Mifflin-St Jeor equations used to determine calorie average daily metabolic rate. According to the majority of scientific data this is the moste accurate of common predictors of metabolic rate.
there are numerous equations used by fitness professionals, nutritionists and medical personnel
indirect calorimetry generally not as utilized - expensive device, inconvenient, tedious prepartation to ensure accurate measurements
here is a link to the Mifflin-st jeor method http://www.scientificpsychic.com/health/cron1.html
i am assuming TEF is considered in developing this equation , although generally rather low 8-15%
i often cross compare methods and generally they are very similar
