Bet You Can’t Eat Just One: How Food Companies Engineer Us to Keep Eating

Aug 24, 2026 by Rob Bratcher

There is a peculiar experience almost everyone in America knows. You open a bag of chips intending to eat a few. Ten minutes later you reach into the bag and touch the bottom. There was no real decision to eat the whole thing. You were not particularly hungry by the end. You may hardly remember eating the last third of the bag. Compare this with eating three baked potatoes, a bowl of oatmeal or four apples. At some point the body begins making its opinion known. The food becomes less interesting. Your stomach fills. Eating slows down. Eventually another bite sounds like work. Something different happens with a Dorito. That difference is worth understanding, because for the past several decades we have tended to explain overeating as a failure of character. People need more discipline. They need to count their calories. They need to stop snacking. They need to control themselves. There is certainly a place for personal responsibility. At Wholly Mountain, I spend a great deal of time helping people take responsibility for their health. But responsibility works better when we understand what we are up against. A Dorito is not simply corn, cheese and salt assembled into a triangle. Products like it are the result of modern food science, sensory testing and industrial manufacturing capable of manipulating characteristics that humans have always used to decide whether food is valuable: sweetness, saltiness, fat, aroma, texture, temperature, energy density and the physical speed with which food can be eaten. The remarkable part is not that food companies figured out how to make food taste good. Human beings have been doing that for thousands of years. The remarkable part is the precision.
