One thing that presumably massively influences calory-allocation may be the the prevalence of brown fat in some adult humans. I found a lot of unusual observations about my (privileged) metabolism suddenly explained by the presumed presence of it. See http://en.wikipedia.org/wiki/Brown_adipose_tissue#Presence_in_adults
There are some biases that make me favouring this explanation, and there is contradicting evidence, so I am not so sure anymore.

I found most useful (for google) the following ones:
Quotationmarks around a phrase, e.g. “less wrong” searches for the exact phrase.
the “site:address phrase” command searches for your phrase only on the specified site, e.g. site:lesswrong.com “nuclear plant”
the exclude-command “-” (minus) excludes one word from your results: rationality -rand
