Why We Get Sick: The Hidden Epidemic at the Root of Most Chronic Disease―and How to Fight It

Rate this book
A scientist reveals the groundbreaking evidence linking many major diseases, including cancer, diabetes, and Alzheimer's disease, to a common root cause—insulin resistance—and shares an easy, effective plan to reverse and prevent it. We are sick. Around the world, we struggle with diseases that were once considered rare. Cancer, heart disease, Alzheimer's disease, and diabetes affect millions each year; many people are also struggling with hypertension, weight gain, fatty liver, dementia, low testosterone, menstrual irregularities and infertility, and more. We treat the symptoms, not realizing that all of these diseases and disorders have something in common.  Each of them is caused or made worse by a condition known as insulin resistance. And you might have it. Odds are you do—over half of all adults in the United States are insulin resistant, with most other countries either worse or not far behind.  In Why We Get Sick, internationally renowned scientist and pathophysiology professor Benjamin Bikman explores why insulin resistance has become so prevalent and why it matters. Unless we recognize it and take steps to reverse the trend, major chronic diseases will be even more widespread. But reversing insulin resistance is possible, and Bikman offers an evidence-based plan to stop and prevent it, with helpful food lists, meal suggestions, easy exercise principles, and more. Full of surprising research and practical advice, Why We Get Sick will help you to take control of your health.

The first important thing to note is that Ben Bikman based his book on a lot of reliable research and studies - not on his own whims and fancies. The second thing is that he is not trying to sell you any supplements or expensive consultation programmes. You can also be fairly sure that he’s not being funded by any of the big industries. What’s more - he is an expert on insulin resistance, being a biomedical professor who had earlier on stumbled upon the fact that insulin seems to be the one common factor in almost every chronic disease that we are facing today.

I am convinced that this book has the potential to change the health and lives of countless people if they would just follow the simple suggestions that he has towards the end of the book,

Why we get sick is immensely well-written and easy to understand. I hope every doctor or doctor-to-be would read it so that they can make real improvements in the health outcomes of their patients instead of endlessly supplying medications that often do not ultimately have a positive impact. Everyone who experience chronic illnesses or want to prevent them should also pick up this life-saving book.

Highly recommended.

Thank you NetGalley and Benbella for the ARC. This is my honest review.

Summary:
The author provides a robust explanation of insulin resistance and how it impacts our health in various ways as you would expect from a researcher in this field. The information paints a morbid picture of many of our leading killers and how they are connected to insulin resistance. There's interesting information on genetics, hormones and reproductive health, but things get weird when you get to the lifestyle area. The author moves into a strange place of kind of pushing keto, but not really. Re-framing it to be low carb. They talk about how eating whole fruits is good for us and has little effect on blood sugar/insulin resistance since the fructose is bound in fibre, but later refers to a glycemic load table that discourages the consumption of bananas, berries and citrus. This raised serious alarm bells for me and as the book went on and more and more information was shared about keto I lost all interest and trust in the author. This jaded the first half of the book for me too.

Seriously, referring to the same table on glycemic load, the author recommends 'being careful' in consuming lentils and beans. I've seen a study showing how people eat more beans have lower rates of all cause mortality. Similarly, there's studies showing how consumption of foods rich in antioxidants, such as berries, level out our blood sugars. Really, anyone suggesting we cut carbs and avoid some of the scientifically proven healthiest foods on the planet (whole fruits and vegetables) just seems irresponsible to me. Eat your fruits and vegetables and don't do keto. Seriously, it may have some use as a treatment for epilepsy, but you'd need to way that benefit up with your increased risk of heart disease and other illnesses.

I wouldn't really recommend this book to anyone. Maybe someone with insulin resistance or a chronic metabolic disease could get something out of it. However, I think there are more informative, accurate and effective books addressing these illnesses through lifestyle choices and would recommend those instead. For example, How Not to Die: Discover the Foods Scientifically Proven to Prevent and Reverse Disease and Prevent and Reverse Heart Disease: The Revolutionary, Scientifically Proven, Nutrition-Based Cure.

The main message I took from this book is that insulin resistance is incredibly prevalent in society and underpins our leading causes of illness and death.

Some notable points:
- In the 1900s if you asked why we got sick, the answer would be infectious diseases. This is no longer the case and we now get sick from chronic metabolic diseases often underpinned by insulin resistance.

- A recent study suggests that as many as 85% of American adults are insulin resistance. Many other countries have similar or worse rates of insulin resistance.

- We are sick. Worldwide, we are struggling with diseases that were once very rare. Each year, roughly 10 million people die from cancer and almost 20 million people die from heart disease. About 50 million people have Alzheimer's disease and almost a half a billion people have diabetes. Roughly 40% of adults worldwide are considered overweight or obese.

- Not all adaptations are beneficial.

- Insulin resistance doesn't kill you, but it is a vehicle that takes you closer to death.

- Prolonged insulin resistance physically alters the brain. 10 years of insulin resistance ages your brain by two years compared to someone not insulin resistant.

- Insulin, independent of body fat, directly inhibits testosterone.

- The average onset of puberty was around 16 years for girls in the 1800s, 14 in the 1900s, then 13 and 12 in the mid and late 1900s. Now the average is under 10 years old. This is connected to obesity and other health issues.

- Having people with type 2 diabetes take insulin creates an artificially high state of insulin, higher than the pancreas could ever produce. However since insulin increases insulin resistance, a vicious cycle forms where more and more insulin is needed.

- Obesity is also an inflammatory disorder. It is a state of chronic inflammation.

- Tobacco smoke increases insulin resistance in those exposed to it, even through second hand smoke.

- One week of less sleep can make the body 30% more insulin resistance when compared to normal sleep patterns.

- Exercise helps increase insulin sensitivity.

- Glycemic load is a better measure of how much potential glucose is in your diet than glycemic index.

Insulin was long regarded as the hormone only diabetics should care about - this book takes a more holistic approach of insulin's effect on the brain, the muscles and the cells in general.

It's a very technical and very theoretical book - recommendations and "solutions" are only at the very end. It presents the problem in great detail before attempting to give advice.

I loved the explanations of why muscle mass is not only an aesthetics consideration (it regulates glucose metabolism without insulin involvement), the practical difference between aerobic cardio vs anaerobic resistance training (the latter is better, but only if you're willing to do it), the timing of meals regarding hormone levels (fast for longer periods for the body to rest and become insulin sensitive again) and the effect of synchronous macro digestions to mimic real food ratios (fats + protein are often found together, but rarely contain high carb levels as well).

He mentions the effects of salt (some people are sensitive, other can consume it freely), that carbs shouldn't be drunk (since the fibers are usually missing, which would dampen the insulin spike) and that blood pressure should go down once insulin levels are in order.

Good general introduction to nutrition, based on evolution and latest researches, ignoring the poor confusing studies done over the past decades that caused all this havoc.

Bikman writes about an important topic: insulin resistance (IR). Everyone should become familiar with this topic, and I learned a lot from this book.

Bikman is a good writer. He presents things in an organized way that flows easily. Relevance and connections are made with the appropriate amount of cross referencing and repetition when needed. I found the book easy to read, even though the topic is potentially quite dry.

The author should be heavily criticized for hyping the topic beyond what is reasonable. He sets out to establish that this is the single most important health issue ever. He repeatedly claims that 85% of Americans have this problem. Well, it turns out that this is a cherry picked statistic from one study done in Latin America. The real figure is 25% to 33% according to main research institutions best estimates. That is still very significant, but Bikman is taken on occasion to select only the most supportive studies and findings, and does not present a balanced and accepted view. Is he claiming that there is a conspiracy trying to hide this disease? Not directly, but he uses persuasive language that might easily support a conspiracy theory.

He spends the entire first half of the book making the claim that ALL modern diseases are caused by insulin resistance. Hypertension (high blood pressure) is caused by insulin resistance. Well, I checked some of the references. He makes this particular statement on page 14 without a reference, and the first cited reference on that does not actually contain the subject of the sentence that contains the citation. My research pointed out many papers covering that hypertension and IR tend to occur together, but there is no consensus on whether one causes the other. They both could simply be the result of poor diet and lack of exercise. In fact IR is correlated with many diseases that are associated with being overweight and out of shape. He boldly however insists that all hypertension is caused by insulin resistance, implying unrealistically that if IR was solved, there would be no more hypertension.

He presents many other diseases are caused by IR. Cancer? Well, he does not say that cancer is caused by IR, but he does say that cancer with IR is worse than cancer without IR. Well, yes, of course, cancer with ANY disease is worse than cancer without that disease. Duh!

How about heart disease? He lists a number of factors that correlate to heart disease, and IR is mentioned several times. The significance of this correlation is never reported. Then, on page 23 he simply jumps to stating "I hope it is clear . . . no single variable is more relevant to heard disease than IR." This actually was never shown, nor was there any research cited to support this, he is instead appealing the intuition of the reader based simply on the number of times he has mentioned IR. This is a logical fallacy.

If your IR gets bad enough, we call it diabetes. In fact IR has been called (or heavily overlaps with) pre-diabetes. Some of the figures he uses includes both IR and diabetes, or blurs the distinction, giving once again inflated figures for the non-diabetic IR.

Once you get past the heavy self-promotion of his subject, he moves on to a decent description of the disease itself, why it exists, and what to do about it. This is all quite science and evidence based, and I learned a lot. This is where the real value of the book lies.

He explains how insulin is a hormone that does a lot of things. One thing is to turn sugar into fat, which is the primary effect, but it is important to remember that there are other things it does: like promote cell growth. If you have a lot of sugar going though your blood, you need a lot more insulin. But once you have a lot of fat, those cells stop taking in more fat. Insulin stops working as well. Hence, insulin resistance. So the pancreas creates more of it, causing more of the other things that insulin does happen as a side effect.

His recommendation is sound as well. Watch your diet, avoid piling on the carbs, and get exercise. Again, this fully rational and supported by science.

Overall, this is a book that I learned from, but I can't say it is in excellent book because of the way he cherry picks evidence in order to promote this as the one main cause of all disease, and the associated implication that if we could solve IR, we would thereby solve all disease. This is a simplistic reductionist theory akin to a fad believed to the exclusion of other theories. Sorry, Bikman, it is just not that simple. There are 70,000 proteins floating around in humans, and the complex interactions have still be mapped out. Insulin resistance is an important problem that we need to be aware of, but it is not the cure-all for all disease.

I read this book about insulin resistance last summer; I revisited it this week to harvest quotes and main points for my journal. I ended up reading each page again. Ben Bikman is right up there with Dr. Jason Fung as one of my favorites. I will listen to *any* podcast that the winsome Dr. Bikman is on. Curt and I have watched videos on YouTube, which I highly recommend.

Insulin Resistance. The anabolic hormone that has an affect on every cell. Almost every major disease can be traced back to insulin resistance. Maybe not stuttering and hang nails. But heart, cancer, diabetes, migraines, PCOS, ED, psoriasis, fatty liver, tinnitus, Alzheimer's, Parkinson's... you get the idea.

How to lower insulin? Lower stress, get good sleep, ditch processed food, eat less carbs, exercise, and practice some form of time-restricted eating. I appreciate his emphasis on exercise. It may not be that effective for weight loss ("You can't outrun a poor diet" people love to repeat), but movement and contracting muscles are necessary for health. From a video: if you don't have any weight-lifting equipment, start by standing up and sitting down repeatedly.

Dr. Bikman is a (double) Ph.D., not a clinician, but he recommends getting fasting insulin numbers in addition to fasting blood glucose. I've always been nervous about being that "strange" patient, but I'm going to ask for fasting insulin draw at my next doctor's appointment.

One of the best non-fiction books I have ever read. It is mind-bogglingly eye opening and could change the life of anyone who reads it. I write this as I go to read it for the second time a mere two months later because it is so good.

As a medical professional, I feel this is an important work and have recommended to my colleagues.

Although there is (somewhat unavoidable) repetition, I am happy to overlook this for the expansive, insightful and practical coverage of such a crucial topic.

I must admit to feeling somewhat frustrated to read reviews that attempt to pigeonhole the text as ‘just another keto book’ and trot out ‘blue zones’ to discredit the themes being addressed. Unfortunately, this belies an ignorance of scientific method and the very reasons we have reached this point as a society due to misinterpretation and/or misrepresentation of epidemiological data.

I can't believe I've read this 3 times. I've learned something different each time. Still 4 stars.

***************************************

I read this one a while ago and I have since binge watched this author on most of the podcasts he was a guest on. I think I like him more now, as well as his message. I'm not a fan of keto but that is because I don't do well on that type of diet but I loved the breakdown of being insulin resistant. Definitely educational. So I've added a star...it's now at 4.

****************************************

This is Nonfiction/Health. The author shows how being insulin resistance is the root of many diseases even if you are not diabetic. He also mentions how determining insulin levels more accurately gages the quality of health than glucose levels are. Then this author eventually gets around to how a Keto Diet can benefit such problematic health situations.

I liked the information but I'm always left with the feeling (when reading books like this) of all that there is yet to be discovered and how little the medical community actually knows. I love though that huge strides are being made in this area as more and more studies are being done.

The keto books cite all the studies and sources on why this type of diet is the best. Then there are those that promote the plant based diet that do the same. Then there are the IF diets, and on and on.

This one wasn't quite 3 stars, but I rounded up.

This book was fascinating, as I hadn't realized insulin resistance could have such an impact on the health of people. The author focused his point on peer-reviewed research and his own experience as a leading expert in his field. This read well, as it didn't feel like I was reading a medical journal and the message the author was writing about is one people need to know more about.

Not what I was expecting, but incredibly fascinating. I was expecting to learn about germs and viruses and how they get into the body, but instead learned all about insulin! This books used many credible research studies to show the relationship between your bodies ability to use insulin (either being resistant or sensitive to it) and MANY common illnesses and diseases.

Very eye opening book for me. I personally tap dance right on the edge of being classified as diabetic, so this really woke me up to the issue of insulin, weight, and body metabolism and the impacts they all have on your health. (I knew, just didn’t want to address).

The author does a good job walking you through the chemical reactions, effects on the body, impacting fat, impacting metabolism, impacting health.

I thought maybe it got a little too technical, but I thought it was needed AND I was listening to the audiobook while walking, I think some of this would have been better with his charts and indexes.

I did learn a bit. Less fruit juice (I was juicing), less diet drinks (I thought that was a win for me, but nope). More dairy fat. Obviously less carbs (I count calories). On working out, more resistance training than aerobics, but like he said do something that YOU WILL DO! (I walk).

Overall a good book. Really got me focused on my health and the impacts of bad choices.

This book makes a strong case for altering your lifestyle (diet and exercise) in order to avoid insulin resistance/regain insulin sensitivity. It was a good reminder of a lot of the things I learned by reading The Obesity Code by Dr. Jason Fung. Main takeaways: Most American adults, and many children, are insulin resistant (and obese and sick because of it.) Our diet is the cause. Good news: Insulin resistance is entirely reversible (unless you have Type 1 Diabetes) through diet and exercise. Bad news: It takes planning and willpower. We need to restrict our carbohydrates, increase our "good" fats and protein, limit our food intake to a window of 6-8 hours so we're not grazing all day, fast for longer periods of time frequently, get adequate sleep, and exercise to the point of muscle fatigue at least 5 days a week. That's ALL! Ha.

Preface to the review: I listened to the audio while I was deep cleaning my house... At 1.5 speed. So. I might have missed a few things. (I'm not going to do that with non-fiction anymore.)

This is a very hype refocused book. The author's concern is insulin resistance and how it affects the various systems of the body. He considers what the data shows as far as how insulin resistance is connected to a variety of conditions and diseases, and how you can treat insulin resistance with lifestyle changes.

I think this is an important issue that needs to be more commonplace in all discussion of illness and disease. Every doctor should check their patient's insulin and glucose levels from the very beginning. Every patient needs to know about the importance of carb reduction in treating whatever ongoing complaints they may have. This book is a great resource that is a good first step in learning about insulin and the many ways it affects every body system.

I want to get a hard copy so I can see all the lists and references that were mentioned on the audio. I feel like it will be a valuable resource.

My one caveat here is that it is definitely focused on one issue only. There's hardly any discussion about other factors that play into all these illnesses. The book maybe should have better title that more clearly indicates that its strictly about insulin and insulin resistance.

This book provides a boatload of really good reasons to change my wicked ways (especially with carbs and sugars) and make better decisions to improve my health. It is packed with information, and the research to back it! Bikman gives published studies for every claim he makes —with over 35 pages of references (in small print!) at the end of the book. I come from a family of diabetics and I KNOW how much better I feel when I take steps to discourage insulin resistance. But sometimes I am weak and I allow the social factors surrounding food as well as the pleasure of eating high-carb to lead me into a downward spiral of cravings and bad food choices. The consequences include inflammation and pain, sleep issues, feeling less sharp mentally, increased anxiety, and stomach issues. “Why We Get Sick” is a good kick in the pants to remind me WHY the long-term health benefits of avoiding carb-heavy foods far outweigh the momentary pleasure of indulging in them.

This book should be read slowly to understand the medical terms and how the body functions. Some simple steps to fight insulin resistance are reducing sweet drinks (including fruit juices and diet sodas), doing resistance training (exercises using weights), reducing carbohydrates, eating more vegetables, and eating meals about five hours apart (no constant snacking).

Nothing new. Just an author who got tired of writing review papers and instead made a book out of it instead, with the same old diet/exercise stuff at the end; even the author knew that his work was a replica of this "new generation of health/science books".

This is one of those books where everything the author says might very well be true, but the way it's presented makes me skeptical. You know, very much "here's proof these other things are bad and dumb, but this one diet is great! Works for everyone! Do it now!" He's definitely trying to sell you an idea. There's no section of precautions for a low carb high fat diet, which I know isn't safe for everyone, especially if you make the change very suddenly. I never trust anything that's presented as all sunshine and rainbows.

That being said, this book is much better than other "low carb diet" books. It doesn't feel super slimy.

This is one of those situations where I'm not going to go through and check the references because I just downloaded the audiobook to have something to do for five hours. But if a low carb diet book is what you're looking for this one is probably the best one I've read? The author sounds like a reasonable person and he doesn't say anything super outrageous. He's basically saying what we all already know: refined carbs are bad. Don't eat them.
January 24, 2024
Very informative read that condenses a huge amount of studies and research into easily digestible sections. Definitely becomes repetitive, which is a good thing really because the facts and ideas are constantly being backed up by real science, however this can easily lead to disengagement with the text. A good one to pair with Lifespan, which follows a similar trajectory for why we get sick/don’t live as long as we could and offers some similar tactics to combat our destructive lifestyles, tactics that really aren’t unreasonable for most!

3.5 stars. Good book on insulin, insulin resistance and why it matters so much.

Yet, I don't agree with some of his conclusions and food recommendations, pushing keto a bit too much vs what is known in the scientific literature, up to a point where he suggests that mayonnaise might be good for you.

I took pathophysiology by Dr. Bikman a couple years ago and learned so much! A lot of this was review and I wonder how well I’d have understood if I didn’t already have some of this knowledge. All in all, I think it’s cool to feel like we have control over our own health and a lot of diseases in America. I feel more motivated to prioritize my health and do what I can to extend my healthy, happy years of life.

Benjamin Bikman makes a convincing case about insulin resistance and the need to be aware of the long term health effects.

Very-research driven, and focused on insulin.

He also presented at a forum about this topic and is a great way to get a 30 minute summary.

Several years ago my then-boyfriend told me about a group of scientists who were calling Alzheimer's "Type 3 Diabetes." And I was fascinated. Especially because I had been diagnosed as pre-diabetic several years earlier and was managing it via diet so well that, when I switched doctors, the new one didn't believe me (I've fallen off the wagon several times. Nobody's perfect. And my rant about mindful eating can go on a different review).

I'm not sure where I heard about this book but I thought it might be interesting, given my history.

It's not a bad book. In fact, it's quite a good one. The section on gallbladder blew my mind. And I appreciated his take on fasting--- so many people say it's the answer to everything I appreciated his moderated opinion. But, if you follow him on social media(which he does REALLY well), there's not that much that is new. So pick one or the other. And get empowered.
