The Anchor Wasn't Enough

Week two of prepping a healthy snack every day. The habit stack was textbook correct and it still didn't always fire. Here's what actually closed the gap.

I’m two weeks into an experiment. Prep a healthy snack every day.

Week one I got four out of five. The day I missed I’d made extra the day before, so it covered itself. Week two is still going.

Here’s the part I didn’t expect.

The setup was right and it still didn’t always happen

I anchored the snack to making breakfast. I’m already in the kitchen. The knife is already out. Attach the new thing to the thing you already do.

That’s not my idea. It has a name, implementation intentions, and it’s one of the better-supported ideas in behavior change. If-then plans work.

And some mornings it just didn’t happen anyway.

Someone needed something. A text came in. I’d walk out of the kitchen with my coffee and the snack never got made. The anchor was sitting right there. I wasn’t.

Nobody tells you that part. The advice stops at “attach it to something you already do,” like the cue does the whole job. In my experience the cue gets you most of the way and then real life takes the last few feet.

What closed the gap was a reminder showing up at the right moment. I use Summit myself, so it texts me. Nothing clever about it. Just “make the snack” landing while I was still near the kitchen instead of forty minutes later when it didn’t matter anymore.

That’s the honest version of week two. The anchor plus a nudge. Not the anchor on its own.

Then I made it smaller

This is the other half, and I think it’s the bigger half.

A snack is not a recipe. It’s not a Sunday afternoon with containers. Here’s my actual definition now.

I grab a vegetable. I cut it up. That’s a snack.

I grab a fruit. I open it. That’s a snack.

No assembly. Nothing compiled. Chop and go.

What I’ve actually made in two weeks: peppers. A banana. Nuts. No-bake balls, which take slightly more doing, but they’re basically the same ingredients as my breakfast, so it’s an add-on rather than a new project.

The second this became a recipe it was going to die. It survived because it stayed boring.

One that pays for itself

Not everything has to be same-day. Last week I roasted chickpeas in the air fryer and they lasted four days. One effort, most of a week covered.

I’d do more of those. The prep isn’t separate from the habit, it is the habit, just front-loaded.

Run it back

Two weeks is early and I don’t want to oversell it.

The research on this is less tidy than the internet suggests. A 2024 review of twenty studies put the median somewhere around two months before a health habit starts feeling automatic, with enormous spread between people. Four days for some. Nearly a year for others.

So I’m not done. I’m two weeks in, it’s holding, and the honest read is that it’s holding because I made it smaller and because something reminds me when I drift.

I feel good. That’s worth something even if it isn’t the point yet.

Next week I run it back. Same habit, nothing new.

What’s one small thing you want to try? Not a whole new life. One thing.
