The Overnight Epidemic That Hijacked Our Biology

For most of human history, finding a calorie bomb meant survival. When our ancestors stumbled on something rich in sugar, fat, and salt, binging wasn't just smart, it was essential. Our brains evolved to reward us with pleasure for eating these foods because food was the most important thing to worry about each day. Then the world changed overnight. Food became a product engineered to hijack that same biology. About half the products in a US grocery store are ultra-processed, designed with addictive levels of sugar, fat, and salt that make our reward centers go ballistic. Marketing strategies like value pricing and constant food ads push us to overeat, often without noticing. Most people don't get obese from massive failures of self-control. They just eat a little too much over a long period. Just the equivalent of half a Snickers over your maintenance calories per day compounds to almost 5 kg, or 10 pounds of fat, after a year. The results are staggering. In 2025, more than half of Europeans were either overweight or obese, plus one in three children. In countries like the US, Mexico, Chile, and Saudi Arabia, the numbers are even worse. This kills almost 4 million people each year. If trends continue, by 2050 one in three adults on Earth will be obese and half of humanity will be overweight. We tried fixing this with diets and healthy habit campaigns, but telling people to eat healthier and move more does very little in the real world. Most people gain back the weight they lose within a year or two, often more, because once you lose weight your body fights to bring you back to the fat baseline it was used to. The only reliable solution is a lifestyle change, eating calorie-dense food only occasionally or not at all, which feels like saying no to some of the best things in life. And then there's hunger, a really strong signal that's hard to ignore. How hungry you are is partly genetic. Through bad luck, you might experience a lot of food noise and think about eating constantly. In many people who become overweight or obese, their hunger signal becomes dysregulated. Even after losing weight, it can take a long time before your hunger adjusts downwards. This is exactly where GLP-1 drugs interact with our biology.
