Diet Doldrums - Is Dehydration the Culprit?
If you're stalled
on a weight loss plateau despite sticking to your diet,
the first thing to check is your water intake. Research
suggests that most Americans unknowingly suffer from
mild, chronic dehydration, and you could be one of them!
So why should you care? Because water
is an essential ingredient for your weight loss. In
fact, water is needed for a wide range of the body's
biochemical processes, but lets just look at what water
does for dieters:
Water is essential for your body to
metabolize stored fat into energy - so much so, that
your body's metabolism can be slowed by relatively mild
levels of dehydration. And the slower your metabolism,
the slower your weight loss (and the greater your fatigue),
until eventually your weight loss just crawls to a halt,
and you hit the dreaded diet plateau.
Water is a natural appetite suppressant.
In the hypothalamus, a region in your brain that controls
appetites and cravings, the control centers for hunger
and thirst are located next to each other, and there
tends to be some overlap. This has both advantages and
disadvantages for the dieter: on the down side, it means
that chronic mild dehydration can confuse these control
mechanisms, leading to feelings of hunger, rather than
thirst. But on a positive note, it means you can use
water to reduce your appetite. For example, in one University
of Washington study, drinking a glass of water reduced
nighttime hunger cravings for most of the dieters studied.
Water is an essential component of the
processes that enable muscle to contract. This means
that water helps to maintain muscle tone. Better muscle
tone means a better looking body, and isn't that what
dieting and weight loss is about?
Water also helps to prevent the sagging
skin that often follows weight loss - water plumps the
skin cells, giving the skin a younger and healthier
look.
Water helps rid the body of waste. During
weight loss, the body has a lot more waste to get rid
of, as a byproduct of all that metabolized fat. So adequate
water is essential to your health while dieting.
Water can even help with constipation.
When the body gets too little water, it siphons what
it needs from within, particularly from the colon. This
leads to constipation. But normal bowel function usually
returns with adequate water intake.
More generally, mild dehydration can
cause a number of health problems, in addition to your
diet plateau. The symptoms of mild dehydration can include:
-
- Headaches & feeling light headed,
as dehydration interferes with normal body processes,
including waste disposal.
- Fatigue, as the body's metabolism is slowed - mild
dehydration is probably the most common cause of daytime
fatigue.
- Hunger & cravings due to weakening of the thirst
mechanism
- Fluid retention as your body tries to hold on to the
water it already has
- Constipation, as the body works to conserve its internal
water sources
Not a pretty picture, is it? But once
you get your water in balance, you reach the "breakthrough
point", a concept pioneered by Dr. Peter Lindner,
a California obesity expert. Once you've reached the
breakthrough point, fluid retention eases, the liver
and endocrine system start to function more effectively,
you will start to regain your natural thirst and your
hunger cravings will be significantly reduced. And so
the end result of reaching and sustaining the breakthrough
point in your water balance is that your body is able
to metabolize fat more effectively.
So how much water should you drink daily,
for a healthy and 'adequate' intake? First, a couple
of basic principles:
1) The easiest way to tell if you are
drinking enough water is to monitor the color of your
urine: It should be clear or a very pale yellow in color.
(but note that some supplements and medications may
also affect your urine color).
2) Get in to the habit of drinking regular
and adequate amounts of water. Never wait to drink until
you're thirsty, because if you're feeling thirsty, then
dehydration has already started to occur!
Having said that, an adequate water
intake for a sedentary but normal-weight adult during
cool weather, is generally recognized as 8 x 8 oz glasses.
Note that you need additional water
in hot weather, when you lose more water through sweat.
You also need additional water when
you exercise. Athletes attempt to enhance their performance
by maintaining an optimal fluid balance while exercising,
estimated to require 6 to 12 oz of fluid at 15 to 20
minute intervals. Even if you're not concerned about
your athletic performance, you should consume a similar
amount of water when exercising, in order to maintain
adequate hydration.
And if you're overweight, you'll need
an extra glass of water for each 25 pounds overweight,
because the extra weight creates extra metabolic demand
But how do you manage to drink so much
water? A typical recommendation from the weight loss
experts is 3 glasses of water with every meal. That's
3 glasses with breakfast, 3 with lunch, and 3 with dinner.
Plus, of course, additional regular water between meals
when you're exercising or when its hot.
So if you're dieting, stalled on a weight
loss plateau, or suffering some of the classic symptoms
of dehydration, do, first of all, ensure that you have
an adequate water intake. It could be the 'missing ingredient'
in your diet regime.
