What is a calo­rie?

Triathlon Magazine Canada - - FEATURES -

A calo­rie is sim­ply a mea­sure of en­ergy (tech­ni­cally the amount of en­ergy needed to heat 1 kg of wa­ter by 1 C) that the body uses to drive chem­i­cal re­ac­tions. Clearly in a sys­tem as com­plex as the hu­man body it is a gross over­sim­pli­fi­ca­tion to as­sume that all calo­ries are equal no mat­ter what food they are de­rived from and that they all elicit iden­ti­cal meta­bolic re­sponses. This ne­glects the qual­ity of those calo­ries and, im­por­tantly, the hor­monal re­sponse they pro­voke in the body. Hor­mones are the pri­mary driver of not only body weight, but also body weight dis­tri­bu­tion.
