Relocating 300 Extremely Obese People from NYC to Cairo
Obesity Is Engineered: What Cairo Can Teach New York
Imagine if we moved 300 of NYC's heaviest people to Cairo. Why experts believe most would lose weight and what our cities can learn from it.
Obesity is a complex disease with genetic, psychological, and environmental roots. But today, we're going to explore one powerful factor we often overlook. We often treat extreme obesity as a personal failure, a catastrophic collapse of willpower. But what if the real culprit isn’t us at all, but our cities?
Consider this: New York City and Cairo, Egypt are urban twins. Both metropolitan areas pulse with the energy of over 20 million people. Yet, when you zoom in on one shocking statistic, they couldn’t be more different. For people weighing 600 pounds or more, a life-threatening level of obesity, New York’s rate is five to seven times higher than Cairo’s.
The People Aren’t Different; the Environments Are
Cairo faces its own health challenges. However, the key differences in their food systems and urban design create a significantly different set of default options for their citizens. This isn’t about blame; it’s about design. Our cities are engineered in ways that silently shape our choices, our health, and our bodies.
The Issue Isn’t Food Supply, It’s Food Design
Picture a New Yorker walking past rows of dollar-slice pizza shops, bodegas stocked with chips and soda, and drive-thru windows open late into the night. Now picture a person living in Cairo weaving through an open-air market, where baskets of tomatoes, beans, flatbread, and herbs spill into the street. Both cities are full of food—but the default choices are worlds apart. Cairo’s abundance is fresh and local; New York’s abundance is processed and packaged.
Our Environment Hijacks Our Brains
Imagine our group of New Yorkers not only starts walking more and eating traditional foods in Cairo. Imagine they also experience a sudden cessation of the constant psychological barrage. No more fast-food jingles on TV. No smell of pretzels and pizza pumped onto every street corner.
The visual landscape of food shifts from bright, hyper-processed packages to the natural colors of produce in a market. The relief for their overtaxed neural reward pathways would be as significant as the physical change. It's happening at a subconscious level, we are barely equipped to fight.
Food scientists don't just make food tasty; they engineer it to be hyper-stimulating. The vibrant, unnatural colors of candies, sodas, and packaged foods are designed to signal extreme reward to our brains. The specific combination of fat, sugar, and salt is engineered to be addictive, hitting all the pleasure points and encouraging us to eat past the point of fullness.
A Year in Cairo for NYC's Super Obese
- Walk More: Cairo’s dense, vibrant streets are built for pedestrians, not just cars. Daily errands naturally involve thousands more steps.
- Eat Differently: The default food option shifts from ultra-processed fast food (ubiquitous in NYC) to traditional diets rich in beans, grains, and fresh vegetables from street markets.
- The Culture of Food is Different: Meals are often social, home-cooked events, not rushed calories grabbed on the go.
This isn’t speculation. Migration studies prove this effect in reverse. When people move from countries with lower obesity rates to the United States, they often gain significant weight by adopting the local diet and sedentary lifestyle. Our thought experiment simply applies that same logic in the opposite direction.
What Health Experts Say
“It’s amazing how quickly people are changing.”
“They walk less, ride more, watch more television and eat a diet higher in fat and sugars.”
“They look more and more like U.S.-born kids — and that’s a bad thing in this case.”
“Obesity risk increases with acculturation and time spent in the United States.”
Why the Dramatic Difference? It’s the System, Not the People.
The stark disparity in extreme obesity rates points to a fundamental truth: personal choice is only one piece of the puzzle. Our cities are literally engineered to make us sick, creating what public health experts call obesogenic environments, places that systematically encourage overeating and discourage movement.
| Feature | New York-Style Obesogenic Environment | Cairo-Style (Less Obesogenic) Environment |
|---|---|---|
| Food Environment | High density of fast-food outlets; ultra-processed foods are cheap and convenient. | Street markets with fresh produce; traditional diets are still the cultural norm. |
| Built Environment | Designed for cars in many areas; public transit often involves long waits. | Extremely walkable urban core; daily life requires more incidental activity. |
| Default Options | The easiest, quickest choice is often the unhealthiest. | The easiest, quickest choice is often a whole food (e.g., fruit, beans, flatbread). |
How Do We Fix Our Cities? Shift from Shaming to Systems.
- Design for Movement: Prioritize walkable neighborhoods, protected bike lanes, and accessible green spaces.
- Fix the Food Landscape: Zone to limit fast-food near schools, and subsidize fresh fruits and vegetables in "food desert" neighborhoods.
- Invest in Public Health: Mandate healthier school meals, restrict junk food advertising to children, and promote walking and cycling as transportation, not just exercise.
These systemic changes remove the burden of constant resistance from individuals. They acknowledge that willpower is finite, and no city should be designed to exhaust it by lunchtime.
What Cairo Can Teach NYC About Extreme Obesity
The story of NYC and Cairo isn’t about which city is better. It’s a reminder that health is not solely an individual achievement or failure. It is profoundly shaped by the world outside our front door. Addressing the environment isn't a silver bullet that will erase the role of genetics or individual responsibility.
Instead, it's about making healthy choices the easier choices, reducing the constant burden on individual willpower, and creating a world that supports rather than sabotages our health. By shifting the conversation from shame to systems, from individual blame to collective responsibility, we can start building cities that help us thrive, not just survive. Our well-being depends on it.
Willpower Starts the Journey, but Environment Decides the Distance
Willpower alone can’t overcome a city built to work against you. The same 300 New Yorkers in Cairo would find their internal resistance no longer under constant siege: the streets, the markets, and the cultural defaults all support healthier choices. Willpower sparks the change, but the environment carries it forward. If we want healthier cities, the lesson is clear: stop designing spaces that exhaust our self-control and start building ones that make thriving inevitable. In the battle against obesity, systems win where sheer willpower cannot.
