Water for Weight Loss
Water is THE most important element of your fitness routine. Simply put, the kidneys cannot function properly without enough water. If your kidneys are not functioning to capacity, then your liver steps in to assist. The primary function of your liver is to metabolize stored energy (fat) into usable energy, so if your liver is busy taking on some or all of the workload of your kidneys, it cannot burn fat. No matter how many calories you count or how much cardio you do, without enough water your body cannot burn fat.
This is why, when you are dehydrated, you are lethargic and/or feel hungry. Your body is looking desperately for a source of energy, so instead of eating more or sitting on the couch, drink a full glass of water and let your body burn your fat for energy.
How much is enough?
The simplest way to calculate your intake is to divide your weight (in lbs) in half, and drink that many ounces. (Example: a 140-lb woman should drink 70oz.) On particularly strenuous or hot/humid days, increase your intake by at least a glass or two.
IMPORTANT NOTE: Be sure to spread your water consumption out over the course of a day – too much water at one time can cause a very rare but serious condition called hyponatremia, or water intoxication. Typical symptoms include nausea, vomiting, headache, malaise, confusion, diminished reflexes, convulsions – seek medical attention IMMEDIATELY if any of these symptoms occur.
