I don't think that a documented, reproducible very high blood sugar spike is nitpicking. I personally think it is reason for concern.
But you are absolutely correct, a sandwich is more than that. The author acknowledges this as well. It would be a fun thing to measure your blood glucose against (as I intend to). From an armchair perspective, the other ingredients in the sandwich may slow down the glucose dump into your bloodstream, but it will likely still dump the same amount, because the bread is still present. Along with the fat storage mechanism that glucose > insulin turns on, the extra ingredients may be more likely to be stored as fat.
I'll respond to this as soon as I complete the experiment!
Not sure if this comment is facetious or not, but Dr. Peter Attia switched to eating 5,100 cal/day ( http://www.youtube.com/watch?v=C3E0pFl370Y 11:19), mostly sat fat, and goes from 195 lbs (12:26) to 170, with the only weight lost being fat. Calories aren't calories.
What is this blog and why is it getting popular? The articles are very long and dense with no clear point.
"In some respects, there is nothing to be said; in other respects, there is much to be said" Please edit your blog posts to remove phrases like this which damage reading comprehension. Your opening sentence "Mathematical error has been rarely examined except as a possibility and motivating reason for research into formal methods" is long winded, vague, boring, and tells me nothing about what this post is about.
I think you can write much shorter, clearer articles that are not dense, rambling and inaccessible if you put some time into organization and structure and read your blog critically from a layman's perspective.
