Diet culture and its harms

It's hard to escape messages that thinner is better, that some foods are "clean" and others are "cheating", and that willpower alone should fix our bodies. This is diet culture, and it can quietly wear down our mental health.

What it is

Diet culture is the widespread set of beliefs that values thinness, appearance and weight loss above health, wellbeing and self-acceptance. It shows up in advertising, social media, workplace conversations and even well-meaning family comments. Diet culture often disguises itself as "health advice", but its real focus is usually appearance and control, not genuine wellbeing.

Signs to notice

• Feeling like your worth changes depending on your weight or what you ate that day
• Constant cycles of restrictive eating followed by periods of "giving in"
• Moral language around food - feeling "good" or "bad" after eating
• Chasing quick-fix diets or detoxes that promise fast results
• Spending significant time, money or mental energy trying to shrink your body
• Feeling anxious or excluded in situations involving food

What helps

• Notice diet messaging when it appears, and remind yourself it is designed to sell products, not to support your wellbeing.
• Shift the goal from weight loss to how you actually feel - energy, sleep, mood, strength and digestion are more useful measures.
• Build meals around variety and enjoyment rather than restriction. All foods can have a place.
• Practise listening to hunger and fullness cues instead of following rigid external rules.
• Talk back to diet culture thoughts. If you catch yourself thinking "I was bad today", try reframing to "I ate in a way that didn't feel great, and that's okay, I can eat well at the next meal."
• Choose movement you enjoy, for the way it makes you feel, rather than as punishment for eating.
• Surround yourself, where you can, with people and content that support body respect rather than body criticism.

When to reach out for help

If diet culture messages have tipped into ongoing anxiety about food, frequent restrictive eating, bingeing, or if your mood and self-esteem are consistently tied to eating or weight, it may help to speak with a professional. This is especially important if these patterns are affecting your physical health, relationships or ability to concentrate at work. A professional can assess your relationship with food and support you in building a more sustainable approach.
