Dieting is among the most significant risk factors for eating disorder development, particularly during adolescence, but across all life stages, while excessive exercise often emerges as a maintaining behavior within the disorder. Yet “diet and exercise” are synonymous with health across almost the entire spectrum of medicine, wellness, and cultural discourse.
When the very behaviors our culture equates with health can serve as pathways to serious illness, something fundamental has been misunderstood about what health actually means.
Consider some common scenarios. January arrives with its relentless parade of transformation promises, or you're preparing for a wedding, or summer approaches, and you notice the "beach body" messaging intensifying. The impulse makes sense: you care about your health, and everywhere you look, the solution appears to be the same. Eat less, move more, commit to discipline.
The question isn't whether people should care about their well-being. Health is not a moral obligation, but for those who choose to pursue it, the framework matters enormously. If conventional approaches carry such risk, how do we navigate developing a lifestyle that actually supports us? What does health look like when it's not defined by diet culture?
The answers require dismantling some deeply embedded cultural assumptions, but they also point toward something more sustainable than the cycle of restriction and compensation that characterizes both eating disorders and much of what passes for "wellness."
Why do weight and appearance tell us so little about health?
The fitness and diet industries have successfully convinced us that certain external measures—weight, clothing size, visible muscle definition, caloric intake—serve as reliable proxies for health. This conflation is both scientifically inaccurate and clinically dangerous.
Someone can maintain what has been deemed to be a “socially acceptable” body through severe restriction and still experience profound metabolic dysfunction, bone density loss, cardiovascular strain, and hormonal disruption. Conversely, individuals across the entire weight spectrum can demonstrate markers of good health such as strong cardiovascular capacity, robust immune function, and lower mortality rates.
At the Kahm Center, metabolic testing and body composition analysis provide insight into cellular health that has nothing to do with body shape or size. These tools measure things like resting metabolic rate, which indicates whether someone is receiving adequate energy to support basic physiological processes. They assess lean muscle mass and bone density, markers that reveal whether the body has the resources it needs to maintain structural integrity. When we examine health through these testing methods, it becomes immediately clear that BMI offers very little meaningful information about well-being.
This misunderstanding has real consequences. When individuals orient their entire sense of health around appearance-based goals, they develop a tolerance for—and eventually an inability to recognize—serious physiological harm. The person who feels virtuous about skipping meals or pushing through injury because they're pursuing "wellness" has lost access to the internal signals that would otherwise protect them.
How does dieting disrupt the body?
Dieting and rigid exercise protocols also actively disrupt the body's sophisticated regulatory mechanisms. Hunger and fullness cues become unreliable when someone has spent months or years overriding them with an external meal plan. The body begins to prioritize survival over other functions when it perceives a chronic energy deficit. Sleep may be disrupted, and mood becomes increasingly labile, particularly around food-related decisions or missed workouts.
This interoceptive disconnect is not a personal failure; it's the outcome of treating the body as an object to be managed rather than a system to be supported. The compulsive exerciser who can no longer distinguish between the body’s call to rest that follows joyful movement and the depleting exhaustion that signals overtraining has lost access to crucial information. The chronic dieter who experiences every physical sensation as either hunger to be suppressed or fullness to be feared no longer knows what it feels like to nourish themselves.
Recovery requires gradually rebuilding these connections, which means temporarily releasing the external rules that have been drowning out internal wisdom. This process is not comfortable. It requires tolerating significant uncertainty while the body recalibrates. For families observing this phase of treatment, it can create questions about whether recovery means giving up on “health” forever. Understanding that this is actually the foundation for sustainable wellbeing helps everyone involved resist the cultural pressure to reinstate restriction.
How do we learn to eat intuitively?
The alternative to diet culture's rigid prescriptions is not chaos or indifference. Intuitive eating and joyful movement are evidence-backed, structured approaches grounded in the understanding that bodies have the mechanisms for maintaining equilibrium when we stop interfering with them.
This doesn't mean every food choice will feel obvious or that movement will always be appealing. It means learning to navigate decisions based on how the body feels, what it needs for sustained energy, and what supports psychological well-being rather than following external rules about diet and exercise.
Someone practicing intuitive eating might notice that having protein at breakfast helps them maintain steadier energy through the morning. They might recognize that their body asks for different things depending on stress levels or activity. They learn to distinguish between physical hunger and emotional discomfort, not to ignore the latter but to address it with tools other than food restriction, binge eating, or a binge/purge cycle.
Movement becomes something pursued because it feels good in the body, supports sleep quality, or provides stress relief, not because it earns permission to eat or burns a specific number of calories.
This approach requires immense trust in a body that may have felt like an adversary. It requires patience during the period when regulatory systems are still finding their baseline. It also requires opting out of the constant cultural commentary about what constitutes appropriate eating or exercise.
How do we define health on our own terms?
If January intentions aren't going to focus on weight loss or fitness goals, what might they address instead? Recovery-oriented goal-setting centers the internal experience rather than external measures. This might mean prioritizing connection with friends and family members, recognizing that eating disorder behaviors often thrive in isolation. It could involve developing creative practices that provide satisfaction and accomplishment outside the body. Rest might become a genuine priority, particularly for individuals whose relationship with productivity has been tangled up with their relationship with food and exercise.
The radical act here is not rejecting health, but refusing to let diet culture define it for you or complicate recovery as you work to rebuild your relationship with food and movement. When well-being is measured by how you feel in your body rather than how your body appears, that’s when sustainable health becomes possible.
