Are the extreme dehydration techniques practiced by competitive bodybuilders healthy -- or even necessary? In his memoir
I’m Here to Win, two-time Ironman World Champion Chris McCormack includes a section titled “How Bodybuilders Helped Me Win Kona.” In the section, McCormack describes his battle with cramping, overheating and severely hampered performances at triathlon’s main event on the Big Island. Even though McCormack won the Championship in 2007, he was unable to repeat in both 2008 and 2009. Frustrated with his lack of progress, he turned to sources outside of triathlon for nutrition advice, settling on bodybuilding because “pro bodybuilders become like pharmacists -- experts when it comes to nutrition, muscle size and health.”
Hydration is one of the biggest issues bodybuilders manage when competing. Muscle size is dependent partly on water content, so a hydrated muscle is a big muscle. However, competitors also want to avoid retaining any extra water, which will prevent their skin from appearing “tight” onstage. Too much water and the bodybuilder will look bloated and soft; too little water and the bodybuilder could cramp and struggle to induce a pump in his muscles. McCormack learns all of this from a chance encounter with a former Mr. France who told him about the difference in hydrating at the muscular-cellular level and hydrating at the blood-plasma level. “What tends to happen
is that theis that the blood gets full of water, which is good because you feel like you're hydrated, and you pee a lot,” McCormack writes. “But the osmosis across the cell wall doesn’t happen as quickly without the high intake of electrolytes, because your muscles protect themselves. They are very careful of what they take in.” The bodybuilder tells McCormack about a complex hydration strategy, which specifies timelines and electrolyte supplements to hydrate McCormack’s muscles, but not his blood plasma. McCormack tried an adapted version of the routine and won the 2010 Ironman World Championship, without a single cramp. In his memoir, he attributes his success in part to the bodybuilder’s advice. This blog post, inspired by SaltStick retailer
Sand & Steel Fitness, is not about McCormack’s journey to recapturing the World Championship title. If you want to learn more about that, you can read his memoir. Instead, it is about the advice coming from McCormack’s bodybuilding acquaintance. Bodybuilders are well-known for manipulating both body fat and water content in preparation for a competition. Yet as the research and historical evidence shows, the traditional approach is both unhealthy and -- unless an athlete is using unnatural methods to prepare for competition such as anabolic steroids -- not even useful.

acquaintance. Bodybuilders are well-known for manipulating both body fat
and water content in preparation for a competition. Yet as the research

The traditional approach
Bodybuilding.com provides a timeline
for bodybuilders looking to compete as lean as possible, including
strategies ranging from sodium loading/deloading to red wine-induced
urination. Other resources offer similar tactics for reducing weight
prior to competition, but all look fairly similar in that they
incorporate extreme steps toward dehydrating the athlete.
Some bodybuilders have become so obsessed with removing excess water
that they move beyond red wine and saunas to turn to chemical means. An article
titled “Diuretics in Bodybuilding: The Good, the Bad, the Tragic”
describes the great lengths some athletes will go before a competition.
“While athletes appear to be at the highest level of physical fitness
and health while on stage, they are actually often on the brink of very
serious health issues due to lack of hydration and electrolyte
imbalances caused by the lack of bodily fluids,” the article describes.
Many of these hydration imbalances are the result of an athlete
consuming diuretics, which induce urination. But extreme dehydration can
cause equally extreme problems inside the body, and several
bodybuilders have either died or been hospitalized due to cardiac arrest
or liver failure resulting from electrolyte imbalances. Famous examples
include Mohammed Benaziza, who died in 1992 and Albert Beckles, who
died but was resuscitated by paramedics in 1988. Physicians found out
afterwards that both had taken diuretics before their shows.
Death may be the most serious consequence, but other side
effects of bodybuilding’s dehydration methods include a drop in blood
pressure, thickening of the blood (due to lack of fluids), fainting,
renal failure and cramping due to electrolyte imbalances.
Endurance sports, of course, have their own share of horror stories
relating to dehydration (or more commonly, overhydration resulting in hyponatremia).
The takeaway from both sports is the same: Do not play with the body’s
need for appropriate levels of water and electrolytes.
Athletes in either sport will counter-argue and agree that completing a
long-distance triathlon or getting lean enough to compete onstage is not
ideal for the body (physically, mentally, hormonally), which is why
competitions only happen a few times each year. It is true that some
level of physical stress must be accepted in order to achieve
world-class results. For instance, extreme low body-fat levels results
in dramatically low testosterone levels (International Journal of Sports Physiology and Performance, 2013), which return to normal after a bodybuilding competition ends and competitors return to a healthier body fat percentage.
However, when an athlete must be carried offstage because of
cramping or ends up hospitalized due to cardiac arrest, something has
gone wrong. This has caused some members of the bodybuilding
community to question whether the traditional methods of preparation are
still appropriate for the sport.
Is dehydration worth it?
In Ironman Magazine, columnist Dave Goodin addresses dehydration practices in a 2011 article.
His conclusion is that for a drug-free athlete, dehydration is not
necessary, and in fact, could achieve a negative outcome: “Dehydration
is very unhealthful and because it makes drug-free people look worse
instead of better.”
Goodin provides two reasons why dehydration has been overhyped in the
industry.
The first reason is that dehydration practices arose in an era before anabolic steroids were deemed illegal.
Before the late 1980s, steroids were common practice among bodybuilders
because their use had not been restricted by either federal or state
law. A side effect of steroid use is water accumulation outside of
muscle cells, and to counteract this, bodybuilders before the 1990s
commonly practiced dehydration methods to remove this extra water before
a competition. After steroid use was banned within the industry, the
practice continued, simply due to momentum. “If you are not taking any
bodybuilding drugs, there’s no reason to dehydrate your body for a
competition, photo shoot or any other event at which you want to look
lean and muscular,” Goodin writes.
The second reason is that among fitness circles, the phrase
“you’re just holding water” is often used as an excuse for excess body
fat. “Water retention is temporary,” Goodin writes. “Unless you have kidney issues, the
will be gone in no more than 24 to 36 hours. If the softness that is
being considered ‘holding water’ is there every day, it’s not water but
fat that you still need to lose.”
The proper approach to competition, as described by Goodin, is to cut
body fat to as little as possible and avoid foods that cause water
retention, such as high sodium foods or foods that contain allergens in
the final days before the competition. Nothing more. “On contest day I
always have water with me and drink anytime I’m thirsty,” Goodin writes.
“My advice is to be well hydrated and healthy.”
As a reference, Goodin has won nine international titles in natural bodybuilding.
Additional research has found similar conclusions to Goodin’s anecdotal evidence. A 2015 study
tracked a 21 year-old amateur bodybuilding competitor in his efforts to
improve body composition without using any of the traditional measures
of dehydration, periods of prolonged fasting, severe caloric
restriction, excessive cardiovascular exercise and inappropriate use of
diuretics and anabolic steroids. For 14 weeks, the athlete was
instructed to follow a program that looks surprisingly normal. The
elements included:
- Consuming a variety of foods;
- Not neglecting any macronutrient groups;
- Exercising regularly but not excessively; and
- Incorporating rest days into his conditioning regime.
This resulted in a loss of nearly 26 pounds and a 13 pound loss of pure
body fat. The study does not list more specific results (or competition
outcomes), but it does remark that the athlete’s mood was stable
throughout the process. “This intervention shows that a structured and
scientifically supported nutrition strategy can be implemented to
improve parameters relevant to bodybuilding competition and importantly
the health of competitors, therefore questioning the conventional
practices of bodybuilding preparation,” the study’s authors conclude.
Another study from 2014
concluded that “alterations in nutrient timing and frequency appear to
have little effect on fat loss or lean mass retention,” and “the
practice of dehydration and electrolyte manipulation in the final days
and hours prior to competition can be dangerous, and may not improve
appearance.”
It is worth noting that the two studies just mentioned deal exclusively
in the realm of natural bodybuilding, or bodybuilding without the
assistance of anabolic steroids. This more or less restates Goodin’s
original point that dehydration before a competition is only useful when
the athlete has been using non-natural methods in training.

In the end, what is useful?
Compared to the environment twenty years ago, professional triathletes
use fewer extreme techniques in training and racing, such as obtaining
dangerously-low body fat levels or “getting to the finish line at all
costs.” Modern exercise science has confirmed the risks of forcing the
body through such high levels of stress. Today’s athletes are willing to
take the risk only if success is likely, and while it is not as
spectator-friendly, it is much safer.
Bodybuilding has also moved in a more natural direction; “natural
bodybuilding” has even become a stand-alone competitive category. As the
studies above indicate, cutting body fat to low levels can be achieved
through diet and exercise. During competition, there is no need for
radical dehydration techniques, and athletes can follow normal hydration
protocol:
-
Consuming adequate amounts of all key electrolytes: The
body needs sodium for a variety of physiological processes, but also
potassium, calcium and magnesium. A majority of U.S adults do not
consume the recommended daily amount of magnesium, which is likely why
bodybuilders are often advised
to take magnesium supplements leading up to competition. Low magnesium
levels, in particular, have been correlated with increased cramping,
which is a bodybuilder’s enemy onstage.
-
Ensuring a proper balance among key electrolytes:
Bodybuilders are often told to cut sodium in the days before a
competition to avoid water retention. However, as we have discussed many
times on our blog, the ratio
of electrolytes is more important than the absolute amount consumed. A
diet high in potassium obtained from fruits and vegetables will help
reduce bloating due to water retention, and extreme reductions of sodium
are not necessary.
Extremes are seldom healthy or even useful, and success onstage
(or in a race) is much safer to achieve through discipline, consistency
and hard work. Last-minute adjustments may work in the
short-term, but are quite detrimental to the athlete’s health. As Goodin
writes, “Don’t fall victim to confusing body fat with ‘holding water,’
and don’t become a casualty of dehydration.”
Important Note: The above should not be construed as medical advice.
Contact your physician before starting any exercise program or if you
are taking any medication. Individuals with high blood pressure should
also consult their physician prior to taking an electrolyte supplement.
Overdose of electrolytes is possible, with symptoms such as vomiting and
feeling ill, and care should be taken not to overdose on any
electrolyte supplement.
