Water (like oxygen) is one of the vital components for our survival. Without water one can't imagine the life on earth.
Why is it important to drink water, especially for losing weight?
Of the several reasons, the main ones are listed below:
1. Initial weight loss is mainly due to loss of water.
2. Weight loss is the process of burning more calories than taking in (see more on Weight Loss). For this, an adequate supply of water is a must in order to function efficiently; dehydration(lack of water in your body) can slow down this fat-burning process.
3. Burning calories(energy) releases harmful toxins, similar like the exhaust coming out of your car, and water plays an important role in flushing them out of your body.
4. Weight loss diet includes a good amount of fiber. But while fiber is normally helpful to our digestive system, at the same time it can cause constipation and gas problems without adequate fluids (see more on Fiber Weight Loss). So water is necessary for us.
5. Dehydration lowers blood volume in our body due to which there will be less supply of oxygen to our muscles and a reduction in the supply of oxygen to our muscles can make us feel lousy and tired which can result in weight gain.
6. Muscles have the ability to contract. Water can assist this ability and can help in mantaining the proper muscle tone. Water can also reduce muscle and joint soreness when you are exercising.
7. Drinking water with a meal can make you feel full sooner and therefore can prevent us from overeating. But drinking water alone may not have this effect. At first our body should feel satiated (not hungry). That means we should be full of calories and nutrients.
Now question arises "How Much Water Should I Drink?"
You must have heard that you should drink at least eight 8 glasses of water a day. But there is no any hard and fast rule governing how much water an individual must drink in order to be fit. The specific amount of water that you should drink actually depends on several factors like your age, gender, weight, level of activity, and even the temperature and humidity of your environment, and your diet as well. Your diet could also make difference (see more on Weight Loss Diet). As for say, if you eat plenty of fluid-rich or say water dense foods like fruits and vegetables your need for drinking water will get lowered.
For me a good way to keep myself hydrated throughout the day is by drinking one glass of water with each meal and one between each meal.
