If someone put you in a centrifuge — for an entire year — would you lose weight?
An essay by someone named Sarah argues, that “Centrifugation makes animals smaller, leaner, more muscular, and denser-boned.” The essay gives many examples. Here are two of those examples:
Female rats exposed to 3.5 or 4.7 G for one year showed “marked depletion of body-fat depots” and “significant decrease in kidney and liver lipids.”…
The drop in body fat from centrifugation can be quite large; chickens went from 13% body fat to 3% body fat at 3G, and mice have a 55% drop in total body fat after 8 weeks of 2G exposure.
Here are the studies that produced those, uh, results:
 Oyama, J., and B. Zeitman. “Tissue composition of rats exposed to chronic centrifugation.” American Journal of Physiology–Legacy Content 213.5 (1967): 1305-1310.
Fuller, Patrick M., et al. “Neurovestibular modulation of circadian and homeostatic regulation: vestibulohypothalamic connection?.” Proceedings of the National Academy of Sciences 99.24 (2002): 15723-15728.
A question raised, but not stated, by these studies: If you rode in a centrifuge for a year, or even for eight weeks, would you inevitably lose not just weight, but also all hope? Would a rat, or a chicken?
