As a registered dietitian working extensively with athletes and health-conscious individuals across the UK, I’ve observed that true wellness extends far beyond nutrition alone. The most successful transformations occur when we address our mental wellbeing alongside our physical health. Drawing from evidence-based practice, here’s how to create a comprehensive approach to improving your life.

Creating Boundaries: The Foundation of Wellbeing

Research from the University of Cambridge demonstrates that toxic relationships significantly impact our stress hormones, particularly cortisol levels, which can disrupt metabolism and appetite regulation. As the sport dietitian in my practice, I’ve witnessed how negative relationships directly correlate with poor eating behaviours and reduced motivation for physical activity.

Removing toxic influences isn’t about being harsh — it’s about creating space for growth. Start by identifying relationships that consistently drain your energy or undermine your goals. The British Psychological Society suggests implementing the “energy audit” technique: after each interaction, assess whether you feel energised or depleted. Gradually reduce contact with energy-draining individuals whilst strengthening connections with supportive people.

Cultivating Kindness: The Ripple Effect

Practising kindness, both towards others and yourself, creates measurable physiological benefits. Studies published in the Journal of Health Psychology show that acts of kindness increase oxytocin levels, which can lower blood pressure and reduce inflammation — factors crucial for optimal athletic performance and general health.

The sport dietitian approach I recommend involves incorporating daily acts of kindness into your routine. This might include complimenting a colleague, volunteering for a local charity, or simply practising self-compassion when you miss a workout or indulge in less nutritious foods.

Building Self-Esteem Through Evidence-Based Strategies

Low self-esteem often manifests as emotional eating patterns and avoidance of physical activity. Research from King’s College London indicates that cognitive behavioural techniques can significantly improve self-worth and subsequent health behaviours.

Implement daily affirmations based on your achievements rather than appearance. Keep a “wins journal” documenting small victories, whether completing a challenging workout or choosing a nutritious meal. As the sport dietitian working with diverse populations, I’ve observed that self-esteem improvements often precede sustainable dietary changes.

Practical Nutrition: Vegetable Integration and Portion Control

The NHS recommends five portions of fruits and vegetables daily, yet most UK adults consume fewer than three. The key lies in strategic integration rather than dramatic overhauls. Begin by adding vegetables to existing meals: spinach in smoothies, grated carrots in pasta sauces, or roasted vegetables as pizza toppings.

For portion control, utilise the “plate method”: fill half your plate with vegetables, one quarter with lean protein, and one quarter with complex carbohydrates. This visual approach, endorsed by Diabetes UK, simplifies portion management without requiring scales or calorie counting.

The sport dietitian methodology I employ focuses on nutrient density rather than restriction. Choose colourful vegetables to maximise antioxidant intake — compounds essential for recovery and immune function.

Habit Stacking for Increased Activity

Professor BJ Fogg’s research at Stanford University demonstrates that linking new behaviours to established routines creates lasting change. Apply this “habit stacking” principle to increase daily movement.

Examples include:

• After brewing your morning tea, perform ten squats
• Following each bathroom break, walk around your home or office
• Before watching evening television, complete a five-minute stretch routine

The sport dietitian approach emphasises that small, consistent actions compound over time. Aim for an additional 2,000 steps daily through habit stacking — this modest increase can improve cardiovascular health and mental wellbeing according to research from the University of Edinburgh.

Conclusion

Sustainable wellness requires addressing mental health alongside physical habits. By removing toxic influences, practising kindness, building self-esteem, incorporating vegetables strategically, and using habit stacking for increased movement, you create a comprehensive foundation for lasting change.

Remember, transformation is a gradual process. Focus on implementing one strategy at a time, allowing each to become established before adding the next. This patient, evidence-based approach yields the most sustainable results.
