What are raspberry ketones?
This is a natural substance that is responsible for the powerful aroma in red raspberries. This substance is also found in cranberries, blackberries and kiwis. They are also used as flavorants in processed foods and soft drinks.
How do They Work?
Researchers were interested in raspberry ketone when they noticed its molecular structure. It looked similar to synephrine and capsaicin (mainly found in chilli). Several studies have shown the two molecules boost metabolism of the body and so the raspberry was speculated to do the same.
The researcher did some test on rats and found it to increase breakdown of fat and more release of the adiponectin hormone.

However, the dosage given to the rats were insanely high and cannot be compared to the one taken by a human. There hasn’t been any research on the effect of raspberry ketones in human. It can be assumed that raspberry is like one of the other weight loss products.
