Vibrate to Keep Fat Off? Study Weighs In
In Lab Test, Mice Avoid Adding Fat by Standing on a Low-Vibration Platform
Oct. 22, 2007 -- Subtle vibrations may help keep body fat in check, a new
The study isn't about fat-jiggling gizmos peddled on TV or the Internet.
Instead, it's about a platform that vibrates so mildly that it's barely
The researchers -- who included C.T. Rubin, PhD, of New York's Stony Brook
University -- placed mice on the low-vibration platform for 15 minutes, five
days a week, for 15 weeks.
For comparison, Rubin's team put other mice on a platform that didn't
All of the mice ate the same amount of food. But the mice in the
non-vibration group wound up with bigger torsos at the end of the study.
Why would vibrations affect fat? The answer might lie in stem cells in bone
Certain stem cells in bone marrow can give rise to fat cells. Vibrations may
interfere with that process, note Rubin and colleagues, citing further lab
tests in mice.
Rubin founded and consults for Juvent Medical Inc., which is developing
health products based on the vibration technology.
Rubin and two of his fellow researchers have submitted a provisional patent
for the vibration technology.
The study appears in this week's early online edition of Proceedings of
the National Academy of Sciences.
