1000 calories per day deficit (kcal for those using a sane system) is HARD. More power to him for pulling it off, but most people's bodies will fight them really badly with that kind of deficit. After two weeks on that kind of caloric deficit I get really angry and grouchy all the time. I have done it, but people around me definitely made comments when I went back to "normal" as to how much nicer I was.
