Can a concentrated dose of one of these “super” plants really help you lose weight? Our experts tend to say not likely, at least not anything long term. However, the growing popularity of raspberry ketones (since Dr. Oz’s “miracle fat burner” endorsement last week) has us looking back at some of the biggest supplement fads in recent years.
Here, we take a look at three supplements that promise weight loss: raspberry ketone, hoodia and acai.
This supplement recently got major attention when Dr. Oz touted raspberry ketone as a fat-burner that can help anyone lose weight. Although scarce in nature, the synthetic raspberry ketone is relatively inexpensive. The supplement is basically a stimulant that works by increasing the body’s production of norepinepherine and adiponectin. Norepinepherine boosts metabolism by raising the body’s temperature, while adiponectin makes glucose less likely to be stored. However, there haven’t been any controlled studies on humans showing that these effects result in weight loss. “Like other diet pills that have an effect on body temperature and metabolism I would think that these products would only be effective for a short period of time and would eventually have to be discontinued,” says Dr. Sarah G. Khan, DietsInReview’s resident pharmacist.
