Feel exhausted even though you had a good night’s sleep? Struggle to find energy to focus fully on your job, play with the kids or achieve everything you want in a day?

And, because you are tired all the time, do you find that you are often cranky, unmotivated and unnecessarily impatient?

Trust me, you’re not alone.

These days, chronic tiredness and poor moods have become so common, that we’ve actually started accepting them as normal. We live such busy lives and so many people around us feel tired all the time, that it must be normal if we do too, right?

The reality is, it’s not.

Sure, if you regularly sleep less than 7-8 hours or are waking up a lot during the night, you’re unlikely to wake up rested. Or, if you have certain medical conditions such as diabetes, an under-active thyroid or an autoimmune disease, these can contribute to your constant tiredness too.

But the truth is, there is one other factor that massively affects your energy levels and that, for many of us, is a number one cause of chronic tiredness - and that is your diet.

The food you eat (or don’t eat) every day, drinks you consume (or don’t) and the eating habits you cultivate.

Yes, the food can make you tired and cranky - or it can help you feel energetic and full of life as you like it!

So why exactly is food so powerful?

(1)  Wrong Foods Can Wreak Havoc on Your Gut

Gut health has received a huge amount of attention over the last few years, as studies have shown that it affects everything from our digestion, immune system, sleep, and even our food cravings.

And, we now know that what’s happening in our intestines also has an enormous impact on our energy levels and moods.

Why is that the case?

In your gut there are billions and billions of different bacteria, some of which support your health while others do not. One of the things that the “good bacteria” do is help absorb nutrients from the food that you eat, including B vitamins, magnesium as well as iron, which are all very important for good energy levels.


The “bad bacteria” - you guessed it -have the opposite effect and when they overgrow and the balance between the “good” and the “bad bacteria” has been ruined, the absorption of these nutrients is compromised too. And if the nutrients that are key for healthy energy levels are not adequately absorbed, well, then greater tiredness and fatigue are likely to follow.

What’s important to know is that one of the main factors that affect this balance between the “good” and “bad” bacteria, is the food that you eat.

For example, a diet high in processed foods can very quickly lead to an overgrowth of the "bad bacteria", as these typically feed on simple carbohydrates and unhealthy fats that processed foods are full of. Pizza, pasta, bread, muffins, cakes - you name it, the "bad bacteria" love them all!

The "good bacteria", on the other hand, feed on certain types of fibre that is found in foods like flax-seed and oats, so a balanced diet with enough whole foods and little processed products will not only help these bugs stay alive and grow, but will also support your energy levels in the process.

So, how do you know if your gut is out of balance? Here’s a quick quiz that will help you find out:

(2)  Poor Eating Habits Can Send Your Blood Sugar On A Roller-Coaster Ride

One thing is clear - there is no stable energy without a stable blood sugar.

Blood sugar refers to the level of glucose in your blood and our bodies all have a blood sugar range that is considered normal and that they work hard to maintain.

When you eat, glucose from your food gets released into your blood stream which causes a rise in your blood sugar. From there, insulin pushes this glucose into the body cells where it can be converted into energy and, in this process, also lowers your blood sugar level. If your cells already have enough energy, excess glucose gets stored in your body as fat.

When you eat regularly and your meals are balanced, this rise and fall of the blood sugar happens within the normal range. This is also when your energy remains good most of the time, when your mood feels settled and when you don’t tend to experience extreme hunger or sugar cravings.

But, when your diet is imbalanced and your meals are, for example, too high in processed foods or sugar, or when you have an irregular meal schedule, your body struggles to maintain blood sugar within the normal range. This can then lead to very short surges of energy, followed by a longer period of extreme tiredness, irritability and sugar cravings.


So, if you are often finding yourself on a mid-afternoon journey to your office canteen or your home cupboard for that pick-me-up chocolate bar, this is what your cravings are all about!

Of course, if you maintain this type of diet for a long time, your blood sugar can’t get off this roller-coaster, and soon fatigue and poor moods are no longer just a one-off inconvenience, but a regular occurrence in your life.

(3)  Imbalanced Diet Can Lead To Nutrient Deficiencies

The food you eat every day provides you with several nutrients that have an enormous effect on your energy and moods, including B vitamins, magnesium, Omega 3, vitamin D, zinc, iron and potassium.


B vitamins, magnesium and zinc, for example, work together in your body to turn the food you consume into energy. If you don’t get enough of these nutrients from food or supplements, then your body simply cannot produce as much energy as you need, leaving you more tired than you would normally be.

On the other hand, Vitamin D or the "sunshine vitamin" is very important for good moods, as it encourages the production and release of serotonin in your brain, which is one of the so-called “happy hormones”. So, not enough vitamin D means less serotonin, and with that poorer moods.

And then there’s iron, which helps transport oxygen from your lungs to other organs and tissues, thereby affecting how well they function. If you don’t have enough iron in your system, your organs will have less oxygen and they will have to work harder to do their job, making you more tired.

Potassium also plays a role in your energy levels and Omega 3 affects your mood, both via their own unique mechanism.

Of course, a poor diet can very quickly result in a lack of one or more of these nutrients and the more of these your body is lacking, the worse your symptoms of low energy and poor moods will be.

Stress, coffee, alcohol, lack of sleep and smoking further speed up the rate at which your body uses some of these nutrients, so if any of these factors are a regular part of your life, it’s even more important that you fill these nutrient gaps to get your energy back and feel good.

If you suspect that you might be low in some of these nutrients too, you can download our free nutrient check list below, and get an initial sense of where your challenges might be.

So, these are the three most common ways through which food may be contributing to your tiredness and poor moods.

The good news is that all of this is fixable and these challenges can be tackled through simple changes in your eating habits. And, these changes don't even need to be radical - often just a few tweaks to your daily nutrition can make a massive difference in how you feel and help you get your spark back!
