Ultra Beginner Advice

John Medinger, publisher of Ultrarunning magazine and highly experienced ultrarunner himself, offers some splendid suggestions for those starting out in the sport in "A Primer for the Beginning Ultra Runner" (March 2011 issue). In brief, as Medinger's subtitle says, "Keep It Simple":

My only point of skepticism: the suggestion that a particular product that claims to be "a naturally-occurring amino acid complex" actually "enhances your body's ability to metabolize fat" and can "cut your caloric needs by about half". There are plenty of anecdotal endorsements, but is this medically verified? I need to see some real, controlled studies (and a biochemical explanation) before I can begin to believe. (cf. Medicine and Statistics)
