We live in a culture of contradictions when it comes to obesity.

We dismiss BMI as an outdated, harmful metric—despite its nearly 98% concordance with DEXA scans, the gold standard for body composition analysis.

We resist acknowledging that obesity is fundamentally an energy balance issue—despite understanding that appetite isn't a conscious choice. We point to thyroid dysfunction, menopause, or poor sleep as primary culprits — despite these factors being contributors, not drivers, of the obesity epidemic.

Why do we engage in this cognitive dissonance?

Because confronting these realities feels like assigning blame. And in our culture, blame is often experienced as moral judgment — as failure, as diminished worth.

But here’s what we’ve gotten wrong: obesity is not about blame.

I’ve never encountered a person living with obesity who hasn’t tried a thousand different approaches to manage their weight. Not one.

These are people who have counted calories, eliminated food groups, followed every trending diet, purchased gym memberships they used faithfully — until life intervened — and measured their self-worth in pounds lost and regained.

I’ve never met someone who simply didn’t care. Who didn’t try.

The narrative of laziness or lack of willpower collapses under the weight of lived experience. These are people who have demonstrated extraordinary persistence, resilience, and self-discipline — often for decades.

And yet, we persist in oversimplified narratives that fail to capture the biological realities and human complexities of obesity. We’ve created a false binary: either obesity is entirely about personal responsibility (cruel and inaccurate), or it’s entirely beyond individual influence (well-intentioned but equally problematic).

The truth is more nuanced — and, paradoxically, more hopeful.

Yes, obesity involves energy balance: calories consumed versus calories expended. But this mechanical framing tells us nothing about why some people feel driven to eat more, why their bodies resist caloric restriction, or why their metabolism seems to fight them every step of the way.

Appetite isn’t a choice. It’s a complex biological symphony — regulated by hormones like leptin and ghrelin, influenced by genetics, shaped by early life experience, modulated by stress and sleep, and conducted within a food environment engineered for overconsumption.

Acknowledging this isn’t making excuses — it’s facing reality.

Thyroid dysfunction, menopause, and sleep disturbances matter, but they’re usually supporting actors — not leads. A sluggish thyroid might explain 5–10 pounds of weight gain, not 50 or 100. Menopause shifts hormone patterns and makes weight maintenance harder, but it doesn’t suspend the laws of thermodynamics.

Understanding these distinctions doesn’t minimize anyone’s struggle. It helps us target our energy and interventions where they can actually make a difference.

Our relationship with BMI has become unnecessarily polarized.

Yes, BMI has limitations. It doesn’t differentiate muscle from fat, it may not account for ethnic variation, and it tells us nothing about behavior or metabolic health.

But dismissing it entirely is like discarding a thermometer because it doesn’t diagnose the cause of a fever.

Used appropriately, BMI offers population-level insight and valuable screening information. It correlates well with more sophisticated body composition tools. It predicts health risks at scale. These facts don’t erase nuance or individual variation — they offer a place to start, not a final verdict.

The fear seems to be that acknowledging BMI’s utility — or that energy balance matters — somehow invalidates the lived experience of people with obesity. But the opposite is true. When we understand the tools and the science clearly, we can use them more compassionately.

What would it look like to hold multiple truths at once?

We can acknowledge that energy balance drives weight change — while recognizing that appetite regulation is largely unconscious and shaped by biology, environment, and circumstance.

We can validate BMI as a useful screening tool — while understanding its limits and refusing to use it as a weapon.

We can admit that thyroid dysfunction, menopause, and sleep impact weight — without overstating their role or using them to deflect from more central drivers.

We can reject both moral blame and medical fatalism.

Instead, we can understand obesity as a complex interaction between biology, environment, psychology, and behavior — one that demands nuance, flexibility, and personalized care.

Perhaps most importantly, we must decouple understanding from blame.

Recognizing that someone’s persistent hunger is driven by dysregulated hormones doesn’t diminish their effort — it explains it.

Understanding that sustainable weight management must address biology doesn’t minimize the struggle — it honors it by pointing to more effective solutions.

The goal isn’t to make anyone feel ashamed of their body or their journey. The goal is to create space for honest, science-informed, and empathetic conversations — conversations that can lead to real progress.

When we stop fearing the science, we can use it more skillfully.
When we stop attacking tools, we can employ them more wisely.
When we stop resisting biological truths, we can start working with them.

Obesity is not about blame. It’s about biology, environment, and a web of factors largely beyond conscious control. But understanding those factors — truly understanding them — opens doors to better care, better outcomes, and greater compassion.

The humanity and the science aren’t in conflict. They are partners — and both are essential.
