Discover the Proven Method That Has Improved the Lives of Thousands of People in This 6-Week Challenge

The 6-Week Blood Sugar Transformation Challenge gives you the knowledge, power, community, personalization, and inspiration to become the most insulin sensitive you've ever been

This Challenge is For You if You've Experienced Any of the Following Problems

You've tried everything, but your blood sugar and A1c are constantly high

  • You’ve been trying hard to lower your A1c for years, and feel like you just want to give up
  • It seems like you’re constantly guessing at what is truly affecting your blood sugar, and getting more and more frustrated over time
  • This constant guesswork isn’t getting you the results you truly want, no matter how hard you try

You're frustrated that you can't lose weight, and are tired of feeling hopeless

  • You’ve tried every “diet” on the planet, and have shed weight but gained it all back many times
  • You’re frustrated with seeing high numbers on the scale, which make you feel hopeless and ready to give up
  • You’re sick of calorie counting, portion control, and starving yourself, and want to eat normally, the same way your friends and family do

You don't know what to eat to control your blood sugar (without getting frustrated)

  • You feel like you’ve tried every diet on the planet, but no matter what you eat, your blood sugar is high. 
  • Even when you lower your carb intake, your blood sugar and/or insulin use go up, causing more and more frustration every day. 
  • The mere thought of eating foods like fruits, potatoes, and whole grains scares you, even though you frequently daydream of eating them.

You don't now what to eat to lower your blood sugar and A1c ... without guessing

  • It seems like no matter what you eat and no matter how hard you try, your blood sugar and A1c are high
  • You’ve followed the conventional wisdom of eating less carbs, but your blood sugar meter is constantly showing you a high number
  • You avoid eating foods like fruits, potatoes, and whole grains like the plague, even though you secretly daydream of being able to eat them again

You feel like you're on the "medication train to nowhere" with no end in sight

  • You avoid going to the doctor because you’re afraid that they’ll increase your meds
  • Your doctor constantly increases your dosage and adds one medication after another in an attempt to get your blood sugar under control
  • Multiple medications cause frustrating side effects like nausea, fatigue, bloating, skin rashes, nerve tingling, low energy, kidney damage, blurred vision, and brain fog
  • You know that medications are just a “band aid,” but you’re looking to reverse the underlying cause of high blood sugar instead

You don't know EXACTLY how much basal or bolus insulin to inject

  • Every time you sit down to eat a plate food, you feel like you’re guessing at how much insulin to inject
  • 24 hours a day, you’re “on call” as you watch your blood sugar rise and fall, frequently injecting correction boluses that create a rollercoaster of highs and lows
  • You inject a “rage bolus” because you’re tired of seeing your blood glucose meter or continuous glucose monitor (CGM) show erratic patterns

Karin Yehling

Health Coach

Karin has watched 4 generations of family members get diagnosed with type 2 diabetes; including herself. She was diagnosed at the age of 35 while she was a competitive racquetball player. Luckily, she was able to make enough changes to get her A1C back to normal relatively quickly. However, a whole food plant based diet was NOT on her radar so her numbers started creeping back up again. Using the Mastering Diabetes method has proven itself with a diabetes reversal once again (the right way this time).


Karin spent over 20 years in the health and fitness field as a personal trainer and realized that food is the foundation of health. So, she set off to get her Nutrition Coach certification from Precision Nutrition and then her Health Coach certification from Functional Medicine Coaching Academy. Her passion is to empower people with the knowledge and skills to make diabetes a thing of their past using food as medicine in the form of a low fat whole food plant based diet. As she guides you on your journey to health, rest assured that Karin has been on this journey as well, and knows how life-changing it can be to reclaim your health.
