The summary of Wolpert 2012 is that for a 10gf low fat (LF) meal compared to a 60gf high fat (HF) meal, in T1 subjects, same gpr and gch, similar GI, crossover study, the high fat meals needed 50% more insulin per unit of carb, and were still showing higher BG than the low fat meals. So that's an acute effect in T1s, and a significant one.
Maybe what's happening is I'm going hypo when the fat wears off and my insulin:carb ratio reverts to normal.
Except I would expect the action of the fat to be 8-10 hours and the action of the insulin to be 4-5 hours so that doesn't make sense.
Maybe the ratio reducing action of the fat (in T1s) is much shorter, shorter than the action time of the insulin.
That would mean I go hypo shortly after I stop having butter coffees. That kind of matches... I'm going hypo a couple of hours after leaving the places where I am able to make butter coffees.
Edit:
I'm cross-posting (http://www.diabetes.co.uk/forum/threads/slim-and-save.74191/page-4#post-812367) with myself here, still a bit whacked from the hypo earlier today. But it looks like something - possibly the high fat diet, possibly not - has broken the magic IOB capability of my pump, which previously shielded me from the hazards of insulin stacking.
