Raspberry Ketone – What is it?
Raspberry ketone is a phenolic compound from red raspberries that gives the fruit its pleasant aroma. It is one of the compounds that give the red raspberry its antioxidant properties. It is also widely known as Red Raspberry Ketone, European Red Raspberry or RK. In scientific terms, they are referred to as Rubus Ideaus, Rubus Strigosus and Framboise Rouge.
This compound was given a safe classification by the US Food and Drug Administration. It was classified as a GRAS substance which simply means is Generally Recognized as Safe. It has also been used since the 1960’s in the Food and Cosmetic Industry as a fragrance and flavoring agent.
How does it cause weight loss?
A study on raspberry ketone and its anti-obesity action was conducted and was published in 2005. It was discovered that raspberry ketones resulted in a reduction in total body weight after 10 weeks of use, there was also a decrease in fats in the liver. This is the effect of RK at an intake of between 1 to 2 per cent of total calories consumed. This had a direct effect on the brain hormone called norepinephrine, which is also a neurotransmitter that affects the body’s ability to burn fats. Researchers observed that a combination of raspberry ketones and norepinephrine caused the fats cells to shrink than norepinephrine alone. The combination alters lipid metabolism, increasing norepinephrine induced lipolysis and fatty acid oxidation in adipocytes. The study also shows taking RK at 5 per cent of total calorie intake decreases the amount of triglycerides in the body.
A more recent study supports the previous one and it shows that RK increases the amount of adiponectin in the fat cells. Adiponectin is a protein hormone that is responsible for the regulation of a number of metabolic processes including glucose regulation and fatty acid oxidation. Adiponectin increases sensitivity of insulin. Increased insulin sensitivity equates to better metabolism which means fat is burned faster.
Why should I take Raspberry Ketone?
Technology has made our lives easier and movement has become limited finding the time to exercise is nearly impossible. And for those who do not have time for the gym, or the time to cook a healthy meal, the additional weight is inevitable. And for those who have gone quite far from the healthy weight margin, there is no alternative other than an intense work out at extended periods. The good news is that raspberry ketone supplements give people another alternative to lose weight because it lets the body metabolize faster than it would with exercise alone. It is true that nothing beats proper diet and a regular exercise to get the healthy body we all want but some of us needs a lot more boost and raspberry ketone supplements do just that.
