Raspberry Ketones – What This Berry Extract Can Mean for Your Health and Weight-Loss
Raspberry ketones are a natural phenolic and an active compound of the red raspberry. As well as being used to flavor and color food, raspberry ketone is found in cosmetics and perfume. Although popular, it is not cheap and people who use the phenolic often pay upwards of $20, 000 per kilo. The Food and Drug Administration (FDA) carried out a full investigation in 1965, to check how safe raspberry ketone was to the general population. Following the investigation, it was given the FDA GRAS status, which means it has been certified as safe for use.
Over the last five years, raspberry ketones have been linked with weight loss. According to a Life Science study in 2005, ketones are responsible for increasing the breakdown of fat in the human body. A 2008 study also revealed that ketone extracted from raspberries contain certain antioxidants that are similar to those found in synephrine and capsaicin. It is these antioxidants that are believed to help convert fat into energy. It is also thought to increase a person’s energy levels, again helping with weight loss through an increased stamina during exercise. The efficacy of this berry-extracted ketone is believed to double when taken with acai berry and green tea.
A study carried out by Ehime University revealed the possibility that raspberry ketones may be beneficial to females suffering from breast cancer. This is due again to antioxidants, which scientists refer to as anti-cancer agents. While it will not cure cancer, it is believed to improve a female’s chances of surviving cancer following treatment.
The antioxidants contained in raspberry ketones also play a key role in the body’s protection against cell damage and diseases. The supplement encourages the body to release a certain hormone that protects against type-2 diabetes. It can also help reduce the build-up of fatty plaque in the walls of the liver and arteries. This reduces a person’s chances of suffering from serious liver conditions, such as cirrhosis and cancer.
One of the biggest benefits associated with raspberry ketones is the fact they take very little time to take effect on the body. Taken regularly and combined with an exercise plan and a healthy diet, it has been linked to weight loss and improved health in as little as two weeks, according to a Harvard University study.
Studies back raspberry ketones as being instrumental in weight loss, illness prevention, and an overall improvement in a person’s wellbeing, however, there are still certain things to consider. For example, for an individual to lose a significant amount of weight while using the berry ketone extract, they would have to consume an entire raspberry bush. Considering the expense of ketones, this may not really be an option for a weight-loss supplement. A 2005 study that took place in Switzerland, saw scientists feed ketones to several mice. The results appeared to indicate that rather than help break down fat, the ketones hindered the growth of fat cells. While this would lead to weight loss, there is potential health issues involved too. Studies also indicated that raspberry ketone dosage would have to be at least triple the recommended dose, to improve a person’s energy levels to a noticeable degree. Fortunately however, with time and technology the production cost of raspberry ketone has been significantly reduced, making it a much more affordable weight loss supplement.
