A strong concern with healthy eating, leading in some cases to extreme anxiety about and obsession with food. Usually plays out as calorie and nutrient tracking, and rigid and restrictive eating patterns.

Discussion

Orthorexia is a relatively new concept, and as you might guess from the name, it’s related to anorexia. Both are about controlling and restricting eating, but they do so in different ways.

• Anorexia (an = without, orexia = desire) is a reduction of eating below the amount needed to survive, and sometimes not eating anything at all.
• Orthorexia (ortho = correct, proper, regular, + orexia = desire), reduction and restriction of eating with the goal of eating “properly” and “being healthy.”

Wanting to be healthy and eat better isn’t necessarily a problem, of course, but as with everything, it’s possible to take it too far. For some people, trying to limit processed foods, preservatives, and added salt/sugar becomes obsessive, and causes them excessive worry and anxiety about the state of their health and diet: worries which interfere with their ability to function in day-to-day life.

The natural assumption would be to associate orthorexia with “restrictive” eating habits like vegetarianism and veganism, but this appears not to be the case (Işık and Şahin 2026). There does seem to be a connection with social media use, and specifically, the more health and diet-related content you consume, the more orthorexic your thinking becomes (Nakhl et al. 2026).

Subjectivity

An interesting point to note is that what we mean by “healthy” is entirely subjective and often fad-based. The current (Nov. 2026) cultural obsession with maxxing protein is a perfect example of this. Many people have become obsessed with eating as much protein as possible, even though there is no biological reason to do so. “Health” is the rationalisation given for this form of orthorexia, but the motivation is emotional: fear of not living up to unhealthy beauty standards leading to body dysmorphia.

This is an example of the idea that most psychological “disorders” are actually symptoms of deeper emotional problems. Instead of being a “mental disease,” we can interpret orthorexia as desires and actions that manage powerful fears and anxieties. In this case, orthorexic eating manages our insecurity about body shape, size, and sexual attractiveness. These fears connect to a deep fear of social rejection, and ridicule; which is the itself result of the yet deeper feeling that love is conditional and that we have to be “good” in order to receive the love we crave.

“Good”, of course, is also subjective, and so we can attach the word to any socially determined symbol of “goodness,” even if that means trying so hard to be “healthy” that you make yourself ill. This is how and why diet fads can swing so wildly from one extreme to another: “good” and “healthy” aren’t actually connected to the physical reality of our real dietary needs.

And so in my view, the chain for orthorexia goes something like this:

1. I need to be ‘good’ to receive love.
2. Being ‘healthy’ makes me ‘good,’ so I must be healthy to be lovable.
3. To be healthy, I need to eat properly.
4. To eat properly, I need to monitor my diet and track my calories.
5. If I don’t track myself very carefully, I might make mistakes and become ‘unhealthy’ (and therefore unlovable) without realising.
6. I have to plan my diet perfectly and monitor myself all the time, so that I never make a dietary mistake.
7. If I stop worrying about my diet for even a minute, I will become unhealthy.

Quotes

Orthorexia nervosa (ON) is a newly described mental disorder characterized by an extreme obsession with the consumption of healthy foods, resulting in anxiety and impaired functionality. (Nakhl et al. 2026)

This heightened anxiety is related to the patient’s food choices, where distress occurs when deviations from the strictly laid out dietary rules are made, leading to multiple severe nutritional deficiencies as well as social withdrawal and impaired functioning, leading to decreased quality of life. (Nakhl et al. 2026)

anorexia(n.): 1590s, “morbid want of appetite,” Modern Latin, from Greek anorexia, from an- “without” (see an- (1)) + orexis “appetite, desire,” from oregein “to desire, long for,” literally “reach out (one’s hand), stretch oneself, stretch out for” (from PIE root *reg- “move in a straight line”) + abstract noun ending -ia. In current use, often short for anorexia nervosa. (Etymonline)

ortho-: word-forming element meaning “straight, upright, rectangular, regular; true, correct, proper,” now mostly in scientific and technical compounds, from Greek orthos “straight, true, correct, regular,” from PIE *eredh- “high” (source also of Sanskrit urdhvah “high, lofty, steep,” Latin arduus “high, steep,” Old Irish ard “high”). (Etymonline)
