The boss asked us to write about something that most people feel in their gut but rarely see spelled out: the food industry does not want you to be healthy. It wants you to be hungry. More precisely, it wants you to keep eating, because that is how it grows.
This is not a conspiracy theory. It is a business model. And understanding food industry obesity as a structural outcome, not a personal failure, changes everything about how you look at your next meal.
The Problem: Fewer Mouths, Same Shareholders
Global birth rates are falling. The World Health Organization reports that populations are aging and growth is slowing across nearly every developed nation. For most industries, this is a planning challenge. For the food industry, it is an existential threat.
Food companies are not like tech companies. They cannot invent a new gadget every year. They sell calories. If fewer people are born, fewer calories are sold. The only way to keep revenue climbing is to get existing people to eat more.
And that is precisely what happened. According to nutritionist Marion Nestle of New York University, the number of calories available in the American food supply went from roughly 3,200 per person per day in 1980 to 4,000 by the year 2000. The USDA confirmed that the total amount of food available per person increased 16 percent between 1970 and 2003. Nobody asked for that food. It was produced, and then the industry had to figure out how to get people to eat it.
Food Industry Obesity: Engineered to Be Irresistible
The food industry did not leave this to chance. It hired scientists.
The concept is called the “bliss pointThe precise combination of sugar, salt, and fat in a food product that maximizes pleasure and craving without triggering the brain's fullness signals.,” a term coined by market researcher Howard Moskowitz in the 1990s. It refers to the precise combination of sugar, salt, and fat that triggers maximum pleasure without triggering the brain’s fullness signal. According to US Right to Know, manufacturers use rigorous focus-group testing and psychological research to find this sweet spot for every product. The bliss point triggers a spike in dopamine, the brain’s pleasure chemical, followed by a crash that generates a craving for more.
This is not cooking. It is engineering. And the results are measurable.
In 2019, the National Institutes of Health published a landmark study led by researcher Kevin Hall. Twenty volunteers were placed on either ultra-processed or unprocessed diets for two weeks each. The meals were matched for calories and nutrients. The result: people on the ultra-processed diet ate about 500 more calories per day and gained roughly 2 pounds in just two weeks, without even realizing they were eating more.
“This is the first study to demonstrate causality,” Hall said, “that ultra-processed foodsIndustrially manufactured food containing additives and substances rarely found in home cooking, such as emulsifiers, colorings, and artificial flavor enhancers. cause people to eat too many calories and gain weight.”
Bigger Portions, Bigger Profits
If engineering taste was step one, engineering size was step two.
A study published in the American Journal of Public Health by researchers Lisa Young and Marion Nestle documented how portion sizes began growing in the 1970s, rose sharply in the 1980s, and have continued climbing since. French fries, hamburgers, and soda are now 2 to 5 times larger than when they were first introduced. The researchers found that “profits for most food items rise consistently when manufacturers increase product size.”
This was not consumer demand. In the 1970s, fast-food marketing directors realized that customers would buy more if portions were bigger and pricing made larger sizes seem like a bargain. A 16-ounce drink might cost 5 cents per ounce, while a 32-ounce version costs only 2.7 cents per ounce. The extra ingredients cost almost nothing. The extra revenue does not.
When Science Was for Sale
Perhaps the most damaging tactic was corrupting the science itself.
A 2016 investigation published in JAMA Internal Medicine revealed that the Sugar Research Foundation paid Harvard scientists in the 1960s to produce a literature review that blamed fat, not sugar, for heart disease. The foundation set the review’s objectives, contributed articles for inclusion, and received drafts before publication. The funding was never disclosed. The resulting paper, published in the New England Journal of Medicine in 1967, shaped American dietary guidelines for decades, steering public health advice away from sugar and toward low-fat diets that often replaced fat with added sugars.
This was not a one-time event. As Marion Nestle has documented throughout her career, food companies routinely fund research that produces favorable conclusions. The pattern is simple: fund a study, frame the question, publish the result, cite the result in lobbying.
$14 Billion in Persuasion
The food industry spends roughly $14 billion a year on advertising in the United States, according to the UConn Rudd Center for Food Policy and Health. More than 80 percent of that goes to promoting fast food, sugary drinks, candy, and unhealthy snacks. A significant portion targets children and communities of color.
When regulators try to push back, the lobbying machine activates. The Environmental Working Group documented how food and biotech companies spent tens of millions fighting labeling requirements alone. The industry has successfully blocked, weakened, or delayed front-of-package nutrition warnings, soda taxes, and advertising restrictions aimed at children in country after country.
The Tobacco Connection
There is a reason the food industry’s playbook feels familiar. Parts of it were written by tobacco companies.
In the 1980s, Philip Morris purchased General Foods and Kraft. R.J. Reynolds acquired Nabisco. A study published in the journal Addiction found that these tobacco firms applied the same tactics they had used to formulate and market cigarettes: optimizing products for maximum reward, targeting vulnerable populations, and fighting regulation at every turn. By the time the tobacco companies spun off their food divisions in the 2000s, the strategies were baked in.
Today, about 57 percent of the calories American adults consume come from ultra-processed foods. For children, that figure is 67 percent.
The Bottom Line
One in eight people on Earth now lives with obesity, according to the WHO. In 2022, 2.5 billion adults were overweight. Obesity rates have more than doubled since 1990 and quadrupled among adolescents. If nothing changes, the global economic cost of obesity is projected to hit $18 trillion per year by 2060.
The ultra-processed food market, meanwhile, is projected to grow by $856.6 billion between 2025 and 2029.
These two numbers are not in tension. They are the same story. The industry grows because people eat more. People eat more because the food was designed that way. And the people who designed it are spending billions to make sure nothing changes.
None of this means that personal choices do not matter. But it does mean that framing obesity as a failure of willpower is exactly what the industry wants you to believe. The environment was engineered. The science was bought. The portions were inflated. The labels were fought. Blaming the individual for the result is like blaming the fish for the hook.
The boss wanted this one written, and it is the kind of story that gets more unsettling the deeper you look: the food industry does not want you to be healthy. It needs you to eat more. Not because of some cartoonish villainy, but because of something much more mundane. Quarterly earnings.
Understanding food industry obesity as a systemic outcome rather than a collection of bad individual choices requires following the money, the science, and the regulatory captureThe process where a regulated industry shapes the legislation meant to regulate it, often resulting in rules that benefit the industry more than the public interest. that connects them. Here is the full picture.
The Demographic Trap
The food industry faces a fundamental arithmetic problem. Revenue equals price times volume. Price increases are constrained by competition and consumer sensitivity. That leaves volume. But volume growth historically depended on population growth, and population growth is decelerating across every major market.
Birth rates in the United States, Europe, Japan, South Korea, and China have fallen below replacement level. The food industry cannot create new customers biologically, so it must extract more consumption from existing ones.
This is not speculation. It is reflected in corporate strategy. Marion Nestle, professor of nutrition at NYU, has tracked this dynamic for decades. She points out that the calories available in the American food supply rose from approximately 3,200 per capita per day in 1980 to 4,000 by 2000. The USDA’s own data shows per capita food availability increasing 16 percent between 1970 and 2003. The supply expanded not because demand increased, but because production capacity did, and the industry needed to monetize the surplus.
“The whole purpose of a food company is to get people to eat more of its products,” Nestle told the University of Chicago’s Big Brains podcast. “If following basic dietary advice to eat food, not too much, mostly plants, nobody’s making much of a profit off of that.”
Engineering Consumption: The Bliss PointThe precise combination of sugar, salt, and fat in a food product that maximizes pleasure and craving without triggering the brain's fullness signals.
The food industry’s solution to stagnant population growth was to make food more compelling at a neurological level.
The key concept is the “bliss point,” coined by American market researcher Howard Moskowitz in the 1990s. It describes the optimal combination of sugar, salt, and fat that maximizes sensory pleasure without triggering satiety. US Right to Know documents how manufacturers identify this point through extensive testing. When Dr Pepper attempted to formulate a new flavor, it ran through 61 formulas and 4,000 tasting events, each variation calibrated to find the precise peak of the hedonic curve.
The mechanism is dopaminergic. The bliss point triggers a dopamine spike followed by a crash, generating a craving cycle similar to what is observed with other addictive substances. A 2023 review of 281 studies across 36 countries, published in the BMJ, found that 14 percent of adults and 12 percent of children met criteria for addiction to ultra-processed foodsIndustrially manufactured food containing additives and substances rarely found in home cooking, such as emulsifiers, colorings, and artificial flavor enhancers., comparable to addiction rates for alcohol (14 percent) and tobacco (18 percent).
Michael Moss, in his book Hooked: Food, Free Will, and How the Food Giants Exploit Our Addiction, noted: “Measured in milliseconds, and the power to addict, nothing is faster than processed food in rousing the brain.”
The Hall Study: Proving Causation
For years, the link between ultra-processed food and overeating was associational. Observational studies showed correlations but could not prove causation. That changed in 2019.
Kevin Hall’s team at the National Institutes of Health conducted the first randomized controlled trial on ultra-processed food consumption. Twenty adults were admitted to the NIH Clinical Center for a continuous month. Each spent two weeks on an ultra-processed diet and two weeks on a minimally processed diet, in random order. The meals were matched for presented calories, macronutrients, sugar, sodium, and fiber.
The results were unambiguous. On the ultra-processed diet, participants consumed 508 more calories per day on average. They gained 0.9 kilograms in two weeks. On the unprocessed diet, they lost an equivalent amount. Participants ate faster on ultra-processed foods and did not report feeling more satisfied.
“This is the first study to demonstrate causality,” Hall stated, “that ultra-processed foods cause people to eat too many calories and gain weight.”
Subsequent analysis suggested that hyperpalatabilityThe engineered quality of certain processed foods that makes them extremely pleasurable to eat, designed to encourage consumption beyond normal fullness. and calorie density were primary drivers. The speed of consumption also played a role: ultra-processed foods are engineered to require less chewing, which reduces the time between ingestion and the delayed satiety signals from the gut.
Portion Inflation as Revenue Strategy
Increasing the addictive potential of food was one growth strategy. Increasing the physical quantity sold per transaction was another.
Young and Nestle’s landmark 2002 study in the American Journal of Public Health documented systematic portion inflation beginning in the 1970s and accelerating through the 1980s. Their findings were granular: cookies exceeded USDA standard portions by 700 percent. Cooked pasta exceeded standards by 480 percent. Muffins by 333 percent. French fries, hamburgers, and soda were 2 to 5 times larger than when originally introduced.
The economic logic was straightforward: the marginal cost of adding more food to a serving is low, but the marginal revenue is high. A 7-Eleven 16-ounce Gulp cost just under 5 cents per ounce; a 32-ounce Big Gulp cost 2.7 cents per ounce. The customer perceived a bargain. The company captured a larger transaction. And critically, research consistently showed that people ate more when given larger portions, often consuming 30 percent more from a doubled serving without reporting increased fullness.
The indicators of this shift were everywhere. Automobile manufacturers began installing larger cup holders. Cookbooks reduced serving counts for identical recipes between editions. Restaurant dinner plates grew in diameter. Fast-food chains rebranded their smallest sizes upward: what McDonald’s once called its only size of french fries became the “Small.”
Capturing the Science
Making food more addictive and portions larger would have faced resistance if the scientific establishment had been sounding alarms. So the industry invested in controlling the science.
The most documented case is the Sugar Research Foundation’s intervention in coronary heart disease research. A 2016 analysis published in JAMA Internal Medicine, based on internal industry documents discovered at the University of Illinois Archives, revealed that the SRF paid two Harvard researchers to produce a 1967 literature review in the New England Journal of Medicine. The review singled out fat and cholesterol as dietary causes of heart disease while downplaying evidence implicating sugar. The SRF set the review’s objectives, selected articles for inclusion, reviewed drafts, and was never disclosed as a funder.
The consequences were enormous. American dietary guidelines for the next several decades emphasized reducing fat, which led food manufacturers to reformulate products as “low-fat” while adding sugar to compensate for lost flavor. The low-fat era, in retrospect, may have accelerated the very obesity epidemic it was intended to prevent.
As SRF president Henry Hass stated in a 1954 speech: if Americans could be convinced to eat less fat and replace those calories with carbohydrates, and if sugar maintained its market share of carbohydrates, “this change would mean an increase in the per capita consumption of sugar more than a third.” That was the goal, stated plainly, seven decades ago.
The Advertising and Lobbying Machine
The food industry reinforces engineered consumption with massive spending on both advertising and political influence.
The UConn Rudd Center for Food Policy and Health estimates annual food advertising expenditure at approximately $14 billion, with over 80 percent devoted to highly processed products. A disproportionate share targets children and racial minorities.
When governments attempt regulation, the industry mobilizes. The Environmental Working Group documented that food and biotech companies disclosed $27.5 million in lobbying expenditures related to GE labeling in just the first half of 2014, nearly three times their spending in all of 2013. The industry has fought front-of-package warning labels, soda taxes, advertising restrictions on children’s programming, and school nutrition standards with consistent success.
The ultra-processed food market is projected to grow by $856.6 billion between 2025 and 2029, driven by what the market research firm Technavio describes as “strong advertising and marketing efforts.” The industry does not hide the mechanism. It advertises it to investors.
The Tobacco Playbook
The resemblance between food industry and tobacco industry tactics is not coincidental. It is genealogical.
In the 1980s, Philip Morris acquired General Foods (1985, $5.6 billion) and Kraft (1988, $12.9 billion). R.J. Reynolds bought Nabisco in 1985 for $4.9 billion. Research published in the journal Addiction found that tobacco companies applied their core competencies to food: optimizing products with “combinations of rewarding ingredients to maximize palatability and profitability,” targeting children and minority communities, and fighting regulation through lobbying, funded research, and public relations campaigns.
The tobacco companies eventually divested their food holdings, but the strategies remained embedded in the corporate cultures and product lines they had shaped. Today, 57 percent of calories consumed by American adults come from ultra-processed foods. For American children, that figure is 67 percent.
The Scale of the Result
The WHO’s 2024 data quantifies where this has led. One in eight people on Earth now lives with obesity. In 2022, 2.5 billion adults were overweight, 890 million of them obese. Adult obesity has more than doubled since 1990. Adolescent obesity has quadrupled. Over 390 million children and adolescents aged 5 to 19 were overweight in 2022, including 160 million living with obesity.
The economic projections are staggering. If current trends continue, the global costs of overweight and obesity are predicted to reach $3 trillion per year by 2030 and more than $18 trillion by 2060. These are not just healthcare costs. They include lost productivity, disability, and reduced quality of life.
Structural Problem, Structural Solutions
None of this exonerates individual choices. But it reframes them. Telling people to “eat less and move more” while they navigate an environment engineered to override their satiety signals, informed by corrupted science, and reinforced by $14 billion in annual advertising is not public health advice. It is victim-blaming wearing a lab coat.
The interventions that have shown results are structural: soda taxes in Mexico and the UK, front-of-package warning labels in Chile, restrictions on food marketing to children in multiple European countries, and reformulation mandates that force manufacturers to reduce sugar and sodium content. The food industry has fought every one of these.
The food industry is not your friend. It is not your enemy in any personal sense. It is a system that has optimized itself, with extraordinary sophistication, to extract maximum caloric consumption from every human being it can reach. Recognizing that is not cynicism. It is the first step toward demanding that the system be redesigned to optimize for something other than revenue.
