Unfortunately, with this particular piece of advice they are right. It’s not a coincidence that roughly two thirds of our body is made up of water and two thirds of our planet is covered with the stuff. All living things need it. For our cells to function at their best, they need a good supply. Every function of our body is dependent on healthy cells so if we don’t look after them everything suffers. Particularly those who want to lose weight should consider their water consumption. One of the liver’s many functions is to metabolise fat. However, it also has to help out the kidneys on occasions. The kidneys rely on water to function properly, so if they are not receiving enough water, the liver has to help out with the workload. This means the liver can’t metabolise fat as effectively – so it makes sense to drink more water.
The suggested 8 cups of water a day is a rough guide. However, the bodies demand for different nutrients is dependent on several factors. One of those factors is body weight. To calculate a more accurate estimation of how much water your body requires you can use the following equation. Body weight in pounds divided by 2 = number of ounces of fluid per day 1 fluid ounce = 0.03 litres Example: A man weighing 200 lbs should aim to drink minimum of 3 litres of water a day. 200 / 2 = 100 100 x 0.03 = 3 However, a good starting point is to develop the habit of drinking a large glass of water with every meal, including snacks. This will also make you feel fuller and help prevent an over consumption of calories.
