Top 5 Food Beliefs That Hold You Back (and What to Replace Them With)

Food beliefs shape how we eat, how we move, and how we feel about our bodies. They show up in our grocery carts, our lunch breaks, our cultures, and our inner dialogues. And while some of these beliefs might feel like common sense, many are rooted not in actual health science, but in diet culture, MLM marketing tactics, or straight-up misinformation.

If you've ever blamed yourself for “falling off the wagon,” worried about carbs after a Beachbody challenge, or tried to make up for a slice of cake with celery juice, this post is for you.

Let’s dismantle five of the most common food beliefs that keep people stuck in cycles of shame, restriction, and rebound and explore what to believe instead.

1. “Carbs make you fat.”

This one is the granddaddy of diet myths. Whether it crept in through Atkins, keto influencers, or a Beachbody rep pushing asphalt flavored shake mixes, the belief that carbohydrates inherently cause fat gain is not just false, it’s actively harmful.

The truth: Carbohydrates are your body's preferred energy source. They're critical for brain function, hormone regulation, and daily movement. The human body runs more efficiently when it's fueled adequately, and carbs are a big part of that equation. Multiple controlled feeding studies show that weight gain results from a sustained caloric surplus, not from eating carbs (or any single nutrient) alone.

The fear of carbs isn’t just a misunderstanding, it’s a symptom of diet culture’s obsession with restriction. Diet culture perpetuates the idea that thinness equals worthiness and that the pursuit of it must involve suffering. Carbs are often one of the first things demonized because they’re everywhere, and they’re easy to cut.

What to believe instead: Carbs are fuel, not the enemy. The type of carbohydrates consumed matters; whole grains, fruits, and vegetables are preferable for overall health. Including a variety of complex carbs like oats, potatoes, rice, and whole grain bread alongside protein sources and healthy fats will ensure you’re eating a balanced diet. If you’ve been restricting, you may initially crave more of them, and that’s normal. Over time, your body finds its rhythm.

2. “I need to detox after eating 'bad' foods.”

Thanks to Multi-Level Marketing Companies (MLMs) like Arbonne, Modere, and It Works!, the term “detox” has been hijacked and slapped on overpriced powders, teas, and supplement kits promising to fix the “damage” done by an indulgent weekend or a holiday meal.

The truth: Your liver and kidneys are detoxing your body 24/7. No supplement can do it better. In fact, supplement use is responsible for 20% of liver injury cases in the United States. What these products often do is induce short-term water loss, laxative effects, or appetite suppression, all of which are temporary and can be dangerous if used chronically.

The detox narrative reinforces the harmful cycle of moralizing food: clean vs. dirty, pure vs. toxic, worthy vs. indulgent. This is classic diet culture messaging, and it has real consequences. Constantly chasing “clean” eating can lead to orthorexic patterns, nutrient gaps, and even full-blown eating disorders.

What to believe instead: One meal doesn’t wreck your health. Your body is wildly resilient when it comes to managing calories . If you’re feeling off after a big night out, the best approach is to rehydrate, get some rest, and move on. No powder required.

3. “Skipping meals helps me lose weight faster.”

Meal skipping has been repackaged as productivity, especially in hustle culture and intermittent fasting circles. But for most people, especially women and folks with a history of disordered eating, skipping meals is more likely to trigger metabolic stress than results. The timing of meals matters less than the overall quality and quantity of what is eaten.

The truth: Regularly skipping meals can disrupt your hunger cues, potentially leading to digestive and kidney diseases, lead to blood sugar crashes, and spike cravings that make you feel “out of control” later. It’s associated with poorer diet quality and metabolic health outcomes over time. Maintaining a proper diet and healthy diet with regular meals is important for overall well-being and nutrition.

Diet culture celebrates restraint and equates hunger with virtue. This leads many people to ignore hunger until it becomes urgent, then blame themselves for overeating when their body finally fights back.

What to believe instead: Eating at regular intervals, about every 3 to 5 hours, is a solid foundation for blood sugar stability, energy, and hormone regulation. Combining regular meals with physical activity supports a healthy lifestyle and helps avoid the pitfalls of restrictive diets that often exclude other foods and compromise nutrition. There’s no medal for being hangry.

4. “Healthy eating means clean eating.”

“Clean eating” is a vague, unregulated term that sounds wholesome but often masks a deeply restrictive mindset. MLM coaches and Instagram wellness influencers use it to sell everything from juice resets to coaching memberships, often with the implied promise of transformation.

The truth: There is no standardized definition of “clean eating,” and most interpretations exclude foods unnecessarily. Research supports eating patterns that are high in fiber, rich in plant diversity, and include cultural and personal preferences, not rigid purity standards.

Clean eating often feeds into orthorexia, a type of disordered eating characterized by obsessive focus on food purity. It’s easy to slide from “trying to eat well” into anxious food avoidance, especially when social media praises willpower over wellbeing.

What to believe instead: Flexibility and adequacy matter more than purity. A nourishing plate can include frozen meals, protein bars, fast food, or snacks from the gas station. It’s about the big picture, not individual ingredients.

5. “If I eat intuitively, I’ll never stop eating 'junk.'”

Diet culture tells us we can’t trust our bodies. That without rigid rules, we’ll spiral into chaos. So when people hear about intuitive eating, they often panic: “But what if I just eat cookies forever?”

The truth: That fear is a direct result of chronic restriction. When you’ve been denying yourself certain foods, it makes sense that you’d want more of them when they’re finally allowed. But this isn’t a sign of failure, it’s part of the healing process. Intuitive eating supports well-being and nutrition by encouraging a variety of food choices, including whole foods, fruit, vegetables, and other foods, allowing for a balanced and flexible approach to eating. And the research backs it up: intuitive eating is associated with less disordered eating, better body image, and more stable long-term health markers.

Eventually, the novelty wears off. When no food is off-limits, food loses its emotional charge. You start to notice how different foods make you feel, and your choices become guided by internal cues, not external rules.

What to believe instead: Your body can be trusted. It may take time to reconnect with your hunger and fullness cues, especially after years of dieting. But intuitive eating is a learnable skill, and it works. Including a range of whole foods and nourishing meals can further support your overall well-being.

Final Thoughts

Diet culture is loud, persuasive, and profitable. It makes billions every year by convincing you that you’re broken, and selling you the fix. But you are not broken. You do not need to detox, restrict, or earn your food through exercise or suffering.

And you are absolutely allowed to let go of beliefs that no longer serve you, even if they came from a coach you used to admire, a plan that “worked” for a while, or an influencer who seemed trustworthy.

Your relationship with food is personal, nuanced, and worthy of care. When we stop letting diet culture drive our choices, we make space for real, lasting wellness, the kind that doesn’t hinge on rules, but on respect.
