Common Myths About Dieting
Myth #1: High-protein/low-carbohydrate diets are a healthy way to lose
weight.
Fact: The long-term health effects of a high-protein/low-carbohydrate diet are
unknown. But getting most of your daily calories from high-protein foods like meat,
eggs, and cheese is not a balanced eating plan. You may be eating too much fat
and cholesterol, which may raise heart disease risk. You may be eating too few
fruits, vegetables, and whole grains, which may lead to constipation due to lack of
dietary fiber. Following a high-protein/low-carbohydrate diet may also make you
feel: nauseous, tired, and weak.
Eating fewer than 130 grams of carbohydrate a day can lead to the buildup of
ketones (partially broken-down fats) in your blood. A buildup of ketones in your
blood (called ketosis) can cause your body to produce high levels of uric acid,
which is a risk factor for gout (a painful swelling of the joints) and kidney stones.
Ketosis may be especially risky for pregnant women and people with diabetes or
kidney disease.
Myth #2: Natural or herbal weight loss products are safe and effective.
Fact: A weight loss product that claims to be "natural" or "herbal" is not
necessarily safe. These products are not usually scientifically tested to prove that
they are safe or that they work. For example, herbal products containing ephedra
have caused serious health problems and even death. Newer products that claim
to be ephedra-free are not necessarily danger-free, because they may contain
ingredients similar to ephedra.
Myth #3: Fast foods are always an unhealthy choice and you should not eat
them when dieting.
Fact: Fast foods can be part of a healthy weight loss program with a little bit of
know-how.
Tip: Avoid supersize combo meals, or split one with a friend. Sip on water or
nonfat milk instead of soda. Choose salads and grilled foods, like a grilled
chicken breast sandwich or small hamburger. Try a "fresco" taco (with salsa
instead of cheese or sauce) at taco stands. Fried foods, like French fries and fried
chicken, are high in fat and calories, so order them only once in a while, order a
small portion, or split an order with a friend. Also, use only small amounts of high-
fat, high-calorie toppings, like: regular mayonnaise, salad dressings, bacon, and
cheese.
Myth #4: Skipping meals is a good way to lose weight.
Fact: Studies show that people who skip breakfast and eat fewer times
during the day tend to be heavier than people who eat a healthy breakfast and eat
four or five times a day. This may be because people who skip meals tend to feel
hungrier later on, and eat more than they normally would. It may also be that
eating many small meals throughout the day helps people control their appetites.
Tip: Eat small meals throughout the day that include a variety of healthy, low-fat,
low-calorie foods.
Myth #5: Lifting weights is not good to do if you want to lose weight,
because it will make you "bulk up."
Fact: Lifting weights or doing strengthening activities like push-ups and
crunches on a regular basis can actually help you maintain or lose weight. These
activities can help you build muscle, and muscle burns more calories than body
fat. So if you have more muscle, you burn more calories—even sitting still. Doing
strengthening activities 2 or 3 days a week will not "bulk you up." Only intense
strength training, combined with a certain genetic background, can build very
large muscles.
Tip: In addition to doing at least 30 minutes of moderate-intensity physical activity
(like walking 2 miles in 30 minutes) on most days of the week, try to do
strengthening activities 2 to 3 days a week. You can:
lift weights, use large rubber bands (resistance bands), do push-ups or sit-ups,
and do household or garden tasks that make you lift or dig.

Fats
The fats normally occur in animal and
vegetable tissue. Fats are designated as saturated
or unsaturated, depending on whether the chemical
bonds between the carbon atoms of the fat
molecules contain all the hydrogen atoms they are
capable of holding (saturated) or have capacity for
additional hydrogen atoms (unsaturated).
Saturated fats generally are solid at room
temperature; unsaturated and polyunsaturated fats
are liquids. Unsaturated fats may be converted to
saturated fats by adding hydrogen atoms in a
process known as hydrogenation. When saturated
solid fats are added to the diet, the amount of
cholesterol in the blood increases, but when liquid,
unsaturated fats or oils replace solid fat, the amount
of cholesterol decreases.
The American Heart Association recommends
restricting the total fats in a diet, reducing the
consumption of cholesterol-rich foods, such as milk
and butter, replacing saturated fats with unsaturated
fats, and limiting the intake of trans fats. Sterols are
a compound containing a multi-ring (steroid)
structure and a hydroxyl group (-OH).
Polyunsaturated fatty acids (PUFA) are primarily
found in vegetable oils and fish sources. Omega-6
PUFA is derived from vegetable oils and are liquid
at room temperature. They include corn, sunflower,
safflower, soybean, and sesame oils. Salad
dressing, margarine, and mayonnaise containing
these oils are therefore high in polyunsaturated fat.
Omega-3 PUFA is found primarily in fish.
Monounsaturated fats are derived from plant
sources. High amounts are found in olive, canola
(rapeseed), and peanut oil as well as avocados,
and certain nuts. Monounsaturated and
polyunsaturated fats do not increase serum
cholesterol or LDL levels and are associated with a
reduced risk of heart disease. The foods in our diet
with the highest energy density for fat are salad oils,
butter, margarine, and mayonnaise. All of these
foods contain almost 100% of energy as fat.
Well, that right there is good enough on fats. I
could ramble on for even longer, but lets get to why
a bodybuilder should incorporate fats; (unsaturated)
into their diet. First, I am going to give you a brief
overview of why we need EFA's, or Essential Fatty
Acids in our diet. First, humans can't produce
omega-3 and omega-6 fatty acids; we get them only
by ingesting them.
These fatty acids are essential for us to eat
because they participate in the immune processes
and vision, help form cell structures, and aid in the
production of hormone-like compounds. Because
we must get linoleic acid (omega-6) and
alpha-linolenic acid (omega-3) from foods, they are
called essential fatty acids, like I mentioned up
above. If we don't get enough of these, our skin will
be flaky and itchy, and diarrhea and other symptoms
will occur. These fats provide energy for the body;
they store energy, insulate and protect the organs,
and transport fat-soluble vitamins.
Now you may ask, why do bodybuilders need
more EFA's? Well, here is why you need more,
especially if you trying to bulk up. If you are bulking,
and only getting 15% fat from the diet, you better up
it to 25-30%; here is why. A diet consisting of 30%
EFA's can produce a better anabolic effect and
higher nitrogen retention, than a high protein low
carb low fat diet.
If you are having trouble consuming more
calories in the day, try adding a little more fat. One
Tablespoon of flax oil, or canola oil gives you 120
cal. If you are eating 3000 cal a day, you should be
getting 83-100g of fat per day. This is for those of
you who are bulking. What is also good about
adding more EFA's to the diet is all of the health
benefits. Just think, at the same time you are getting
big, you are also staying healthy.

Water
Our bodies are estimated to be about 60 to 70%
water. Blood is mostly water, and our muscles, lungs, and
brain all contain a lot of water. We need to drink water
because water is needed to regulate body temperature
and to provide the means for nutrients to travel to all our
organs. Water also transports oxygen to our cells,
removes waste, and protects our joints and organs.
Signs of Dehydration
We lose water through urination, respiration, and by
sweating. If you are very active, you lose more water than if
you are sedentary. Diuretics such as caffeine and alcohol
result in the need to drink more water because they trick
our bodies into thinking we have more water than we
need. Symptoms of mild dehydration include chronic
pains in joints and muscles, lower back pain, headaches,
and constipation. A strong odor to your urine, along with a
yellow or amber color indicates that you are not getting
enough water. (Note that riboflavin, a B Vitamin, will make
your urine bright yellow.) Thirst is an obvious sign of
dehydration and in fact, you need water long before you
feel thirsty.
How Much Water do we Need to Drink?
A good rule of thumb is to take your body weight in
pounds and divide that number in half. That gives you the
number of ounces of water per day that you need to drink.
For example, if you weigh 160 pounds, you should drink at
least 80 ounces of water per day. If you exercise you
should drink another 8-ounce glass of water for every 20
minutes you are active. If you drink coffee or alcohol, you
should drink at least an equal amount of water. When you
are traveling on an airplane, it is good to drink 8 ounces of
water for every hour you are on board the plane. If you live
in an arid climate, you should add another 2 servings per
day. As you can see, your daily need for water can add up
to quite a lot. The best source of water is plain, pure
drinking water. Sodas have a lot of sugar in them and
aren't a good source, so if you drink them, they don't count
towards your daily amount. Herbal teas that aren't diuretic
are fine. Sports drinks contain electrolytes and may be
beneficial, just look out for added sugar and calories that
you don't need.

Carbohydrates
Carbohydrates are sugars: some are simple
and some are complex. Simple carbohydrates are
natural sugars that come from items such as
vegetables, fruits, honey and maple. Complex
carbohydrates are made up of complex chains of
sugars and are known as starches and fiber. The
body is able to easily digest the simple sugars but
complex sugars are harder to digest. The body
needs and is able to process some complex
sugars such as fiber.
'Carbohydrates are needed for the body to
survive:' this is a misconception about the weight
gain involved in consuming carbohydrates. When
carbohydrates are consumed with other fattening
foods or consumed in quantities more than the
body could withstand, then the body would convert
extra into fat.
The daily intake of carbohydrates has no set
limit, but according to the government the daily
intake should be fifty percent of the daily calories
consumed per day, should come from
carbohydrates such as grains, vegetables, and
fruits. The body turns these carbohydrates into
glucose, which can be stored in the body’s tissues
and muscles. Regular exercise can help the body
store glucose within the muscles.
Having a healthy body is essential but having
stored glucose in the muscles insuring the ability
of endurance. This is particularly important for
athletes and people with high physical
occupations.
Foods preparing meals remember some
important foods for carbohydrates; breakfast could
consist of a bowl of whole-grain cereal, a slice of
toast, grapefruit or a six-ounce glass of orange
juice, one bowl of cooked whole-grain cereal, one-
fourth cup raisins. For lunch you could try two slices
whole-grain bread, one large bowl of salad with
lettuce, green pepper, cucumber and tomato, and
one apple or a three bean salad consisting of
chickpeas, red kidney beans and string beans, one-
half cup rice and a banana.
Dinner could be a baked potato, one-half cup
broccoli; one-half cup carrots, one peach and two
oatmeal cookies. These are suggestions that will
allow you to consume a healthy amount of
carbohydrates and make the body healthier.

Proteins
Protein constitutes three-fourths of our body tissue
(excluding the water). Muscles, organs, antibodies,
enzymes, and some hormones are largely composed
of proteins. Other key body functions include tissue
repair, fluid balance, blood clotting, and vision.
Protein is not a single substance but numerous
chemical combinations. The basic structure of protein
is amino acid chains, which can form many different
configurations and can combine with other substances.
There have been 22 amino acids identified in the
protein of the human body. Proteins are constantly
broken down in the body. Most of these are reused by
the body. However, some need to be replaced. There
are nine that are considered to be essential. These
cannot be manufactured by the body and must be
supplied by the diet.
The average protein requirement for women is 50
grams per day and 60 grams per day for men. Meat and
other animal products are the most readily available
sources of complete protein. The protein content of
cooked meat and dairy products is between 15% and
40%. In contrast, cooked cereals, beans, lentils, and
peas range from 3% to 10%. Vegetarians can get
enough protein if they eat a well-balanced diet of grains
and vegetables, like brown rice, whole wheat pasta, soy
products, and beans.
What are good sources of protein?
Eggs, milk, fish, beef, peanuts, oats, rice, whole
wheat products, corn products, soybean products,
sesame seeds, peas, and beans are all good sources
of protein.
Do high protein diets help people gain muscle mass?
You need adequate protein to build muscle, but if
10-15% of your diet is protein, you are getting enough to
maintain and add new muscle and tissue. It is a myth
that super-high protein diets assist in increasing lean
muscle mass or give athletes a competitive edge. Any
excess protein will be stored as fat, not muscle. Plus,
the conversion of large amounts of protein to fat puts
stress on both the kidneys and the liver.
