Why drinking water, especially during weight loss, is so important

  1. Initial weight loss is largely due to loss of water, so you need to drink an adequate amount to avoid dehydration.
  2. The process of burning calories requires an adequate amount of water to function correctly; dehydration slows down the fat- burning process.
  3. Burning calories creates toxins (think of the exhaust coming out of your car); water plays a vital role in flushing them out.
  4. Dehydration causes a reduction of blood volume.  This causes a reduction in oxygen supply to your organs & muscles, which makes you feel tired.
  5. Water helps maintain muscle tone by assisting muscles in their ability to contract.  It also helps to lubricate your joints. Proper hydration can help reduce muscle & joint pain when exercising.
  6. A healthy diet, be it for weight loss or just good nutrition, includes a good amount of fibre.  But while fibre is normally helpful to your digestive system, without water it can cause constipation instead of helping to eliminate it.
  7. Drinking water with a meal may make you feel fuller sooner & therefore more satisfied eating less.
  8. As an infant we are 85-95% water.  By the time we reach 65 years old we are down to about 65% water.  As we are made mostly of water it is critical that we remain hydrated.


Water is excreted from the body in a number of ways:

  • Urine
  • Faeces
  • Sweat
  • Tears
  • Runny nose
  • Sickness &/ or diarrhea
  • Water vapour in the breath

It is absolutely necessary to replace lost fluids!!!
