What Is The End of Craving About?
Picture two countries sharing a disease. In the early twentieth century, both the American South and northern Italy were devastated by pellagra, a nutritional deficiency caused by corn-heavy diets that caused bleeding gums, skin lesions, delirium, and death. Both countries solved it. America added niacin to refined flour. Italy promoted rabbit meat, communal bread baking, and wine. A hundred years later, Mississippi has an obesity rate of 37 percent. Northern Italy, where people eat mortadella, butter-cream risotto, fried veal cutlets, and full-fat gelato, has an obesity rate of roughly 8 percent.
Mark Schatzker, a food writer and journalist in residence at Yale’s Modern Diet and Physiology Research Center, spent years trying to understand why. The End of Craving is his answer. The obesity crisis, he argues, is not caused by weak willpower, bad genes, or any single macronutrient. It is caused by what happened when food technology began sending the brain signals that food could no longer back up.
The book sits alongside David Kessler’s The End of Overeating as essential reading on compulsive eating. Kessler explained what the food industry did. Schatzker explains why it worked, at the level of neurons and prediction errors. Read them back to back and you get a complete picture.
Why Do Cravings Keep Coming Back?
Most people assume cravings are the problem. Schatzker’s central argument is that cravings are the symptom, not the cause. The brain evolved a sophisticated nutritional intelligence system over hundreds of millions of years. Flavor was information. Sweetness meant calories were coming. Fat meant energy density. Bitterness warned of toxins. The brain read these signals with extraordinary precision, steering appetite toward what the body actually needed.
The slot machine broke that system.
Neuroscientist Kent Berridge spent years separating what he calls wanting and liking, two systems that most of us assume are the same thing. Wanting is dopamine-driven: the urge to pursue food, the restless seeking, the compulsion to keep eating. Liking is opioid-driven: the actual pleasure of eating something good. These circuits operate independently. A person can want intensely without liking at all. Berridge’s famous rat experiments showed this directly: destroy the dopamine system and rats lose all motivation to seek food, even though they still enjoy eating when food is placed directly in their mouths. They like, but can’t want. Modern food engineering, Schatzker argues, does the reverse. It cranks wanting without delivering genuine liking, which is why eating from a processed-food environment can feel compelled and joyless at the same time.
Uncertainty makes this worse, not better. When a signal is reliable (sweetness always means calories), the brain receives confirmation and the wanting circuit resolves. When a signal is unreliable (sweetness sometimes means calories, sometimes means zero), the brain’s nutritional accounting stays open. An unresolved prediction creates the same effect as a slot machine: unpredictable rewards drive more persistent, compelled behavior than predictable ones. The brain, unable to close its caloric accounting, keeps seeking. The drive intensifies.
Schatzker traces this problem through the entire modern food supply: artificial sweeteners, fat replacers, flavor chemistry that makes things taste like what they’re not, vitamin-fortified refined carbohydrates. Each of these is a food that says one thing and delivers another. And each one sustains the craving it was meant to solve.
Do Artificial Sweeteners Actually Help With Weight Loss?
Purdue University researcher Susie Swithers ran an experiment that should have caused a national conversation. Rats fed saccharin-sweetened yogurt (sweet but no calories) gained more weight than rats fed sugar-sweetened yogurt (sweet and calories delivered). Not because saccharin has hidden calories. Because the mismatch between the sweetness signal and the caloric reality trained the brain to distrust the signal entirely.
Yale neuroscientist Dana Small extended this with human subjects. People drank five beverages, all equally sweet, but each with a different caloric content. When sweetness matched calories, the brain’s wanting circuits quieted down and registered satisfaction. When sweetness arrived without calories, or with fewer calories than the taste predicted, those circuits stayed active. The brain detected the mismatch. And its response was to sustain the drive to keep seeking.
Ivan de Araujo’s mouse experiments made the mechanism even clearer. When he gave mice a drug that blocked sugar from being metabolized into fuel, the mice stopped preferring sugar water. What the brain ultimately cares about is not how food tastes, but whether food is useful. Useful means: does what it promises.
“For hundreds of millions of years, every one of our ancestors labored to feed themselves. Some won, some lost. But when food was obtained, it didn’t tell lies. Fat tasted like fat. Sugar tasted sweet. And only strawberries tasted like strawberries.”
This is Schatzker’s foundational point. Modern food technology didn’t just add artificial flavors or reduce calories. It broke the signal integrity the brain had been relying on for hundreds of millions of years. The diet products designed to help people eat less may have made the wanting problem worse, not better, by flooding the food supply with mismatched signals.
Why Is Italy Thin When It Eats Pasta, Cheese, and Gelato?
Schatzker spent time in northern Italy trying to understand what nutritional orthodoxy cannot explain. The food there is rich: mortadella, lardo, steak tartare, tortellini in cream, tagliatelle in ragù, fried veal cutlets stuffed with ham and white truffle. Northern Italians eat plenty of butter, refined pasta, wine, and full-fat dairy. They do not count calories. And they have obesity rates far below American levels.
The answer is not olive oil. Northern Italians cook with butter. The answer is not portion control. Schatzker describes meals in Bologna that would be considered excessive by any American dietary standard. The answer is signal integrity.
Italy never fortified its flour with synthetic vitamins. It never mainstreamed artificial sweeteners or fat replacers. It never industrialized food culture in ways that decouple flavor from nutrition. When an Italian eats mortadella, the fat content is exactly what the taste predicts. When an Italian eats gelato, the sweetness and the calories arrive together, the prediction resolves, and the wanting circuit quiets down. The brain gets an honest answer, and it stops asking.
Chef Pino Mastrangelo, interviewed in Bologna, put it plainly: “The difference between feeding and eating. Italians don’t want just to feed themselves, they want to eat. They want an experience.” Not an indulgence or a cultural quirk. The mechanism by which a traditional food culture maintains an intact relationship between flavor, nutrition, and appetite.
Schatzker contrasts two questions. The quintessential American question about food: “How will this affect my body?” The quintessential Italian question: “Is this the best recipe?” One frames food as an adversary to be managed. The other places the eater in a relationship of trust. The difference in outcomes is not subtle.
One of the book’s most provocative arguments concerns vitamin fortification. In 1941, the US government mandated adding B vitamins to refined flour, which eliminated pellagra. A genuine public health victory. But Schatzker asks the question nobody thought to ask: what happened to appetite when niacin became available in white bread?
Before fortification, Americans consumed beans at historically high levels. Beans are rich in niacin. After fortification, bean consumption began declining, bottoming out around 1980, just as the obesity epidemic was accelerating. The internal appetite signal that had been steering people toward diverse whole foods was satisfied without requiring those foods. The body’s nutritional intelligence was short-circuited. University of Illinois researchers in 1947 found the same thing in pigs: pigs fed B-vitamin-fortified feed in confinement gained weight 40 percent faster than pasture pigs who could eat freely from a range of foods and exercise their own nutritional wisdom. Today’s industrial pigs receive up to twenty times as much riboflavin as 1950s pigs. The parallel is uncomfortable and deliberate.
Is The End of Craving Worth Reading?
Read this if you’ve used diet products (diet soda, artificial sweeteners, fat-free versions of foods you love) and found that your cravings got worse rather than better. Also read it if you’re curious about why wanting and enjoying can come completely apart, why the Italian paradox exists, or why restriction alone seems to make the problem worse over time. Schatzker writes with genuine intellectual warmth, and the pellagra history alone is worth the price of the book.
Skip it if you want a clear protocol. Schatzker deliberately avoids prescribing a program, which is philosophically consistent with his argument (any rigid set of rules is another form of the same intervention) but may frustrate readers who want a specific action plan. The direction is clear: eat real food that accurately signals its nutritional content, minimize mismatch, restore signal integrity. The implementation is left to you.
One caveat: The book was published in 2021 and doesn’t address GLP-1 medications, which have since become the dominant development in appetite regulation. GLP-1 agonists work in part by reducing the wanting signal, which maps interestingly onto Schatzker’s wanting/liking framework. His mechanistic explanation of what’s broken in the appetite system is more relevant than ever, not less.
