What you Should Understand about Green Coffee Bean Extract

Chlorogenic acid is the active ingredient in green coffee bean extract thought to assist in weight loss.
The supplement is amongst the most in-demand weight reduction aids in today’s market.
According to a recent Gallup poll, more than half of Americans say they desire to shed pounds. (1)
No big surprise there, since nearly two thirds of Americans classify as overweight or obese, and carrying
excess weight is considered a leading public health problem in our country. (2)
You may well be one of those contributing to the annual outlay of $60 billion on weight loss products
(3), which includes gym memberships, fitness equipment, supplements, and specialty foods.
We all want to get something for the money we spend, particularly when it comes to fat loss aids that
claim to aid drop numbers on the scale.
Let’s see if green coffee bean extract merits a slot in your budget.
The Magic Ingredient: Beyond Caffeine
Human studies confirm caffeine boosts metabolism, causing the body to burn more calories, so that’s a
good starting point if you enjoy coffee. (4)
Incorporating green coffee bean extract in your diet program could boost the effectiveness of caffeine
while adding other health benefits.
When coffee beans are roasted, the chlorogenic acid is lost (5, 6), whereas raw, green coffee beans are
rich in the stuff.

Chlorogenic acid takes coffee’s effect on metabolism to a new level by inhibiting the absorption of
carbohydrates in the digestive system. This mutes the body’s insulin response, which results in keeping
blood sugar levels lower. (7)
Here’s how mice and rats responded to chlorogenic acid in lab tests: (8, 9)
• Body weight reduction
• Less absorption of dietary fat
• Less fat trapped in the liver
• Raised levels of adiponectin, the fat-burning hormone
• Reduced absorption of glucose
There’s no guarantee the substance has the same impact on humans, but other health benefits noted in
animal studies included lower triglyceride and cholesterol levels (10), both of which are risk factors in
developing cardiovascular disease.
Weight Reduction Studies
A small randomized, controlled trial dealing with 30 overweight participants during a 12-week period
showed promising results for supplements containing green coffee bean extract. (11)
One group drank coffee with 200 mg of green coffee bean extract added, while the other group drank
regular coffee. Nobody was asked to make any modifications in diet or exercise.
Those taking the extract dropped nearly 12 pounds, while the control group was down 3.7 pounds over
the three months.

The control group experienced a reduction in body fat percentage of under 1%, while the others
measured a substantial change at 3.6%.
An extended study of 22 weeks involved 16 overweight participants. In this group, two separate dosage
levels of green coffee bean extract (1050 mg and 700 mg) were used, along with placebos. Subjects took
a two-week break between changing dosage or, in some cases, taking a placebo. (12)
The largest amounts of weight reduction occurred during the time periods when participants were
taking green coffee bean extract.
Average reduction was just over 8 pounds, and body mass index measurements dropped enough to shift
some participants from pre-obesity to normal ranges. Decreases in body fat averaged near 5%.
Other studies have been conducted by companies who profit from the sales of green coffee bean
extract, a common practice that should inspire caution when reviewing the outcomes since the
methodology isn’t as rigorous or standardized. (13, 14)
Other Considerations
While longer studies with more participants will assess if green coffee bean extract can be a significant
boon to anyone seeking to drop unwanted weight, chlorogenic acid may be in the running for improving
health in other ways.
The substance possesses strong antioxidant properties, and may have positive effects on blood vessel
health. (15)
Subjects using 140 to 720 mgs of green coffee bean extract in one study had lower blood pressure
measurements, a significant marker for heart health. (16, 17)
The muting effect of the chlorogenic acid on glucose absorption could be helpful in managing symptoms
of diabetes.

While the safety profile of green coffee bean extract is generally good, respiratory reactions may occur
in people with allergies (18). If you know you’re sensitive to coffee, consider skipping the risk of using
the extract.
When caffeine is consumed in considerable amounts, it can cause side effects like rapid heartbeat,
nervousness, insomnia and anxiety. Pregnant women and children shouldn’t use caffeine, including
green coffee bean extract. (19)
Chlorogenic acid can exert a laxative effect in certain individuals, causing diarrhea. Dosages of
chlorogenic acid usually run between 120 and 300 mg, which results in somewhere between 240 and
3000 mg of green coffee bean extract.
Should You Try Green Coffee Bean Extract?
The concept that weight loss success can be achieved with a supplement like green coffee bean extract
is appealing, especially for those who haven’t reached their goals through dieting alone.
Since one of the strengths of chlorogenic acid is to reduce the effect of carbohydrates on blood sugar,
many people might see this as a way to support weight reduction efforts while still being able to eat
refined carbohydrates and other foods loaded with sugar content, all of which spike insulin levels and
contribute to fat storage.
While it’s true these are “fun” foods to consume, controlling the damages inflicted by ingesting them
isn’t the most effective approach.
Making modifications in lifestyle is the only proven method for maintaining normal weight and
improving overall health. For most of us, this means cutting back or eliminating the foods that cause
blood sugar problems and weight gain, replacing them with whole, nutritious choices, along with
engaging in regular exercise.

If you decide to give green coffee bean extract a go, a great choice of capsules in various strengths can
be obtained; like many supplements, the cost will often run around a dollar a day for recommended
dosages.
Instructions usually say to take one serving about half an hour before each of three meals daily. Use
caution and begin with a single dose daily if you’re the sensitive sort.
