At our clinic, we work closely with individuals experiencing treatment-resistant depression—those who have not found sufficient relief from standard treatments such as antidepressant medications. While our focus is on providing advanced, evidence-based treatments like Transcranial Magnetic Stimulation (TMS), we also recognise the value of supporting mental health through lifestyle and self-care strategies.
One important area to consider is nutrition. While dietary changes are not a replacement for medical or psychiatric treatment, there is growing evidence that what we eat can influence our brain health and emotional wellbeing.
Considering the Role of Diet in Mental Health
Depression is complex, and no single cause or solution applies to everyone. However, food choices may interact with biological factors such as inflammation, gut health, and nutrient availability, all of which can affect mood regulation. Even modest improvements in diet may have a positive impact over time, particularly when integrated into a broader, holistic approach to care.
Foods and Substances That May Affect Mood
Everyone responds differently, but some dietary substances have been linked to mood fluctuations or may contribute to symptoms such as anxiety, fatigue, or irritability. These include:
Caffeine
Commonly found in coffee, tea, energy drinks, chocolate, and some medications, caffeine is a stimulant that can increase alertness in the short term. However, for individuals prone to anxiety or sleep issues, it may contribute to restlessness, low mood, or disrupted sleep cycles.
Salt (Sodium)
High sodium intake, particularly from processed and packaged foods, can affect fluid balance, blood pressure, and even sleep quality. These factors may indirectly impact emotional wellbeing.
Refined Sugar
Frequent consumption of added sugars (such as those in sweet drinks, baked goods, or confectionery) may lead to blood sugar fluctuations, which can influence mood and energy. Some research has suggested a potential link between high sugar intake and increased risk of depressive symptoms, although more studies are needed.
Preservatives and Hormones in Processed Foods
Highly processed foods, particularly some meats, may contain added preservatives or hormones. While the exact effects on mental health are still being explored, some individuals report feeling better when they reduce processed food intake and choose whole, nutrient-dense options.
Alcohol and Nicotine
These substances are often used to cope with distress, but they can negatively affect mood regulation and sleep over time. Nicotine is a stimulant, while alcohol is a depressant—both can contribute to mood instability and may interfere with recovery.
Nutritional Deficiencies and Mental Health
It’s not only what’s consumed, but also what may be missing. Low levels of key nutrients—such as B vitamins, iron, magnesium, omega-3 fatty acids, and vitamin D—have been associated with mood-related symptoms in some individuals. Dehydration and low fibre intake can also affect overall wellbeing.
If you’re concerned about nutritional gaps, speaking with your GP or an accredited dietitian can help clarify whether further investigation or support is needed.
The Mediterranean Diet: A Pattern Worth Considering
One dietary pattern that has shown potential benefits for mental health in some studies is the Mediterranean diet. This way of eating is rich in whole, unprocessed foods and healthy fats, and it may support brain and gut health through reduced inflammation and improved nutrient intake.
Common features of the Mediterranean diet include:
Leafy greens and colourful vegetables
Whole fruits, especially berries
Nuts and seeds
Legumes (such as lentils, chickpeas, and beans)
Whole grains
Fish and seafood
Poultry in moderation
Extra virgin olive oil
Herbs and spices
Limited amounts of red wine (optional and only if safe and appropriate)
While it is not a treatment in itself, adopting a Mediterranean-style eating pattern may complement other treatments and support overall health.
A Holistic Approach to Treatment-Resistant Depression
For individuals exploring TMS as an option for treatment-resistant depression, it can be helpful to view recovery as a multi-faceted process. While TMS targets specific areas of brain function, diet, sleep, movement, and social support all contribute to how a person feels day to day.
Improving your diet doesn’t require drastic changes. Starting with small, realistic adjustments—such as adding an extra serve of vegetables each day or cutting back on sugary drinks—can be a meaningful first step.
If you’re interested in integrating dietary support into your mental health care, we can assist you with our TMF program or refer you to other qualified professionals, such as GPs or dietitians, who specialise in nutritional mental health.
Frequently Asked Questions
No worries at all! The only thing to consider is whether you’ve previously qualified for Medicare funding. That said, we’re more than happy to consult with any patients and provide the care you need.

Maintenance TMS involves additional sessions after the initial course of TMS treatment, to sustain symptomatic relief and support mental health. These sessions may benefit those who:
- Notice a return of symptoms, post-treatment
- Seek to manage seasonal or stress-related depressive episodes
- Have a history of recurrent or chronic depression (or other symptoms, such as pain)
The aim is to stimulate targeted brain regions to prevent symptom escalation.
The frequency varies based on:
- Response to the initial treatment
- Mental health history
- Lifestyle and stress factors
Options may include a monthly session, a booster cycle every 3–6 months, or sessions during high-stress periods, as advised by a healthcare professional.
TMS delivers magnetic pulses to stimulate brain regions like the left dorsolateral prefrontal cortex, which is involved in mood regulation, aiming to support mental health outcomes.
Consider maintenance TMS if you notice:
- A decline in mood, energy, or motivation
- Increased anxiety, irritability, or sleep issues
- Difficulty concentrating or returning negative thought patterns
Consult a healthcare professional to discuss whether maintenance TMS is appropriate for you.
