Welcome to Episode 44 of The Mood Booster Podcast. This episode follows directly from our very first live workshop, Joyful Fuelling for Your New Years Fitness Goals, where we sat in a room with James from BrashNutrition and unpacked the realities of diet culture, misinformation, and the pressure to change our bodies in the name of health. 

In this conversation, we reflect more deeply on one central question: why do we diet in the first place. Is it really about health, or is it about chasing unrealistic body ideals shaped by culture, stigma, and misinformation? 

We explore how diet culture has evolved across history, how thinness became moralised and medicalised, and why body image is so often the hidden driver behind food choices. Drawing on psychology, nutrition science, and lived experience, Dr Marcus breaks down why most diets fail, not because people lack willpower, but because restriction, hyper fixation, and fear-based motivation actively work against us. 

We talk openly about our own early relationships with food, fitness, and online health content, and how misinformation thrives by exploiting insecurity and urgency. We also unpack the psychological mechanisms behind dieting behaviour, including decision fatigue, cognitive restraint, and why the more we focus on food rules, the worse our relationship with food often becomes. 

This is an honest, compassionate, and grounding episode for anyone who feels stuck in cycles of restriction, confusion, or body dissatisfaction. It is not about telling you what to eat, but about helping you understand why diet culture keeps pulling you back in, and how decentring diet can be a powerful step toward both wellbeing and performance. 

🎧 In this episode, we reflect on 

  • Why body image is often the true driver behind dieting 
  • How diet culture shapes what we believe health should look like 
  • The historical and social roots of weight stigma 
  • Why thinness does not equal health or fitness 
  • How misinformation spreads through fear and reductionist thinking 
  • Why most diets fail from a psychological perspective 
  • The difference between a diet and your diet 
  • Decision fatigue, hyper fixation, and restrictive cycles 
  • What it means to decentre food and body control 
  • Why fuelling should be context specific, not aesthetic driven 

    • 🛠 Practical Advice for Listeners 

    • Question whether your goal is about health or appearance 
    • Notice fear-based messaging in nutrition content 
    • Shift focus from restriction to addition 
    • Reduce food rules and moral language around eating 
    • Fuel training for function, not punishment 
    • Remember that confusion is not failure, it is a product of the environment 

      • This episode is about reclaiming autonomy, reducing shame, and understanding that wanting to feel fit or well does not require hating your body or micromanaging food. It is about creating space for balance, joy, and sustainability.
