When You Don’t Know What to Make for Dinner: What Scripture and Neuroscience Say About Decision Fatigue
Let’s be honest, we’ve all been there.
Standing in the kitchen after a long day of all the things when a well-meaning husband says, “Hey hon, what’s for dinner?” You immediately feel exasperated and wonder if anyone will notice if you serve cereal for dinner. Again.
You didn't used to feel this way about choosing what's for dinner. But now? You’d be perfectly fine if you didn’t ever have to answer that question again! Not because you don't care. Because you're out. Not out of love for your family or your work or your calling. But out of capacity to make one more decision.
If you're a Christian woman involved in leadership and caring for a family, the pressure to do it well is understandable, but you know the feeling I’m describing. It has a name: decision fatigue. And, friend, it’s not in your head. It’s real.
Maybe it doesn’t happen for you in the kitchen. But, we’ve all had a moment when it seems decision-making stalls completely out, and everything in you wants to say, “Just tell me what to do.”
What is Decision Fatigue?
Decision fatigue isn't a character flaw or a sign you're not cut out for leadership. It's a well-documented cognitive phenomenon: the quality of your decisions deteriorates the more decisions you make in a day, regardless of how important each one is. In your brain 'what should I make for dinner' and 'how do I respond to this hard email' draw from the same limited pool of mental energy and by evening, that pool of energy is often close to empty.
That means sometimes the wisest thing you can do is not decide anything.
Researchers believe both willpower and decision-making draw from that same pool of mental energy. It’s the work of the prefrontal cortex, the same part of your brain responsible for planning, discernment, and self-control. When the energy runs low, you're more reactive, more anxious, and more likely to either snap or shut down completely.
It’s related to what researchers call cognitive load, which is all about the sheer volume of information your brain is tracking and processing at any given moment, whether or not you're actively deciding anything. The more input your brain is sorting through, the less capacity you have left to decide well.
Sound familiar?
What Scripture Says About the Limits God Built Into You
Here's what's easy to miss: your limited capacity isn't a design flaw. It's a feature.
'He knows how we are formed, he remembers that we are dust.' (Psalm 103:14)
God did not intend you to run at full cognitive capacity from sunrise to sunset with no rest and no guardrails. He built rhythms of rest into creation itself–Sabbath–not as a reward for doing work but as a necessary part of the work. Decision fatigue is your body and mind doing exactly what they were designed to do: signal a limit.
The problem isn't that you have limits. The problem is that most of us were never taught to embrace them or plan for them. Instead, we push back with all our might and sometimes find ourselves in a bit of a mess as a result. Friend, there’s a better way.
Three Faith-Based, Brain-Informed Ways to Fight Decision Fatigue
1. Reduce the Number of Decisions and Pre-Decide When You Can
You don't need more willpower. You need fewer daily decisions competing for the same mental resource. This might look like:
Deciding your outfit, your morning routine, or your meals in advance, on a day when your mind is fresh.
Creating simple 'if this, then that' defaults for recurring situations, so they no longer require fresh judgment each time.
Batching similar decisions together instead of letting them interrupt your day at random.
Think of it as stewardship of your energy and decision-making capacity. It protects your best thinking for the decisions that actually require it.
2. Hardest DecisionsFirst
If decision quality declines through the day, the decisions that matter most deserve your earliest, freshest attention, not what's left over after everything else has drained you. Try identifying the top three decisions each day that matter most to you, the ones that actually require wisdom, prayer, and discernment, and give those attention before the smaller decisions have worn you down.
3. Press Pause and Decide What Can Wait
Not every decision to be made is truly urgent. When you notice the fog of fatigue setting in, the irritability, the mental stall, the 'I don't care, just pick something', that's often your cue to pause rather than push through.
That's the moment to trust. Remember Psalm 46:10? 'Be still, and know that I am God.'
Stillness is an invitation to trust God. This isn’t the same as avoiding a decision. It’s intentionality. It's actually the wisest, most faith-filled response when you’ve reached a limit. Some decisions really can wait until you're rested, fresh, and clear-headed.
Decision Fatigue Means You’re Human
If you've been feeling foggy, indecisive, or strangely exhausted by choices that used to feel simple, it could be that God is reminding you that you need Him. Because here’s the thing: God gave you limits so that you’d learn to rely on Him — not your own strength — for wisdom and impact that you can't manufacture through sheer willpower alone.
The reality is this: the outcome of every decision you make is ultimately in God’s control. That’s good news, friend. He’s got you! And He’s always working all things together for your good and His glory.
