How to Eat Without a Protocol
Share
Hunger is older than food science. Most people have forgotten this.
There are currently at least a dozen distinct frameworks for how you should eat. Time-restricted feeding. Carnivore. Mediterranean. Whole30. Plant-based. Low-glycemic. Each has its defenders and its metrics and its peer-reviewed evidence. Each also has a foundational claim that is quietly extraordinary: that eating — an act humans performed successfully for three hundred thousand years before any of this existed — requires expert guidance.
Something happened around the late 2000s when food became a problem to solve rather than a thing to do. The timing is not coincidental. It follows the quantified self movement, which made the body into a data source. It follows the rise of ambient health anxiety, in which even apparently healthy people were made to understand they were probably getting something wrong. It follows the influencer economy, which found wellness a better growth category than almost anything else. The result is a culture in which choosing what to eat is now experienced as a high-stakes decision that requires a strategy.
Hunger is not a notification. It arrives the way cold air arrives through a window you didn't notice was open — the body's language for its own requirements, a system that calibrated itself long before anyone had an opinion about fasting windows. Epidemiologist and food policy researcher Marion Nestle spent decades documenting how food industry marketing — not physiology — created most of what people now call nutritional confusion. The confusion is the product. The protocol is sold as the cure.
The problem with eating according to a protocol is that it relocates the authority outside the person. You stop trusting the cues your body sends and begin trusting a framework built by someone else for a different body with different goals and probably a book deal. This is not health. It is outsourced judgment.
There is also a pleasure problem. The sensory information available at a table — the smell of something cooking, the texture of bread, the sound of a wine being poured — is itself nutritionally significant in the sense that it affects digestion, satiety, and the experience of being a person who eats. Cephalic phase responses — the term used in physiology for the anticipatory processes triggered by smell, sight, and taste, including saliva production, insulin release, and digestive enzyme activity — account for a meaningful portion of how the body processes a meal. You cannot count these in a tracking app. You cannot enter them into a macro calculator. Pleasure is partly structural.
Intuitive eating, the framework developed by dietitians Evelyn Tribole and Elyse Resch in the 1990s, was an early attempt to name what was being lost. Its core claim — that internal signals of hunger and fullness are more reliable guides than external rules — sounds obvious until you remember that the entire food wellness industry exists to convince people the opposite is true. Tribole and Resch were arguing against diet culture. Their framework has since been absorbed into wellness culture in ways that don't entirely serve that original point. Intuitive eating now has its own protocols. It has curricula and coaches and certification programs. The format recaptured the content.
What the framework got right, before it got complicated, is that eating is information processing. Hunger is information. Fullness is information. So is the company you're in and the table you're sitting at and the fact that it's raining outside and someone you like is across from you.
Every cuisine that has survived long enough to become a tradition has encoded this. The Japanese concept of ichiju-sansai — one soup, three sides — is not a macro distribution. It is a visual grammar for a balanced meal that developed through collective practice over centuries. The French approach to eating, documented in research examining what epidemiologists called the French paradox, involves longer meal duration, smaller portions by default, and cultural conventions against eating while doing something else. These are not protocols. They are sedimentary practices. They developed because they worked.
The issue with protocols is that they are the opposite of sedimentary. They are designed in controlled conditions, for a specific hypothesis, to demonstrate a measurable outcome. They produce results in twelve-week studies. They often do not survive contact with a life.
There is a version of eating that requires no framework at all. It is not reckless and it is not naive. It involves paying attention to what the body says, eating things made with some care, sitting somewhere you can be present for it, and not treating the meal as a data point. This is what most people's grandparents did — not because they were enlightened, but because there was nothing to sell them.
You will not remember what you ate. You will remember who you were with and whether it was good.
