The Lies and Harm of Diet Culture


In a world filled with images of "perfect" bodies and endless streams of diet advice, it’s easy to feel like you’re not enough. The pressure to fit into these unrealistic beauty standards can be overwhelming, leaving you constantly unhappy with your body.


But here’s the truth: diet culture isn’t on your side. The media, magazines, and social media are all designed to make you feel inadequate so you’ll keep buying their products and services that promise to 'fix you.'


 

What is Diet Culture?


You've probably heard the term, maybe even used it, but you're not quite sure what it means. Diet culture is a system of beliefs that values thinness above all else—more than your personality, your spirit, and your thoughts.


This toxic system equates thinness with health, leading to the marginalization of people with larger bodies. Simply put, diet culture says thin = good and fat = bad.


Christy Harrison, a prominent anti-diet dietitian, defines diet culture as a system of beliefs that:


  • Worships thinness and equates it to health and moral virtue

  • Promotes weight loss as a means of attaining higher status

  • Demonizes certain ways of eating while elevating others,

  • Oppresses people who don't match up with its supposed picture of “health


This system of beliefs shows up everywhere: schools, media, homes, sports teams, and sometimes in unsuspecting places like churches and yoga studios. It feels like diet culture (this way of thinking about our bodies, food, and health) has permeated into every crevice it can.


Becoming aware of the lies diet culture sells you, which I explore in this post, is one of the first steps to shifting your beliefs.



 


 

Debunking the Myths: 10 Lies Perpetuated by Diet Culture


*All statements in bold are LIES. They are not my beliefs.


1. Body size is an indicator of health


Just because someone is thin doesn’t mean they’re healthy, and just because someone is large doesn’t mean they’re unhealthy.


Health includes physical, mental, and emotional well-being. Plenty of people with larger bodies have great health markers, while plenty of thin folks struggle with hidden health issues.



 

2. Being thin solves all your problems


Ever think losing those last 10 pounds will finally make you feel good in your skin? Unfortunately, weight loss doesn’t fix deeper issues.


On some level, you know happiness can’t be bought or achieved solely through physical appearance, but it's easy to convince ourselves otherwise. On the contrary, chasing thinness can lead to UN-happiness, and is linked to anxiety and obsession with food and body image.




 

3. Your size is a reflection of your worth as a human


Diet culture might make you think that looking a certain way makes you more lovable, but that’s simply not true.


Size discrimination and anti-fatness are cruel acts that have the potential to affect how you see yourself or navigate the world, but they don’t determine your worth.


How others treat you based on your weight does not reflect your value as a human being. Everyone deserves respect and dignity, regardless of their size.

 

4. You have full control of the shape of your body

Diet culture teaches that eating certain foods and exercising a certain amount will sculpt your body into the exact shape you want it to be.


Except… WRONG.


Genetics, medication, metabolism, and age all play significant roles in how weight is distributed across your body. Total control over your body’s shape is an illusion.


 

5. Food is either 'good' or 'bad'


Assigning morality to food is a diet culture lie. Food is inherently neutral.


Does this sound familiar? “Oh, I’ve been so bad today! I shouldn’t have eaten all those [insert food].”


Eating certain foods doesn’t make you “bad.” Food shouldn't evoke punishment, reward, guilt, or praise. Viewing food as neutral helps break the cycle of shame and guilt around eating.


 

6. You need to stop or reverse the aging process


Aging. is. natural.


Any serum, cream, or juice blend claiming to stop this natural process is either unnatural or lying. Embrace aging as a beautiful part of life. Wrinkles and grey hair are signs of a life well-lived, filled with experiences and wisdom.


 

7. Dieting is the path to health


Most diets are unsustainable and can lead to yo-yo dieting and disordered eating which take a toll on your body and health.


Research shows that long-term health is better supported by intuitive eating. Focusing on nourishment and body trust rather than restriction can lead to a more positive relationship with food and your body.




 

8. Detoxes and cleanses are necessary for good health


Diet culture often promotes detoxes and cleanses as essential for good health. In reality, your body already has a sophisticated system for detoxifying itself. The liver, kidneys, and other organs work continuously to eliminate toxins.


 

9. Feeling ashamed of your body or perpetually insecure is normal


It's common to bond over insecurities, comparing our so-called ‘inadequacies.’ Diet culture convinces you that everyone hates their body, making you think your struggles are par for the course.


But this isn’t the way it has to be. Some people are comfortable with their weight and proud of their appearance. Seeking support and practicing self-compassion can help you break free from these harmful beliefs. Embracing your body just might inspire others to do the same.



 

10. If you’re not losing weight, you’re not trying hard enough.


Diet culture blames you for not losing weight, but in reality, diets often fail, and your body may already be at its healthy weight. The problem lies with the unrealistic expectations of diet culture, not with you.


Understanding that weight loss is not a measure of effort or success can help free you from this damaging mindset.


 

Moving Beyond Diet Culture


Breaking away from diet culture’s toxic grip is a process of questioning old beliefs, pushing back against societal norms, and realizing that your worth isn’t tied to what you see in the mirror or a number on a scale.


As you work through this, be kind to yourself. Surround yourself with people who love and support you for who you are, not how you look (bonus points if they're also pushing back against diet culture in their own lives). Most importantly, focus on building a relationship with food and your body that’s rooted in respect and love—not guilt or shame.


Diet culture feeds off insecurity, but you’ve got the power to break that cycle. By spotting and rejecting these harmful myths, you can start living a life that’s true to who you are, filled with self-compassion and authenticity. Remember, you are enough just as you are—always have been, always will be.
