Raspberry Ketone – the natural fat burner that lowers Adiponectin levels

Last updated on September 8th, 2013


Raspberry Ketone is advertised everywhere these days!  It is an incredibly popular natural supplement that is reputed to assist in fat burning, weight loss and many other health conditions.

It is available in pills, powders, drink mixes and even lotions. It is classed as a superfruit and is quite possibly the must have weight loss product currently in circulation

What Is Raspberry Ketone And How Does It Work

Raspberry Ketone is a naturally occurring phenol (a class of chemical compounds consisting of a hydroxyl group [—OH] bonded directly to an aromatic hydrocarbon group) that is the primary compound responsible for the smell of Raspberries.

It has been used since the 1920’s as a flavouring agent in foods, and in perfumes and cosmetics to impart a fruity aroma.  Recent scientific findings are responsible for Raspberry Ketones being cast in a new light:  fat burning miracle.

The study most often referenced by proponents of Raspberry Ketone for weight loss was conducted by scientists from the Ehime University School of Medicine in Japan.  Published in 2005, the study details how mice were fed a high fat diet and given three differing doses of Raspberry Ketone over a 10 week period, and also fed a high fat diet for 6 weeks and the same diet plus 1% Raspberry Ketones for an additional 5 weeks.

It was determined that the Raspberry Ketones alter lipid (fat) metabolism and resulted in a positive effect on both obesity and fatty liver.

Researchers theorize Raspberry Ketone causes the body to secret more Adiponectin, a protein hormone involved in metabolizing (breaking down) fatty acids and regulating glucose levels.

In adults, levels of Adiponectin are inversely correlated with body fat percentage.  This means people with more in their system tend to have a lower percentage of body fat and people with less of the hormone have higher body fat percentage.  This is why Raspberry Ketone is believed to fight obesity and promote lean body mass. The recommended dose for adults is 100-300 mg per day.

Interesting Raspberry Ketone Fact

Naturally occurring Raspberry Ketone produces yields of just 1-4 mg per 1 kg of Raspberry fruit.  This makes it one of the most expensive food flavoring compounds, and as such can cost up to $20,000 per kg, or about $10,000 per lb.

Although Raspberry Ketone can also come from cranberries and blackberries, it would take thousands of pounds of fruit to meet industry demand.  This is why the majority of Raspberry Ketone on the market is synthesized.  Synthetic Raspberry Ketone is significantly less expensive and ranges from a few dollars up to $4,000 dollars per kg ($2,000 per lb).

Raspberry Ketone Media Focus

In February of 2012, Dr. Oz featured Raspberry Ketone on an episode of his show and called it “A Fat Burner in a Bottle.”  Since then the demand for this supplement has skyrocketed.

In April of 2012, ABC news did a story about the phenomenon titled “Raspberry Ketones Frenzy Follows Dr. Oz Show”,  which describes how the supplement “has become nearly impossible to find in stores” since the segment aired.  Media celebrities Oprah Winfrey and Kim Kardashian are also reported to swear by its powerful effects.

Everyday Success Stories

Unlike most fad weight loss products with recycled testimonials and before and after photos that have been clearly altered, Raspberry Ketone is hailed as successful by ordinary people from around the globe.

The internet is full of their written and video testimonials.  What also sets these results apart is how realistic they are.   The average testimonial claims healthy weight loss achieved at a reasonable rate of 1-3 lbs per week when taken as part of a diet and exercise plan.

Possible Side Effects And Cautions

Raspberry Ketone is reported to have no side effects but consumers should remember that it has never been studied as a weight loss supplement in humans.  As a food additive, the U.S. Food and Drug administration classifies it as Generally Regarded as Safe (GRAS).

The FDA does not approve supplements.  According to their website, “manufacturers do not need to register their products with FDA or get FDA approval before producing or selling dietary supplements.”  However, any adverse reactions associated with the use of the supplement in the U.S. must be reported.

Pregnant or breastfeeding women should always consult their physician prior to using any supplement or medication.

Is It Recommended

Overall, Raspberry Ketone appears to be a natural,  safe supplement that supports  healthy fat metabolism and weight loss when ingested as part of a diet and exercise plan.

Consumers should avoid any product that promises the Raspberry Ketone it contains will result in drastic weight loss.

Additionally, there are some claims that lotions containing the supplement also promote weight loss, but there is no evidence to support this – a supplement, tablet or capsule is the most effective and efficient way of introducing the natural benefits.
