Nutritional Psychology
What is Nutritional Psychology?
Nutritional Psychology (NP) is the field of how cognitive choices influence nutrition, psychological health, and overall health. Nutritional Psychology is an emerging, evidence-based field that looks at the relationship between diet, mental health, and emotional well-being. It explores how food influences mood, energy, cognition, and resilience — and how nutritional choices can support recovery from mental health difficulties.
Rather than replacing therapy or medical treatment, Nutritional Psychology provides a complementary approach, helping you build awareness of the food–mood connection and make changes that benefit both body and mind.

What role does psychology play in weight management?
Well let me ask you this; do you often find yourself eating when you’re not actually hungry? Or do you use food as a source of comfort when you’re feeling depressed, sad, anxious, or bored? Most people don’t realise the extent to which our feelings can impact our eating habits. An occasional binge may seem harmless, but emotional eating can escalate into serious health and weight issues, and can become very difficult to control. Most weight loss programs focus on diet and exercise but they often overlook what is the most potent weight loss weapon: your mind! Understanding the connections between your thoughts, emotions and your eating patterns and behaviours, will start to reveal some important insights necessary to manage your weight effectively.
Becoming aware that emotional eating and binge eating may be a major contributor to your weight issues is a great start. If this is the case, you now need to find constructive ways to cope with your issues in ways that don’t involve seeking comfort through food, if you want to achieve long-term results.
Research and evidence clearly shows that no matter what your weight is; diets and deprivation actually make you hungry and create powerful cravings for the very foods you are trying to avoid! Diets also do not address the causes and triggers of emotional eating, and the psychological components of the eating behaviours leading to weight issues.
There are so many scientifically proven connections between emotional stress, digestion, metabolism, weight, and health. Research highlights an association between adverse life experiences and the subsequent development of obesity or being overweight. Research has also shown that chronic depression and anxiety tend to cause emotional eating, and people experiencing these emotional states are especially prone to crave sweet and fatty foods.
Research has also demonstrated the association between childhood trauma and overweight and obesity in young adults: the mediating role of food addiction. Deeper emotional issues and past traumas can also be underlying reasons for weight gain. Unconsciously, a layer of fat on the body may serve to prevent other people from getting too close. People can often harbor unresolved issues well into midlife and beyond, and unconsciously strive to remain “fat-protected” and as a result future weight loss efforts can seem futile. Most experts agree that overeating and weight gain is a stress-induced response that directly affects your hormones and your metabolism.
So, it is imperative to understand and improve your emotional and psychological relationship with food, and to realise the impact this has upon your weight management if you struggle with:

The Evidence for Nutritional Psychology
Research strongly supports the link between nutrition and mental health:
- A landmark Australian trial (SMILES, 2017) showed a Mediterranean-style diet significantly reduced depression symptoms compared with social support alone.
- A 2023 systematic review & meta-analysis of randomized controlled trials supported that a Mediterranean-style diet reduces depressive symptoms in adults.
- 2023–2024 longitudinal data supports that diet quality improves depressive symptom recurrence and prevention.
- A 2020 meta-analysis confirmed dietary improvement leads to reduced symptoms of depression across diverse populations.
- Nutritional psychology is increasingly recognised by mental health professionals as a valuable adjunct to therapy.
- Accumulating evidence provides support for the existence of direct relationships between nutrition, stress susceptibility, mental health and mental function throughout the lifespan.
