Research
proves that pomegranate is one of the most concentrated sources of
antioxidants. Studies have also proven
that key compounds in pomegranate can do something no one thought possible - reverse
the process of atherosclerosis (arterial plaque buildup that is the main
cause of heart disease and heart attack!).
These studies indicate that pomegranate provides
protection against and actual reversal of atherosclerosis by restoring artery
health, lowering blood pressure, and protecting low-density lipoprotein (LDL)
from oxidation.
Pomegranate also fights several of forms of cancer
including slowing the progression of prostate cancer and suppressing the
growth of colon, breast, and lung cancer cells. The good news is that
pomegranate’s remarkable health benefits can now be obtained in the form of
affordable, highly concentrated extracts.
Pomegranates have potent hormonal attributes that have been shown to have estrogenic effects without increasing cancer risk unlike hormone therapy. This may be beneficial in safely minimizing menopause symptoms. At the same time they have also been been proven to cause metastatic breast cancer cells to self-destruct.
Mechanism of Action
for Protection from Atherosclerosis
Pomegranate
protects arteries by increasing nitric oxide, which improves the function of
endothelial cells that line the walls of arteries. Nitric oxide (NO) causes
relaxation of the muscles in the walls of the arteries which increases
increasing blood flow. Nitric oxide also reduces injury to the arteries which
helps prevent the development of atherosclerosis.
Research
has shown that oxidized low-density lipoprotein (LDL) can reduce NO levels. Pomegranate juice enhances the nitric oxide synthase activity which
boosts NO. In addition, pomegranate antioxidants prolong the
action of nitric oxide which increases its effectiveness.
Amazingly
Pomegranate has been shown to reverse atherosclerotic lesions in arteries!
An Israeli study showed that pomegranate can actually
reduce existing plaque formations in the arteries. In the study patients with significant
carotid artery narrowing that ranged from 70 – 90% consumed 1.7 ounces of
pomegranate juice each day while others received a placebo. Diet was not changed
Those who drank the pomegranate juice had significant
reductions in the thickness of their carotid artery walls, which is
correlated with decreased risk for heart attack and stroke. After only three
months, the average thickness declined by 13%, and after 12 months, the
thickness dropped 35%! During this same 12-month period,
the average carotid artery thickness of the placebo group increased by 9%.
The
researchers noted a number of improvements in blood markers that help to
explain why pomegranate so effectively supports cardiovascular health. For example, total antioxidant status in
the blood was increased by 130% after 12 months of pomegranate use, while
serum lipid peroxidation was reduced by 59%.
There was also an 83% increase
in serum paraoxonase-1, an enzyme that can reduce harmful lipid peroxides in
arterial cells and in lipoproteins in coronary and carotid lesions. In
addition, one year of pomegranate use more than doubled the time it took for
the initiation of LDL oxidation, from 30 minutes to 65 minutes. Since LDL must
be oxidized before it can stick to artery walls, this delay in LDL oxidation
helps keep plaque from building up. At the same time paraoxonase-1 may help
break up existing plaque, leading to overall reductions in plaque formation
over time.
How to Obtain the
Benefits of Pomegranate
If
you enjoy Pomegranate Juice drinking 8 – 12 ounces each day of a high-quality
product should confer all the benefits seen in research. Of course eating Pomegranates is another great way to get the benefits!
You
can also obtain all these benefits WITHOUT all the sugar contained in juice
by taking a standardized Pomegranate Supplement. Look for products that are standardized
for Punicalagins not just Ellagic Acid.
Ellagic Acid is a highly beneficial chemical, but it does not survive
the digestive tract intact while consuming Punicalagins will result increased
levels of Ellagic Acid after digestion.
Excellent products and brands include:
Jarrow
Pomegranate Extract
Life
Extension Pomegranate Extract
POM

How Much Exercise is Enough?
If a little exercise is good than more is better right? Not so fast. Like most things in life there does appear
to be a sweet spot when it comes to exercise. To understand this, it is important to
keep in mind that the human body is all about homeostasis. Homeostasis refers to the ability of the
body to maintain a balance within its internal environment while being faced
with constant changes in the external environment.
For example, the body tightly regulates many factors such a
temperature. Regardless of outside
temperature the body will adjust heat production to maintain a body temperature
of about 98.6 degrees. There are many
other examples including blood sugar regulation, ph regulation, AND caloric
expenditure!
For example, during conditions of low food intake the body
will slow down the metabolism to maintain caloric equilibrium in terms of the
energy the body is using and taking in. This ability is known at metabolic adaptation and allows us to survive
during famine.
At the same time the body also adjusts to energy production
demands to try to maintain balance between calories in and calories out. Research has shown that there is an
activity/exercise threshold, and when we go above this threshold of exercise
the body adjusts by minimizing movement and slowing metabolic rate when NOT
exercising.
A great example can be seen in elite level swimmers who
spend up to 7 hours per day in vigorous exercise. Anyone who has spent a few days with these
folks will notice that when they are not exercising they are sitting or lying
down and tend to sleep a lot between workouts.
This explains why several very well-designed research
studies show that total daily energy expenditure is NOT always higher in groups
who exercise a lot! At the low range
of physical activity/exercise more activity and exercise IS associated with
higher total daily calorie burn, but for people in the upper range of physical
activity and exercise total daily calorie burn plateaued. Body fat levels and activity levels modulate
metabolic rate aka totally daily calorie burn.
This fits the metabolic adaptation theory perfectly! More fat and less overall movement and the
body will allow you to “waste” more calories in movement. However as fat mass becomes very low
and/or activity levels become very high the body becomes stingier in allowing
energy output so makes adjustments to prevent total daily energy usage from
going higher!
Other studies have shown that maximum health and longevity
benefits appear to max out at about 500 calories per day in formal exercise
activity. This is not to say more is
bad, but rather points out that with exercise there is clearly a point of diminishing
returns.
So more is NOT always better when it comes to exercise!

Kaatsu aka Blood Flow Restriction Training
Kaatsu
training was developed in Japan five decades ago. Ka means
"additional" and atsu means "pressure." An English layman's
term for the practice is "blood flow restriction training," and
involves performing strength training exercises while restricting blood flow to
the extremity being worked.
A
significant benefit of the method is that you can use just 30 to 50 percent of
the weight you'd normally use while still reaping maximum benefits of
resistance training. You use less weight but do more — up to 20 or 30
repetitions versus 8 or 12 in most traditional strength training programs.
Cuffs
or bands are used that are just tight enough to allow arterial blood flow but
not venous flow. This causes lactic acid and other waste products to build up,
giving you the same benefit as heavy lifting without the dangers associated
with heavy weights. For this reason, it's a great strategy for the elderly and
those who are recuperating from an injury.
Scientists
believe that restricting venous blood return can dramatically boost growth
hormone secretion, reducing myostatin and inducing cell swelling. Even better there is less overall tissue
damage compared to traditional high intensity resistance training.
History
of Blood Flow Restriction Training
The
history of this type of training was detailed in an Outdoors Online Article (https://www.outsideonline.com/2023016/you-should-probably-try-japanese-blood-flow-routine
):
"Kaatsu
came about in 1966 when 18-year-old [Dr.] Yoshiaki Sato, now a doctor, noticed
the intense ache in his calves after having assumed the traditional Japanese
sitting position during a typically long Buddhist ceremony. It was an ache much
like the one he experienced after lifting weights — an ache he realized had to
do [with] the occultation of blood circulation.
Eureka!
Using himself as a test subject, Sato spent the next several years perfecting a
system of blood-flow moderation using bicycle tubes, ropes and straps. He later
replaced the tubes with thin computer-controlled pneumatic bands. The idea was
to apply pressure around the arms and legs while lifting a light load, safely
impeding the flow of blood to exercising muscles.
Slowing
this flow engorges the limbs with blood, expanding capillaries, engaging muscle
fibers and raising lactic acid concentration. But — and here's part of what
makes Kaatsu unique — it fools the brain into thinking it's being put through a
vigorous workout."
Kaatsu
training can stimulate muscle growth and strength in about half the time, using
about one-third of the weight, compared to regular resistance training.
How
does Kaatsu Work?
The
concept idea behind blood flow restriction training is to restrict blood flow
in an exercising muscle/s using a band around the upper portion of the arm or
leg being worked. This creates a metabolic disturbance that has local and
systemic effects:
1.
A reduction in the partial pressure of oxygen and increase in the acidity of
the muscle tissue stimulates protein synthesis through an adaptive response to
the stressor.
2.
The central nervous system also senses the challenge and compensates by
increasing sympathetic tone, heart rate, ventilation and sweating. There is also an accentuated hormonal
response as mentioned previously.
Kaatsu
also stimulates mTOR signaling and lowers myostatin (myostation stops muscle
growth!)
Unexpectedly
muscle growth occurs both sides of the cuff even though blood flow is only
restricted on the side farthest away from the heart. The systemic increase in Growth Hormone
also drives overall muscle growth.
How
much Pressure?
It
is important not to restrict blood flow too much, as this could lead to injury
and fainting.
The good news is that research shows
that if you use common sense the risk of using too much pressure is easy to
minimize. Your limb should not be
tingling, turning red, blue or purple, and you should not lose feeling and
should be able to feel your pulse in the limb.
For a great quick start guide to
Kaatsu click here: https://www.kaatsu-global.com/quick-start-guide-001/
Kaatsu
Training Protocol
A
typical training session uses three sets 0f 20 – 30 repetitions per set. use
half or less of the weight you'd normally use. Rest between sets is short with
typical rest time being 30 seconds.
Could
Kaatsu Cause Injury such as Deep Vein Thrombosis?
Kaatsu
is NOT the same as putting a tourniquet on and if you follow proper precautions
is quite safe. The key is that Kaatsu
does NOT alter arterial blood flow as described previously. It is important to use cuff’s designed
specifically for this process.
Contraindications
for Kaatsu
- Women who have had a mastectomy with or without
radiation and/or an axillary node dissection should not use blood flow
restriction training.
- People in hemodialysis who have arterial venous
fistulas. Avoid doing blood flow restriction on the affected limb
- Pregnant women should not use Kaatsu training.

The Role of B-Vitamins in Preventing Brain Loss
One in five people older than 70 suffers from cognitive
impairment which will progress to dementia and death in half of these people
within five years. So it is very
important to address all the modifiable risk factors for cognitive
impairment. One of these risk factors
is elevated homocysteine which is a strong, independent risk factor for
Dementia, Alzheimer’s Disease, and Heart Disease.
One of the longest and most comprehensive studies ever done
showed that one in six cases of Alzheimer’s Disease can be caused by increased
homocysteine levels.
In order to process homocysteine properly the body needs
adequate levels of Folic Acid (Vitamin B-9), vitamin B12, and Vitamin B6. A double-blind randomized controlled trial
showed that the reduction of
homocysteine by B Vitamins can slow the rate of accelerated brain atrophy in
people with mild cognitive impairment which is often the first step towards
Alzheimer’s Disease.
Another study showed that B-Vitamins can reduce brain loss
in areas prone to the Alzheimer’s Disease process.
Other Benefits of
B-Vitamins
B-Vitamins as a group are incredible important to a wide
range of cellular and metabolic functions from energy production to production
of hormones. Benefits of optimal levels include increased energy, improved
mood, reduction of allergy symptoms, help preserve vision, help to maintain bone
strength, and help prevent heart disease and stroke.
How do I get B-Vitamins?
Although it is possible to get the RDA of B-Vitamins through
diet alone it requires a carefully planned diet and for vegetarians it is very challenging because there is no vitamin B-12 in vegetables. Milk, yogurt and cheese, along with eggs,
are the only vegetarian food items that naturally contain significant levels of
vitamin B12.
In addition many people have conditions which prevent
optimal absorption and cellular uptake of certain B-Vitamins such as Folic
Acid. Each of the key B-Vitamins
come in several forms with some being much more active and effective than
others. When everything works right
the body can convert other forms to the active forms, but there are many things
that interfere with this process.
For example Intrinsic factor produced in the stomach is what
allows the intestines to absorb this vitamin.
Not everyone produces intrinsic factor so common sources of B-12 are not
effective.
Also since B-Vitamins are water-soluble excess amounts are
easily and safely excreted so taking a high quality B-Vitamin Supplement or
Multiple Vitamin with activated forms of B-Vitamins in adequate amounts is the
safest way to cover yourself. In
addition, although each B-Vitamin performs critical functions in isolation they
also work together to optimize many functions so taking a complete B-Vitamin
Supplement is highly recommended.
What are all the
B-Vitamins?
B- Vitamin Active Form Inactive Form
B-1 Benfotiamine Thiamine
B-2 Riboflavin-5-phophate
Flavin Monocleotide
B-3 Niacinamide NAD
B-5 Panthothenic
Acid None
B-6 Pyridoxal-5-phospate Pyridoxine
Hydrochloride
B-7 Biotin None
B-9 Methyltetrahydrofolate aka Metafolin Folic
Acid
B-12 MethylCobalamin Cobalamin
Can you take too much
of the B-Vitamins?
For certain ones the answer is yes! You should not take in more than 800mcg of folic acid
supplement. Too much can mask a
condition called pernicious anemia. Multiple Vitamins and B-Complex Supplements will contain 400 – 800mcg
and more from diet is not a problem.
For vitamin B-6 intake above 200mg per day is not
recommended. Again multiple vitamins
and B-Complex will generally contain less than this amount and more from food
is not an issue.
Regular “Niacin” can cause significant skin flushing and
itching, but this is harmless although it can be very uncomfortable. Extremely high dose niacin can be used to
treat high cholesterol levels but the regular form that causes flushing can
also cause liver issues at high levels.
This is also true of “time-released” forms. The best form for use for cholesterol is
“Flush Free Niacin” aka Inositol Hexiniacinate as it will not cause these
issues. NAD (Nicotinomide Adenine Nucleotide) is very safe but there is
no reason to take more than 10mg per day.
As always do not take any supplement when pregnant without
consulting your registered health care professional.

Foam Rolling aka Self Myo-Fascial Release
Using a tubular foam roller to literally roll over tight
areas of muscles and tendons is known as “Myo-Fascial Release”. While it seems counter-intuitive
applying steady pressure to muscles and tendons with an emphasis on trigger
points (areas of tightness and soreness) has been proven to be a highly
effective method for improving mobility.
Since you are in complete control of the amount of pressure
applied and how long it is applied you can customize the experience based on
your level of sensitivity. Key
areas to focus on include the hamstrings, calves, gluteal muscles, latissimus
dorsi muscle, and even low back and hip flexors if done with caution.
You can use a tubular foam roller, and they are made in
varying levels of firmness from soft to very firm. In addition, there are variations that
include a textured surface of varying levels from small to large finger like
projections. You can also use balls
such as a lacrosse ball, baseball, or tennis ball in a similar fashion. NOTE:
the smaller and firmer the object the more pressure it will tend to
apply so proceed cautiously.
The technique is to position the foam roller on the floor (on a
firm but not hard surface is best). Then
position the muscle/s you are targeting on top of the foam roller. For example, for the calf sit on the floor
with your target leg extended so that it is on top of the foam roller with the
lowest portion of the calf on top of the roller.
Use your hands to lift your butt slightly
off the floor to allow you to apply pressure down onto the foam roller. Then literally roll forward slowly over the
foam roller paying attention to any trigger points where you notice sensitivity
or tightness.
When you find a sensitive area slowly roll back and forth on the spot
until you feel it release. With a
little experimentation you will learn how much pressure and speed work best for
your physiology.
Self Myo-Fascial Release/Foam Rolling is a great way to
start a workout and does a great job of safely improving mobility before a
workout and is also great to do between workouts.
Contraindications to
Foam Rolling
Pregnancy – during pregnancy ligaments become lax and
pressure anywhere on or near the abdomen is to be avoided at all costs so best
to skip foam rolling when pregnant.
Osteoporosis – soft bones and additional pressure are not a
good combination so best to avoid foam rolling without a physician’s permission
if you have moderate to severe osteoporosis.
Intervertebral Disc Issues – anyone with disc problems in
their spine should be cautious with foam rolling because pressure in the wrong
areas can create problems so again get guidance from a medical professional if
you have an disc issues in your spine.
Inability to support bodyweight on arms or legs – foam
rolling cannot be done safely if a person lacks the strength to support their
bodyweight on their arms and/or legs.

Energy Drinks Pros and Cons
Energy drinks have become a staple for many people, and
there is lot of controversy about whether or not they are safe to drink. Like most things the devil is in the
details when it comes to energy drinks.
Sugar Content
One of the first points to consider for energy drinks is
their sugar content. Sugar is something
the vast majority of people could do with consuming less not more. People who drink energy drinks with high
levels of sugar are taking in a lot of extra calories - up to 200 calories for
large energy drinks with sugar. This
not only contributes to weight gain and slows or prevents weight loss – it can
also wreak havoc on the millions of people with outright diabetes and the many
millions who are on their way to diabetes due to insulin insensitivity from too
much sugar intake and not enough exercise.
Artificial Sweeteners
Although sugar/carb free energy drinks do not have the
issues associated with sugar described above – artificial sweeteners are
clearly not healthy. Now like all
things it is all about the dosage consumed on a regular basis so someone having
a single beverage with artificial sweeteners daily is very different than
someone having four!
Caffeine Content
Another important consideration is the “energy” ingredients
contained in the drink. The most
common ingredient is caffeine and the typical energy drink contains about 200mg
of caffeine or the same amount you get in a large coffee. If you are an adult and accustomed to
caffeine this will provide an energy bump but will not send you into
convulsions!
However, it is all about
your size and your experience with caffeine.
The more you take in caffeine the more accustomed you become to it, and
larger individuals can safely consume higher quantities for obvious
reasons. Moderate caffeine intake -
300 to 400 milligrams of caffeine per day -- carries "little evidence of
health risks and some evidence of health benefits," conclude researchers
from the Linus Pauling Institute at Oregon State University in Corvalis,
writing in Critical Reviews in Food Science and Nutrition in March
2006. This equates to 2 average size energy
drinks per day.
Other Stimulants
Yohimbine is another potent stimulant so adding
this together with caffeine can cause big problems – particularly in those with
existing high blood pressure.
N-methyltyramine, Octopamine, and synephrine are other
stimulants. As with Yohimbine best to
steer clear of any energy drinks containing any of these ingredients!
Amino Acids
Most energy drinks include amino acids
like L-Phenylalanine and/or L-Tyrosine.
These amino acids act as precursors used by the body to produce
excitatory neurotransmitters and hormones.
So they can amplify the effects of caffeine. NOTE: for people with Phenylketonuria (commonly
known as PKU) phenylalanine can be dangerous but there is a mandatory warning
on all energy drinks containing this substance.
Another common energy drink ingredient is the amino acid
taurine. Taurine is found in large
amounts in the brain, retina, heart, and blood cells called platelets. The best
food sources are meat and fish. Excess taurine is excreted by the
kidneys. Taurine promotes cardiovascular
health, insulin sensitivity, electrolyte balance, hearing function, and immune
modulation. Authors of a 2012 study
actual made the following statement concerning Taurine: “Considering its
broad distribution, its many cytoprotective attributes, and its functional significance in cell development,
nutrition, and survival, taurine is undoubtedly one of the most essential
substances in the body.” So Taurine is
not toxic either.
Another popular ingredient is Glucuronolactone which is
added to “aid in detoxification”.
Interestingly enough there actually is some science supporting this
claim. More importantly it does NOT
seem to be toxic in moderate doses used in most energy drinks. Like the amino acids mentioned above
glucuronolactone is produced in the body naturally so it is not foreign to
cells. There is an urban legend that
this ingredient causes brain tumors but this is just that – a legend!
B-Vitamins
Most energy drinks contain the following B-Vitamins in
significant doses:
Niacin – Niacinamide
B-2 - Riboflavin
B-6 – Pyridoxine Hydrochloride
B-12 - Cyanocobalamin
B-5 - Pantothenic Acid
B-Vitamins are water-soluble meaning excess will simply be
excreted in the urine, and not having enough B-Vitamins can cause serious
issues because B-Vitamins are essential for energy production and many other
functions in the body.
So Why All the
Concern?
Like all stimulants – energy drinks can be abused with
potentially serious consequences.
Heavy intake (3 or more per day) can cause nervousness and anxiety and
heart palpitations. For those with
anxiety disorders, heart disease, or high blood pressure this is a real concern. Anyone with a heart arrhythmia should check
with their physician before taking any type of stimulant including caffeine and
energy drinks.
Certain energy drinks like “Redline” which contain multiple
stimulants have very specific directions to only consume half a small bottle
with a warning that should scare most people. It is very easy to forget and consume a
whole bottle and put yourself in a very uncomfortable and potentially life-threatening
situation.
Always look at serving size, dosage and ingredients and
start with smaller intake. Gradually
increase intake.
Last but not least stimulants can ruin your sleep – so be
very careful not to take them past Noon.
Also if you start to develop sleep issues cut back your intake of all
stimulants – this almost always helps!
Remember stimulants are not a substitute for rest, sleep, healthy diet,
and exercise!

How to Get Rid of Cellulite
Although
the vast majority of woman have some cellulite somewhere on their body – nobody
likes it! So what the heck is cellulite
anyway? Cellulite is pockets of fat that have squeezed between
bands of tissue, called septae, that are located below your skin.
Women of all races get it, while virtually no men do.
That's because the septae of men are different from women. Men have stronger
bands that are cross-hatched allowing them to keep fat in place more
effectively. Women have weaker, vertically oriented septae that allows fat to
squeeze through easier.
Both thin and heavy women have cellulite. However the
higher your level of body fat the more noticeable the dimpling will tend to be. Unfortunately dieting does necessarily help eliminate
cellulite. Losing weight helps sometime, but in some cases weight loss makes
cellulite worse. This occurs when skin
becomes saggy after significant weight loss.
There is a definite genetic component to cellulite
which does run in families.
Hormones also are part of the equation with cellulite,
but science has not figured out exactly how hormones contribute to
cellulite. What is known is that
cellulite starts at puberty which is a time that many hormone levels change
significantly in females.
Getting
Rid of Cellulite
Getting rid of cellulite is easier said than
done. Even treatments like Liposuction
are not necessarily effective. In fact
Liposuction often makes cellulite worse by leaving your skin even more puckered
looking than it was before.
Dermatologists are quick to point out that there is no
magic cure for cellulite, but there are ways to make it look better! Two of the keys are working out and dropping
excess weight sensibly (1lbs per week! – faster weight loss can exacerbate the problem!)
Resistance training is key. As you increase your muscle size and
decrease body fat your skin looks smoother.
If you lose fat while you simultaneously build muscle your cellulite
will improve.
It is also important to work on the health of your
skin as you age to make it more elastic so that as you lose fat the skin pulls
tight rather than sagging.
Certain
topical treatments that increase collagen in the skin, like Retin-A or creams
with retinol or vitamin C, cannot hurt and may help.
Maintaining adequate water intake is also
key for skin health and elasticity – 6 – 8 glasses of water per day is key.
If you have faithfully tried everything and your
cellulite is driving you crazy and you are prepared to spend some serious
dollars – Cellulaze – is an FDA approved therapy. Cellulaze involves inserting a lazer under the skin
and projects heats in three directions and literally liquefies fat as it cuts
the septae around fat cells which can reduce the puckering while also
encouraging collagen regrowth.
Cellulaze claims a 70 – 80% improvement in cellulite
that lasts a full year. It is most
effective for active women with mild to moderate cellulite who are not
significantly overweight and who also have good muscle tone.
Unfortunately, Cellulaze is not cheap – costing $5,000
- $7,000 depending on the size of the area being treated.

How Much Protein Do You Need Each Day?
One of the most controversial and confusing aspects of
nutrition is how much protein people should consume each day. There are several factors to take into
account to get a good answer to this question, and there are potential problems
with eating too much protein. There are
also definitely problems with not eating enough protein. It is also important to consider what type of
protein is being consumed.
Height, weight, age, sex and activity level all factor into
your protein needs. Obviously the
larger you are the more protein you need to take in to support structural proteins
throughout the tissues of the body including the muscles, bone, skin and
organs. In the same way the more active
you are the more protein you need to consume. In addition, protein is used to create
enzymes, and enzymes are critically important for all cellular function.
Protein is made up of amino acids and there are essential
and non-essential amino acids.
Essential amino acids MUST be consumed because they cannot be made by
the body. Complete proteins contain
all the amino acids and come from meats, poultry, fish, eggs and dairy. While vegetarian proteins are not complete
it is not hard to combine different plant protein sources to obtain all the
protein the body needs to function.
Other factors which influence how much protein is required
is overall caloric/energy status. If
you are eating enough calories to maintain bodyweight or gain bodyweight you
require less protein as a percentage of overall calorie intake while those
people in caloric deficit require a higher percentage of their overall calorie
intake to maintain lean tissue mass (losing lean mass like muscle is usually
NOT a good idea so this is important).
How much is too much?
In large amounts and for certain populations (such as those
with compromised Kidney Function) excess protein can cause problems. That being said, for the normal healthy individual,
the body can easily and safely process and use a lot of protein. A portion of the protein you eat is
frequently converted to glucose (blood sugar) and if your overall calorie
intake is too high you will convert excess protein into fat like ALL unused
excess calories.
Another potential problem with too much protein is that high
protein intake stimulates the release of mTOR which stands for Mammalian Target
of Rapamycin. mTOR is a key regulatory protein that
signals for cell growth through the creation of new proteins. Consider protein
building similar to a race car. The larger the engine, the greater potential
for speed. Similarly, the more mTOR present in any given cell, the greater
potential for more protein construction. And just like the gas pedal fuels the
engine, mTOR is a signaling protein, and can be various levels of active (like
a pedal’s ability to regulate speed). If a number of different processes all
signal for ‘Go’, then the cell builds as much protein as it can, as quickly as
it can. So just as a souped-up car takes off rapidly, a muscle cell can signal
for tremendous muscle growth very quickly, given the right conditions. n
For this reason, mTOR is a good thing when you are looking for muscle-building! However, there is a potential dark-side to mTOR. Cancerous tumors are designed to grow as fast as possible, and they rely on mTOR signaling to build proteins just like healthy cells. So too much mTOR could theoretically put people at a higher risk of developing rapid and serious cancers. In fact, a lot of cancer research is based around slowing down and minimizing mTOR activity in tumor cells (the exact opposite goal of muscle research).
This doesn’t necessarily mean that eating more protein for
muscle building is going to cause cancer. Numerous other proteins and factors
come into play, and some may respond differently in muscle cells than in
cancerous cells.
Safe and Adequate Protein Intake
The Institute of Medicine's protein RDAs are calculated using 0.8
grams of protein per kilogram of body weight. This means an adult who weighs 68
kilograms needs at least 54 grams of protein each day. The RDA for
pregnant and nursing women is 71 grams of protein per day. Keep in mind the RDA is a MINIMUM and does
not mean this is ideal! This also
assumes you are sedentary! So, if you
are exercising and trying to build muscle or older and trying to prevent muscle
loss higher protein intake is better. To
determine your minimum daily intake, divide your body weight by 2.2 to
determine your weight in Kilograms and then multiply by .8 to get your minimum
daily protein intake.
The Academy of Nutrition and Dietetics states that although athletes only need about 1 gram of protein per kilogram of bodyweight to maintain muscle mass, they require 1.4 to 1.8 grams of protein per
kilogram to build muscle mass; this is equivalent to about 0.64 to 0.82 grams
of protein per pound of body weight each day.

Workout Anytime Daily 10 Prehab Routine
Everyone knows that prevention is better than dealing with
an injury, and part of injury prevention is spending time working on what are
commonly referred to as “corrective exercises” or “Prehab”. 10 minutes a day spent doing 10 basic
exercises can prevent many injuries, improve results from exercise, and
dramatically improve movement.
Ideally do these exercises barefoot or in socks – your feet
will be working very hard during these exercises and shoes reduce ground
feel. If possible do them in front of
a mirror to see your form!
Hip Hinge – Hip
Hinging is one of basic primal movement patterns, and it is also the movement
pattern most frequently done incorrectly. The best way to groove this movement pattern is practice it using a
wooden handle or PVC Pipe held vertically against your back touching the back
of your head, the top of your shoulders, and your tail bone. By keeping contact with all three points
as you hinge it teaches you to maintain a flat back which is essential for
preventing low back injuries and developing proper movement mechanics that
allow you to effectively load and unload the glutes and hamstrings.
It is also a phenomenal dynamic warm-up for the hamstrings! Here is a video showing how to do it: https://www.youtube.com/watch?v=PG67O49Hsso Do 50 reps per day and you will see and
feel positive changes in your posture, movement, strength and mobility!
Downhill Skier Exercise
– This exercise contains elements of the squat and hip hinge. Start by placing the hands palm down on the
top of the thighs. Keep the back
straight slide the hands down until the palms are resting on the knees with the
hips back like you are a second basemen. You should begin to feel a stretch in the hamstrings. Continue to hinge from the hip forward and
slide down until your elbow are resting on the inside of the knees with back
straight and hips back like you are a downhill skier. This will require your knees to track
forward over and maybe even slightly beyond your toes (this will generate a
stretch in the calf muscles and specifically the single joint soleus
muscle). Keep your heels down the
whole time – do not let them lift up off the floor!
Keeping the back totally straight extend the knees as far as
possible – you should feel a strong stretch in the hamstrings. Your hips will rise but keep your elbows on
the knees and do not move the upper body!
Then drop the hips, flex the knees and let them move forward over toes
as you drop back down to the downhill skier posture.
Start slow but as you get the hang of it you can move faster
– as long as you maintain proper form.
Do 30 – 50 reps every day. You
will start to notice that your squat and your hip hinge movements all get
easier along with improved mobility in the ankle knee and hip! Click here for a great video of how to do
this exercise properly: https://youtu.be/nXKWtlr3rBQ
Goblet Squat –
Squats are another primal movement pattern and goblet squats help emphasize the
best form. They should be done daily
with a relatively light weight for a good 20 – 50 repetitions. Keep the dumbbell, kettlebell or Sandbag
held against the chest the entire time. If you have difficulty getting thighs parallel to the floor spread your
feet farther apart, and also rotate out at the hips so that your feet are
pointing outwards. This can make a
huge difference. By doing this and
holding a light weight against your chest you may find you can squat to a
decent depth while maintaining an upright torso. It should look like this: http://cfitness.me.formecdn.com/2016/12/goblet-squat.jpg
Alternatively you can hold a kettlebell/Dumbbell
with both hands letting it go straight down between the legs as you squat down
like this: http://workoutlabs.com/wp-content/uploads/watermarked/Pile_Sumo_Dumbbell_Squat1.png
Single Leg RDL –
Romanian Deadlift – is one of the most important corrective exercises you can
do to help self-identify and correct muscle imbalances that are the most common
cause of movement dysfunction and injury.
The best way to do this exercise is barefoot in front of a
mirror where you can see your whole body throughout the entire sequence of the
exercise. Ideally you should be on a
firm and level surface as well.
Start by facing the mirror standing on one foot with the
other leg flexed so your thigh is parallel with the floor and knee flexed to 90
degrees with hands on your hips. Look
in the mirror and make sure your hips are perfectly level and if not fix
that!
Next, without moving the upper body extend the flexed leg
down and hinge forward at the hip of the standing leg. As your swing leg passes the other leg you
should try to straighten it, and ideally you hinge forward at the upper body
while keeping your swing leg and upper body in a straight line the whole time.
As you hinge try NOT to let your swing leg hip drop and keep
your stance foot pointing directly forward with no angle. The stance leg should flex slightly but the
knee should NOT move forward – rather you should “sit” back into the hinge at
the hip. Pause when you reach at or near parallel with the floor with
your upper body and swing leg then smoothly return to standing and flex the
swing leg. Slower is harder AND better
and do NOT use any load/weight.
10 repetitions on each side each day! Do all 10 on each side one time per day and
you will see some amazing changes in your strength, balance and
athleticism!
Here is a great single leg RDL tutorial: https://www.youtube.com/watch?v=vc21IwnIcwk
Hip Thrusts – The
hip thrust simultaneously develops the glutes while enhancing mobility in the
hip flexors (both key because this counteracts the negative effects of sitting
all the time!). These can be done on
the floor or with shoulders on a bench, bed or sofa to make it a bit
harder. You can do hip thrusts with two
legs or one leg at a time to create additional load. Here is a good shot of the exercise: http://cdn-www.womenshealthsa.co.za/wp-content/uploads/2015/02/hip-thrust-hold.jpg
Important NOT to arch lower back at all and concentrate on squeezing glutes at
top and NOT using low back. Even
without any load this exercise can produce great benefits – 20 – 50 reps each
day!
Plank – The plank
is a simple functional core exercise that produces great benefits. It can be done on toes and hands (upper
push-up position), Toes and Elbows, Hands and Knees, etc to adjust the
difficulty. Do a version of the plank that challenges for
one minute per day while maintaining good form. Here is a great article on some of the many
variations: http://www.health.com/health/gallery/0,,20813896,00.html/view-all
Side Plank – The
Side Plank is also key to building core strength, but in the front plane (side
to side stability and strength). 30
seconds to a minute on each side each day.
Like the plank there are many variations and one of the best when you
are ready is a side plank with leg lift: https://rutheburke.files.wordpress.com/2015/05/side_bridge_abd.jpg
Static Lunge –
Lunges are another primal movement pattern, and there are many different
variety of lunges. A static lunge is
done with feet in a split stance like this:

The exercise is fantastic for simultaneously
developing strength and mobility in the foot, ankle, knee and hip. Best done barefoot on a firm surface. Keep your front heel down the entire time and
rear foot is up on ball of the foot with rear knee, hip, back and head kept in
alignment the entire time. Do 10 reps at a time on each side per day –
no weight is necessary.
Side to Side Skater
– This exercise develops hip mobility including providing an excellent dynamic
stretch/warm-up for the adductor (inner thigh muscles). Feet should be wide apart with feet
facing forward – not angled out. Keep feet flat on the floor and flex forward at the hip keeping back
straight (only flex forward as far as you can while maintaining a flat back and
keeping both feet on the floor with entire foot kept down in contact with the
ground). Push the hips directly to
the side and pause as you feel a stretch in the trailing leg’s adductors.
Ideally your head and torso stay
perpendicular to lower body and centered during the entire exercise just like a
speed skater. Then push your hips back
in the other direction to the other to the other side. NOTE:
Do NOT go up and down – your hips should go back and forth in a straight-line
parallel with the floor. Do 20 – 30
reps each day.
Ankle Circles –
This exercise improves ankle mobility and is great before just about any
activity. Stand on one foot. These can be done seated, standing or lying
down – best done standing to simultaneously work on balance and stability. The action is simple: holding foot and leg in the air draw a
circle with your toes for 10 circles in one direction and 10 circles in the
other direction like this: http://web.eccrsd.us/christy/public/athletic_training/ankle_sprain_rehab_beginner_files/Picture%201.jpg
You will notice that one direction is much
harder than the other and you will feel much less coordinated and same thing
with one leg vs the other leg. Do
more repetitions in the direction that is challenging and more on the leg that
is more challenging. Ideally do the
exercise while you stand on one foot while you pull your other leg up with knee
bent so that your thigh is parallel with the floor. This is more challenging than it looks but
will provide big benefits in terms of balance and stability.
Done daily and before workouts these 10 exercises will
provide big benefits including improved posture, stability, strength and
mobility. You will also notice that
you improve at many other exercises and movements.
