25 June 2024

Feeling drained and struggling to focus at work? On Tuesday, 2nd July, our co-founder, Dr Nicholas Peat, GP with a specialism in Nutrition and Lifestyle Medicine, will be joining a panel of esteemed experts in an exciting online discussion at UCL Connect. This session will delve into the secrets of unlocking peak productivity at work.  

With this in mind, we thought we'd start the discussion and delve into the importance of nutrition for supporting workplace performance. After all, nutrition plays an integral role in an employee's ability to “show up” at work, both physically and mentally. So, ditch the afternoon slump and get ready to learn how simple, practical adjustments to your routine, including nutrition, can make a world of difference in your work performance! These are changes you can start implementing today. 

The Brain-Body Connection: Why Food Matters for Work Performance

The human body is an intricate machine, and just like any machine, it performs best when fueled properly. Food isn't just about providing calories; it's about supplying the building blocks and fuel for every cellular process, including those crucial for peak brain function. The gut-brain connection is a powerful pathway where what we eat directly impacts our cognitive abilities. 

Science is now revealing the fascinating interplay between nutrition and brain function. Foods rich in omega-3 fatty acids, like fatty fish and walnuts, are not just good for your heart; they're essential for the production of neurotransmitters that regulate mood, focus, and learning. On the flip side, diets high in saturated fats and processed carbohydrates have been linked to a decline in cognitive function and even an increased risk of dementia 

Differing behaviour of neurodiversity

Beyond specific nutrients, the body's ability to absorb and utilise these building blocks is equally essential. This is where the gut microbiome comes in. This complex ecosystem of bacteria plays a crucial role in digestion and nutrient absorption. Research suggests a healthy gut microbiome can improve cognitive function and mood, while an imbalanced gut can lead to brain fog and decreased focus.

The science behind the food-performance connection goes even deeper. Studies have shown that fluctuations in blood sugar levels can significantly impact cognitive function. Spikes and crashes in blood sugar, often caused by sugary snacks and refined carbohydrates, can lead to decreased alertness, difficulty concentrating, and even irritability. 

Understanding this intricate connection between food and brain function empowers us to make informed dietary choices that support optimal work performance. By prioritising a balanced diet rich in essential nutrients and promoting a healthy gut microbiome, we can fuel our brains for sustained focus, improved memory, and sharper thinking throughout the workday. 

Critical Nutrients for Peak Performance

As we’ve highlighted, your brain requires specific nutrients to function at its best. These essential building blocks play a crucial role in supporting energy levels, focus, and cognitive function, all of which are vital for peak performance at work. Let’s discuss a few key nutrients to consider when planning your nutritional intake to fuel your brain and body.  

Complex carbohydrates, found in whole grains, fruits, and vegetables, provide sustained energy for your brain. Unlike simple carbohydrates like sugar, which lead to a quick spike followed by a crash, complex carbs offer a slow and steady release of glucose, the brain's preferred fuel source. This ensures consistent alertness and focus throughout the morning, preventing the dreaded afternoon slump. 

B vitamins play a vital role in converting food into energy, impacting both your physical and mental stamina. Vitamin B12, for example, is essential for maintaining healthy nerve function and promoting focus. Similarly, B6 supports neurotransmitter production, influencing mood, memory, and cognitive function. Whole grains, legumes, and leafy greens are excellent sources of B vitamins. 

Minerals like iron and magnesium also play a significant role in work performance. Iron carries oxygen throughout the body, ensuring proper brain function and alertness. Magnesium supports healthy nerve function and promotes relaxation, which can be crucial for managing stress and maintaining focus during demanding tasks. Including lean meats, leafy greens, nuts, and seeds in your diet can help ensure you get enough of these essential minerals. 

But how do you incorporate these nutrients into your diet to help you stay energised and reach peak performance? The following section will explore practical strategies for building a brain-boosting meal plan and making simple dietary adjustments that can have a significant impact on your workday.

Nutritional Hacks and Habits for a Productive Workday

Here are some top tips to fuel your workday and keep you energised from the first email to the final deadline:

Breakfast for Champions

Ditch the sugary cereals and start your day with a balanced breakfast, prioritising complex carbohydrates and protein. Opt for whole-grain toast with eggs or Greek yoghurt with berries and nuts. These combinations provide sustained energy and keep you feeling fuller for longer, preventing those mid-morning hunger pangs.

Smart Snacking Strategies

Plan your snacks. Have healthy snacks readily available to avoid the temptation of vending machine treats and office biscuit tins. Fruits with a handful of almonds, carrot sticks with hummus, or a small yoghurt with berries are all excellent choices for beating afternoon slumps.

Fueling Focus During Meetings

Before long meetings or deadlines, opt for light and protein-rich meals. A salad with grilled chicken or fish or a lentil soup with whole-grain bread will provide sustained energy without leaving you feeling sluggish

Meal Prep Strategy

Conquer the week. Save time and ensure healthy choices by dedicating some time on the weekend to meal prepping. Pre-cook lean protein sources, chop vegetables, and portion out healthy snacks to have readily available throughout the week.

Stay Hydrated

Dehydration can significantly impact focus and energy levels. Invest in a reusable water bottle and set reminders to keep yourself hydrated throughout the day. For a flavour boost, add slices of cucumber or lemon to your water.

Mindful Munching

In today's fast-paced world, it's easy to eat on-the-go or while multitasking. Make a conscious effort to practice mindful eating. Savour each bite, chew thoroughly and avoid distractions while eating. This practice promotes better digestion, improves nutrient absorption, and can even help you feel fuller for longer.

By incorporating these simple yet effective strategies into your daily routine, you can transform your workday diet from a source of fatigue to a wellspring of sustained energy and peak performance.

Invest in Your Nutrition, Invest in Your Success

While the tips explored above offer immediate benefits for your workday, genuine and sustained work performance improvement comes from adopting long-term dietary changes that promote overall wellbeing. Here are three easy-to-incorporate adjustments that can make a world of difference: 

  1. Crowd Out the Bad: Focus on incorporating more whole, unprocessed foods into your diet. This naturally reduces the space for sugary drinks, processed snacks, and unhealthy fats. Fill your plate with colourful fruits and vegetables, whole grains, and lean protein sources.

  2. Cook More at Home: Taking control of your meals lets you prioritise healthy ingredients and portion sizes. Experiment with new recipes that incorporate brain-boosting nutrients, gradually reducing reliance on processed convenience foods.

  3. Mindful Moderation: While certain foods should be limited, complete deprivation is often counterproductive. Allow yourself occasional treats in moderation, and focus on creating healthy habits that you can maintain for the long haul. 

        Making these long-term changes may seem daunting at first, but remember, even small adjustments can have a significant impact. Start by introducing one or two changes at a time and gradually build upon your successes.


        In conclusion, a performance-driven diet isn't just about quick fixes; it's about investing in your long-term wellbeing and professional success. By prioritising proper nutrition, you're fueling your body and mind with the tools they need to perform at their peak. Remember, Invest in Your Nutrition, Invest in Your Success! You'll be amazed at the difference a healthy diet can make in your energy levels, focus, and overall productivity. So, ditch the afternoon slump and embrace the power of a performance-driven diet! 

        Investing in your wellbeing is not just an expense; it's a strategic investment.
