The article is mainly concerned with very long space trips. Weight
loss during hibernation is about five pounds per year, which becomes
significant on multi-year trips.
Travel time to Mars would be about 9 months, so the weight loss would
only be about four pounds during hibernation. This should not be a
problem for most people. Muscle weakness might be significant
though. Waking up early to do fitness training should fix that.
