Who wrote the piece of information you quoted? What are his/her credentials? What studies have been cited as support for these claims? What is the evidence for the author's assertions?

I teach first year university English. My aim is to teach my students to write essays that present a balanced, thoughtful argument, quoting reputable authorities and presenting a critical analysis in order to persuade the reader of the validity of their claims.

If one of my students handed in the article you've just posted, they'd get a failing grade. No evidence whatsoever is presented in support of the argument. Why should I believe a word of it?

If you're looking for evidence to show your wife that low-carbing is safe, there are lots of studies posted on this site. Click "Studies" on the red bar on top of this page.
