When considering how Bigfoot survives in the winter, one must consider the amount of calories it would take to sustain them. Of course, the calorie consumption would be different if the Bigfoot hibernated, but if they do not, how would they obtain the food necessary to last them through the winter.
First thing to consider is does Bigfoot hibernate? There is no real data on this, and mostly because science cannot agree if Bigfoot even exists. Yes, science is not torn between the two. Recent DNA studies have indicated Bigfoot does, and does not exist. Of course I am talking only of the Dr Sykes DNA study on the Yeti and the Dr Ketchum DNA study on Bigfoot. One study seems to indicate the Yeti is a descendant from the Polar Bear, while the Bigfoot is being claimed to be a hybrid human. Of course, we may be arguing the difference between apples and oranges and the two may not even be related. However, if Yeti is a descendant from the Polar Bear, we could understand how it may be resistant to colder climates in the Himalayan Mountains of Tibet. We would be able to draw upon knowledge of how bears bulk up during the spring, summer, and fall in order to sleep away most of the winter.
The North American Bigfoot seems to be quite active during the winter. There are many reports of tracks in the snow of what appears to be a Bigfoot traveling to some location. Yes, the yeti has left tracks in the snow also, but their area is greatly snow bound year round. However, there are valleys and areas in the lower altitudes that would provide food during the summer, and man does not necessarily wish to go into the Himalayan Mountains during the winters. It would be interesting to get some data on when tracks of the Yeti are often found.
With Bigfoot, snow makes it easier to track the elusive creature, and it is quite evident the Bigfoot are out foraging for food between snow storms when the temperature plummets below freezing. Sightings rarely describe the Bigfoot as fattened up, but usually describe a very muscular creature and more like a very big pro-football linebacker. This seems to indicate that Bigfoot does not hibernate because they have very little fat reserves to survive upon during the winter. Therefore, if Bigfoot does not hibernate (no proof of this), then questions arise about diet changes, food storage, food sources, and more.
