From Junk Food to Obsessive Clean Eating: Gluttony in the Age of the Healthy Body Cult

A theological and pastoral reflection on food, body obsession, and the virtue of balance


Introduction: From visible excess to disguised excess

In our times—marked by hyperconnection, image, and immediacy—food is no longer just nourishment. Today it is identity, ideology, a means of control or rebellion. In past decades, so-called junk food—high in calories, low in nutrients—was a clear symbol of gluttony: excess, indulgence, negligence. But today, we face a different, subtler phenomenon: obsessive clean eating, orthorexia, restrictive diets, and a body cult disguised as “health.” Paradoxically, this extreme control may be, in spiritual terms, just another face of the same capital sin: gluttony.

This article seeks to explore this phenomenon through the lens of the Church’s tradition, illuminated by the Word of God, the Desert Fathers, and the perennial wisdom of Catholic moral theology. Not as judgment, but as guidance. Not as condemnation, but as a path to freedom.


I. What is gluttony? A classical definition with contemporary resonance

Gluttony is not simply overeating. According to St. Thomas Aquinas, it is “disordered desire for food or drink.” In other words, it is a disordered relationship with food, whether through excess, delicacy, impatience—or even (and here the modern world begins to resonate) through a pursuit of control or purity that enslaves.

Christian tradition, from the Desert Fathers to moral theology manuals, identifies five classical forms of gluttony:

  1. Eating too soon (praepropere)
  2. Eating too eagerly (laute)
  3. Seeking overly elaborate or expensive food (nimis exquisite)
  4. Eating too much (nimis)
  5. Eating too voraciously (ardenter)

Today, we could add a sixth: the obsession with food purity as a new form of body idolatry. That is, when food is no longer just nourishment but a pathway to personal salvation—without God.


II. A cultural shift: from fast food to fit food

In recent decades, particularly in the Western world, we have witnessed a notable transition:

  • Yesterday: The sin of gluttony manifested in visible excess—overconsumption, neglect, laziness.
  • Today: Gluttony may present as extreme control, restriction, obsession with health, performance, and physical aesthetics.

Junk food still exists and remains a trap. But now, the culture of “fitness,” of “clean eating,” of extreme diets, intermittent fasting for vanity, or protein shakes as a substitute for an ordered life, has birthed a new spirituality without soul: the body as absolute.

This obsession not only affects mental and physical health but also spiritual life: it becomes a cult, an alternative morality where the good is “light,” the forbidden is “processed,” and the perfect is “toned.”


III. “Man shall not live by bread alone”: food and the soul

Jesus Himself, when tempted in the desert, responded to the devil:

“Man shall not live by bread alone, but by every word that comes from the mouth of God.” (Mt 4:4)

This passage reminds us that the human being is indeed hungry—but not only physically. We are also spiritually hungry. When we try to fill that hunger with food (too much or too little), with diets, with protein, with obsessions, with numbers on a scale, we are trying to satisfy a deeper emptiness. And that emptiness can only be filled by God.

St. Augustine expressed it masterfully:

“You have made us for Yourself, O Lord, and our heart is restless until it rests in You.”


IV. The body as temple, not idol

Christianity does not despise the body. Quite the opposite: it recognizes the body as a temple of the Holy Spirit (1 Cor 6:19). Caring for it is an act of gratitude and responsibility. But care is not worship. It is not obsession. It is not salvation.

When the body becomes the absolute center of our attention, when our inner peace depends on what we eat or don’t eat, the weight we gain or lose, we have gone from treating the body as temple to worshipping it as idol.

And idolatry is, ultimately, a form of spiritual gluttony: trying to fill ourselves with something that is not God.


V. Disguised gluttony: when health becomes slavery

Today, many no longer fall into gluttony by overeating, but rather by seeking absolute control over what they eat. Orthorexia—the obsession with eating “healthily”—is a growing phenomenon. Social media is filled with influencers promoting extreme diets, perfect bodies, sinless food (no sugar, no gluten, no fat, no flavor…).

This obsession, though socially praised, can be spiritually dangerous:

  • It robs us of interior freedom.
  • It makes us judge others based on what they eat.
  • It leads to constant anxiety and guilt.
  • It steals our sense of gratitude and joy in ordinary things.

And above all, it places ourselves—our will, our body, our dietary plan—at the center. Instead of trusting in Providence, we try to save ourselves through diet.


VI. A theological and pastoral guide to living the virtue of balance

The virtue that opposes gluttony is not dieting—it is temperance: the capacity to use created goods rightly. To eat with order, gratitude, and freedom.

Below is a practical guide for living a Christian, ordered, and spiritual relationship with food:

1. Recover the sense of food as gift

Every meal is a gift from God. Blessing our meals, eating with family, avoiding haste—these are ways to redeem the act of eating.

“So whether you eat or drink, or whatever you do, do everything for the glory of God.” (1 Cor 10:31)

2. Don’t place your peace in a nutritional chart

Inner peace doesn’t come from calories, macros, or glycemic index. It comes from knowing you are loved by God—even with your imperfections, your extra weight, your past failures.

3. Live the virtue of temperance

It’s not about not enjoying—it’s about not being enslaved. Enjoying a dessert without guilt, or freely saying no to a craving, are signs of spiritual maturity.

4. Care for your body, but even more for your soul

Exercise, yes. Eat healthy, yes. But don’t forget to pray, read the Word, go to confession, love. Spiritual health is eternal; physical health is fleeting.

5. Do not judge others by their bodies or eating habits

The Christian gaze is compassionate. You never know what lies behind someone’s weight or extreme thinness. Charity begins at the table.

6. Recover fasting as a path to freedom, not punishment

Christian fasting is not about losing weight—it’s about uniting with Christ, ordering our desires, opening ourselves to others. It’s not punishment: it’s prayer with the body.


Conclusion: A new path to interior freedom

Gluttony hasn’t disappeared. It has only changed form. It is no longer just about overeating, but about over-controlling, fearing, idolizing. But the Gospel continues to offer a path to freedom.

Christ invites us to eat with gratitude, to fast with joy, to live in balance. To see our body as a temple of the Spirit, not a gym sculpture. To make every meal a daily Eucharist: thanksgiving, not idolatry.

Because in the end, true health—the one that brings peace, joy, and meaning—doesn’t come from clean eating, but from a clean heart.


📌 A final prayer for the spiritual journey through food:

Lord, grant me the grace to eat with gratitude, to fast with joy, and to live in freedom.
May my body be a temple, not an idol.
May I not seek salvation through my merits, but receive Your love as daily nourishment.
Amen.
