Ripped Fuel Reviews
The combination
of ephedrine, caffeine and aspirin is a widely documented nutritional
method of inducing weight loss. Numerous studies have confirmed
the effectiveness of the ingredients in Ripped
Fuel Extreme. For more discussion on what results you can
expect when taking Ripped Fuel, see Ripped
Fuel Results.
Like any fat
burner, Ripped Fuel is only as good as its ingredients. So Ripped
Fuel reviews includes a complete analysis of each of its fat-burning
ingredients.

Ingredients In Ripped Fuel
Ephedrine
and Caffeine
Renowned weight-loss expert Arne Astrup, MD, and his associates
performed a study with ephedrine at the University of Copenhagen
and two Danish hospitals. Five young females were given 20 mg
of ephedrine three times per day one hour before meals and were
told to continue eating normally. Even though there was no dieting
involved, the women lost an average of 2.5 kg of body weight after
four weeks and 5.5 kg after 12 weeks. They also held onto their
lean muscle, while their body-fat percentage dropped by 3.5% after
four weeks and 5.2% after 12 weeks. Two months after the experiment
stopped, they had only gained back 0.5 kg. The only side effect
was a mild rise in blood pressure at the start of the experiment.
Two studies by the same Danish researchers indicate the benefits
of combining ephedrine with caffeine. In both studies, the participants
took a supplement with 20 mg of ephedrine and 200 mg of caffeine
three times per day. They also followed a low-calorie diet. In
the first study, the test subjects lost 16.2% of their body weight
in 24 weeks, significantly more than the 13.4% loss by the placebo
group. The second study confirmed that most of this loss was body
fat. In that eight-week study, the E/C group lost 10.1 kg, compared
to only 8.4 kg with the placebo. But the E/C group lost twice
as much fat (9.0 kg vs. 4.5 kg) and much less fat-free mass (1.1
kg vs. 3.9 kg). Only mild side effects were reported.
The E/C combination has been extensively studied, but space limitations
do not allow a detailed listing of the many studies that have
showed benefits. All of this research, however, supports the effectiveness
of the E/C stack and demonstrates the moderate level of side effects
when you take appropriate dosages. (For more information on the
side affects of Ripped Fuel, see Ripped
Fuel Side Affects.)
A study in the American Journal of Clinical Nutrition
found that when green tea was taken instead of pure caffeine,
the thermogenic effects were even stronger. This six-week study
compared the benefits of pure caffeine (50 mg), green tea extract
(with 50 mg of caffeine and 90 mg of EGCG) and placebo. The pills
were given three times per day. The green tea group experienced
a significant 4% increase in thermogenesis and a 4.5% boost in
overall energy expenditure.
Citrus aurantium
A study published in Current Therapeutic Research recently
investigated the weight-loss benefits of a supplement containing
Citrus aurantium, caffeine and St. John's wort. The researchers
divided 23 overweight individuals into three groups. One was given
the Citrus aurantium combination. Another group got a placebo,
while the third group did not receive any supplement. All of the
subjects followed the same exercise and diet routine for six weeks.
By the end of the experiment, the Citrus aurantium group had lost
13% of their fat mass while increasing their basal metabolic rate
by 3%. While the St. John's wort, an herbal antidepressant, may
have reduced appetite to some extent (people tend to eat more
when they are depressed), the researchers felt that the synephrine/caffeine
part of the formulation was the primary reason for the benefits
in fat loss and enhanced metabolism. No published studies have
examined the benefits of Citrus aurantium on its own.
Willow bark extract
Several studies have shown that aspirin contributes to energy
expenditure, particularly in obese individuals. It appears to
do this by raising the body's internal "thermostat,"
so that the increased production of heat produced by E/C products
does not trigger a response by the body. This allows fat burning
to continue longer than it otherwise would. Although no study
has compared the benefits of the E/C stack with and without willow
bark, the effects are probably similar to those of aspirin.
Citrus bioflavonoid complex
Numerous studies have indicated that the citrus bioflavonoid naringin
prolongs the chemical activity of caffeine. Research published
in the British Journal of Clinical Pharmacology found
that the half-life of caffeine was extended by 31% when naringin
was present in sufficient amounts. Studies of various citrus fruits
have shown that grapefruit has by far the highest content of naringin.
It is, in fact, what gives grapefruit its characteristic bitter
taste. The activity of other citrus bioflavonoids has not been
studied.
Cayenne
The capsaicin in cayenne has been shown to be effective in animal
and human experiments. In a recent 14-day study, rats were given
capsaicin or placebo and put on an exercise program. Compared
to the control rats, the capsaicin group had a greater reduction
in their fat stores. These benefits appear to take place with
both high-carb and high-fat diets. A study of Japanese women on
these two types of diets found that adding cayenne to their food
led to increased energy expenditure and fat oxidation. Both of
these effects would result in a loss of body fat over time.
Ginger root
Ginger has a long history of use as a treatment for motion sickness.
In one double-blind, placebo-controlled study by Danish researchers,
naval cadets unaccustomed to sailing in rough seas were given
1 gm of ginger root or placebo every hour for four hours. The
ginger root reduced the tendency toward vomiting and cold sweating.
Thermogenic formulations only produce gastrointestinal distress
in some sensitive individuals, so ginger should definitely be
able to relieve these much milder symptoms. There are no studies
showing that ginger by itself has fat-burning properties.
Coleus forskohlii
An eight-week study with six overweight females found that Coleus
forskohlii can significantly reduce body weight while increasing
lean body mass. The subjects were given 250 mg of an extract standardized
to 10% forskolin twice daily. One capsule was ingested in the
morning and the other in the evening, half an hour before each
meal. Subjects were instructed to maintain their normal activity
levels and dietary practices. After four weeks, there was an average
loss of 4.3 lb of body weight. After eight weeks, the subjects
lost an average of 7.2 lb, and their body fat percentage dropped
from 33.6% to 25.9% as determined by bioelectrical impedance.
No significant side effects were noted, although blood pressure
tended to decrease during the experiment.
