5 Brain-Boosting Snacks To Help You Beat The Afternoon Slump!


You’re at work, it’s 3pm, your brain is foggy and your stomach starts rumbling… but dinner is still hours away. We’ve all been there! You start looking for a pick-me-up, reaching for coffee and craving sweet treats. Whilst this seems to work initially, after a while your brain and willpower just totally give up. You become even more sluggish and the sugar cravings seem to intensify. Why is this happening? To put it simply, the more sugar you eat, the more you crave – welcome aboard the blood glucose rollercoaster. When blood glucose levels are too high, it triggers a huge insulin release which causes your blood sugar to drop… explaining the highs and lows in energy levels.

High-sugar foods don’t just affect the release of insulin and your energy levels, they also affect your gut and the state of inflammation in your whole body, which has an immense impact on your brain function. This is because some of the key brain chemicals are produced in the gut, such as serotonin (90% produced in the gut), dopamine and GABA. Serotonin is a natural antidepressant that also plays a key role in regulating your mood, appetite, sleep, memory and learning. Dopamine is the neurotransmitter of desire and motivation, and GABA is your calming brain chemical that improves focus and reduces anxiety, stress and inflammation.  So, if your gut is out of balance, you may end up feeling anxious, moody, forgetful, unmotivated, unable to focus and just feeling generally ‘blah’.


Some things that negatively impact gut health include:

  • Eating processed foods

  • Eating too much sugar or artificial sweeteners

  • Accidental chemical consumption, such as lingering pesticides on unwashed fruit

  • Drinking two or more alcoholic beverages per day

  • Medication, such as antibiotics and pain killers

  • Poor dental hygiene, which allows bacteria to grow in your mouth

  • High levels of stress or anxiety, which can weaken your immune system


Your state of hydration is another key factor affecting brain performance. Only a slight state of dehydration can lead to a decline in your visuomotor, psychomotor, cognitive performance, memory and contributes to increased tension/anxiety and fatigue.

 So how can you stay physically and mentally alert and energised throughout the day? There are few simple nutrition hacks that you can implement in order to stay focused and cravings-fee. Start by staying away from anything that could upset your gut (such as the tips mentioned above). Then, there are some natural brain-function enhancing supplements you can add to your diet to get the extra kick without compromising your health (and waist line)!


Here’s our top 5 brain boosting afternoon snacks:


1.    Matcha Blueberry Muffin

A blueberry muffin with your afternoon coffee… sounds so tempting. However, a regular blueberry muffin has around 350 kcal, 55g of carbs and around 30g sugar (that’s 7 ½ teaspoons)! This kind of treat is not just going to hinder any fat loss efforts; it’s also going to send you on a sugar high… followed by a huge energy slump and more cravings. But, as always, there’s a way around it. This matcha blueberry muffin contains only 161 kcal, 7g carbs and 4g sugar. It has also the added brain boosting benefit of green tea. It’s a win-win situationJ


Ingredients (makes 4-6):


·      1 cup almond meal

·      2 eggs

·      Stevia (sweeten to your liking)

·      1 teaspoon cinnamon

·      2 tablespoons matcha powder

·      ¼ teaspoon baking soda

·      ½ teaspoon apple cider vinegar

·      1 cup berries (optional)




·      Combine the almond meal, baking soda, stevia, matcha and cinnamon in a bowl

·      In a separate bowl, combine the eggs and vinegar

·      Stir the dry ingredients into the wet ingredients (add the berries if you wish), mixing until combined

This ancient superfood is packed with important brainpower nutrients such as omega-3 essential fatty acids, antioxidants, protein, calcium, iron, potassium, vitamins A, B, E, and D, as well as other minerals. Two tablespoons of chia seeds contain 10 grams of fibre, 6 grams of protein, more calcium than milk, more omega-3s than salmon, more iron than spinach and more antioxidants than blueberries! This makes them one of the best brain-nourishing foods, with the added benefit of also keeping you hydrated.




·      4-5 tbsp chia seeds

·      ½ cup almond milk

·      ½ cup fresh berries

·      ½ sliced banana

·      50g yoghurt

4.    Mini Egg Frittatas

Egg is also hugely beneficial for optimal brain function due to the high levels of vitamins B6 and B12, folate and choline. Choline is a key nutrient in the synthesis of acetylcholine, one of the neurotransmitters regulating your mood and memory. Make sure you eat the yolks as there’s no choline in the white. The white is high in protein so we recommend eating the whole egg! B-vitamins and folate are essential for an optimal brain health including synthesizing brain chemicals, regulating sugar levels in the brain and preventing depression. One egg a day will keep your bad mood swings away!




·      5 eggs (to have one per day)

·      Bacon or ham (you can replace this with salmon or zucchini slices)

·      Salt and pepper

·      Fresh herbs (basil or dill go well with this dish)

·      Coconut oil/olive oil spray



·      Cut bacon/ham in 5cm thick slices

·      Spray a muffin tin with a coconut oil

·      Lay the slices around each muffin cup

·      Fill each with one egg and top with salt, pepper and herbs

·      Bake for 20-25min on 170-200 Celsius (depending on your oven; just keep checking)



·      You can also add chopped up veggies of choice. Bacon first around the cup, veggies on the bottom, then top up with egg. You can also make these without bacon or ham, just with veggies and eggs.

·      Use zucchini slices instead of turkey
Ditch the turkey and add some shredded grilled/steamed salmon with the veggies


5.    Brain Power smoothie


As mentioned earlier there are some healthy natural supplements that will give you an extra kick to help you stay alert and focused. Lion’s Main mushroom powder or Cordyceps powder by Four Sigmatic are our two best picks. Lion’s Main can improve your memory and may assist with higher and longer concentration levels. Cordyceps is not a stimulant as such but it will help you to maintain constant energy levels as it activates the body's own energy production in the cells.


Cinnamon is great for lowering your blood sugar levels and it’s also beneficial for your gut health. Berries are full of antioxidants which prevent inflammation and chia seeds are great for your brain.


If you can tolerate coffee, you can also add it in for an extra caffeine fix!




  • ½ a small, frozen banana

  • 1 cup frozen berries of choice

  • 1 tablespoon chia seeds

  • 1/2 teaspoon ground cinnamon

  • 3/4 cup almond milk

  • 1 scoop Nuzest Clean Lean protein powder (or any low sugar protein powder, free of artificial additives and fillers)

  • Lion’s Main mushroom powder or Codryceps powder

  • Optional: 1 shot espresso or 1 tsp matcha powder
