Consequently, drinking plenty of water will naturally reduce the amount of food that you think you have to eat to overcome the feelings of hunger that you believe you are suffering.
You often see it quoted that you should drink eight glasses of water a day, but while this is a very reasonable starting point, the amount that you should drink as an individual depends upon your own metabolism.
Nevertheless, eight glasses of water a day would equate to somewhere around 3 to 4 liters, which is certainly a reasonable level of water to drink as a starting point, but if you want to drink more than this, then go for it unless you drink the equivalent of a tanker truck of water, no harm will come of it, and it will add no calories.
Also, you have to be aware that your body often confuses hunger and thirst, because in both cases, your metabolism is calling out for something to fill an empty space in your stomach.
Hence, when you are on a diet, try drinking water every time you believe that you are hungry. Give it 15 minutes to see if the feeling of hunger persists, because the majority of the time, it won’t, so water helps you to avoid taking in more calories than you need.
