I have no reason to defend Kern or his views on being healthy. The point in question here is Lustig's physiology credentials. Kern isn't the first to bring them into question, and if Lustig's science isn't reliable, then why should I give him any credibility?

I avoided making any ad hominem arguments against a sugar-shunning overweight man who claims sugar causes obesity, or a doctor writing about sugar who can't distinguish between sugar and starch. My mother told me 20 years ago not to pound soda, so why is Lustig relevant?

Yes, I believe that junk food is bad, and sugar is a big part of it. The landscape of obesity is far more complex, however, as Lustig himself helps to show (he mentions his tight schedule and lack of will power as reasons for eating two meals of junk per day). I really don't feel that making sugar the new fat changes anything at all.
