Water Intake Calculator

Are you getting enough water? Dehydration can occur more often in hot weather, or with exercise. Some drinks are diuretic, meaning that although you are drinking, the electrolyte balance can be effected. The amount of water you need, varies with your weight. There are other factors that influence your need for water. As your Doctor or a Nutritionist or Dietician for more information.

How Much Water Should You Drink Per Day?

It makes sense that consuming water is imperative. The human body is about 60% water. Water is constantly lost through urine and sweat. Both functions which carry away toxins. If we lose more water than we consume, we become dehydrated. This is most often caused by failing to drink after, or during, exercise or through disease. If we lose as little as five to eight percent of our bodies fluids we can feel fatigued or dizzy.

How Much Water is Enough?

Many health authorities commonly recommend eight 8-ounce glasses, which equals about 2 liters, or half a gallon.
This is called the 8×8 rule and is very easy to remember. Other health practitioners believe we should always be sipping water throughout the day, even when we are not thirsty. Research seems to show that by the time we feel thirsty we are already dehydrated.

Your Brain needs Water

According to research, the brain is one of the first organs to be effected by even mild dehydration. The researchers observed women who were mildly dehydrated as a result of exercise and it showed it effected their brain function.

Research also shows that even as little as 1.35% decrease in body fluid levels can impact concentration and can be a factor in headaches. Factors such as working out, or hot weather or hot room temperatures can result in dehydration and can increase the bodies demand for additional water.

Why are Dieters encouraged to Drink Water?

Does water intake increase your metabolism and reduce your appetite? Apparently so, researchers found that drinking 500 ml of water resulted in increased energy expenditures by 30% and substrate oxidation rates. As a result it appears that drinking the suggested 8×8 (64 oz) of water can burn about 96 calories per day. Some of this calorie consumption comes from the bodies efforts in raising the temperature of cold water to body temperature.

It appears drinking water half an hour before eating can help adults consume less calories. Thirst mechanisms seem to get weaker in older adults, and older adults also seem to be the most effected by drinking half an hour before eating. Davy, Dennis, Dengo et al found that drinking water at breakfast resulted in older adults eating less calories at breakfast.

Studies have shown 30-44% improvements in weight loss among dieters who regularly consumed water, when compared to dieters who consumed less water.

Drinking Water as Prevention

In one study elderly women were given additional water to drink and the data was repeated with the use of doses of laxatives. It was found that drinking water is beneficial in preventing constipation. Water consumption has also been shown to be beneficial in lowering the risk of bladder and colorectal cancer. However, it can’t be concluded that water alone was the only factor in prevention of these cancers.

Drinking water can keep your skin younger and more resilient looking. It may also be a factor in reducing acne.

If you’re sweating a lot, make sure to replenish the lost fluid with water. Athletes doing very long, intense exercises may also need to replenish electrolytes along with water.

Water need is also increased during breastfeeding, as well as several disease states like vomiting and diarrhea.

Older people may need to consciously watch their water intake, because some studies show that the thirst mechanisms can start to malfunction in old age.
