DO WE SMELL WITH OUR EYES? FAT BIAS, ODOR, AND THE POWER OF PERCEPTION
DO WE SMELL WITH OUR EYES? FAT BIAS, ODOR, AND THE POWER OF PERCEPTION
By Dr. Shamil
Editor’s Note:
This is Part Two in a series exploring the relationship between body weight and body odor. In Part One, I broke down the scientific and physiological reasons why fat people are more prone to body odor, and shared practical strategies for managing it.
The idea for this second piece came after a recent experience:
After a two-week visit with family in London, I boarded a flight from Heathrow to JFK, settling into my seat when a fat man came to sit beside me. My initial concern was his potential body odor, worrying it might make the eight-hour flight unpleasant and uncomfortable. Unfortunately, my fears were confirmed—he did have a noticeable smell, though not as overpowering as I’d anticipated. This experience sparked introspection: was my reaction driven by physical reality or subconscious bias? It prompted me to explore the psychological aspects of why we often associate body odor with fat people.
In this follow-up, we go beyond biology to examine the social and psychological dimensions—specifically how visual bias affects how we perceive scent.

Introduction
Let me begin this second installment the same way I began the first: There is nothing inherently wrong with the word fat.
It’s a descriptor—just like “tall,” “short,” or “curly-haired.” Reclaiming the word fat means refusing to tiptoe around the truth, while also rejecting shame and stigma. When used responsibly, it can serve as a neutral, even empowering, starting point for deeper discussions—like this one—on body odor, public perception, and overall well-being.
In Part One of this series, I explained the scientific reasons why people with obesity are more prone to bad body odor:
• Increased sweat production
• Warm, bacteria-friendly skin folds
• Trapped moisture in areas with poor ventilation
That article was about biology. This article is about bias.

We Smell With Our Eyes
Yes, body odor is real. But so is the perception of odor, and that’s a different beast altogether.
We think we smell people—but often, we’re judging them visually. In psychological terms, this is called “olfactory bias influenced by visual cues.” Simply put: we often assume someone smells bad just because they look overweight.
This is a phenomenon known as “visual-olfactory cross-modal association”: we form multisensory impressions of others based on a blend of cues—not just what we actually smell, but what we expect to smell.
A fat person might be perfectly clean, freshly showered, and wearing a lovely fragrance—
Yet, in the eyes of a biased observer, they are already “smelly.”
This is not a conscious act of malice. It’s a subconscious cognitive shortcut, part of a broader societal conditioning where fatness has long been unfairly associated with laziness, poor hygiene, and lack of self-care.

The “Smelly Fat Person” Trope
From cartoons to sitcoms, the image of the “smelly fat guy” has been played for laughs for decades. These portrayals reinforce implicit bias, making people more likely to associate larger bodies with foul odor, even when none is present.
This is a classic example of the “horns effect”—a cognitive bias where one perceived negative trait (such as obesity) leads to assumptions about other unrelated negative traits (such as poor hygiene, bad smell, low intelligence, etc.).

It’s not just unfair. It’s unhealthy.
When a person is consistently viewed through a lens of disgust, it chips away at their self-esteem, which can discourage self-care behaviors—ironically reinforcing the very stereotypes they’re trying to avoid.

Smelling Better Physically — and Perceptually
As we discussed in the first article, there are clear steps overweight individuals can take to smell physically better:
• Better hygiene and cleansing of sweat-prone areas
• Use of citric acid (like lemon) or antiperspirants
• Regular laundering of clothes
• Cooling sprays to reduce bacterial activity
But what about perceptual smell? How do you tackle something that lives in other people’s minds?
Here’s where we shift the conversation to self-transformation—not for validation, but for liberation.

When You Lose Weight, Perception Changes
Let’s be candid: when you lose weight, people treat you differently.
It’s not always fair—but it’s true. You become less likely to be seen as lazy, sloppy, or smelly. Whether or not those things were ever true, your visual cues begin to match society’s ideal of health, and that alone changes how you’re perceived—including how you’re smelled.
This doesn’t mean you have to lose weight to be worthy. But if you’re looking to:
• Improve your cardiovascular health
• Lower your blood pressure or risk of diabetes
• Move through life with greater ease and confidence
• And yes, challenge the perception that you smell
—then losing excess weight can be part of a holistic wellness journey.
⸻
And Yet, Compassion Must Remain
Some people are fat due to genetic, hormonal, or medical reasons—and to them, this article is not a condemnation, but a call to self-care on one’s own terms.
Well-being does not begin with a dress size. It begins with self-respect.
Whether or not weight loss is accessible or realistic for you, there are still tools you can use—from smart hygiene practices to wardrobe hacks to scent layering—to improve how you feel and how you’re perceived.
This is not fat-shaming. This is life-enhancing.
This is self-empowerment.
This is health-forward thinking.
⸻
Final Thoughts: Biology Meets Bias
In the end, fat people may smell more for biological reasons—but they also smell worse in people’s minds because of cultural conditioning.
By understanding both, you unlock a powerful dual strategy:
1. Improve physical scent with hygiene and wellness
2. Reduce perceptual stigma by taking ownership of your health journey—including weight, if that’s possible for you
Smell, like beauty, is as much about perception as it is about chemistry.
And you have more control over both than you think.
