Update:  found this doc from nih.gov, http://archive.is/ooNxj Wonder why this isn't publicized far and wide?  Maybe it's all those food advertisers HuffPo et al don't want to upset, or maybe they don't want to upset the new fatfuck majority and commence the squeeeals about starvashun mode, fat-shame, etc.   I say both. EDIT:  Jesus & Buddha!  Just went back and read the amounts they are recommending What the actual FUCK:  Men 19–30 years    2,400–2,600 calories  And that's for not-actives...We're so fucked.
