No, it’s not. Really. Let’s find out why, shall we? And let's do it in 90 seconds. Take a breath... One more... Now watch...
For 99.99% of human history, food was in limited supply. Consuming more calories meant a better chance of survival. Our design matched our environment. This is why we're still around.
Now, food is nearly unlimited. Consuming more calories means getting fat. Our design doesn't match our environment. This is why it's not your fault.
In the future, we'll adapt and begin to prefer lower calorie foods, like broccoli over cake. Our design will again match our environment. If we're still around.
Pick an option below to see how your body was designed to survive in a limited food environment.
AN INCREDIBLE SYSTEM Humans store extra calories instead of pooping them out. Why? This was really useful for having fuel available in case we couldn't find food for a while — which was the situation for 99.99% of our existence. Now? Not so much.
HOW DOES IT WORK? When we eat calorie-dense foods, taste buds send signals to our brains. Then our brains release chemicals. And those chemicals make us feel great! It's a built-in guidance system — an instinct — for choosing high-calorie foods over low-calorie foods.
YOUR STOMACH TALKS TO YOUR BRAIN When we eat, our stomachs don't let our brains know we're full until 20–30 minutes later. This design mechanism enables us to consume more calories than we need at the moment — great for when the next meal was uncertain, not so great for our three-meal days.
VILLI OR VILLAINS? Our intestines have millions of finger like projections called villi. These increase the surface area over which food can be absorbed so we can extract the most calories possbile as food passes through us. Again, brilliant — for an existence where food is scarce.
