Your office celebrates everything with food—there’s cake again. Research by Baumeister on decision fatigue shows deciding in the moment every time depletes willpower. The solution: have a policy, not a decision. “I don’t eat office cake” or “once per month” or “only for people I know.” The specific policy matters less than having one. When cake appears, execute the policy.

One thought like this, every morning.

You don’t need more information about eating. You need the right idea to show up at the right time — before hunger, before decisions, before habits kick in.

Every morning, 365 Changes sends you one. Not a meal plan. Not a rule. Just a question or idea to sit with while you make coffee. Each one is simple, but they accumulate — and slowly, the way you think about eating starts to shift.

There’s more to read here — a companion essay that goes deeper into this topic. It might explore why willpower fades by evening, how your kitchen layout shapes what you eat, or what it really means to become someone who simply eats well. Each one takes a few minutes and leaves you thinking.

There are 91 of them across five areas — identity, environment, knowledge, decisions, and troubleshooting — and a Reader membership unlocks them all.
