Why Water is the Key to More Energy!

Feeling Fatigued? Why You Should Reach For Water Before Coffee!

If you’re struggling with energy levels throughout your day, you might find some handy hints in this article. Most people only think about food when it comes to nutrition – but did you know that water is actually more essential than any of the nutrients we find in food?

And… I just found out how to calculate how much water YOU need… so read on to find out!

Why is water so important?

Without water, your body wouldn’t be able to function. Water plays a role in nearly every process within your body, either directly or indirectly. You’re made up of about 60% water – men and infants have a little more, whereas women and people with a high body fat percentage have a little less. You will find water in your intracellular and extracellular fluids, plasma, organs, spine and digestive tract.

Water is needed for actions including:

  • Maintaining body temperature
  • Forming a barrier in the skin to protect against foreign bodies
  • Brain function
  • Digestion of food
  • Excreting waste through urine, sweat and faeces
  • Supporting a healthy metabolic rate (key for weight loss and energy!)
  • Increasing satiety levels

Without enough water in the body, we become dehydrated. Even a little bit can make a big difference. Research has shown that 1-3% dehydration can impact on processes such as brain function, memory, energy and mood – so if you’re struggling with fatigue it could be that you’re dehydrated!

 So How much water should you drink?

Different people have different needs for water, depending on their body composition, exercise level, medication use and other lifestyle factors. Even the weather can influence how much you should be drinking.

Government recommendations are around 2.1-2.6L of fluid per day. But if you’re not drinking water much, it’s best to start slowly and work your way up.

If you’re exercising, you’ll want to add 1-2 cups of water for every 30 min of exercise you do. If the temperature is over 30 degrees C, add an extra 2 cups per day.

When I did my training to become a Metabolic Balance Coach, I was trained in this simple equation to work out exactly how much water YOU need:

Your daily water requirement = 35ml per kilo of body weight.

So if you weigh 80kg, then you need at least 2.8L of water every day. More if you’re exercising, as mentioned above.

Weight Loss Tip: Interestingly, not getting enough water can block fat burning. So if you’re like many of my clients and need to release weight, then make sure you drink your required amount of H2O! As your weight decreases, you can drink less.

 How to boost your water intake

Now that you know how important hydration is for more energy, how can you get enough? Here are some simple tips to get more water into your day.

Make drinking more fun

Many people find plain water a bit boring. But if that’s the case, you can make it more interesting and still reap the benefits. As the weather warms up, you can add fresh or frozen fruit and herbs to your water. Berries, citrus, mint and rosemary are some refreshing options to start. When the temperature drops, find some herbal teas you enjoy to replace plain water.

If you’re out at a social event and want an alternative for soft drinks, grab some sparkling water. Many supermarkets now have flavoured options – just make sure there’s no added sugars.

Eat your water

You don’t have to rely on your water bottle for all of your hydration needs. There are plenty of high-water foods around, especially as the warmer months bring tropical produce back!

Stock up on:

  • Melons
  • Berries
  • Peaches
  • Cucumber
  • Celery
  • Apples
  • Pears
  • Green leafy veggies
  • Broccoli

Create a habit

The easiest way to incorporate a new habit is to tie it to a current one. This goes for drinking water as well. You could try drinking a glass of water after brushing your teeth or when you go to make a cup of coffee. If you check your emails regularly, have a few mouthfuls every time your inbox loads up, or before you compose a new email.

Figure out what you do at least 4-5 times each day and make those the times that you drink a glass of water.

Remind yourself

Sometimes, we need someone to push us until we get into a habit. In that case, it’s time to set up some reminders. You can simply set alarms on your phone throughout the day. There are plenty of apps out there that track water, from general diet trackers to specific water trackers.

If you aren’t into tech, you can get water bottles with measures on the side to remind you visually. I love this one here from Healthish: https://healthish.com/products/wb-1


Drinking enough water is just one piece of the puzzle. If you’re feeling tired all the time, have foggy thinking, struggle to lose weight or have ‘hormones gone haywire’, book in a session with me!
