My Review: The Diabetes Code – Does It Work? (2024)

It’s time to review The Diabetes Code – which is a pretty interesting book.

Is it actually effective for high blood sugar?:

  • quite popular
  • more of a general diabetes book
  • not applicable to most cases

At first sight, this book looks pretty good.

But let's find out if it's really worth it, in the following lines.

Note: This review is based on my opinion + research on The Diabetes Code.

Review Summary

review the diabetes codeFull Name: The Diabetes Code by Dr. Jason Fung

Product Type: Diabetes/Blood Sugar Book

Best Actual Prize: Around $10 (for the softcopy)

Cheapest Place To Buy: Amazon

Designed For: Preventing diabetes – it claims to:

  • reverse diabetes
  • promote dieting
  • focus on intermittent fasting

My Rating: 6 out of 10

Recommended?: Not really – it's not bad, but it's far from amazing:

  • some tips are not for all diabetes sufferers
  • focused on general facts about diabetes
  • lacks some important info

If you really want an improvement in your diabetes, it's much better to go for an internal product

There's a huge difference (in terms of results) between it and this book.


What I Liked About It

  • Divided in 15 chapters
  • Its author has a decent background in this field
  • Available in several versions
  • A lot of authentic reviews are available


What I Didn’t Like About It

  • Little info about its program
  • Most content is focused on general diabetes info
  • Diet tips are not suitable for everyone (especially intermittent fasting)
  • Could cost even less for its value
  • Not very safe (compared to other books/courses)



The Diabetes Code In A Nutshell

review the diabetes codeIn my opinion, The Diabetes Code is a decent book.

It offers a lot of chapters that talk about diabetes.

But there's very little content about the actual program it recommends.

So most of this book is focused on general info about diabetes.

Honestly – you can find all that on the internet (for free).

Also – there are some downsides about it:

  • more dangerous diet plan (than other courses)
  • pretty expensive in reality
  • program approach is not suitable for all
  • very little tips and recommendations

Now – this book is focused on intermittent fasting for diabetes.

Some people might find this diet effective in losing weight.

But I wouldn't recommend it for diabetes:

  • not really safe
  • its diabetes results aren't really worth it

Honestly in a worst-case scenario, intermittent fasting can even put your health in danger.

Now – this book seems pretty affordable (at $10).

But in reality, it has very little actual tips inside.

Most content is an overview of diabetes, which you can find on the internet.

So overall – I don't find it worth the investment.



#1 – How It Works & Producer

Let's talk about the basic info of The Diabetes Code:

  • main contents
  • author of the book
  • methods it promotes
1. How It Works

The Diabetes Code promotes the most natural way to reverse diabetes (according to its claims).

So in order to achieve that, it suggests several methods:

  • low-carbohydrate diet
  • obesity control
  • intermittent fasting

Now, I already said that intermittent fasting is not safe in a lot of cases.

So I wouldn't recommend it to diabetic people.

Also – at the start of the book, it claims to agree with alternative science.

This probably means not sticking to medical devices, surgeries and drugs.

Honestly – I don't agree with that approach.

That's simply because people suffering from diabetes need prescription drugs.

I definitely avoid supplements and courses that criticize prescription treatments.

If you're a diabetic, taking your prescription drugs is a must.

Not to mention that a book can't really reverse diabetes.

2. Producer

Now – The Diabetes Code is written by Dr. Jason Fung.

After a careful research, here's what I found out about him:

  • Canadian nephrologist
  • expert on intermittent fasting and low carb diet
  • wrote several books about health

If you ask me, he's quite popular when it comes to giving health tips.

That especially for people with type 2 diabetes.

Also – he's pretty credible, due to his medical background.

But then again, I don't really agree with his recommendations in this book.

So even though he looks trustworthy, I'm not a fan of his program.


#2 – Course Content (6 out of 10)

In my view, The Diabetes Code has some decent contents:

  • 15 chapters divided into 5 parts
  • a total of 288 pages
  • contains 2 sample week meal plans

However – as I said, it rather focuses on discussing diabetes.

The part where it gives some actual tips is pretty short, which I personally don't really like.

So if you're curious, let's discuss its 3 most important chapters.

1. Chapter 2

This chapter talks about “the differences between type 1 and type 2 diabetes.”

If you ask me, these 2 cases are pretty different.

As I said – this chapter focuses more on their general facts:

  • symptoms of each type
  • why each form appears

Now – this can help you if you're more sure what type you're battling with.

But honestly, that's pretty much impossible these days.

So I don't consider this chapter extremely useful.

2. Chapter 4

“How not to treat type 2 diabetes” is the title of this fourth chapter.

And here's what it discusses:

  • improper diet/foods
  • activities that can worsen diabetes
  • medications to avoid

Once again, that's some pretty common info.

You can just find it online and read even more than what this book gives out.

However, I don't necessarily agree with all the facts given in this chapter (especially the medication part).

3. Chapter 15

Now – this chapter focuses on “intermittent fasting.”

Again, The Diabetes Code promotes this type of program.

So expect it to teach you how to follow this diet properly.

But as I said – I don't really recommend it to diabetics, since it's still better to have a balanced diet.

Honestly – I don't consider it very effective in losing weight.

Plus, it's not really linked to reversing diabetes.

4. Other Chapters

Here's the rest of this book's contents:

  • How to Reverse and Prevent Type 2 Diabetes: The Quick Start Guide
  • 1 – How Type 2 Diabetes Became an Epidemic
  • 3 – The Whole Body Effect 
  • 5 – The Role of Insulin in Energy Storage
  • 6 – Insulin Resistance: The Overflow Phenomenon
  • 7 – Diabetes, a Disease of Dual Defects
  • 8 – The Fructose-Insulin Resistance Connection
  • 9 – The Metabolic Syndrome Connection
  • 10 – Insulin: Not the Answer for Type 2 Diabetes
  • 11 – Oral Hypoglycemics: Not the Answer
  • 12 – Low-calorie Diets and Exercise: Not the Answer
  • 13 – Lessons from Bariatric Surgery
  • 14 – Carbohydrate-reduced Diets
  • Appendix: Two Sample Week-Long Meal Plans

As you can see, there are quite a lot of chapters.

And if you look closely, there's way more discussion about diabetes (than practical tips).

Plus, there's very little info on the program itself.

Even the meal plans are only given out as samples.

So this course is more of a diabetes facts book (than as a solution).


Overall – The Diabetes Code contains several chapters.

However, there's only a little chapter dedicated to the program itself.

Most of its info is dedicated to general diabetes facts, which is pretty useless.

So I'm not a big fan of its contents.




#3 – Results (7 out of 10)

The Diabetes Code has a lot of customer reviews available.

So you can see a lot of perspectives about how it works.

Note: I only analyzed real reviews, not fake/promotional ones.

1. Positive Opinions

Firstly – let's take a look at the positive feedback about The Diabetes Code.

So here's what previous buyers liked about it:

  1. Most of them said that it helped them reverse their diabetes.
  2. Some mentioned that they lost some weight with the help of this book.
  3. Others also said that it helped them stop their medications.
  4. The rest liked the fact that it was informative.

Now – the overall rating of the book is 4.7/5 stars.

It's a high rating, to be honest, which means a lot of people were satisfied about it.

However – I don't believe that a book can really reverse diabetes. 

Also, it's not safe to stop your prescribed medications after reading the book.

So I definitely don't advise you to follow this recommendation.

2. Negative Opinions

Now – let's see the complaints of people who gave it 1 star:

  1. A lot of them mentioned that intermittent fasting can worsen diabetes.
  2. Others said that the info is repetitive and hard to read.
  3. Some didn't like the fact that it promotes other subscriptions for more details.
  4. There are complaints about the lack of a step by step diet plan/advice.

Again – The Diabetes Code has a lot of discussions about diabetes.

But its original content is very little.

Also – it suggests subscribing to a doctor's program (which costs even more).

So it's not exactly a full course, since you need to pay more to learn everything you want.


Overall – The Diabetes Code received both positive and negative reviews.

A lot of people liked the fact that it's informative.

But there are also user who said that it's not enough.

I'm personally not a fan of it at all, to be honest.


#4 – Side Effects (6 out of 10)

review the diabetes codeThe Diabetes Code didn't receive too many negative comments about its side effects.

But I wouldn't conclude right away that it's safe.

Again – it promotes intermittent fasting.

Usually, an immediate change in diet can have an impact on your body:

  • digestion problems
  • nausea/headache

This tends to happen whenever a person tries this diet out of a sudden.

Now, these issues don't appear in all cases.

But I want you to be aware of what to expect.

Also, intermittent fasting is not excellent for people taking prescription drugs.

So I don't really recommend it, since it's not suitable for a lot of people.


#5 – Price (7 out of 10)

If you ask me, The Diabetes Code is slightly pricey.

That especially if you consider its low content.

1. The Exact Price

Let's first discuss the price listed on Amazon:

  • Softcopy costs $9.99
  • Paperback is $14.99
  • Spiral bound costs $37.95
  • MP3 CD costs $18.99
  • Audiobook is free with an app
  • Free delivery on some dates

Now – The Diabetes Code surely has a lot of content.

But as I kept saying, it's mostly general stuff on diabetes.

There's very little given out about the program implementation.

It's not a scam, but I don't think it's worth the investment.

Also – you're paying for an intermittent fasting program.

But that's not a diet that suits diabetic people too much.

So even though this course seems pretty cheap, I don't consider its value very high.

2. Competitors’ Price

I will introduce to you my #1 recommended book for diabetes.

I'm talking about Diabetes Masterclass:

  1. Diabetes Masterclass has 3 phases that focus on improving diabetes.
  2. It implements 6-part video courses and offers a bonus of 4 diabetes e-books.
  3. The Diabetes Code has 15 chapters that are divided into 5 sections.
  4. It contains more info about diabetes in general (than solutions).
  5. Diabetes Masterclass offers lifetime access to the course, for only $19.97.
  6. The Diabetes Code's lowest pricing is $9.99, for the softcopy.

Between these two books, I consider Diabetes Masterclass as the best option.

It provides more specific lessons that can really improve your diabetes.

Also – I suggest combining it with a supplement like Gluco Cleanse Tea.

When used together, these 2 products make one of the best treatments for diabetes.

As for The Diabetes Code, it's not too close to Diabetes Masterclass.


Overall – The Diabetes Code is slightly pricey for its content.

It could have been better if it focused more on solutions for diabetes.

Unlike other books, it's not the best value for your money.

So if I were you, I would go for another alternative.




#6 – Final Conclusion

Here are my summarized points about The Diabetes Code.

1. Decent Content

Now – here's the structure of The Diabetes Code:

  • 5 sections with 15 chapters
  • sample meal plan for 2 weeks

There are more sections that focus on facts about diabetes.

Still, very few pages are dedicated to the program and solutions.

So I would consider that insufficient.

2. Program Doesn't Fit All

Again – The Diabetes Code is based on intermittent fasting.

That's why it's not very safe for everyone.

Instead of reversing diabetes, it can worsen the condition.

Also – some healthcare professionals don't recommend this diet.

3. Slightly Pricey

In my opinion, The Diabetes Code is not the best deal out there.

The softcopy version costs $9.99.

But if you consider the “solutions” you get, it's not too much worth it.

Even the recipes that it offers are only samples (they aren't complete).

So I couldn't say that it's a good investment.



My Verdict – Worth Or Not?

review the diabetes codeShort answer: Not really – it comes with some disadvantages:

  1. Based on intermittent fasting 
  2. Pretty pricey for its content
  3. Its recommendations can be dangerous

Honestly – The Diabetes Code is pretty good at explaining diabetes.

But it doesn't really focus on implementing a solution.

Also – intermittent fasting can be dangerous, in some cases.

So I really can't recommend it to you.

Instead, try the best diabetes program I know.

I'm talking about a book called Diabetes Masterclass:

  • Recommends some original methods
  • Very effective in improving diabetes
  • A lot of customers recommend it
  • Offers more materials at an affordable price

In fact, Diabetes Masterclass comes with a full course.

It really provides a lot of teachings and materials.

Also – it's more specific to the program it recommends.

Besides, I suggest you to combine it with an oral supplement (like Gluco Cleanse Tea).

It's an internal product with a much stronger effect on high blood sugar.

With these 2 products together, you have some much higher chances to get some real results.
