From the Passenger Seat: You Don't Need Another Diet. You Need Fewer Decisions.

A client told me she wasn't sure what was wrong with her, because by six o'clock, she genuinely didn't care what she ate. She'd usually just grab whatever was fastest, feel guilty about it, and tell herself tomorrow she'd do better.

We talked it through, and it had nothing to do with discipline. By six o'clock, she'd already made hundreds of decisions. What to wear. What meetings to prioritise. How to respond to a tricky email. Whether to say yes to the extra project. What to pack for her kid's lunch. Whether that comment from her sister meant something or nothing.

By the time dinner rolled around, her brain wasn't lacking motivation. It was just out of decisions to make.

Decision fatigue is real, and it's not a character flaw

This is such a common pattern that it has a name. Decision fatigue describes exactly what it sounds like, the quality of our choices gets worse the more decisions we've already made that day. It's not about willpower. It's closer to a muscle that's simply been used up.

And dinner is almost always the decision that lands last, at the exact moment your brain has the least left to give it.

So when someone tells me they "just can't seem to plan meals," I don't hear a lack of discipline. I hear someone whose exhausted six o'clock brain is being asked to make one more decision, on top of every other decision it made that day.

The fix isn't more willpower, it's fewer decisions

This is where I'd gently push back on the idea that she needs another diet, another meal plan app, or another round of trying harder. What she actually needs is to move the decision to a point in the day when she has more capacity to make it well.

In practice, that can be simpler than it sounds. Choosing three or four dinners you know you can make without thinking, and rotating them, so "what's for dinner" already has an answer before the question gets asked. Deciding on a Sunday, even loosely, so Wednesday-you isn't starting from zero. Keeping a short list of what actually works for you, so you're choosing from five options instead of facing an entire universe of possibilities at the most tired point in your day.

None of that requires more information about nutrition. She already has that. It just requires making fewer decisions when she has the least energy to make them well.

A gentler way to think about it

If dinner has been feeling harder than it needs to be, it's worth asking whether the problem is really about food, or whether food is just the decision that happens to land at the end of an already full day.

Because "I don't have willpower around food" and "I'm out of decisions by six o'clock" are two very different problems. Only one of them actually needs fixing at dinner.

If you want a simple starting point, my free Build a Better Breakfast guide takes one decision off your plate first thing in the morning, which is often the easiest place to start.
