-transporting nutrients around our systems
-eliminating waste products
-controlling our body temperature
-keeping our joints lubricated so they can act efficiently as shock absorbers
As a basic guide, most adults need about 1.5 to 2 litres of fluid a day.
The good news is that hydration helps fat metabolism through:
-Improved organ function – our kidneys and liver function much better with water. One of the liver's functions is to metabolise stored fat.
-Enhanced endocrine system – the growth hormone (hgH) is a fat burning hormone. Its efficiency is hugely reduced when the body is dehydrated.
-Better cognitive function – the brain is made up of around 80% water and is sensitive to changes in water level. A mere 2% reduction in hydration can lower cognitive function by up to 30%, which can lead to fatigue as well as a lack of motivation to exercise and eat healthily.
-Increased enzyme function – Lipase, the enzyme that metabolises fat has significantly reduced function when the body isn't properly hydrated. This can also lead to fatigue and inactivity.
So, how we keep hydrated?
-Keep a bottle of water with you when out and about.
-If you don't like the taste of plain water, try adding a slice of lemon to it.
-Drink water before, during and after a workout.
-When feeling hungry, drink water – thirst is often confused by hunger.
-If you can't remember to drink water, drink it according to a schedule at specific times of the day.
-Drink water when going out for a meal.
