Dr Oz Green Coffee Bean Extract Review

HOW WILL CHLOROGENIC ACID HELP YOU LOSE WEIGHT?

.

A: Restrict the absorption of high glucose foods that make you fat:

When glucose rich carbs and fats enter the blood system through digestion they are very hard to break down. The green coffee beans GCA (chlorogenic acid) as demonstrated through a randomized, double-blind, placebo-controlled, linear dose, 22 week crossover study significantly deprived glucose absorption which is one possibility why the subjects average BMI dropped 10.3%. (See here).

Under a separate 12 week study by Thom on 40 obese volunteers, results showed GCA caused a significant difference in weight reduction of the action group whose mean figure was 5.4kg – 10%, versus the placebo group who lost 1.7kg – 4%, the cause of which resulted from the reduced absorption of certain types of sugars from the gastrointestinal tract. (See here)

The GCA capsule under question contains a standard green coffee bean extract of total chlorogenic close to 46%, other hydroxycinnamic acids known to provide antioxidant health benefits – 9%, 2.6% caffeine with the remaining volume consisting of GCBE polyphenols.

B:Release fatty acids from fat stores by increasing your metabolism:

There are certain chlorogenic acids that are known to increase fat and glucose metabolism. The 22 week crossover study also demonstrated that GCA had a significant influence on the subjects glucose metabolism.

Cited by Joe A Vinson, Bryan R Burnham and Mysore V Nagendran on their publication of the GCA findings on the National Center for Biotechnology Information website,  they quote:

…GCA with a weight loss of 8 kg (10.5%) and a BMI reduction of almost 3 makes the product superior to the prescription drugs. Weight loss of 5%–10% of initial body weight reduces cardiovascular and metabolic health risks associated with obesity”

This conclusion is drawn from a publication which summarizes the long term efficacy of anti-obesity drugs at reducing weight and improving health status. (See here)

C:Activate fat metabolism in the liver & lower triglyceride levels:

The results of this study were much more dramatic for weight reduction and BMI than previous green coffee extract studies have shown. All of the study group had a BMI greater than 25 – a normal BMI ranges between 18.5 and 25, and once the trial was completed, the BMI of 6 participants fell between the normal range –  all 16 subjects lowered their BMI.

In part this could be due to the lowering of lipid levels in the liver. A previous Japanese study conducted on mice into the efficacy coffee polyphenols have on metabolism, concluded that GCA is possibly responsible for activating fat metabolism in the liver and thus effective against fat accumulation and weight gain.

By improving lipid metabolism, you lower triglyceride levels in the liver. A triglyceride in laymen’s terms is a concoction of three different fatty acids, harmful to your health that contribute heavily to weight gain. GCA is thus shown to increase the speed at which fat is burned in the liver and turned into energy meaning you potentially lose weight faster depending on your diet.

Note: Green coffee bean extract is not an appetite suppressant.

Subjects’ trial results:

Average weight loss – 17lbs
Mean body weight reduction – 10.5%
Mean BMI drop – 10.3% BMI
Average total fat loss – 15.8%

 

How to choose the correct green coffee supplement that matches the same measures used by the trial subjects:

It can be somewhat confusing when it comes to evaluating the exact contents of one of these nutraceuticals.

The 22 week crossover study concentrated on a standard green coffee extract supplied by Applied Food Sciences under the trade name GCA®. , which contained  high concentrations of chlorogenic acids known for influencing fat and glucose metabolism.

To be exact the standard GCA assayed contained 45.9% chlorogenic acids and other hydroxycinnamic acids that are known to include additional anti-oxidant health benefits totaling 56.66%  with caffeine weighing in at 2 to 4% and the remainder of the ingredients were the polyphenols extracted from the green coffee bean that you will find in most GCBE’s but different to a chlorogenic acid.

The study created 2 types of capsule: one which contained 350 mg of GCA  - the high dose which the subject took 3 times a day orally and then the same capsule was taken twice a day for the low dose condition. The second pill contained an inactive powder taken 3 times a day.

If each 350 mg capsule contained close to 46% chlorogenic acids, you should therefore choose a supplement which contains approximately 160 mg of chlorogenic acid per capsule.

7 popular GCBE products of 2014 have been chosen below ranked in order of their Chlorogenic Acid content in mg, listed also is their overall green coffee bean extract percentage, other additional ingredients which can influence fat and sugar metabolism, the number of capsules per bottle and price.

Synopsis of the medical trial conducted on GCA – the trade name for a standardized green coffee bean extract by Applied Food Sciences

16 subjects were chosen for the trial which lasted 22 weeks, 8 men and 8 women between the ages of 22 to 45 who were classified as pre-obese or overweight then went through three separate cycles in random order: 4 weeks taking 1050mg of GCA – a large dose, 700mg of GCA – a lower dose, and then a placebo capsule of inactive powder. Each 4 week cycle was separated with a 2 week wash-out interval.

The subjects exercise plan, consumption of calories, carbohydrates, fats and protein did not marginally change throughout the 22 week period.

Below is a screenshot of the results published on the National Center for Biotechnology Information website.

 Results of the trial:

On average, participants lost 17lbs over a 22 week period – a 10.5% decrease in body weight, a 10.3% BMI drop and a 15.8% total loss in body fat, but that could have been greater as is argued on the publication page if they had not undergone a lower dosage as well as a placebo period.

How to replicate trial results:

First off you need to stick to a low fat diet as the participants did throughout the course – Below is a screenshot of the diet profile that the 16 pre-obese subjects followed from the beginning and during the 3 arms of the study which lists the percentage of daily calories consumed from fat, protein and carbohydrate intake:

Diet plan for 16 preobese subjects on chlorogenic acid for 22 weeks

As you can see your mean daily calorie intake doesn’t veer much off the 2400 mark along all three arms, plus the study did not prescribe two separate daily requirements for each sex.

Fat intake is low – averaging 25% or just under for the day, where your carbohydrate intake takes up roughly a third of your meals.

Protein is also surprisingly low at around 15%. Lean meats are often recommended for healthy dieting as they have a high thermogenic effect, meaning you burn approximately 30% of the calories that are in the protein through the digestive process – so a 400 calorie chicken breast will require  about 130 calories to breakdown.

However some lean proteins can be very high in both cholesterol and saturated fats so it’s important to remove the fat, skin and grizzle so you’re able to keep an accurate track of just how many calories your consuming.

Fresh seafood, eggs, legumes, nuts, beans and seeds are alternative protein sources which make for an overall healthier diet.

 

Why a rich carbohydrate diet MUST contain low glycemic carbs:

To start a rich carbohydrate diet you need to choose the right carbohydrates that are low on the Glycemic Index (GI)see here.

The index is ranked 0 to 100, where foods below 55 are considered the healthiest option.

Glycemic foods are ranked in relation to the impact they have in raising sugar levels in the blood, so those closest to zero are considered the safest and above 70 the riskiest.

Here’s an interesting article published on the Huffington Post that goes into further detail on the types of food that can make up a high carb/low glycemic diet.
