The fish are often "conditioned" (starved) before they are transported to reduce their metabolism and increase packing density, and the water can be cooled to further reduce metabolism.

But all the care of the somnolents had to be done by hand-turning them, massaging them, checking on blood sugar, testing the slow-motion heart actions, all the tests and services necessary to make sure that extremely reduced metabolism does not slide over into death.

Muscle increases your resting metabolic rate, so losing too much muscle reduces metabolism.

Starvation response in animals is a set of adaptive biochemical and physiological changes that reduce metabolism in response to a lack of food.

During the hibernation season, this animal shows strongly reduced metabolism each day during the rest phase while they revert to endothermic metabolism during their active phase, leading to normal euthermic body temperatures (around 38C).

During the winter it goes into deep torpor and hibernation to save energy and reduce metabolism before emerging, as the temperature increases, to mate.

This is achieved by reducing myocardial metabolism through a reduction in cardiac work load and by the use of hypothermia.

Acidification has multiple implications on marine life such as physiological sensitivities, reduced metabolism, decreased oxygen uptake and reproductive success.

Blackstone et al. have induced hibernation in mice by the astonishingly-simple expedient of exposing them to hydrogen sulfide50; this gums up their cellular machinery enough to reduce metabolism by 90%.

Stasis, cold sleep, hibernation, hypothermia, reduced metabolism, call it what you will- the logistics-medicine research teams had found a way to stack people like cordwood and use them when needed.
