Raspberries are famous for their substantial amount of vitamin C and antioxidants. But recent studies have shown that raspberries are also very strong fat-burners. Researchers in Japan were looking for natural fat-burning substitutes for capsaicin- a compound in peppers that causes its burning and spicy taste and has strong fat-burning properties- and they found out that raspberries have even more fat-burning properties than red pepper, and they taste much better too!
The fat-burning properties of raspberry is from its ketones compounds. Raspberry ketones are the major aromatic compounds of raspberries that cause its smell and taste. These ketones has similar structure as capsaicin.
Many claim that raspberry ketones supplements have similar fat-burning properties. As you can see in this video of the Dr. Oz show, weight loss expert and dietician Lisa Lynn illustrates the benefits of raspberry ketones by showing the people who have raspberry ketones before and after taking the supplement.
Please note that there hasn’t been any scientific research on the effects of raspberry ketones on humans and all the studies were performed on mice. So still it’s not clear that KETONES SUPPLEMENT is as effective as the fruit itself in burning fat or not.
