Raspberry
ketones have relativity recently reached the health market in the UK,
and are marketed as an effective weight loss supplement. This article
will explain what raspberry ketones are, and investigate the scientific
evidence for their claims.
Raspberry Ketones & Their Uses
A
raspberry ketone is a small volatile organic compound. It not only
found in raspberries, but is also found in cranberries and other
brightly colored berries. These ketones are found in extremely small
quantities in these fruits, which means that natural ketones
are extremely expensive to obtain. As a result of this raspberry ketones
can be made synthetically for a fraction of the price, but will contain
impurities.
As raspberry ketones are
volatile, they have been used for a long time in the perfume and food
industry to give a natural and fruity smell to products. They have only
recently been introduced to the supplement industry as a weight loss
supplement.
Is There Any Science Behind The Supplement?
To
date, there is no clinical evidence to support the claims that
raspberry ketones can promote weight loss, or even have any health
benefits. There are only a small number of animal studies which have
investigated the weight loss properties of raspberry ketones, and only
one has shown an ability to prevent any additional weight gain. In this
study an incredibly high dosage of raspberry ketones was used, which was
20g per kg of the body weight in raspberry ketones.
Conclusion
The
lack of evidence makes it impossible to draw any conclusions. There is
currently nothing to suggest that raspberry ketones will aid with weight
loss or provide any health benefits. Any claims suggesting they will
aid with weight loss are just marketing.
