Is a Keto Diet Safe For Prediabetes And Insulin Resistance? (COVID-19 update)

Is a Keto diet safe for Prediabetes and Insulin Resistance? Find out here...AND learn the 3 Truths You Need To Know BEFORE you decide if a Keto diet is best for you.


A lot of ladies in my Healthy U Group are Keto survivors.

What do I mean by this?

Well, they did the keto diet and made themselves worse. In some cases, a lot worse, including becoming Type 2 Diabetic!

Now, when you're already sick, having to fix even more health issues doesn't sound like fun to me.

So...what's the allure with the Keto diet? Why do so many women try it?

Simple. The Keto diet makes you lose weight...fast!

For the millions of ladies out there who are so damned tired of their weight problems, the Keto diet seems like they've won the lottery.

Problem is – they haven't.

Why? Well, let me explain.

First, I'll briefly tell you about the Keto diet (in case you don't know what it is yet).

Then I'll reveal to you the 3 Truths about what you'll get yourself into if do the Keto diet.

(If you do decide to try the Keto diet, do yourself a big favor: bookmark this page – I'm pretty sure you'll want to read this post again in a few months when you're pretty upset with your test results.)

What is a Keto Diet?

A Keto diet (also called ketogenic or Low Carb High Fat {LCHF} diet) is a very low carb diet which only allows you to eat:

  • About 20 - 30 grams of carbohydrates a day
  • Limited protein
  • Primarily fat

How is a Keto Diet Different?

No matter what diet you're on, your body needs fuel.

This fuel usually comes primarily from carbohydrates, then protein, and lastly fat.

But not so with a Keto diet.

A Keto diet gives you VERY limited fuel from carbohydrates (since you can't eat many of them).

So what happens?

With very limited fuel from carbohydrates, your body has to get fuel from somewhere else.


Well, the Keto diet takes advantage of an emergency backup fuel in your body called ketones.

Ketones are produced in your body when fatty acids are broken down (the fancy term is 'metabolized').

And here's the thing ladies love about all this: using ketones for fuel usually promotes rapid weight loss.

Why Do People Like The Keto Diet?

These are 3 benefits that the Keto diet tribe boasts about:

  1. By reducing the amount of glucose in your blood, you reduce the amount of insulin you produce, so you store less fat (Actually, this is only partially true...I'll explain this more below)
  2. A Keto diet makes you lose weight very quickly (Sounds good, right? Actually, it's a terrible idea! Rapid weight loss = rebound weight gain...more on this below)
  3. A Keto diet will usually rapidly lower your A1C, fasting insulin, and blood glucose (Unfortunately, these results distract you from knowing what's really happening in your body...the good news is you can easily discover the truth, which isn't pretty...more on that below)

Those are the 3 Keto diet benefits...

...but as you can already see, there are also serious problems with them.

"The 'best' way to lose weight fast is to do something very silly, unsustainable and arguably irresponsible. It's not truly best -- just fast...

Many things that are truly bad for health can cause short-term weight loss...

The most effective diets for 'fast' weight loss impose severe restrictions that cannot be maintained and would not be compatible with health if they were."

Dr. David Katz, Yale University Prevention Research Center

So let's dive into those problems now and reveal the 3 Truths about what you'll get yourself into if do the Keto diet.

Ready to admit rapid weight loss and fad diets don't work?

Our Healthy U Group offers a sustainable lifestyle you can stick to for life...

Truth #1: Insulin Does More Than Control Your Blood Glucose

Keto dieters want their insulin levels to be as low as possible.


Because they claim that even small amounts of insulin will make you gain weight.

Is that correct?

Well, insulin DOES tell your body to store fat...BUT the insulin in your body will NOT make you fat if you aren't eating more calories than you need.

So if you want to lose weight, trying to get your insulin level down isn't your best bet.

Especially since it's TOTALLY natural and good for you when your body makes and releases insulin.


Because insulin's MOST IMPORTANT JOB is to help move glucose into your cells so you have energy to do the stuff you want to do.

But wait! Insulin also does many more things – things you need to survive!

  • Insulin helps move fatty acids into your tissues to be used or stored. When you're sick or starving, this stored fat comes in very handy. In other words, having normal amounts of body fat is NOT bad. (So you know, normal body fat for a woman under 40 is 25%)
  • Insulin helps build your muscle tissues. (Why else do you think body builders inject insulin?)
  • Insulin keeps your brain working properly, including memory and thinking (super important!)

Looks like insulin isn't so bad after all!

Now, it's correct that a low-carb Keto diet WILL give you lower insulin levels after you eat...BUT your body will still make insulin and use it, Keto diet or not.

You simply can't be alive without your body producing and using insulin.

In other words, insulin is your friend. So don't try to make your friend go away.

Truth #2: Rapid Weight Loss Is A Terrible Way To Lose Weight

The faster you lose weight, the more likely you are to gain it all back – and with a vengeance.

The reason for this is your metabolism.

Your metabolism is wired to gain back fat that you've lost.

And we all know that gaining back all your weight is incredibly depressing.

Unfortunately, that's the reality you face when you lose weight rapidly on a Keto diet. Your chances of gaining it all back are almost 100%.

U.S. News & World Report

 Best Diets Overall:

2020 update

Every year health experts rank all the popular diets. This year the keto diet ranked 34/35 (so it was almost dead last).

  • Is the keto diet healthy? Nope! it ranks 1.8/5.0!
  • Is the keto diet easy to follow? Nope! it ranks 1.4/5.0!
  • Is the keto diet a solution for long-term weight loss? Nope! It ranks 2.2/5.0

Truth #3: Low A1C and Low Fasting Insulin Doesn't Mean You're Healthy

It's correct that eating a Keto diet CAN drastically lower your A1C and Fasting Blood Glucose and Fasting Insulin.


Because you can easily manipulate those numbers by eating a very low carb diet.

But that doesn't mean you've reversed your Insulin Resistance!

If you eat a Keto Diet...

Low fasting insulin DOES NOT mean you are NOT insulin resistant.

Don’t believe me?

Then take an Oral Glucose Tolerance Test and see what happens (that's the test where you drink the sugary liquid).

Why will an Oral Glucose Tolerance Test reveal the truth about your Insulin Resistance?

Because the way to know how sensitive you are to insulin is to eat glucose.

(That's why you drink sugar when you take this test.)

If you are truly sensitive to insulin (in other words, if you are NOT insulin resistant), then your Oral Glucose Tolerance Test will confirm this.

In many cases, diehard Keto dieters take the test and are shocked to find out they have full-blown Type 2 Diabetes.

Don't let that be you!

As well!

The A1C test has been proven to be a terrible indicator of your overall glucose tolerance!

In a study of over 9000 people 73% of cases of Diabetes were missed with the A1C test!

  1. A new 2019 study included 9,000 adults without a diabetes diagnosis.
  2. The participants got both an A1c test and an oral tolerance glucose test, and the researchers compared the results.
  3. The researchers found the A1c test didn't catch 73 percent of diabetes cases that were detected by the oral glucose test. 

"The A1c test said these people had normal glucose levels when they didn't."

"Ketogenic diets impair higher order cognitive function. In a randomized weight loss study comparing a ketogenic with a nonketogenic hypocaloric diet, subjects consuming the ketogenic diet had impairments in higher order mental processing and flexibility than those following the nonketogenic diet."

Is Keto A Good Idea When You Have COVID-19?

No! Why?

Anytime you have a viral infection your body goes into stress mode and you become more insulin resistant. (this is a normal reaction)

Viral infections CAN also induce new onset Diabetes (which means you get Diabetes because your body was fighting off a bad viral infection).

The keto diet already causes your body to go into stress mode...AND causes insulin resistance... so you'll just make your health worse if you eat a keto diet while you have COVID-19.

You need to eat a VERY healthy diet heavy on fruits, veggies and whole foods to fight off ALL viral sicknesses...crazy fad diets, like keto, are the WORST thing you could eat when you are sick.
