BURN BABY BURN

Choose the perfect fat burners to help you get ripped
Month by month we present diet, training and supplementation programmes for
getting shredded. These form your foundation for getting lean and hard. However,
if you
want to crank things up a notch or if you believe that any bodyfat-reduction
programme requires fat-burning products, here’s our guide to a range of
those supplements. Remember that fat burners aren’t magic; they will
be beneficial only if combined with the proper exercise and nutrition programmes.
BUILD YOUR BURNER Deciding which thermogenic and how much
to take can prove challenging. Many bodybuilders rely on the basics — caffeine or other stimulants. If
one of these options works for you, great, but many bodybuilders steer clear
of stimulants such as caffeine because they can cause jitters. Based on your
experience and knowledge, decide whether you should substitute another thermogenic
(or two or three) for caffeine or other stimulants, or whether you should simply
add to the mix. FLEX gives you the lowdown on several fat-burner ingredients
that are among the best available, and we provide you with two stack options
for burning bodyfat (see “Stack It Up”) to help you make a choice.
Keep in mind that many fat-burning ingredients work through different mechanisms
and can be highly complementary. Synephrine is a good alternative to ephedrine
and its actions can be augmented by caffeine. You can use 7-Keto to enhance your
metabolic rate. Green tea extract is a great choice for an added fat-burning
boost to stimulants such as caffeine or as a fat-loss supplement on its own.
Tyrosine and forskolin also can be excellent components of an effective fat-burning
stack.
Of course, some bodybuilders may want to go wild with these five fat burners
and add them all to their basic thermogenic combo. This is fine, as long as
you have no medical conditions that would preclude taking them and you don’t
mind shelling out the cash. As always, though, FLEX recommends starting slowly,
adding one new supplement at a time so you can get a sense of what works best
for you. Every week or two, add in another to take your fat burning to a higher
level. Whatever you choose, keep dosages within the recommended amounts. This
enables the fat burners to work effectively without encouraging side effects.
SYNEPHRINE This product is an extract from a fruit called bitter orange, also
known by its scientific name Citrus aurantium, and it may be listed on product
labels as zhi shi. Its structure and its actions in the body are similar to ephedrine.
This is why synephrine has popped up on the supplement scene as an ephedrine
alternative.
POSITIVES
• Synephrine has been shown to significantly increase metabolic rate and
fat loss similar to, but somewhat weaker than, ephedrine.
• Its effects are enhanced when caffeine is also used.
•
Synephrine doesn’t raise blood pressure or heart rate to the extent that
ephedrine might.
• Studies have found that most subjects report a feeling of greater energy
for
several hours after ingesting synephrine.
NEGATIVES
• The increase in metabolic rate and fat loss do not appear to be quite
as strong as those reported with ephedrine.
•
It provides a mild and temporary increase in blood pressure — do not
take it if you have a history of cardiovascular problems.
• Do not take it if you are on MAO inhibitors.
VERDICT
Synephrine appears to be a beneficial component of the ultimate fat-burner stack.
DOSAGE
Take 5-25 milligrams (mg) of synephrine (from a standardised Citrus aurantium
extract) once or twice per day for a maximum of 50 mg.
TYROSINE This nutrient is used by the body to make a number
of important hormones, including the thyroid hormones, as well as the one that
ephedrine mimics — norepinephrine (NE). NE is one of the main hormones
in the body that promotes
thermogenesis and the breakdown of bodyfat.
POSITIVES
•
Dietary tyrosine has been shown to increase NE levels, indicating it may help
improve the fat-loss effects of other stimulants such as caffeine. Tyrosine’s
effect on the brain is often overlooked, presumably because some bodybuilders
don’t think of the brain as being key to fat loss. Nevertheless, most
of the fat-loss effect from thermogenics is the result of action on
brain receptors for NE that govern appetite. In fact, boosting levels of NE in
the brain is one of the most widely used methods to control appetite.
• Tyrosine may be used as a substitute for ephedrine. Although its effects
on metabolism and fat loss are not as strong, tyrosine does enhance NE production
in a fashion
similar to ephedrine.
• Tyrosine helps increase the appetite-curbing effects of stimulants such
as caffeine without increasing blood pressure.
• Some bodybuilders experience rebound fatigue when they go off ephedra-related
herbs; tyrosine can help in recovering from that fatigue. This makes sense,
as tyrosine acts by providing raw material from which NE levels can be restored,
a process that is depressed for a short time after ephedrine is withdrawn.
NEGATIVES
•
Elevated levels of NE in the brain can give some people the jitters; some may
notice nausea, unless a “slow and steady” dosing schedule is used.
•
Don’t take tyrosine if you have skin cancer, because it may speed growth
of this type of tumour, and avoid it if you have a mood or bipolar disorder.
VERDICT
Tyrosine is a good choice as a stand-alone supplement or as a complement to other
fat-burning ingredients.
DOSAGE
Take 500 mg to two grams (g) in the morning and 500 mg to 2 g later in the day.
Some find tyrosine stimulating, so avoid it after 3 pm if it keeps you up at
night.
GREEN TEA EXTRACT Green tea contains several polyphenolic compounds called catechins.
These are the antioxidants that are credited as being therapeutic for a host
of ailments, including cancer, heart disease, liver disease and obesity. In fact,
green tea is so popular as a perceived panacea that it is sold in capsule form
at health-food outlets and chemists.
POSITIVES
• Research shows that supplementing with green tea extract over a three-month
period has a fat-loss effect on the body; 270 mg of a compound called EGCG derived
from
green tea increases energy expenditure by about 4% per day, which can mean
more than 150 extra calories burned per day for many bodybuilders.
• Green tea is good for you, encouraging the death of cancerous cells of
the prostate.
• Green tea might also help prevent other cancers, heart disease and joint
problems.
NEGATIVES
• Because EGCG delays blood clotting, avoid taking green tea extract before
surgery or while taking blood-thinning or anti-inflammatory drugs (interaction
is more
likely if you are also taking vitamin E, fish oil or ginkgo biloba).
VERDICT
Green tea extract is a very promising candidate as part of a perfect fat burner.
DOSAGE
We recommend taking green tea extract standardised to 90 mg of EGCG (or 270 mg
of polyphenols) two or three times per day.
FORSKOLIN Coleus forskohlii is an herb containing the active ingredient forskolin
(colforsin), which activates a hormone that breaks down fat stores. Forskolin
has been shown to increase thyroid hormone production as well as to stimulate
thyroid hormone release, thus helping to keep fat-burning operations optimal.
POSITIVES
• Supplementing with forskolin may help you reduce bodyfat. In addition,
it can also be effective when applied topically.
• Forskolin may have a muscle-preserving effect like that of ephedrine
and caffeine, as it ultimately triggers the same biochemical pathway. Taking
a concentrated
extract of forskolin has been shown to help preserve muscle mass, and it may
do the same for bodybuilders who use it as a substitute for ephedrine.
• Unlike ephedrine and caffeine, forskolin causes an overall drop in blood
pressure, which could be good for those with elevated blood pressure or for those
who want
to counter the effects of stimulants.
NEGATIVES
• A slight drop in blood pressure might be welcome for most bodybuilders,
but it is prudent to avoid forskolin if you have a heart condition. If you have
cancer
of the prostate, the supplement can interfere with test results for this condition.
VERDICT
Use forskolin as an ingredient in your fat-burner combo to help boost and balance
the effects of other fat burners.
DOSAGE
Extracts of Coleus forskohlii herb standardised to 18% forskolin are widely available.
Take 20-50 mg two or three times daily. Avoid getting more than 150 mg total
of forskolin per day.
7-KETO Three-acetyl-7-Oxo DHEA (7-Keto) is a natural metabolite of dehydroepiandrosterone
(DHEA), the hormone produced by the adrenal glands to form testosterone. It increases
metabolic rate either directly or through an increase in thyroid hormone.
POSITIVES
• Although technically a prohormone, this DHEA derivative does not have
androgenic properties, which means females do not have to worry about masculinising
effects.
• A recent study in healthy males found the supplement to be safe at dosages
up to 200 mg per day.
• Several studies confirm a positive link between 7-Keto levels and thyroid
hormone levels.
NEGATIVES
• Lack of research on its fat-loss properties in humans makes it difficult
to confirm the fat-burning results of anecdotal reports.
VERDICT
A good supplement to take along with other fat burners.
DOSAGE
Take 100 mg of 7-Keto per day in two or three divided doses.
Deciding to use any type of a fat burner is a personal choice. Fat burners
can be a successful complement to your nutrition and training programme, helping
you to accomplish your physique goals. Nothing is a substitute for hard work
in and out of the gym, but finding the right fat burner can give you the edge
you’re looking for. FLEX
