Raspberry ketone is a chemical compound, responsible for giving raspberries their potent, pleasant aroma. It is been used as a flavouring and fragrance agent in processed foods and cosmetics.
Raspberry ketone is said to increase the body's production of adiponectin, a protein-hormone secreted from adipose (fat) tissue. Adiponectin modulates various metabolic processes in the body, and is involved with glucose and fat metabolism. It enhances metabolism, stabilise blood sugar levels and helps to eliminate fat storage in the body. Studies have shown that low adiponectin levels are associated with a higher risk of obesity, type 2 diabetes, insulin resistance, metabolic syndrome, fatty liver and even heart disease.
Raspberry ketones also appears to improve the fatburning ability of the adrenal hormone norepinephrine, which affects metabolism.
Due to its antioxidant properties, Raspberry ketones could protect against disease and cell damage, and demonstrate anti-cancer benefits.
The molecular structure of raspberry ketones looks very similar to two other molecules, capsaicin (found in chili pepper) and synephrine (a stimulant). Several studies have demonstrated these two molecules to boost metabolism.
How it works:
Raspberry ketones is purported to work in two ways:
Firstly it appears to increase lipolysis, by making the cells more sensitive to the effects of the hormone and neurotransmitter, norephinephrine, thus in effect, enhancing its fat burning abilities.
Secondly it increases the secretion of adiponectin, a protein-hormone created by adipocytes (fat cells), which helps to break down fat, and regulates metabolism and blood sugar levels.
