High Blood Glucose on Keto

author avatar Dr. Eric Berg 10/15/2023

Have you ever questioned why your blood sugar increases on a keto diet? It's like trying to put out fire with gasoline, right?

The answer lies in the complex dance of insulin and glucose. Like partners who've lost their rhythm, they stumble and trip, leading to high blood glucose levels.

This is not just another health scare story but a journey into our bodies' intricate workings.

We'll unmask how insulin can deceive us into believing everything's okay when it isn't. Then, we’ll dive deep into the surprising effects of long-term insulin resistance - something akin to pancreatic exhaustion.

We won't leave you hanging there, though! Discover how switching lanes from unhealthy eating habits towards a ketogenic diet coupled with intermittent fasting can help fix this mess!

Just a heads-up: You may hit some bumps along the way, like a temporary rise in blood sugar. But don't worry, stay strong and hang tight!

Insulin resistance, a frequent health concern, is frequently disregarded. It's where the body doesn't respond to insulin as it should. Research shows up to 34% of US adults suffer from this condition.

But what does this mean? Picture insulin as a key that unlocks cells so glucose can enter and provide energy. In people with insulin resistance, these keys don’t work correctly. The locks (cells) reject them.

The body reacts by producing more insulin to force the glucose into cells for use or storage - think of it like using a battering ram when your key won't open the door.

Elevated insulin levels in the bloodstream, known as hyperinsulinemia, can hide an underlying issue with sugar metabolism.

The Masking Effect of High Insulin Levels on Blood Glucose

High insulin levels can mask the real story behind your blood sugar. Let's delve into this paradox.

How does our body's insulin production affect blood glucose levels when we consume unhealthy food? Typically, you'd expect a spike in glucose. But surprisingly, if your body produces high amounts of insulin, it might maintain normal blood glucose levels.

This is due to the masking effect - an overworked pancreas producing more and more insulin to get by. While initially effective at keeping sugar down, it’s not a sustainable solution.

The pancreas eventually tires out, leading to higher blood sugars – the very thing it was trying to prevent.

Pancreatic Exhaustion and Elevated Blood Sugar Levels

When insulin resistance persists, the pancreas can become overworked. This is similar to a factory always on overtime - eventually, it gets tired. The constant insulin production leads to what we call 'pancreatic exhaustion.'

This fatigue isn't just about your pancreas needing a nap; it has severe implications for blood sugar levels. Over time, as the pancreas struggles, its ability to produce enough insulin decreases.

Imagine insulin as traffic officers directing cars into parking lots. But what if they're suddenly not there? You'd end up with a bunch of 'cars' (glucose in this case) roaming, leading to high blood sugar levels because the glucose has nowhere specific to go.

The Ketogenic Diet and Intermittent Fasting as a Solution

By reducing carbohydrate intake, a ketogenic diet can help to combat insulin resistance. But why does Keto work? When you reduce your carb intake, your body turns to fat as an alternative energy source. That’s where fat comes in.

Your body starts burning fats instead of glucose for fuel—a state known as ketosis. This switch reduces the need for insulin since less glucose is available in the bloodstream.

Less demand means lower levels of circulating insulin—helping alleviate some effects of insulin resistance.

The Transition Phase in Dietary Changes

Starting a keto diet isn’t all sunshine and rainbows—it requires significant dietary changes that may initially cause an increase in blood sugar levels. This rise is temporary but vital because it signifies that your body is adapting to its new energy source: fat.

This phase might seem scary with higher-than-normal blood sugar readings; don't let these numbers discourage you. It's part of the journey towards healthier living through reduced carbohydrate reliance.

The Significance of Rising Blood Sugar Levels During Transition

It's like moving to a new city. You've got boxes everywhere, and things are in disarray - but it’s part of the process.

Your body adjusts to burning fat instead of glucose for energy, causing temporary high blood glucose levels. But don't fret. This rise isn’t harmful; it signifies your insulin levels are getting healthier.

This shift indicates that you're on track toward fixing your insulin resistance. So even though those numbers might seem alarming at first glance, remember: they're just a signpost along the road to better health.

Stabilizing Blood Sugar Levels Over Time

Shifting to a ketogenic diet and intermittent fasting may initially trigger a rise in blood sugar levels. No cause for concern; this is just a sign of your body adapting to the new diet. Instead, it's your body adapting to the dietary changes.

Your body previously relied on carbohydrates for energy, but now you're asking it to switch gears and burn fat instead. It’s like moving from gasoline to diesel – there might be some hiccups at first.

This transition phase doesn't last forever, though. Insulin resistance starts improving as you stay consistent with keto eating habits and periodic fasting.

Blood glucose levels fall back into healthier ranges as your pancreas gets less taxed. The key here is consistency - stick with it.


So, you've been on a rollercoaster ride understanding the causes of high blood glucose on keto.

The role insulin plays in our bodies is more than just regulating sugar. It's about keeping balance.

We now know insulin can mask unhealthy habits, giving us false security until it leads to pancreatic exhaustion and soaring glucose levels.

But there's hope! Switching to a ketogenic diet and intermittent fasting could be your ticket out of this mess. Remember, though, expect some bumps during the transition phase - like temporary spikes in blood sugar levels.

This isn't an overnight miracle but a journey towards better health with consistent practice and patience!

Your body will thank you for taking this bold step toward stability!
