I was confused, because some places say the study was 12 weeks and some say it was 22. So which is it? Well with some searching I found the original study results, so here it is.

Background:
Adult weight gain and obesity have become worldwide problems. Issues of cost and potential side effects of prescription weight loss drugs have led overweight and obese adults to try nutraceuticals that may aid weight loss. One promising nutraceutical is green coffee extract, which contains high concentrations of chlorogenic acids hat are known to have health benefits and to influence glucose and fat metabolism. A 22-week crossover study was conducted to examine the efficacy and safety of a commercial green coffee extract product GCA™ at reducing weight and body mass in 16 overweight adults.

Methods:
Subjects received high-dose GCA (1050 mg), low-dose GCA (700 mg), or placebo in separate six-week treatment periods followed by two-week washout periods to reduce any influence of preceding treatment. Treatments were counterbalanced between subjects. Primary measurements were body weight, body mass index, and percent body fat. Heart rate and blood pressure were also measured.

Results:
Significant reductions were observed in body weight (-8.04 ± 2.31 kg), body mass index (-2.92 ± 0.85 kg/m2), and percent body fat (-4.44% ± 2.00%), as well as a small decrease in heart rate (-2.56 ± 2.85 beats per minute), but with no significant changes to diet over the course of the study. Importantly, the decreases occurred when subjects were taking GCA. Body mass index for six subjects shifted from preobesity to the normal weight range (<25.00 kg/m2).

Conclusion:
The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss. The results suggest that GCA may be an effective nutraceutical in reducing weight in preobese adults, and may be an inexpensive means of preventing obesity in overweight adults.

I started a thread asking about Green Coffee pills a week ago. This is what I bought : Pure Health Natural Pure Green Coffee Bean pills. 30 pills in a bottle for $10.00. I take 2 30 minutes before I eat and sometimes I just take 2 more when I feel like I need a little extra energy. They are all natural and my doctor says they are completely safe. I also bought Pure Health Raspberry Ketone. 30 pills for $10.00. I take 2 of them at the same time that I take the Coffee pills. I do not feel jittery or any kind of side effect. It just gives me a little extra get up and go. I've heard that they don't work for some people. My mom takes them and she says she can feel the difference from taking them. I can, too. You can take one or the other or both at the same time. It's cheap enough to try if you don't mind taking a pill. I know some people don't like taking pills. That's my update on them. Hope it helps.

I posted a thread on this earlier.

Oh and if I take them to close to bedtime I can not go to sleep for anything. And they are 400 mg for each pill. A serving is 2 pills though.

I know this is off topic and gross but... did anyone experience pale poops after taking green coffee extract? I have taken for 3 days and have had this problem now 3 days. I am going to stop taking as I think this is the problem just hoping some other people had this problem so I can eliminate medical issues.

So, I bought the pure green coffee bean extract. Started taking 800mg twice/day and had absolutely no effect. No increase in energy, no weight loss and no side effects with poop. Does this stuff really work? Maybe for some people, but I am not that lucky.

I've lost 6 pounds.

Check out the findings from the National Institute of Health at http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3267522/. GCBE looks to be the real deal

is this a joke? i'm honestly beginning to think that if someone relies on a pill to lose weight then they don't deserve to lose it. Work hard. Have your own self-control rather than taking a pill that supposedly "curbs your appetite." Plenty of people on this site and other sites lose weight by exercise and self-control. Honestly. I've gotten over multiple plateaus on my own by changing up what I do. Yeah, it takes a little process of elimination work but it happens. If you're just gonna be lazy and take a pill you might as well not even try. Your magic solution won't work and you'll give up.

This isn't directed to the OP, just the thread in general.

I find the price for this product outlandish, a money grab.

Why not make it yourself. It is easy.

Just buy, organic unroasted green coffee beans and grind it up
yourself, weigh it out in grams and put it in a smoothy or
gently brew it yourself.

Facebook has a page for Green Coffee Bean Extract DIY , do it yourself.
Lots of information here, nobody trying to sell you anything but good
information.

Buying organic green coffee beans and grinding it yourself is much cheaper than paying for a bottle of it. It is easy as making a cup of coffee. The word extract is misused to confuse you. All that is in that pure coffee bean capsule is...ground up unroasted coffee beans and who knows if it is organic or not. Organic is the way to go.

I can appreciate how well you've done and the hard work it has taken for you to get to where you are. But, don't be so harsh in judging others who are just starting out on their path or have encountered road blocks and are looking for help. From what I've heard about any supplement that helps in weight loss...it is just an aid..never touted as a magic pill that you take and that's it. ..you still have to diet and exercise.. I think most people know that.

I have done rasberry ketone and green coffee bean. I had lose weight with the rasberry ketone but not with the green coffee bean. I know others that have lost weight on both of them. Each person is different. What might work for one might not work for another. I say give them try and see for yourself. Make sure they don't have fillers.

I wasn't lucky, but I found out that I was taking one with a filler. Make sure it has no filler in it.

In response to ElisaGal123 post above this post about the sad sad quote given.

This message quoted is so sad. Why would someone do this? Maybe because they are just plain angry, or feeling hopeless....depressed and felt compelled to share their dark dreary cloud?

Understanding where our food comes from, how it reacts with your body; you will learn we are all 'victims' of obesity
and bad health to the food industry. Our soils are so depleted of nutrients to fortify our crops, pesticides and genetic modification has had a negative effect of how our bodies metabolize our food. Meat, dairy, eggs poison our bodies,
our minds, every day, never mind the horrible lives animals endure before they are murdered all becomes apart of
our mind, body, and spirit after we eat it without good results.

Going organic and vegan will help a lot of our health but it is still just as easy to be a fat vegan as it is to be a fat omnivore.
The green coffee bean is what it is, derived from a 'plant'. So, just because it is encapsulated, doesn't mean it is
a pill. It is a 'supplement'. It is pretty bitter to take without the capsule and most don't like this but with a little honey,
or putting it into a smoothy helps get it down. It is also very healthy and good for you. I'm all for the natural process,
and if Mother Nature has a solution, I am listening.

the issue is that most people don't know that... that's why i get annoyed

I have been taking it for about 1 1/2 weeks. I bought mine at Sprouts at $20 for a bottle of 90. I do not know whether I have lost any weight or not but I have noticed that it make you poop alot. No less than3-4 times a day for me. I have not noticed a energy boost but I was already taking B-12 daily. Anyway, Good Luck!

Wondering what brand you found? That is a very good price, bummer no Sprouts in my area.

She wanted an opinion from those who have tried it.

I have a bridge for sale that will help you lose weight, any takers?

used them...lost like a pound & that was it...

Took them for 30 days and nothing changed... It was like Sensa- it did absolutely nothing.
It was called pure health pure coffee bean extract- bought it was walmart for a 15 day supply $10.
Right next to it was raspberry ketones- same thing Dr. Oz mentioned... Now I'm beginning to think he is loony!

It is pretty good but can be expensive . It makes you feel full . peacantia

My aunt is doing the weight watchers weigh ins. After taking the coffee bean extract along with chia seed she was down 6Lbs in 8 days. It could just be water, but who knows. I say if you want to try it go for it. The health food store also sells them. If it works for you, then who's to judge. I just find it interesting how a site that is supposed to be so positive, has so many negative people!!!

Pure health from wall mart is fake.

Dr. Oz is such a jerk. Really his show is like an infomercial. Doesn't he have enough money already? He could be doing a great public service by talking about how to be healthy and what health means. But instead he would rather hawk some goods for profit.
