Emotional Eating and Brain Chemistry: How Relying on Food for Pleasure can Keep You Stuck
Emotional eating can feel like an endless loop of cravings, overeating, and guilt, leaving many searching for ‘solutions’ that often miss the mark. Contrary to popular belief, the key to breaking free from troubling patterns isn’t about restricting food or summoning more willpower. Instead, it’s about exploring the deeper drivers behind these behaviours.
One piece of the puzzle lies in brain chemistry - specifically, the role of neurotransmitters like dopamine and serotonin. These chemical messengers play a powerful role in shaping our mood, behaviours, and food choices. Understanding their influence can help us make more sense of why we turn to food for comfort, and take strategic steps to help regain balance in a sustainable way.
As you read on, I also encourage you to keep in mind that emotional eating exists on a spectrum and can be part of a regular, normal relationship with food - only you can determine the extent to which it is impacting your wellbeing.
The Role of Dopamine in Emotional Eating
Dopamine is often called the ‘reward’ neurotransmitter because it is responsible for feelings of pleasure and motivation. When we participate in something we enjoy or achieve a personal goal, dopamine is released in the brain, reinforcing the behaviour and encouraging us to repeat it. Dopamine not only reinforces pleasurable activities but also influences learning and habit formation.
Eating is one of a number of things that can raise dopamine naturally. This in itself is not a problem - eating should be pleasurable and satisfying! However, if we find ourselves struggling with a low mood, apathetic, and consistently turning to food to pep ourselves up, this may indicate an imbalance.
Low dopamine could show up as persistent cravings for sugary, fatty, or salty foods to compensate for the deficit and help temporarily relieve discomfort related to difficult emotions. Overtime, cravings may intensify as the brain seeks a quick dopamine ‘fix’, and you might feel unsatisfied even after eating large quantities.
You could also feel unmotivated to prepare or choose healthier options, opting instead for convenience foods, or experience a general lack of motivation on other aspects of your life..
It’s not just about dopamine levels but also about receptor sensitivity to dopamine, which can vary due to genetics, stress, or repeated exposure to certain foods over stimulating the reward system.
The Role of Serotonin in Emotional Eating
Serotonin, another key neurotransmitter, is crucial for mood regulation and appetite control. While dopamine focuses on reward, serotonin contributes to feelings of contentment and satiety.
When serotonin levels are low, emotional eating behaviours can arise as the brain seeks to compensate. Low serotonin is linked to mood disorders like anxiety and depression, which are often triggers for emotional eating. Carbohydrate cravings are particularly common, as these foods temporarily boost serotonin levels.
Serotonin also helps signal fullness, preventing overeating. A lack of serotonin can disrupt these signals, making it harder to recognise when you are satisfied.
Serotonin’s role extends beyond its contribution to mood and appetite regulation - it also affects sleep, digestion, and overall emotional wellbeing.
Why Restrictive Eating Isn’t the Answer
Restricting certain trigger foods or even entire food groups may seem like a solution to emotional eating, and for some people, perhaps it may help for a while. However, for many it can be the trigger that initiates the problem, or worsens the problem by:
• Disrupting serotonin production – carbohydrates are essential for serotonin synthesis. Eliminating or severely limiting them can reduce serotonin levels, increasing mood instability and cravings.
• Increasing the allure of restricted foods – when certain foods are restricted, they can become psychologically “forbidden,” ironically heightening their desirability. So the brain’s reward system may become more sensitive to these foods, making them seem disproportionately rewarding when eventually consumed.
• Triggering the binge-restrict cycle – the deprivation caused by restriction often leads to overcompensation, where the brain drives overeating to restore perceived balance. Over time, repeated cycles of food restriction and overexposure can reduce dopamine receptor sensitivity, where larger quantities of these foods are needed to experience the same reward.
• Elevating stress hormones – restriction can increase cortisol levels, which may further impair neurotransmitter function and emotional regulation, exacerbating the struggle with emotional eating.
How to Restore Balance
Serotonin and dopamine systems are interconnected, and chronic stress, inadequate nutrition, and sleep deprivation can all impair both systems. So, if your emotional eating feels out of control, you may wish to consider how you could better support your neurotransmitters and help restore a sense of balance. Here are ideas to get you started:
1. Prioritise sleep
Rest and sleep are essential for balancing both dopamine and serotonin. During sleep, dopamine receptors reset, ensuring optimal sensitivity and motivation levels, while serotonin is replenished, supporting mood stability and emotional regulation. Prioritising quality sleep helps prevent neurotransmitter imbalances, reducing cravings and the likelihood of emotional eating triggered by stress or fatigue.
2. Break the cycle of food cravings (dopamine focus)
Find and maximise your opportunities to experience alternative ‘rewards’ - this means finding ways to regularly engage in non-food-related activities that bring joy and naturally boost baseline dopamine levels. This one is key. Some examples are hobbies or social interactions. Engaging in joyful movement is known to be one of the fastest ways to raise dopamine levels. Consider how you may be able to incorporate this in your day. If you can manage some movement in a morning - even a brisk walk to work - this might just help with a little boost to help set up your day.
Get outside - Sunlight exposure plays a vital role in dopamine regulation by stimulating dopamine production and improving receptor sensitivity, particularly through morning light.
Eat mindfully - slow down and savour your meals to shift focus from reward-seeking to satisfaction.
Include nutritionally supportive foods - do not restrict your diet and include tyrosine-rich foods like fish, dairy, nuts and legumes in your daily diet to help support dopamine production.
3. Support emotional wellbeing (serotonin focus)
Stress management - incorporate specific relaxation techniques like yoga or deep breathing to reduce stress and improve mood stability.
Lifestyle practices - regular exercise, mindfulness, and exposure to sunlight can naturally boost serotonin levels.
Include nutritionally supportive foods - do not restrict your diet and include foods rich in tryptophan (e.g., eggs, turkey, nuts, seeds) and complex carbohydrates to support serotonin production.
Seek out coaching support or therapy options - consider Intuitive Eating Coaching to help you redefine your overall relationship with food and self-care habits, or therapies such as ACT (Acceptance and Commitment Therapy) to help address underlying emotional patterns and behaviours and gain the tools you need to better meet your emotional needs.
My Conclusions
If you are struggling with emotional eating, please reassure yourself that this is a common challenge, and essentially all that you’re striving for is to feel better.
Given food’s capacity to influence our biochemistry, it can often provide the ‘feel good fix’ we are craving in the moment. However, an over-reliance on food to soothe uncomfortable emotions can be an unhelpful path to take in the long-term.
Dropping the struggle is not a matter of willpower or food restriction. And, if emotional eating is something you feel you need to address, there are a number of underlying considerations, not all addressed in this blog.
However, by considering whether neurotransmitter imbalances are playing a role in your eating habits, you may be able to take some actionable steps to better support your biochemistry, raising your mood and motivation naturally.
Focussing on approaches and strategies such as getting more rest, engaging in joyful movement, stress management, emotional regulation, social connection, and taking a balanced approach to nourishment are some of the key ways you can explore to do this.
