Grizzly bears and black bears generally do not eat, drink, defecate, or urinate during hibernation. Bears live off of a layer of fat built up during the summer and fall months prior to hibernation. Waste products are produced, however, instead of disposing of their metabolic waste, bears recycle it. The urea produced from fat metabolism (fatal at high levels) is broken down and the resulting nitrogen is used by the bear to build protein, which allows them to maintain muscle mass and organ tissues (Rogers 1981). Bears lose fat and may actually increase lean-body mass while hibernating due to this nitrogen recycling (Wickelgren 1988). Bears may loose 15-30 % of their body weight during hibernation (Rogers 1981).
Now Sharon, even though you are awake during this process, it could be you have some mechanism like the bear during hibernation?? I like the thought of losing fat and still increasing lean body mass,,,now that is SMART!!!
