While you may have heard of the weight loss benefits of regular coffee, you may be unfamiliar with the surprising potency of green coffee as a weight-loss stimulant. The new discovery by Dr Vinson, professor at University of Scranton, was presented last month in the 243rd National Meeting & Exposition of the American Chemical Society in San Diego, CA.

What is Green Coffee?

Green coffee is made from unroasted coffee beans; unlike traditional coffee, however, green coffee is extremely bitter. That’s sad news for coffee lovers, but the good news, according to professor Vinson’s announcement, is that you can reap substantial weight loss benefits from taking green coffee—just not in your coffee cup.

To reap the health and weight-loss benefits of green coffee, the participants in Dr Vinson’s study took their java in a capsule form that contained ground green coffee beans. Green coffee is extremely bitter which is why it’s better to swallow it as a capsule than mix the powder with water and drink it.

How Does Green Coffee Work for Weight Loss?

Research by Dr. Joe Vinson has recently pointed to the weight loss effects of green coffee. They are primarily due to the high amount of chlorogenic acid, a polyphenol with strong antioxidant properties. It is thought to reduce blood sugar absorption and prevent high blood sugar peaks. Interestingly, roasting coffee beans while it leads to that rich flavor and aroma we all love also breaks down the chlorogenic acid content of the bean. Leaving the coffee in its natural state by not roasting it allows us all to reap the full power of the bean.

Dr. Vinson’s study involved sixteen overweight males and females. Participants did not alter their diet or exercise routines; they simply took one pill of green coffee powder (ground green coffee beans) before every meal. Over the course of 22 weeks, the study saw participants shed about 17 pounds each, equaling about a 10% total body weight loss overall. The weight loss was due to fat loss, as participants’ body fat decreased by 16%. Absolutely no side effects were observed. I don’t know about you, but I’ll take that!

While Dr. Vinson’s study is small and research in a larger scale (involving over 60 people) is still pending, it has already led to some buzz about green coffee. The Huffington Post reported on Dr. Vinson’s study on green coffee extract, dubbing green coffee as green tea’s “slimming rival.”

Even the major coffee company Starbucks has jumped on the bandwagon, introducing its first green coffee health drinks earlier this year.

So, How Can You Reap the Weight Loss Benefits of Green Coffee?

The first steps are, of course, maintaining a healthy diet and exercising regularly. (This should go without saying, right?) But, to kick-start your weight loss goals, you may want to consider adding green coffee extract to your daily routine. You can either take it in a pill form or just prepare it yourself by grinding some fresh green coffee beans with a grinder.

How many would be enough to trigger weight loss? Well, in terms of the caffeine content, “the three pills that were used in the study daily will give you about half the caffeine of a cup of coffee. So, the caffeine level is low and it’s equivalent to half a cup of coffee” was Dr Vinson’s answer when asked how many coffee beans one should take to see a similar weight loss effect. So, that would be about 10 ground coffee beans 3 times a day.

green coffee extractYou can get green coffee bean extract from Amazon or other reputable health supplement sources. Dr. Vinson advises taking one capsule about thirty minutes before each meal, with a full glass of water to help with absorption.

The key in Dr. Vinson’s study is that participants took a high dose of the coffee. Other similar studies showed minimal success with participants taking lower doses of the green coffee extract. Dr. Vinson’s study had participants take a higher total dose (1050 mg total), spread out over the day in three pills. Spreading the doses works in two major ways:

  • It breaks down the total dose into three manageable portions.
  • Taking more frequent, smaller doses help keeps the level of chlorogenic acid (and, in theory, your blood sugar and metabolic levels) stable throughout the day in the body—and that’s the basis of a sustained weight loss effect.
So, if you want to experiment yourself, make sure you take it 3 times a day, too. As with any weight-loss routine, please be sure to check with your doctor before beginning.

Good luck in your weight-loss efforts!

  1. This is fascinating. What is the caffeine content of this amount of green coffee? I am extremely sensitive to caffeine.

    • Three green coffee pills are equivalent to half a cup of coffee so the caffeine content is quite low.

  2. Hello Karali and Daisy,
    Thank you for your comment. Yes, you shouldn’t worry about the caffeine content in the dose of green coffee poweder that promotes weight loss.

  3. So the weight loss is from blood sugar being not being absorbed, and not from fat being burned as with capsiplex?
    Someone who grows coffee beans could make his own natural weight-loss product by buying empty capsules from a manufacturer and filling them himself. Grind 10 beans three times a day. Not hard at all.

  4. Hi Joanna,

    yes, that’s correct. According to Dr Vinson, green coffee promotes weight loss is by means of absorption of certain nutrients. It does not appear to increase the metabolism and burn fat, Further research is being conducted that will investigate the mechanism of action.

    Yes, you don’t even need to buy the pills that are currently in the market. You can grind a few beans and shallow the powder with a glass of water, 3 times a day. I tried it. It’s not that bitter. You do need to grind the beans very well, however, so that you will make a fine powder, otherwise your gut will not absorb it.

  5. Hi Matthew!

    Just have questions!
    How many beans can you grind? does it have to be powder like? do you drink this coffee cold or hot? do you have to grind the beans every time you want to drink the coffee?
    please somebody help!

  6. I forgot to ask!
    how many cups per day?


  7. Just have a question?

    How much powder do you use per water and would the water be hot or cold?


  8. Hello everybody,

    here is the link to Dr Vinson’s speech in American Chemical Society’s recent meeting. Dr Vinson is the professor who spearheads the project of green coffee beans. He answers many questions.
