(From Classic X, March 17, 1999)
Note: This article is packed with pertinent guidelines on the importance of drinking a large amount of water each day and how doing so facilitates fat loss and muscle building. In fact, the material has been widely distributed (without my permission) throughout the Internet. The concept of ice-cold water supplying a positive, calorie-burning effect which Ive applied for more than 15 years has been recently confirmed by German scientists (see Boschmann, Michael, et al, "Water-Induced Thermogenesis," Journal of Clinical Endocinology & Metabolism 88: 6015-6019, 2003).

Americans, not by the thousands but by the millions are getting fatter each year. If you vacationed in Florida this past summer, then you know what Im talking about.
Have you ever seen so many overweight and extremely obese people at the beach? Or how about the profiles of all those family fun-seekers who, with ice creams in one hand and hot dogs in the other, crowd the major theme parks? They seem to come in three sizes: fat, fatter, and, even fatter!
Oh sure, you do see a few lean individuals at the beach and at the theme parks. But I guarantee you 99 percent of these people are 18 years of age or younger. You have to walk, and walk, and walk some more to find a single person in great shape, over the age of 40.
Im not going to present my lengthy philosophy about why and how Americans should decrease their dietary calories to lose fat and intensify their exercise to build muscle. Youve probably heard it several times already.
What I want to describe is something that is much simpler to apply than dieting and exercising. That something is Superhydration, or the drinking of at least one gallon of ice-cold water each day.
Superhydration, practiced properly, can make a valuable contribution toward combating and conquering obesity in the United States and throughout the world.
I didnt invent the concept of drinking large amounts of cold water, but I was the first person to popularize it by connecting it to my fat-loss courses. Also, I was probably the first author to provide specific directions on why, how, and when to consume the fluid.
I did have a lot of help, however. Dr. Harold Schendel, my major nutrition professor at Florida State University, hammered me with the value of drinking lots of water in losing fat. Brenda Hutchins, who worked with me on many recipes in my early fat-loss studies, made major contributions. Connie May, who trained many research subjects at the Nautilus headquarters in Dallas, Texas, had several great ideas concerning water drinking. And so did Terry Duschinski, the owner of a personal training center in DeLand, Florida.
Superhydration began to formalize in 1985 as I supervised three large groups of subjects through the Nautilus diet program at Joe Cirullis fitness center in Gainesville, Florida. I instructed the groups to drink 64 ounces of water a day. Back then, I didnt understand fully the ice-cold concept so the fluid could be consumed at any temperature. This research was published in a major book called The Nautilus Diet.
When Nautilus Sports/Medical Industries relocated the headquarters in 1987 to Dallas, Texas, I continued to research and refine these ideas. These findings were published in three books: The Six-Week Fat-to-Muscle Makeover, 32 Days to a 32-Inch Waist, and Hot Hips and Fabulous Thighs. By now, my water recommendations were up to 128 ounces a day and I was beginning to explore the advantages of consuming cold water.
After three years in Dallas, I returned to the Gainesville Health & Fitness Center, and from 1990 through 1997, I developed four more courses of action: Two Weeks to a Tighter Tummy, Living Longer Stronger, Body Defining, and A Flat Stomach ASAP. During these courses, I proved that chilled water was a significant boon to the fat-loss process. I actually had some of my subjects progress up to two gallons of fluid a day. Interestingly, the individuals in my programs who consistently drank the most cold water tended to lose the most fat.
Over the last dozen years, 549 women and 271 men have officially completed one of my routines that involved Superhydration. Not a single one of these participants ever suffered from any major medical problem as a result of drinking at least one gallon of ice-cold water each day for the duration of the course.
The reason I mention this fact is because Superhydration has been criticized as problematic or dangerous. "People cant drink that much water without getting sick," noted a medical advisor, who vetoed a review of one of my books from being published in a large newspaper.
"They not only can drink that much water," Ive discovered, "but they thrive on it."
Lets take a closer look at why your body thrives on water.
The human body is from 50 to 65 percent water. But not all body components have the same water percentage. Your blood, for example, is 90 percent water, your brain is 85 percent, your muscle is 72 percent, your skin is 71 percent, your bone is 30 percent, and your fat is 15 percent.
As your body experiences dehydration, you feel it first in those systems that contain the most water. For example, you lose your mental alertness and you suffer from overall muscular weakness. The last component that dehydration affects is your fat. Thats why excessive sweating makes almost no dent in reducing your body-fat percentage.
Men have more water in their bodies than women, primarily because men have more muscle mass and less fat than women. A lean man with a body weight of 180 pounds may have 14 gallons of water in his system. A gallon of water (128 ounces) weighs approximately 8 pounds, so simple multiplication (8 x 14)
reveals that 112 pounds of this mans body is water.
You may not think of water as food, but its the most critical nutrient in your daily life. You can only live a few days without it. Every process in your body requires water. For instance, it:
• Acts as a solvent for vitamins, minerals, amino acids, and glucose.
• Carries nutrients through the system.
• Makes food digestion possible.
• Lubricates the joints.
• Serves as a shock absorber inside the eyes and spinal cord.
• Maintains body temperature.
• Rids the body of waste products through the urine.
• Eliminates heat through the skin, lungs, and urine.
• Keeps the skin supple.
• Assists muscular contraction.
Water contributes to so many functions that most people take it for granted. At the end of a long workday, maybe you have a headache. Plus, your eyes are irritated, your back hurts, and your entire body has a dull numbness. You blame it on stress and lack of sleep over the weekend.
Maybe youre right. But more likely, youre simply suffering from partial dehydration.
Perhaps youve had several cups of coffee for breakfast, a high-fat lunch with more coffee or maybe an alcoholic drink or two, and spent the rest of your time breathing air-conditioned or heated air at work all of which has left your body, and most of its systems, dry and parched. Unless youve been drinking water throughout the day, dehydration is your problem.
If you are attuned and sensitive enough to your bodys signals, you should be able to recognize some of the early warnings of dehydration:
• Flushed skin
• Blurred vision
• Muscle weakness
These warning signs merit your attention. Unfortunately, most people never realize that they spend most days in a state of partial dehydration.
Although thirst is an important warning sign, many people seem to be desensitized to the signal. Some people, especially adults over 40, may actually have a decreased sensation of thirst.
Large amounts of water facilitate the fat-loss process in a number of ways:
Your kidneys require abundant water to function properly. If your kidneys do not get enough water, your liver takes over and assumes some of the functions of the kidneys. This diverts your liver from its primary duty to metabolize stored fat into usable energy.
If your liver is preoccupied with performing the chores of your water-depleted kidneys, it doesnt efficiently convert the stored materials into usable chemicals. Thus, your fat loss stops, or at least, plateaus. Superhydration accelerates the metabolism of fat.
Lots of water flowing over your tongue keeps your taste buds cleansed of flavors that might otherwise trigger a craving. Furthermore, water keeps your stomach feeling full between meals, which can help take the edge off your appetite.
Heres a little-understood fact: As much as 85 percent of your daily heat loss emerges from your skin. Heat emerging from your skin is important because another word for heat is calories, and another word for calories is fat. Thats right, most of your fat is lost through your skin in the form of heat. Anyway, the remaining 15 percent of that heat loss is divided between warm air coming from your lungs and warm fluid being passed out through the normal urination process.
Superhydration can double, triple, or even quadruple your urine production. As a result, youll be able to eliminate more heat. Remember, inside your body, fat loss means heat loss. So get used to going to the bathroom more frequently than normal.
Have you ever wished for a food that supplies negative calories? Lets say such a food exists and it contains a minus 100 calories per serving. Anytime you feel like a piece of chocolate cake or a donut, all you have to do to compensate is simply follow the sweet with two servings of the negative-calorie food. Presto plus 200 calories and minus 200 calories yields 0 calories. While no negative-calorie food exists in science ice-cold water has a similar, but smaller, effect inside your body.
When you drink chilled water, which is about 40-degrees Fahrenheit, your system has to heat the fluid to a core body temperature of 98.6 degrees. This process requires almost 1 calorie to warm each ounce of cold water to body temperature. Thus, an 8-ounce glass of cold water burns approximately 8 calories, or 7.69 to be exact. Extend that over 16 glasses, 128 ounces, or one gallon and youve generated 123 calories of heat energy, which is significant. Theres real calorie-burning power in cold water.
A professor of biology from the University of Florida added to my understanding of the cold-water connection when he pointed out that melting ice and a burning candle both require the transfer of heat. They simply modify their forms. The ice changes from solid to liquid, and the candle from solid to gas. Both transfers, or changes, involve heat.
When deprived of water, your system pulls cellular fluid from your lower intestines and bowel creating hard, dry stools. One of the big roles of water is to flush waste from the body. This is a substantial task during fat metabolism because waste tends to accumulate quickly. Superhydration tends to make people more regular and consistent with their bowel movements, which is helpful to the overall fat-loss process.
How do you drink a gallon of ice-cold water a day? "With great difficulty," you may reply. Although such a recommendation may sound difficult, in fact, it only presents a few minor problems such as how, when, and where. Each of these problems can be solved with some intelligent planning.
One secret is to not drink the water, but to sip it. Get yourself one of those 32-ounce plastic bottles, the kind that has a long straw in the top. Ive found that most people can consume water easier with a straw than trying to gulp it down the standard way with a glass. Also, while youre checking out various bottles, select one that is insulated. The insulation will keep your fluid colder for a longer time.
Another tip is to spread your water drinking throughout the day. Theres a useful guide that I worked out for more than 100 men who went though my six-week, fat-loss plan in Living Longer Stronger on page 140.
Youll notice on this plan that after Week 1, the men add 16 ounces of water each week to their starting level of 128 ounces per day. During Week 6, the recommendations are up to a daily consumption of 208 ounces, or 1 5/8 gallons. This schedule is just an example. Unless youre involved in the other aspects of the Living-Longer-Stronger program, simply stick with the Week 1 guidelines.
Its important to sip from 75 to 80 percent of the water before 5:00 P.M. The early drinking of most of the water eliminates the need to get out of bed during the night and visit the bathroom.
You sip water everywhere you go during the day because you know how to plan ahead. Once again, you need a 32-ounce, insulated, plastic bottle. Okay. But what about refilling the bottle, the ice, and all that hassle of keeping count of the ounces?
The really motivated people invest in a two-gallon thermos jug. First thing in the morning, they fill the large jug with ice and water. Then, they draw off their initial 32-ounces of fluid into their insulated bottle and start sipping. As soon as the bottle is empty, its refilled from the thermos jug. When they leave home each day, they carry both the thermos jug and the smaller bottle with them. That way they always have access to their chilled water. When they return home that night, they wash the jug and the bottle and prepare for the next morning.
A great way to keep count of the bottles and ounces is to place rubber bands around the middle of the bottle equal to the number of bottles of water you are supposed to drink. Each time you finish 32 ounces, take off a rubber band and put it into your pocket.
There is a difference between plain water and other beverages that contain mostly water. Those mostly water fluids such as soft drinks, coffee, tea, beer, and fruit juices contain sugar, flavors, caffeine, and alcohol. Sugar and alcohol add calories. Caffeine found in coffee, tea, and many soft drinks stimulates the adrenal glands and acts as a diuretic. Rather than superhydrate the system, caffeine-containing beverages actually dehydrate the body. You should keep such beverages to a minimum.
The only recommended flavoring for water is a twist of lemon or lime. Even so, most of the people who like lemon or lime eventually get to the level where they prefer their water plain with nothing added.
In general, the United States has one of the safest water supplies in the world. Chances are high that your communitys tap water is fine for drinking. Furthermore, research shows that bottled water is not always higher quality water than tap water. The decision to consume bottled water or not is usually one of taste.
If you dislike the taste of your tap water, then drink your favorite bottled water. Just be sure to check the label carefully for unwanted additives. If you have no problems with your citys water supply, then save some money and consume it.
Its possible to drink too much water, but its highly unlikely that you would ever do so. In the medical literature, drinking too much water leads to a condition know as hyponatremia. Hyponatremia most often occurs in athletes involved in triathlons and ultrmarathons. A few of these athletes consume many gallons of water during the course of these unusually long competitions, and because of the continuous activity they dont or cant stop to urinate. Thus, they impede their normal fluid-mineral balance and actually become intoxicated with too much water. Such a condition, however, is rare.
Ive never observed anything close to intoxication happening with any of my participants, and some of them consume two gallons of water daily. Of course, they also have no trouble urinating frequently.
Note: Anyone with a kidney disorder or anyone who takes diuretics should consult a physician before making modifications of his or her water consumption.
If you have more than 5 pounds of fat to lose, then Id suggest that you get involved with Superhydration through one of my books. Both Living Longer Stronger and A Flat Stomach ASAP have all the latest recommendations incorporated into their week-by-week rules which include eating and exercising plans.
On the other hand, if you only have a few pounds of fat to remove, or if your are already in lean condition, or if you just want to give Superhydration an informal trial for whatever reason, then here are the most efficient guidelines to utilize:
1. Purchase a 32-ounce, insulated, plastic bottle to sip your water from.
2. Start by sipping one gallon, or 128 ounces, of water a day. Do not go higher than 128 ounces per day for this informal trial period.
3. Drink most of the water before 5:00 P.M.
4. Keep the water ice cold. Remember, each ounce of 40-degree Fahrenheit water requires approximately 1 calorie to warm it to a core body temperature of 98.6 degrees.
5. Apply the above recommendations for at least 14 days.
Expect to feel more energetic, less fatigued, smoother skinned, and more satiated (from a nutritional standpoint) by the end of the first week. Anticipate being a little leaner by the end of the second week.
If you keep the Superhydration routine intact for a full month, you just may get healthily hooked for a long time.
During this brief process, youll experience some of your bodys quest, thirst, and fulfillment for water: large amounts of it. Youll realize that, for years and years, what youve been calling hunger was really an inner cry for more water.
Listen closely to your body. It will reward you when it gets what it needs.
Superhydration has worked for thousands of people. It will work for you by improving your well being both on the inside and the outside of your body.
It will definitely help you lose fat and live leaner longer.
Decide today to make Superhydration a salient aspect of your daily lifestyle.
Lets drink to it.
WATER: on the rocks . . . straight up . . . and with a straw.
Make it a double!
