Why Your Blood Sugar Crashes at 3pm (And What Actually Fixes It)
If you've ever hit a wall around 3pm — foggy, irritable, suddenly starving even though you ate lunch two hours ago — you're not imagining it, and it's not a willpower problem. It's almost always what was on your plate at lunch.
A lunch built mostly around refined carbohydrates spikes blood sugar quickly, and what goes up quickly comes down quickly. That crash is your body asking, urgently, for the fuel it just lost — which is why the 3pm slump so often ends in a trip to the vending machine.
The fix isn't cutting carbs out entirely. It's pairing them with enough protein, fiber and fat that the rise — and the fall — is gentler. In practice, that means rethinking the shape of lunch more than the size of it.
Use meals, walking, timing and pairing experiments to learn your own patterns.
