Water: Are you drinking enough?

Water: are you drinking enough?

Whether your goal is to lose body-fat, improve your strength, enhance your performance, or to help off set some of the signs of the ageing process, drinking sufficient water on a daily basis should be an essential part of your routine.

You can dial in your nutrition and training, but without sufficient water, your gains and progress WILL be limited.

Water constitutes two thirds of your total body weight and is the single most important nutrient we require, without it you wouldn’t survive more than a few days!

In a survival situation, water is more important than nutrition,as all of your cells and organs require water to function efficiently and effectively on a daily basis. We obviously obtain water by drinking it directly, but also from our food.

The human body will lose water through perspiration, respiration and urination so keeping a regular intake is essential for optimal performance, especially when exercising regularly. Studies have shown that dehydration reflected in a 1-2% reduction in body weight can reduce our ability to concentrate, our cognitive and physical performance, and increase feelings of aggression or irritation – water rage!

As a general rule an active person who is training consistently should aim to consume 1 litre of water per 25 kg of total body weight.

Therefore a 65 kg person should drink: 2.6 litres per day (65 divided by 25).

Remember that this amount should be drank throughout the day in regular intervals; the average standard water bottle is 500ml, so using the above example this would equate to be just over 5 bottles per day.

Also remember that fizzy drinks/sports drinks/and tea/coffee shouldn’t be included in the above total!

Action tips:

  • Take a water bottle or shaker with you to work and fill it up at regular stages throughout your day. If you spend prolonged time travelling with work/business, always have your water on hand in your car.
  • For every cup of coffee you order/drink get into the habit of ordering/drinking a glass of water to supplement the coffee. From personal experience, very often the water is forgotten about and you may have to make a polite reminder! 
  • Don’t go crazy and start to increase your intake massively within the first few hours of your day! Gradually build up to your requirement (using the formula above), especially if you are already considerably below your target requirement. Start small….
  • Yes you will initially start to urinate more frequently (politely speaking) as your body adapt to the increase in liquid, you will get used to it!

That’s all for today, until the next time,
