Lent, Long Fasts, and Lasting Change: What Behavioral Science Teaches Us About Letting Go

Today is Ash Wednesday, the beginning of Lent—a season traditionally associated with fasting, reflection, and intentional sacrifice. Whether you observe Lent for spiritual reasons, cultural reasons, or not at all, this time of year offers a powerful psychological reminder: meaningful change requires intention, structure, and consistency.

Many people use this season to “give something up.” Sugar. Social media. Alcohol. Complaining. Overspending. The specific habit matters less than the process. What we’re really practicing is interrupting an automatic behavior pattern.

And that is both spiritual work and psychological work.

Fasting Is More Than Removal — It’s Rewiring

When we fast from something for an extended period—30 or 40 days, for example—we’re not just removing a behavior. We are disrupting a habit loop.

Habits form because they are easy, accessible, and reinforced. Your phone sits in the same place. The snacks are in the same cabinet. The bar is where your friends gather. The cue leads to the behavior, which leads to relief or reward.

If we want to change the behavior, willpower alone rarely works long term. What does work is application and consistency.

Behavioral science and addiction recovery work both point to the same truth:If you want different results, you often need a different environment.

Change the Environment, Change the Pattern

If you are fasting from your phone, it may not be enough to “try harder.” You might need to:

• Leave it in a different room.

• Silence notifications.

• Charge it somewhere out of reach.

• Replace scrolling time with a specific alternative (reading, walking, journaling).

If you are fasting from alcohol, it may not be enough to decline a drink. You may need to:

• Suggest different activities.

• Spend less time in settings centered around drinking.

• Be mindful about who you’re spending time with.

In addiction recovery, there’s a well-known principle: change people, places, and things.This isn’t about judging anyone. It’s about recognizing that behavior is relational and environmental. We are deeply influenced by context.

Even outside of addiction, this principle holds true. If your goal is to reduce gossip, constant exposure to gossip-heavy conversations will make change difficult. If you’re trying to reduce negativity, being immersed in chronic complaining environments will challenge that effort.

Lasting change often requires thoughtful restructuring—not just good intentions.

Fasting Reveals Attachment

Extended breaks do something important: they show us how attached we are.

You may notice:

• Restlessness

• Irritability

• Rationalization (“It’s not that big of a deal.”)

• Negotiation (“Just this once.”)

These reactions are not signs of failure. They are information.

They reveal where coping, comfort, boredom relief, or emotional regulation may have been outsourced to a habit. That awareness is valuable. It gives us a chance to build healthier replacements rather than simply removing the old behavior.

Consistency Over Intensity

Large fasts or extended breaks are powerful because they move beyond a single decision. They require daily re-commitment.

Change is rarely dramatic. It is repetitive. It is choosing again tomorrow.

Whether you are observing Lent as a spiritual discipline or simply using this season as a reset, consider:

• What habit has become automatic?

• What environment supports that habit?

• What needs to shift to support your goal?

• What will you practice instead?

Because fasting isn’t just about stopping something. It is about creating space for something healthier.

A Final Thought

You do not need to identify as “addicted” to benefit from the wisdom of recovery work. The tools developed in addiction treatment—awareness of triggers, environmental shifts, consistent boundaries—apply broadly to human behavior.

Long fasts teach us discipline.Environmental changes make discipline sustainable.Consistency makes change lasting.

Whether this season is sacred, reflective, or simply practical for you, may it be intentional. Change is possible—but it is rarely accidental.

And you do not have to do it alone.
