The researchers mention in other sources: "Interestingly adipose fat, most likely from the ibex, made up about half of the stomach contents. The team says this amount was unexpected, but it makes sense given he was living in such a hostile climate." "The high and cold environment is particularly challenging for the human physiology and requires optimal nutrient supply to avoid rapid starvation and energy loss," says Albert Zink, an author of the study. "The Iceman seemed to have been fully aware that fat represents an excellent energy source."
