Split bolus's

Never had to split-dose for crisps.

I'm not sure at what point you have split-dose for high-fat meals as I never really count the fat & protein content in a meal and just concentrate on the carbs, however I know from experience (trial & error) that certain meals do need more insulin than others and a split-dose bolus is required, the best thing to do is take note which meals do require extended boluses and keep a record of them for future reference.

I don't split for a high fat meal just put on a temp basal of +30% at 2 AM to last 4 hours and that solves the problem. When talking about high fat I mean fish and chips which is a rare treat. Crisps I don't eat as don't snack between meals.

unfortunately like most things diabetes, its all about trial and error.........

I have always though and I am sure many will agree, that PIZZA is a perfect example where a split dose would help.........

so that might be a good place to go to see what the fat level actually is for a pizza, you can then use that as a reference point.....

Split bolus for a meal that is high in fat does make sense. As does the alternative of a TBR for those who have a pump. I agree though that the threshold is quite a high fat %. Pizza or proper fish and chips, not just crisps.

Pizza is the killer for me, still haven't managed to maintain any sort of decent control for at least 12 hrs after eating them...
