What does the science say about raspberry ketones?
Raspberry ketone is an aromatic component present in raspberries and other fruits. It can also be produced synthetically in a lab.
Scientists had previously shown that pungent compounds with similar chemical structures, such as capsaicin and synephrine, had lipolytic activity – causing fat breakdown – in rats fed a high-fat diet and in in vitro fat cells.
Researchers observed that, compared to controls, raspberry ketone decreased the amount of fat in the liver and visceral adipose (abdominal fat) tissues of mice. It also significantly increased norepinephrine-induced lipolysis (the decomposition of fat) in some rat fat cells.
Researchers also tested in vitro fat cells with raspberry ketone and found that they showed greater evidence of breakdown when compared to controls.
Raspberry ketone is one of the best supplements for weight loss. It is a natural weight loss supplement that works very effectively. There are several benefits of raspberry ketone. Raspberry ketones are also very good for heart as well as circulatory system. There are no side effects of taking raspberry ketones. It contains many properties of ketones and there for used as a great supplement today.
TZ: In a 2005 study by Morimoto et al, raspberry ketone was fed at various dosages to growing mice for 10 weeks. Results indicated that mice fed a high-fat diet to induce obesity plus one or two percent raspberry ketone [approximate equivalent to 100 to 300 mg/day in humans] gained less bodyfat than control animals. Raspberry ketone also decreased the weights of the liver and visceral adipose tissues [epididymal, retroperitoneal, mesenteric], i.e., fat around the waist. Raspberry ketone has at least two anti-obesity effects: decreased absorption of dietary fat and increased norepinephine-induced lipolysis or fat breakdown. Regarding decreased fat absorption, raspberry ketone given at concentrations of 1 to 20 mg/mL after oral administration of corn oil reduced the elevation of plasma triacylglycerol in mice and inhibited pancreatic lipase in rats. This suggests raspberry ketone suppresses dietary fat absorption by inhibiting trioleoylglycerol hydrolysis. Regarding enhanced fat breakdow
