Jag1, I realize you haven't watched the video, but in the video as well as her blog Franziska says she herself blood sugar issues, although she has a normal fasting blood sugar, she can spike as high as 200 after a carby meal. High carb meals can also produce a reactive hypoglycemic reaction. I don't know how that would be diagnosed.
In my view her approach is more pragmatic than dogmatic. She gradually reduced her carb intake over several years until she could meet her blood sugar goals(keeping < 140 postprandial). To me the point to the blog post you referenced is that she is able to achieve normal blood sugar numbers by restricting her carbs to a very low level and that at the same time she still feels good and her brain is still functioning despite the predictions of the RD mainstream.
In a society that is as lawsuit happy as ours, I consider the disclaimer at the bottom of every page to be more prudent than cop out.
In the blog post you referenced the last sentence is
"Carb restriction may not be appropriate in every case, but I defy anyone to objectively look at the evidence and deny how beneficial it's been for so many, especially those who have struggled with weight and blood sugar issues for years."
In the video, which again I realize you have not seen, she is supportive of whatever level of carb consumption a person uses to meet their blood sugar goals.
I don't know how her previous profession as a court reporter has any bearing on the quality of her dietetic advice. She went to school and passed the tests so she has the right to put the letters after her name. Her blog posts are well researched and footnoted. By your reasoning the fact that I was a carpenter in a past life and know how to cut the rafters for a complex roof somehow means that in my present job in IT I am somehow not qualified to write a complex SQL statement.
I think tuD works best when we speak from personal experience instead of a dogmatic position. Readers can then be exposed to a wide range of views and experience and decide on a path forward. My experience as a T2 not on insulin who has found 30 to 50 grams per day to be essential to meeting my blood sugar goals, in no way negates your experience as a T1 who is able to meet his goals at a higher rate of carb consumption. But the fact that your level of carb consumption wouldn't work for me, or Franziska, and in fact would be a blood sugar disaster, doesn't make either of us a "nut job", just different and determined to meet our condition head on.
In my view diabetics who set ambitious goals and then do whatever it takes to meet those goals should be respected not attacked.
