Pretty much every 'diet' you read about stipulates that you must drink 6-8 glasses of water a day. It seems like a lot.
I don't mind drinking water. I can easily tuck into a litre or so a day, most of the time. 1.5L - 2L is a little out of my league though.
In the spirit of unlocking the science, I did a bit of a 'google' search on water and weight loss. Here are some of the facts that I discovered:
- Your brain can't detect the difference between hunger and thirst. If you are 'peckish', have some water first and then see how you feel.
- Dehydration causes water retention which causes bloating and can make you weigh a kilo or two more.
- Water maximises weight loss because it allows your kidneys to function properly which means that your liver doesn't have to take over the role of processing fluids which means the liver can do what it is supposed to do, convert fat to energy (metabolise fat).
- Water helps activate fibre in your body which means that toxins and fats are 'flushed' rather than stored
- Water helps 'flush' toxins and fat in its own right
- While your body can manage upwards of 20 Ls of fluids per day, your best bet is to drink slowly and frequently rather than ingest large quantities in fewer intervals. Stop about 3 hours before bed. You know why.
- In the first few days when you increase your water intake and you are running to the toilet constantly, remember that this is a good thing. Your body is being released from 'survival mode' and excreting the fluid you have retained (in your ankles, hips and thighs), trusting that the water will keep coming. You will eventually reach 'breakthrough point' where all the flushing settles.
- Drinking water can decrease your appetite.
- 8 glasses is excessive for healthy and certainly not overtly ill people. Large intakes of fluid, equal to and greater than 8 × 8oz, are advisable however for the treatment or prevention of some diseases and certainly are called for under special circumstances, such as vigorous work and exercise, especially in hot climates. Some studies indicate that caffeinated drinks, alcohol and 'sports drinks' may be counted in the fluid count for the day.
- Water has a positive impact on your skin.
