Bid farewell to cognitive fog: discover how to manipulate your mitochondria, the body’s sources of energy

Raise your hand if you constantly struggle with fatigue or believe that your daily energy has vanished. Though gloomy days and dark mornings can certainly have an impact, if you find yourself losing energy all the time, there may be a deeper issue at hand. Something might be wrong with your biology.

Trillions of cells make up the basic building blocks of your tissues and organ systems, which are found throughout your body. These cells include a variety of parts, each of which plays a very specific job. The mitochondria are one of these cell components. These are tiny structures that resemble batteries and generate chemical energy known as ATP to power daily activities. It sounds complicated, and that’s for sure.



“Mitochondria are the body’s energy generators. Found in almost every cell, these tiny ‘power stations’ convert the food we eat into fuel to power the biochemical processes that keep us alive and functioning. Whether it’s maintaining muscles or keeping our heart beating efficiently, or activating immune cells we depend on mitochondria to meet our body’s energy needs,” explains Caroline Hind, a registered nutritionist at Nutrable, a personalized corporate nutrition service.

Not to be confused with mitochondrial disease, (an umbrella term given to rare genetic disorders), if you’re more sluggish than usual it could be because these structural cell power plants might not be able to use your food to generate optimal energy flow. Or you might have a slight shortage in mitochondria which leads to low levels of energy production. As Hind explains, “A complex web of causes might include hormonal imbalances, nutrient deficiencies, stress, and exposure to toxins.”

Struggling mitochondria is a scenario that Hind has seen time and time again in her busy corporate clients. “The brain and its complex messaging system of nerves, hormones, and neurotransmitters rely on energy produced by mitochondria too,” she explains. “So, in the workplace, people often struggle with brain fog, difficulty concentrating, poor mood, and poor memory when mitochondria are not working so well.”

Whether you spend most of your time desk-bound or on the go, some simple hacks can help to revive sub-functioning mitochondria and bring back your spark.

Swap five-a-day for seven-a-day

Harmful free radical molecules are generated by exposure to things like cigarette smoke, air pollution, and even sunlight, and these are key factors that contribute to mitochondrial dysfunction.

Free radical’s worst enemy? Antioxidants. Found in brightly colored fruit and vegetables antioxidants counteract the damaging effect of free radicals – but your five-a-day won’t cut it. Reach for a minimum of seven portions of rainbow bright fruit and veg, (choosing low-sugar options like berries, apples, and spinach) to keep your mitochondria happy. Sneak greens to breakfast smoothies, blend roasted root veg into homemade soup, and grate brassicas like broccoli and cauliflower into pasta sauces.


Follow a fasting window

Strict intermittent fasting might not cut the mustard for everyone, but a doable fasting window might just be the ticket to repairing damaged mitochondria according to science.

A realistic time-controlled eating cycle for the average person is to eat within an eight-hour window, for example between 10 am and 6 pm. “Giving the body longer periods without eating is a great step towards caring for your mitochondria,” says Hind.

And it’s not just about when you eat, but what you eat that will help to fast-track your mitochondrial function. A highly refined carb diet generates free radicals so white bread, and pre-packaged biscuits will only add to mitochondrial exhaustion, whilst small amounts of healthy complex carbohydrates like brown rice and wholemeal bread get the green light.

“Reduce sugary and starchy foods. Instead choose protein-rich foods and unprocessed fats such as those found in fatty fish, olive oil, eggs, coconut oil, and avocado to ensure your mitochondria have a chance to burn a ‘cleaner fuel,'” continues Hind.

Pop a vitamin pill

Fuelling your body with a variety of nutrients can help to give your battery life a kickstart. A whole food diet is a way forward, but if you’ve been burning the candle at both ends, supplementing with a high-strength multivitamin will help to top up some of those all-important mitochondria-loving secret nutrients.

“Mitochondria can only work efficiently if they are supported by the vital nutrients that act as catalysts and regulators of the chemical processes within our cells. Magnesium, vitamin D, and B vitamins can ensure a good supply of the nutrients needed to maintain cellular function,” says Hind.

Add coconut oil to your coffee

Coconut oil is a wonder food that will rev up your mitochondrial energy reserves thanks to its unique healthy fats called medium chain triglycerides (MCTs).

“Research shows these fats support good mitochondrial production and function. Use coconut oil for cooking or choose a teaspoon a day of an MCT supplement,” says Hind.

You could even join the TikTok coconut oil fan club and add a teaspoon to your morning coffee, but remember to wait one hour after rising before having your cup of Joe. This way you’ll align with your body’s natural cortisol levels which naturally start decreasing 60 minutes after you wake up. The result? An extra dose of alertness.


Get your sweat on

Unsurprisingly keeping active will ensure your mitochondria are fully charged, and whilst any movement is beneficial, it’s thought that the more vigorous the workout the greater the mitochondrial pep up.

Morning exercise when your natural cortisol levels are highest will probably produce the best effects. “If you show your body you need a good energy supply, it will up-regulate your energy-production machinery,” says Hind. So whilst it might be tempting to sidestep that Barry’s Bootcamp HIIT session for a stroll in the park, a high-intensity interval training workout could help to fire up mitochondria.


Forgo weekend lie-ins

Mitochondria love running on a regular circadian rhythm (your body’s internal 24-hour sleep-wake cycle), so if you find yourself in a constant sleep debt, these cell power machines probably aren’t getting the recharge they need. “Going to bed later than 11 pm every night will add stress to your body and disrupt your circadian rhythm, ultimately leading to impaired sleep quality,” says Hind.

Beat the sleep energy thief by going to bed and waking up at the same time every day — this means forgoing weekend lie-ins and concentrating on rejigging your daily rhythm instead.
