Your questions pour in from all platforms, but I answer them best in our 21-Day Metabolic Kick (21DMK) class—held twice a year. The February class was our best yet, with students transforming their metabolisms in just three weeks.

These emails come from the questions asked inside the class. If you find this email valuable, forward it to a friend who wants to learn about the authentic ketogenic lifestyle. Let’s reach more people who are ready to take control of their health!

Q: Why is my fasting blood glucose still elevated during prolonged fasting (48+ hours), and how can I reverse this persistent insulin resistance without medications?

It’s disheartening to fast for 48 hours and still see high glucose readings. You’re not alone in this struggle, and there’s a clear explanation rooted in science—along with a practical solution. Let’s break it down.

David’s Experience: A Common Frustration

David joined our 21-Day Metabolic Kick after a 48-hour fast, expecting progress. Instead, his morning glucose lingered at 110. He felt defeated, questioning if change was possible. This disconnect between effort and results is widespread—and it’s not a reflection of your willpower. The culprit? Insulin.

The Science: Insulin Locks Away Fat

Research on severely obese patients offers a revealing lesson: insulin resistance keeps glucose high and fat burning off-limits, even during long fasts. In studies, patients fasted for up to five weeks with only water and salt. Their glucose stayed elevated for days, and ketones—markers of fat burning—took weeks to appear. Why? Excess insulin forced their bodies to break down muscle and bone instead of tapping into abundant fat reserves.

Fasting alone can’t overcome this hormonal barrier. You need to lower insulin first.

Your Action Plan: Reverse Insulin Resistance Naturally

Here’s how to take control without medications:

1. Fuel with Fat: It sounds surprising, but eating healthy fats (like avocado or olive oil) supplies energy without raising insulin. This helps your body start burning stored fat.
2. Track Your Progress: Use a glucose and ketone meter to calculate your Dr. Boz Ratio (DBR)—a proxy for insulin levels. Aim for a DBR below 40.
3. Delay Fasting: Avoid prolonged fasts until your insulin stabilizes. Begin with a high-fat, low-carb diet to reset your metabolism.
4. Ease Into Fasting: Once your DBR improves, add short fasts or time-restricted eating(e.g., 16:8) to boost fat loss.

Key Principle: “Ketones rise first, glucose falls second.” Prioritize raising ketones through diet before expecting glucose to drop.

Why It Works

Insulin resistance doesn’t heal overnight. By eating fat strategically and monitoring your metrics, you’ll lower insulin, unlock fat stores, and set the stage for successful fasting. David turned his results around by stabilizing his metabolism first—only then did fasting pay off.
