Cheers bud! I round up to 5'10" and 150 lbs, test and balance technician, maintance for the height hovers about 2000 kcal on average.  And Ill vouch my resting rate is a little short of 2k calories.  Been homeless, had periods of not eating, and I am constantly climbing ladders, trusses, crawling in attics or above drop ceilings (fucking hate metal studded structures), i have no problems even when i was a tin banger going through an entire day without eating.    Eatbeasts only ever think of the calories in and a "slow metabolism" never that pesky calories out part.
