Back in 1945, the Food and Nutrition Board said adults need about 2.5 liters of water a day. Sounds sensible, right? The problem? They forgot to mention that most of that water comes from the food you eat—your morning orange, that sad salad at lunch, even the pasta you had for dinner. Somewhere along the line, people only heard “drink eight glasses” and turned it into a rigid, anxiety-inducing chore.
If you’re walking around with a giant jug like a hamster in a water bottle, you might be overdoing it. You could be one of those brave souls who power-walks to the bathroom every fifteen minutes, earning some serious cardio. The truth is, your body is a fantastic, stupidly clever machine that already tells you when it needs fuel.
