Ever since Dr. Oz sang the praises of a supplement called raspberry ketone, I've had many clients as me about the product. On his show, Dr. Oz called the supplement, "miracle in a bottle to burn fat". As you can imagine, product promptly flew off store shelves.
Unfortunately, raspberry ketone is not a magic bullet. While one study hints that it might help mice trim fat, it has never been tested in humans. And keep in mind the mice were fed 2 percent of their body weight as raspberry ketone, an amount that would translate into far more than a person would consume on a daily basis.
Raspberry ketone is a natural compound found in raspberries that give them their distinct smell. Most raspberry ketone supplements, however, are made synthetically.
Plus, there are some emerging safety concerns. Raspberry ketone's structure is similar to the stimulant synephrine. In the U.S. there have been reports of heart palpitations and reduced warfarin (a blood thinner) effects in people taking raspberry ketone.
Bottom line: It takes more than popping a supplement to lose weight. I'm afraid the old adage, "calories in, calories out" still holds.
