Raspberry ketone is a natural phenolic
compound that is the primary aroma compound of red raspberries. It is
used in perfumery, in cosmetics, and as a food additive to impart a
In plants, raspberry ketone is synthesized from coumaroyl-CoA.But since
the natural abundance of raspberry ketone is very low, it is prepared
industrially by a variety of methods from chemical intermediates.When
given to mice in high doses (up to 2% of food intake), raspberry ketone
has been shown to prevent high-fat-diet-induced elevations in body
weight.This effect is reported to stem from the alteration of lipid
metabolism, increasing norepinephrine-induced lipolysis. Although
products containing this compound are marketed for weight loss, this
effect has not been studied in humans.
Raspberry ketone, an aromatic substance in raspberries found to reduce
Raspberry ketone is an aromatic compound found all red raspberries (Rubus
idaeus) which is extensively used in perfumery. It's chemical structure
is similar to that of zingerone, a ginger extract which reduced obesity
and is analysed elsewhere on this website. It is also similar to that of
capsaicin (the chemical that gives hot chili peppers their "burning"
quality), to synephrine (a substance found in orange peel and known to
help reduce fat and fluid retention) and evodiamine (another fat loss
ingredient). All these chemicals, including raspberry ketone interact
with fat cells and induce fat loss via similar mechanisms.
"Anti-obese action of raspberry ketone"
In 2004 a group of Japanese researchers examined the anti-obesity action
of raspberry ketone in mice. To test the effect on obesity, the
researches in one experiment fed mice a high-fat diet including 0.5, 1,
or 2% of raspberry ketone for 10 weeks. In another experiment mice were
given a high-fat diet for 6 weeks and then fed the same high-fat diet
containing 1% of raspberry ketone for the next 5 weeks.
After 11 weeks the results were pretty amazing. Raspberry ketone did
indeed prevent the high-fat-diet-induced fat gain in the first
experiment, and decreased the fat accumulation produced by 6 weeks of
high fat diet in the second experiment. In addition, the raspberry
ketone decreased the amounts of fat accumulated in the liver due to the
high fat diet, thereby improving fatty liver. The researchers concluded
that this obesity preventing and reducing effect was due to the
potentiation of the norepinephrine-induced lipolysis (=fat breakdown) in
Norepinephrine is produced by the body when we exercise, therefore the
best time to consume raspberries or apply a raspberry ketone cream on
areas with excess fat, is immediately before and/or after exercise. This
is when the raspberry ketone can really perform it’s magic.
