

He found direction where he had felt lost. He found community where diabetes had felt isolating. He experienced personalized coaching instead of generalized instructions.

And he discovered that a lifestyle built around low-fat, whole-food, plant-based meals could leave him eating generous portions while his glucose improved.

Most importantly, he left believing he could continue.

Hemant describes the retreat as an investment in health because its value isn't limited to the days spent there. The goal is to take the routines, education, confidence, and mindset home and continue applying them to everyday life.

By the end of the retreat, Hemant had already told his wife that things were going to change.

He was committed.
