There is a new ingredient in the weight loss world that is getting a boatload of attention.
This nutrient has been around since 1965, but until recently, was not researched extensively.
The nutrient is raspberry ketones (which has been made famous by Dr. Oz).
Raspberry ketones, otherwise known as rheosmin, has been shown in research to increase fat metabolism in your fat cells.
Research suggests that aromatic components in red raspberries work by increasing enzyme activity, increasing oxygen consumption, and increasing heat production in some fat cells in your body.
Put together, this may lead to lower levels of fatty acids being stored in your fat cells – resulting in more weight loss.
Plus, raspberry ketones has also been linked to an increase in the expression of adiponectin levels in your blood, which could stimulate increased energy expenditure.
According to one study published in Planta Medica, exposure of raspberry ketones in fat cells may be linked to increased fat oxidation and adiponectin levels.
Let me explain…
Raspberry Ketones, Adiponectin, and Fat Burning
Adiponectin, which is a protein secreted exclusively from your fat cells, has been linked to increased fatty-acid oxidation and fatty-acid breakdown.
It has been shown to be decreased in overweight or obese individuals, but losing weight has been shown to dramatically increase your levels.
Adiponectin has been shown to impair your immature fats cells (pre-adipocytes) from turning into mature, full-fledged fat cells. Plus, it may increase energy expenditure.
Raspberry ketones, according to some clinical studies, has been shown to raise adiponectin levels, which could partly explain the powerful effects of raspberry ketones.
The author of this study aimed to evaluate the effects of raspberry ketones on the expression and secretion of adiponectin, lipolysis, and fatty-acid oxidation in white fat cells.
White fat cells (different than brown, beige, or visceral fat) are cells that store extra fatty acids circulating in your blood for later use. They are also responsible for hormone and cytokine secretion, which makes fat cells an endocrine organ in your body.
The researchers administered raspberry ketones to white adipose fat cells.
They discovered that raspberry ketones increased lipolysis significantly in white fat cells; plus, it increased the expression and secretion of adiponectin in those same cells.
Also, he noted that raspberry ketones was able to increase fat oxidation and suppress fat accumulation in those very same fat cells.
From their work, they concluded that raspberry ketones showed promise as an herbal medicine due to their biological activities in promoting greater lipid metabolism in white fat cells.
Raspberry ketones, the aromatic polyphenol found in red raspberries, has received tremendous media exposure as of late due to their ability to improve weight loss results, and rightly so.
Raspberry ketones may increase fatty-acid oxidation, increase lipolysis, and increase the expression and secretion of adiponectin (powerful adipokine released by your fat cells).
In fact, the results of this study showed that raspberry ketones, when administered to white fat cells, could be responsible for the increase in adiponectin levels, fat burning, and prevention of fat being stored in the fat cells.
Raspberry ketones, along with a balanced diet and sound exercise program,may increase fat burning and reduce overall fat accumulation in your cells.
