This is a guest post from Dr Joel Fuhrman MD.
Most people never experience the healthy sensation of feeling hungry. Most of us keep eating to avoid hunger! But actually, feeling hungry is healthy. It directs your body to consume the amount of calories it requires for optimal health and ideal bodyweight.
Hunger, in the true sense of the word, indicates to us that it is time to eat again.
Instead of TRUE hunger, people experience TOXIC hunger–detoxification or withdrawal symptoms that they mistakenly consider hunger. What is Toxic Hunger?
Toxic hunger is the group of symptoms a person experiences as our body mobilizes toxic wastes for elimination.
When our diet is low in nutrients, we build up intra-cellular waste products. So when digestion stops, our body goes through a period of “cleaning.” Meaning our tissues release toxic substances into circulation for removal. Our cells can harbor toxic products that will eventually make us sick.
These uncomfortable “detox symptoms” occur after a meal is digested and the digestive track is empty. We start to feel shaky, head-achy, weak, get abdominal cramps or spasms, which we believe are hunger symptoms because they are relieved by eating.
What is Real Hunger?
Consider that real hunger is not often experienced in our modern, overfed population. Most people no longer even remember or are aware what hunger even feels like. Most people are surprised to find that true hunger is felt in the throat and not in the head or stomach. Removing toxic hunger and getting back in touch with true hunger makes eating more pleasurable and we are able to maintain our ideal weight without dieting.
Continually eating to alleviate these withdrawal symptoms is one of the most important contributors to our population’s overweight condition. We eat the wrong foods and just a few hours later we feel ill and we are driven to eat again to relieve the discomfort–typically the wrong foods again.
An Alternative to Hunger
Now, you do not want to go hungry and deny yourself food to achieve an ideal weight. However, there is another answer. When we eat a high nutrient diet, rich in colorful vegetables and fruits, you will better meet the nutrient needs of our body–thus reducing or eliminating the withdrawal symptoms, that I call toxic hunger.
These super foods eliminate toxic hunger and overeating:
• Berries: blackberries, strawberries, blueberries
• Seeds: flax, sesame, sunflower
• Green Leafy Vegetables: kale, bok choy, spinach
• Colorful Raw Foods: tomatoes, carrots, peppers
• Steamed Greens: broccoli, string beans, asparagus
High-nutrient eating enables us to deal better with all types of stress, but in the case of hunger. Eating more high-nutrient foods will enable you to avoid “stress hunger” and not have the cravings and drive to overeat.

i am iron deficient (anemic)does dr furhman’s diet include iron rich foods (besides spinach)? (i already had gi testing done, all is normal)
Wow, Dr. Barry Sears (author of the Zone Diet) was right when he said that few things create as visceral a response as religion, politics, and nutrition.
One thing that is frustrating in the world of nutrition is that people are so dynamic and our environment is so dynamic that it is sometimes hard to generalize laboratory research to the general population.
Another thing that has always been frustrating to me is that so many doctors are fighting with each other about the best approach to everything.
This leaves the consumers wondering which doctor to believe.
By arguing doctors may think they are helping consumers, but in fact they are distracting and confusing consumers.
I am an open-minded and analytical person, and I know for a fact that there are more than 100 ways to skin a cat. And I believe that people can say the opposite things and both be right. Our bodies are so amazing that it I believe it is capable of multiple realities.
One thing I don’t think anyone can refute is that Dr. Fuhrman cares about the health of people and has actually helped thousands of people.
So why be mad at someone who is devoting his life to helping people regardless of him methods.
I feel bad that Dr. Fuhman has to defend his practice to an internet blog community when he could be helping more people.
I wonder if any of the people spewing venom have actually ever helped anyone improve their health.
Well I did find ONE thing I agreed with in this article – and that’s that most of us don’t get to a point of feeling hunger. As for in the throat???? And the idea of toxic hunger – well let’s just say It would be interesting to see evidence of this….
Carbs, protein, fat… it all has to be balanced. You can not eliminate any one of them for lasting results. Take those high protein low carb diets. People were getting quick results with dangerous future side affects! Not only should you not eliminate any of the food groups, you need to mix & match them. You really can eat a large variety of foods when matched up correctly for balance. Even vegetarians (the ones doing it right) get their protein from alternative foods.
The comparison to religion I made should have been to over zealous religious people or a cult like mentality. If you want to see just how zealous the Nutritarians are just bring up Weston A. Price; you’ll also get to see how open minded they are about different ideas.
I don’t debate that his diet would work; like I’ve said any lower calorie plan would do that.Eating more nutritious foods is always good ,but you can find lists all over the internet for so called super foods so this isn’t a knew idea. I was trying to make a point about stating opinion is fact and posting an article that to me was clearly there as an advertisement for his books and website.
Huh. I have fasting hypoglycemia. (Not reactive)
And I’ve fainted numerous times from it, blacked out others.
I don’t think that’s normal.
My impression is that Campbell is rather careful about not claiming too much based on the data presented. Nevertheless, the data is astounding! And Dr. Fuhrman brings added clarity to the subject with his concept of “nutrition density”–as we eat more of the healthful foods, we naturally eat less junk. And while it may be too complex to pin down the precise causal relationships, the general correlations are clear. Moreover, I don’t think anyone is arguing that saturated fats and transfats and refined carbohydrates are not a problem. The question is how much is “safe”–how many cigarettes can you safely smoke? And based on the data, the safety of animal protein is also rightly called into question. BTW, the complexity of these issues is discussed by Dr. Furhman, among other places, in his analysis of the Mediterranean Diet (ETL p.39-45). Olive oil, he says, is a bit less unhealthy than many other kinds of extracted oils, but the real key to the traditional Mediterranean diet was the prevalence of fruits and vegetables, the agrarian lifestyle (lots of open air exercise), and relatively low meat consumption. With the change in lifestyle and diet, the continued use of olive oil has not prevented the advent of (the aforementioned) “diseases of affluence”…
Your worried about acrylamide ;the stuff has been around since man used fire/heat to cook, and has only been shown to theoretically increase cancer rates in rats. If your worried about every little negative thing said about food then you’ll be left with nothing to eat.
Sorry – I do have to add though that this si still not cause and effect. Campbell cannot say for sure whether health boons are due to the increase in fruits/veg/whole grains or the decrease in meat/dairy or both. THere are too many confounding factors to make such untenable statements.
To be clear, I am not against vegetarianism nor am I against higher fat diets. You can eat healthfully and poorly within the context of both.
I understand that some interventions work clinically and take a while to become published but understand that this theory is being presented as fact. I’m all for new ideas and proposals but I prefer they go through the ringer of scientific scrutiny.
Appreciate the dialogue!
I see where you are coming from as I have not read ETL. I will check it out when I have some time. I think we agree on more than we may think
Increasing fruit/veggie/whole grain consumption is a healthful thing to do.
Wow, there are a lot of different opinions about this subject. In my experience, I do think that our society is overfed and undernourished. You can be obese and still be malnourished if your diet consists of things like chips and donuts or whatever. I noticed that once I started eating lots of whole, unprocessed foods, I wasn’t feeling as “hungry”…I actually just felt satisfied between meals and I wasn’t tempted to snack so much.
As far as “hypoglycemia” goes, most people who claim that they have it are actually just experiencing the effects of glucagon, the hormone that pulls stored fat out of your body and converts it to glucose for your brain/body to use as fuel. True hypoglycemia usually only occurs if your pancreas doesn’t produce glucagon or if your body is somehow resistant to it. And I’m also pretty sure most Americans don’t ever let themselves get truly “hungry”; most of us eat pretty often…if you have ever fasted, you’ll attest to the fact that the hunger you feel after that is definitely a lot stronger than any hunger you normally feel on a daily basis.
Actually I, and Dr. Campbell– and expecially Dr. Fuhrman –would agree that it is the over-consumption of meat and dairy, etc., and the under-consumption of fruits and vegetables and whole grains. Dr. Campbell says the benefits of lowering meat & dairy consumtion seem to continue as we continue to reduce them as a percentage of our diet. Dr. Fuhrman emphasises reducing them (as opposed to eleminating them) and especially emphasises the consumption of green vegetables. Neither book– “The China Study” or “Eat to Live” –suggest that one must become a vegetarian to eat healthfully. It’s always a matter of degree and each individual can tweek the general approach to meet their specific physiological and psychological needs. For example, since I am very thin and tend to be rather active, I am eating more nuts and seeds and avocados. Someone who is trying to loose weight would want to eat less of those things.
Hi Merry,
The poster actually said that there were hundreds OR thousands of references, so I think she wasn’t really sure exactly how many, but knew it was extensive. I just did a quick check and counted 360 footnotes in the Eat to Live book, and most of the footnotes cite multiple journal references to back up the points he is making, so my rough estimate would be that there might be around 1000 in this one book (I’m not going to try to count them all). Dr. Fuhrman has written a number of books, so when he commented that his books contain thousands of references, that was likely an accurate assessment.
I’m sure you are right that most of the references are not going to be related to what he says about toxic hunger, since hunger is only one of many topics that are covered in the book, however, the reason the ETL book has been referred to by so many people on this thread is because they feel that they were able to overcome their toxic hunger by following the dietary recommendations found in the book. I actually haven’t read ETL in a number of years, so I’m not really sure how extensively the subject of toxic hunger was covered there, however, I do know that the ‘Greatest Diet on Earth II’ DVD definitely does have a major focus on the subject.
I am a 55 year-old whose life has been changed profoundly for the
better by Dr. Fuhrman’s Eat to Live program. I have been following Eat to Live for close to 4 years.
Arguments on the concept of “toxic hunger” deflect attention
from critically important aspects of Eat to Live. I fear that
negative posts may keep people from checking out a program that
just might be the best thing that ever happened to them. It certainly
has been for me.
I love the way I look, I love my energy level, and I love how easy it
will be for me to stay the same weight for the rest of my life. As
someone who had struggled for decades with yo-yo dieting, that is like
a dream come true.
Please, if you are someone with a weight problem or a health problem,
take time to read and consider:
1. Dr. Fuhrman’s main point is that we should eat the most of foods
that are highest in nutrients, and the least of high-calorie junk
foods. That recommendation fails to set off my “this guy might be a
quack” alarm.
2. I almost can’t believe it myself:
here I am, by far the happiest I have ever been in my life, eating
nothing but vegetables, fruits, beans, nuts & seeds, with various
flavor enhancers (vinegars, spices, soy milk, dried fruits, etc.)
Hey, if I’d been told that, I would have cried.
I now absolutely LOVE these foods. It is partly that I have learned great recipes,
and partly that our tastes in food can change very dramatically.
No, I never would have believed it. You just have to try it.
3. I am convinced that eating foods high in nutrients satisfies our
hunger. I am a highly experienced dieter, and I have never been this comfortable in my life.
I’m convinced that cravings are our cells crying out to us that they need nutrients.
I did several years of Dr. Ornish’s and Dr. McDougall’s programs
before starting Dr. Fuhrman’s, and I find Dr. Fuhrman’s to be
the best of a good lot. The Eat to Live foods make me feel pampered,
and I am not hungry between meals. My health and energy levels have
been the best on Eat to Live.
4. I have not even touched on the disease-reversal that can be
accomplished with Eat to Live, and the programs of Drs. Ornish and
McDougall (and others). I think that for a number of scientific
reasons, Dr. Fuhrman’s program is the most powerfully effective
reverser of disease, but even if you don’t believe that, you’ll be
MUCH better off with Dr. Furhman, Ornish, McDougall, or Esselstyn than
with the American Heart Association diet, for instance (and that has
been studied), or heaven forbid, the standard American diet.

Don’t be distracted by arguments about toxic hunger!
Eat to Live is a lifesaver.

I just checked out this book from the library. To be specific, there are 28 pages of small-print endnote references to various studies. While they all do not specifically deal with ‘toxic hunger’, the references all seem to back up various points that are made in the book, and most of the references are to studies printed in highly regarded journals.
Saying “hundreds of thousands of references” is vague. It’s good to be specific when you’re trying to prove a point.
I cannot point you to any more external sources at this time. It is a relatively new concept and still needs more money for general acceptance (studies). All I can say is that the proof is in the belly and Fuhrman’s writings
Cheers,
Elijah
Good day Mike,
I enjoy your healthy discussions and open-mindedness!
I don’t think we will see any studies on this for a while, gotta have some big money for good studies and toxic-hunger is definitely not worthy of drug company sponsors.
In the meantime, thousands of bellies are pain free!
Cheers,
Elijah
Fuhrman has many hours of free information on his website! I spent a week reading his website before it finally convinced me to join the online member center! I love the member center so much that I have been a member ever since August of 05′. Its odd how some people will pay $100/month or even $20/month for media delivery via tv/internet but not pay $8/month for their health! We only get one body, our vehicle to experience life to it’s fullest.
I am not trying to get anyone to join the member center though. Just trying to express that I was a bit of a skeptic at first so I went to his website and just kept reading and reading and reading for quite some time to get a general idea of his thoughts! I think it is the best bargain on EARTH right now! I often think that it should cost $100 month after having used it extensively (Don’t raise the price though Dr. Fuhrman)
Ellie – I guess you could say it is just a theory since toxic hunger has not been in any peer-reviewed scientific journals and I don’t think the studies will be out for quite a while! It has been proven with my belly though
All I can say is that I hope you try it! No more belly pains, shakiness or headaches await us!
Warmly,
Elijah
Hi Cereal,
You are correct that not all Peanut Butter contains hydrogenated oils. David was mistaken about that, however, even the natural brands of peanut butter that contain no hydrogenated oils have the problem of acrylamides which form when the peanuts are roasted. The reason for the suggestion of raw cashew butter or raw almond butter as a healthier alternative is to avoid the acrylamides.
As for the issue of hunger, it is quite clear to me that fake hunger exists, and drives people to overeat and carry extra weight. How do I know this, and why do I consider it more than an unfounded theory? I will tell you. Most of my life I have experienced shakiness, weakness, headaches, and a gnawing, grumbling stomach after a period without food, and since these symptoms were relieved by eating food I slways thought they signified hunger. How then, can I possibly explain the fact that I can now go for much longer periods of time without food, and yet never experience any of these systems? It has been years now since I have experienced any of these symptoms, and at this point I feel like I don’t even know I have a stomach because the only place I ever experience hunger is in my throat. The throat hunger is not uncomfortable, and I don’t have the same fear of becoming hungry that I used to, and I don’t eat prophalactically to avoid the experience. In fact, I know that if I can wait for the experience of the throat sensation to occur, I will enjoy my food a lot more, because I’m truly hungry. I actually find that I am enjoying my food more now than I ever have before in my entire life. What makes me realize that the ‘hunger’ I experienced previously was only fake is the fact that it has completely disappeared, and no longer exists for me. I think this is what the other nutritarians were trying to say as well.
BTW, I really don’t feel that I’m better or superior to other people. On the other hand, I feel extremely lucky to have stumbled across a body of knowledge that most people are not familiar with, and which has transformed my life. Most of my life I have really struggled to keep my weight down, and I have done a lot of yo-yo dieting. What has been different about the nutritarian way of eating is that I have finally been able to make a healthy, permanent, sustainable lifestyle change, while also enjoying my food more than ever. There are many ways to lose weight, but this does not mean that all methods are healthy or sustainable over a long period of time. People sometimes lose weight by taking illegal drugs, but that doesn’t make it advisable or healthy. Dr. Fuhrman’s diet-style has an unrivaled track record in terms of sustainability of weight loss. If you look at his post above, I beleive he referenced a peer-reviewed study in which a group of people eating his diet-style were followed over time, and found to have
achieved greater success with their long term weight loss than has previously been documented before in any study for any other diet. The bottom line is that a surprisingly large number of people who lose weight following Dr. Fuhrman’s diet-style are able to permanently sustain the weight loss without ever regaining it back. The explanation for what makes this possible, is that when people are eating a diet that is very high in micro-nutrients, they become more satisfied with less calories. Conversely, if a person eats a diet that is very low in nutrients, they will feel driven to eat more calories because the body’s nutritional needs have not been met. Of course the other aspect, which was mentioned previously is that people also will overeat in response to false perceptions of hunger.
Although weight loss is a simple proposition of calories in versus calories expended, Dr. Fuhrman tells us that we should not need to ‘count calories’ in order to achieve an ideal weight. He tells us that our body gives us signals that tell us when we need to eat, and when we need to stop, and that eating processed foods will wreak havoc on our ability to be in touch with our bodies natural signals. We should eat when we are hungry, and stop when we are full, and try to avoid eating recreationally, or when bored or not really hungry. If you look at animals in the wild, eating their natural diets, you can’t find any that have become obese from overeating, and they don’t manage this by counting calories. On the other hand, when animals are domesticated, and fed processed food in place of their natural diet, they will overeat and become fat.
On a personal level, I am finally in touch with my body’s natural signals, and this has allowed me to achieve and maintain what I consider to be an ideal weight at which I feel very comfortable and healthy. At the age of 50, I actually now weigh less than I did in high school, which still surprises even me! I am 4’11″ and weigh 90 pounds, and I look and feel healthier and more energetic now than at any time in my life.
I notice you have referred to this diet-style as being like a ‘religion’, and perhaps you have said that because of people making comments about being ‘believers’ in toxic hunger. I just want to point out that they are ‘believers’ because they have had personal experiences which provided them with proof that could not be denied, such that they could not believe otherwise.
Finally, I just want to say that this diet-style is not really an all or nothing thing. There is actually a continuum upon which there is always more room for stepping things up a notch and further perfecting our diet. People can always make changes to their diet which will have a positive health impact, even if they don’t follow everything 100%. Although many of the nutritarians started out by reading the earlier book called ‘Eat to Live’, Dr. Fuhrman’s latest book called ‘Eat for Health’ is actually focussed on how to gradually make healthy lifestyle changes over time, because for a lot of people it is overwhelming to try to make sudden, drastic changes all at once.
In terms of the toxic hunger discussion, I have to tell you that its been awhile since I read Eat to Live, and I don’t remember how much detail about toxic hunger was covered in that book. What I do know is that he talks about it in the ‘Greatest Diet on Earth II’ DVD. So, if you specifically want to hear more about toxic hunger, that is probably a really good lecture to listen to, and its really a great DVD overall. Of course, I own a copy, however, I’m thinking it would probably be available in the library as well.
Very well said David!
Not sure how you could make the argument that vegan activism is irrelevant to one writing a book that recommends shunning meat.
I think Campbell makes some very good cases for different regions and the impact of diet and health on those regions. I also agree that too much processed food leads to chronic disease. I DISAGREE, however with the isoloation of meat and dairy (not extreme excesses therof) in and of themselves as a causational factor in disease.
Very well said, Briana! I concur with your sentiments completely.
If Dr Fuhrman is so keen for his ideas to be out there for free, why aren’t his books on the internet for free, on his website say, as opposed to links to amazon, etc? If I were to take his books out of the library he would be paid, and I would rather not have my actions result in money being paid to a possible quack.
I think the astonishment at people asking for some kind of evidence is hilarious. The response is, you can look at the references in the books but you won’t understand? So we should all just trust you anyway? Lovely. Thankyou for that lesson in logic.
People and the scientific community may have been skeptical of Einstein at first, but they were also skeptical of the many many many scientists and studies and theories that were also disproved. Its called Falsificationism.
Please do get back to us when you have some studies to back up your statements. Now I need to go and eat something, you see, I haven’t eaten for a while and I’m a little shaky.
David, for some one who calls others close minded to the truth acting like were some lost simpletons simply waiting to be saved from are self destructive lifestyles you seem to ignore anything that calls your religion…I mean diet into question. I have no doubt that people could loose weight on this diet plan simple calorie reduction will cover that aspect,and with the weight loss health would be noticeably improved.
What I debate is the idea that hunger is felt in the throat ,and that no one is truly experiencing hunger because of toxic build up; something that is completely unfounded, or the fact that food he perceives is bad will cause withdrawal symptoms. I’ll give you credit for bringing up the Vagus nerve and glossopharyngeal nerve(the Vagus which people have cut to suppress appetite), but there’s no mention of hunger being truly felt in the throat in any research.
Study after study shows us that weight loss in and of itself not micro nutrient or antioxidants is the biggest benefit to our health.
These diets come along with there ; strict, must be followed ,we are better than others attitude ,and it bothers me. With buzzword inclusions like Toxic Hunger ;something that separates the intelligent Nutritarians from the outsiders thus creating your own social click that ends up defining the people who take part in it frightens me.
When did diet become a religion that dared not be questioned.
P.S. Not all peanut butters have hydrogenated oils ,and peanut butter is actually quite healthy.
