Bodybuilding Cyclic Ketogenic Diet
by by Ed Sturm
This article is being written for
those who are either only remotely familiar and totally unfamiliar
with ketogenic dieting. The information provided here is based solely
upon my own personal experiences as well as those of my wife. There
are no references from medical journals or mentions of specific case
studies. This is simply a real life testimony of what my wife and I
have experienced with regards to ketogenic dieting.
What is a Ketogenic Diet?
For starters, ketotenic dieting is based upon the removal of nearly
all carbohydrates from one's diet for a certain period of time. In the
absence of carbohydrates, the body will resort to stored fat as it's
primary fuel source. Stored fat is broken down into ketones which the
body then uses for energy. In order to enter this state of ketosis,
one's liver glycogen must be emptied. Ingested carbohydrates are
stored in the liver as glycogen, as well as in the muscles. When the
liver is depleted of glycogen, a state of ketosis is achieved. Ketones
are a by-product of fat burning, therefore while in a state of
ketosis, the body is burning stored fat as it's main source of fuel.
I'll bypass the explanation as to why this is such a positive
occurrence.
The object of a ketogenic diet is to deplete the liver of it's
glycogen stores as quickly as possible so that fat burning occurs.
This is done by severely restricting carbohydrates and eating only
sources of proteins and fats. On a Cyclical Ketogenic Diet (CKD)
carbohydrate restriction lasts for a total of 5-6 days at which time a
1-2 day carbohydrate loading phase begins. The CKD is essentially the
Ketogenic Diet for weightlifters, with the carbohydrate loading phase
designed to replenish Muscle Glycogen stores so that adequate weight
training may occur during the following week.
Many people have brought up the issue that a low carbohydrate diet
will cause lethargy and weakness. These people were not mentally
strong enough to make it through the first few days until they reached
a state of ketosis so they experienced the basic lethargy typically
associated with low carb diets. They also did not replace any of the
missing calories with fat which caused them to feel miserable due to a
lack of adequate calories. They didn't give themselves or the diet a
chance to adapt. Just like with anything else, there is a period of
adaptation.
This is not a low carbohydrate diet. It is essentially a NO
Carbohydrate diet. While on a LOW carbohydrate diet, enough carbs are
always eaten to avoid entering into a state of ketosis but not enough
carbs or total calories to maintain adequate energy levels. Dropping
the carbohydrate count further and raising the fat calories will allow
the body to enter ketosis and use ketones, or stored fat as fuel.
While in a state of ketosis, one feels energetic and does not
experience the general lethargy found with basic LOW carbohydrate
diets. Ketones also enable one to maintain regulated insulin levels
throughout the day which again will cause one to feel energetic. Below
we can see the difference between a basic low carb diet and the
Ketogeinc Diet.
Basic LOW Carb Diet:
- weakness
- lethargy
- low insulin levels
- constant hunger
- moderate fat burning
- muscle loss
- low fat intake
- excessively low total calories
Ketogenic Diet:
- energy
- workout intensity
- feelings of well-being
- full and satisfied
- high fat intake
- high level of fat burning
- minimal muscle loss
- total calories no more than 500 below maintenance
Clearly it is obvious which diet is more beneficial as far as fat
burning, retaining muscle and general feelings of well being. Plus,
with the ketogenic diet, you actually get to eat more food.
How it Works
Now don't get me wrong here. I am not trying to "sell" anyone on a
ketogenic diet and there is no product we are pushing here. This
article is simply to give people another option; one that my wife and
I have had a tremendous amount of success with. Ketogenic dieting is
not easy as eliminating carbohydrates from one's daily eating habits
is quite difficult. It requires structure, planning and dedication.
Many foods are carbohydrate laden that the average person is not even
aware of such as fruits and condiments. Basically, on a ketogenic diet
one eats meat and fish all day long. It does have it's advantages
though as normally restricted foods such as steak, whole eggs, pork
chops, pork skins, sausages, meatloaf, burgers (without the bun of
course) and salmon are not only permitted, but they are encouraged.
It is quite simple to slip up without even knowing it on this diet.
First, understand that even a minimal amount of carbohydrates will
shift your body right out of the ketosis/fat burning mode. This is a
diet that requires strict attention to detail and absolutely NO
cheating during the week. The cheating will come soon enough and
plenty enough on the weekends. There is no such thing as just a little
bite of that bagel of just one cookie. This diet works absolute
wonders as far as fat burning goes but it must be done properly or
results will be minimal at best.
Carb Depletion
During the carbohydrate depletion phase (during the week)
carbohydrate foods such as fruit, breads, grains, candies, cookies,
deserts, catsup, dressings, cereals, etc., etc. are not permitted at
all. One must check the label of everything to ensure that there are
no carbs. The key is to keep the daily carb count of 20-40 per day.
Some people even require less than 20 to achieve ketosis. This
basically allows you a total of roughly 4-8 grams of carbohydrates per
meal which would preferably come in the form of green vegetables.
Watch the dressings as they all have carbohydrates with the exception
of vinegar. The only condiments that you can be safe with are mustard
and regular, whole mayonnaise. (not low fat or light)
Workouts
While on a CKD, one must tailor their workouts to center around the
diet. The carb depletion would begin on Monday and between
Monday-Wednesday, the entire body would be trained with weights. In
other words, condense the workouts so that they are completed by
Wednesday. This will exhaust both your liver glycogen as well as your
muscle glycogen. Cardio may continue to be done all week. At the end
of the week, one would perform a grueling full body weight training
session after which time the carb loading would begin.
Carb Loading
The carbohydrate loading may last anywhere between 12-36 hours
although I feel it is best to minimize it to 12-18 hours. It consists
of basically a full day of cheating (but there are rules). You need to
consume carbohydrates in each meal ranging from 40-120, depending upon
the person. The protein stays high but fats must be limited or the
total calories will be too high and new fat will be stored. The idea
is refill muscle glycogen so that workouts may be performed with some
amount of intensity the following week. Fruits are to be avoided as
fructose will only refill liver glycogen which will prevent ketosis
from being reestablished until later in the week. After the carb load
is complete, the depletion phase begins again until the next weekend.
During the carb load period, any carbs may be eaten so long as the fat
is kept moderately low and there is no fructose (fruit sugar)
consumed.
Results
While on a CKD, it is quite common for users to experience total
fat loss of up to 2-3 pounds per week. Due to the carbohydrate cycling
and manipulation, one will experience weight fluctuations ranging from
2-10 pounds during the carb loading phase. Personally, I went from 10%
body fat to 5% in 8 weeks with minimal muscle loss while my wife went
from 20% to 15% in an astonishing five weeks. The keys are not
cheating at all during the week, knowing the nutritional content of
the foods you eat, maintaining structure and not overdoing it on the
weekends.
This article is intended to supply the reader with a basic
introduction to the principles of ketogenic dieting. There is much
more information available and I strongly suggest that prior to
starting a diet of this sort, the reader purchase one of the following
books listed below which will shed more light upon the subject. There
are additional variables such as vitamin and supplement information,
fiber consumption, additional ketogenic aids and potential dangers
which need to be addressed prior to beginning a ketogenic diet.
