Can you really expect to lose weight by supplementing with green coffee bean extract and raspberry ketones? This article outlines the research and what you can really expect when you use these supplements to help lose weight.

First and foremost; yes, these supplements will help you lose weight. Equally as important, they promote fat burning while sparing lean (muscle) tissue. How do they work? Let’s review.

Scientists discovered the weight loss benefits of green coffee bean extract after realizing that coffee itself seemed to be healthy. After reviewing large epidemiological studies on thousands of people they realized that people who drank coffee seemed to have healthier blood sugar levels and fewer cardiovascular issues. In fact the more coffee they drank, the bigger the benefits seemed to be. Then they realized that coffee drinkers were thinner! These findings sparked tremendous excitement.

Scientists wondered: was it the caffeine that was causing these beneficial findings? It turns out that it wasn’t as decaffeinated coffee seemed to offer similar benefits. After much experimentation, researchers found coffee’s Holy Grail; it was a phytonutrient called chlorogenic acid. Interestingly, most of the chlorogenic acid in coffee is destroyed in the roasting process.

This gave scientists and interesting idea. Might an extract from the green coffee bean, with higher chlorogenic acid content, have even greater benefits? Might green coffee bean extract promote healthy blood sugar and cardiovascular health better? Might it support fat burning and weight loss better than regular coffee?
Green Coffee Bean Extract

Fortunately, the studies are done and the answers are in: Yes, yes and yes! Green coffee bean extract does support healthy blood sugar levels, it does cause us to mobilize and burn more fat and yes…it does help us to lose weight! And not just a little…the studies show that you should expect substantial weight loss when you supplement properly with green coffee bean extract. Let’s look at some of the research.
For the sake of brevity I will review two recent studies. The first study appeared in the 1/17/12 issue of Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy. Researchers worked with 16 overweight patients in a 22 week crossover study. The material used for this study was GCA® green coffee bean extract supplied by Applied Food Sciences Inc (Austin, TX). Participants were instructed not to change their normal diet or exercise habits. By the end of the study, participants lost on average 17.5 lbs, their body mass index (BMI) went down substantially and their body fat was markedly reduced. Importantly scientists were able to determine that the participants lost weight during the supplementation periods on both low (700mgs/day) and high dose (1,050mgs/day) green coffee bean extract but not while on placebo.In a European study, published in the journal Phytotherapy (Phytotherapie) number 4, 2006, researchers used 400 mgs of Svetol brand green coffee bean extract with 50 participants aged 19-75 during the course of a 60 day placebo controlled study. Interestingly, in this study scientist tried to mimic what happens when people diet by asking participants to reduce their daily caloric intake by 500 calories. Both groups lost weight, however those on Svetol green coffee bean extract lost considerably more. The group on placebo lost 5 lbs. while the group on Svetol lost 11 lbs! In addition the BMI of the group on Svetol green coffee bean extract went down by 5.7% and the ratio of lean (muscle) mass to fat mass increased by 4%. This shows that the green coffee bean extract caused participants to lose weight by increasing fat burning while sparing muscle tissue (exactly what you want when losing weight). The participants took 1 capsule containing 200mgs of Svetol green coffee bean extract with each of their 2 biggest meals. To purchase either of my 2 favorite supplementsclick here, but read on for more critical fat burning/weight loss information.

Green coffee bean extract was recently reviewed by the Dr. Oz show so there is a tremendous amount of hype, especially on the internet. Some sites are selling green coffee bean extract that has never been studied in people. There are the only 2 brands of green coffee bean extract with human studies. Therefore when using green coffee bean extract for weight loss, make sure that you are using one of these brands: Svetol or GCA®. Both of these are made by excellent manufactures. Both have good human studies and most importantly both have zero negative side effects. In fact along with the weight loss and fat burning you get side benefits in terms of health blood sugar levels and cardiovascular support.

The results of these and several other studies are so significant, so impressive, I think it’s worth a moment to elucidate the modes of action provided by green coffee bean extract to support health blood sugar levels, fat burning and weight loss.

First, the chlorogenic acid (from green coffee bean extract) reduces the amount of sugar absorbed in the small intestine by disturbing something called the sodium potassium pump. This reduces the rise in blood sugar after a meal. Normally when blood sugar increases the pancreas produces insulin to drive the sugar from our blood stream into our cells. In addition insulin acts as a fat storage hormone instructing the fat cells to store more fat. In the presence of green coffee bean extract we absorb less sugar and therefore keep insulin levels lower and store less fat. If this were the only mode of action provided by green coffee bean extract it would be worth utilizing, however there is a second, equally important mode of action.

The chlorogenic acid makes its way to the liver where it slows the normal release of stored sugar into the blood stream. Under normal conditions the liver stores much of the sugar that we absorb from the food we eat, to be released when needed to feed our cells. A couple of hours after a meal our blood sugar levels begin to drop. This causes our pancreas to release a hormone called glucagon. Glucagon signals to the liver to release its stored sugar to feed our cells. However, in the presence of chlorogenic acid this process is markedly reduced. As the blood sugar drops (and the liver is not releasing its stores of glucose) glucagon causes fat cells to release fat as an alternate fuel source to feed our cells. Due to this action we are mobilizing more fat to be burned as energy.

To review: Chlorogenic acid from green coffee bean extract reduces the absorption of some of the sugar from the food we eat in the small intestine reducing spikes in blood sugar and insulin. In addition it causes the release of fat from our fat cells to be burned as fuel to feed our cells. These are two exciting properties that help us to lose weight, but they won’t happen effectively unless we supplement properly.

Chlorogenic acid is a plant nutrient and gets broken down by our normal digestive response. Therefore, in order to achieve the best results take green coffee bean extract with your 2 or 3 biggest meals. In this way the chlorogenic acid will be available to provide these benefits throughout the day. If you simply take 2 or 3 capsules in the morning instead of spacing them out you will not achieve the same results.
I carry both of these studied brands of green coffee bean extract on my site. Click here if you would like to order… however, I want to cover another weight loss nutrient that has also recently been featured on the Dr. Oz show. This nutrient is called Raspberry Ketone and it comes from raspberries.

Raspberry Ketones (RKs) have less research than green coffee bean extract. In fact there is only one human study. Most of the research on raspberry ketones (RKs) has been performed on animals, yet it is quite impressive. Based on the research, RKs have 3 basic modes of action, all targeting fat. First, RKs reduces the absorption of fat from the small intestine. Second, RKs increase the metabolic rate of brown fat, known as therogenisis. This process produces more heat thereby burning more calories. Third, RKs cause white (storage) fat to increase a process known as lipolysis. This process causes storage fat to be broken down into smaller pieces to be burned as energy.

The human study seems to confirm that indeed RKs promote fat burning in people as well. This was a proprietary study funded by Integrity Inc. makers of a raspberry ketone supplement called Razberi-K. It was performed double blind by Ohio Research Group and conducted by Dr. Tim Zigenfuss. Importantly, this is the only human research on RKs. Scientist had 10 people perform several exercises. Some of them got Razberi-K while others received a placebo. After exercise the participants who received Razberi-K burned significantly more fat. Keep in mind that this is a small study; however, it does indicate that people are receiving benefits similar to the animal studies. Importantly there were no negative side effects in the human or animal studies.

Based on these studies, and the seemingly endless desire for a weight loss supplement that does not have any negative side effects, I have combined these 2 ingredients into one powerful weight loss supplement with the help of my favorite vitamin company: Purity Products. The combined product is called SvelteMelt and 2 capsules combine 400 mgs of Svetol (the amount used in the study I illustrated above) and 100 mgs of Razberi-K. SvelteMelt also provides 1,000 IU’s of vitamin D-3 which promotes healthy body composition. In addition, vitamin D-3 promotes strong bones and healthy immunity along with joint and muscle comfort.
SvelteMelt is my favorite weight loss nutrient and my patients are thrilled with it. If you would like to try it simply click here to purchase at my website. Each bottle contains a one month supply and costs $34.95. Based on the studies outlined above, if you try and adopt healthier eating habits and get similar results to the study participants, you should expect to lose 11lbs during the next 60 days.

If you would prefer to save a few dollars, for 19.94 per month you can use Source Naturals Green Coffee Extract which features GCA® but has no raspberrging your diet or exercise habits.I want everyone to understand; for best results, in terms of weight loss and overall health, it is important to exercise regularly and eat healthy. Work up to 30-60 minutes of moderate to vigorous exercise most days of the week. Try to eat more healthy fruits, vegetables and animal protein such as chicken, turkey, fish and even lean meats. Cut out some of the breads, pastas, muffins, bagels and junk food. Completely cut out soda and moderate sweetened drinks and fruit juices. If you follow these rules you can expect wonderful results.

Eat right, exercise, maintain a positive mental attitude and supplement wisely. That’s how we’ll age youthfully, together.
