Hello
@jaijones_1997, I'm Type 3c (no pancreas) but my treatment is as if T1, plus some quirks.
Very early on I got Gary Scheiner's book "Think Like a Pancreas" and found that very useful as part of getting some understanding about insulin dependency. One of the things he covers is conversion of carbs, proteins and fats into blood glucose. All foods can get converted into glucose, but our bodies find the carbs easiest and so convert those first. Gary Scheiner suggests a 30gm 'rule', whereby if any main meal has more than 30gms of carbs then the body generally won't bother with converting proteins or fats. This seems to be supported by other specialists as well as people with D. This also is not difficult, since a low carb diet might be be anything below 130 gms daily, so 3 meals at 30gms is well short of that sort of level.
Generally carbs have a predictable conversion rate into glucose, for any one person and sometimes at different rates for the time of day - so one adds up the carbs, apply a conversion rate for that meal time and take a bolus accordingly. But proteins have different rates of conversion for different types, so the 'sums' get a bit more messy and the conversion into glucose takes a fair bit longer; so juggling timing needs even more consideration. Fats are worse for the sums and time juggling! So the 30gm carb rule keeps things simpler, without being at all excessive - unless you are intent on going keto with an ultra low carb diet, when the 30gm rule can't be used as guidance and glucose estimating becomes more hit and miss until you find how ultra low works for you. I favour keeping things simpler, whenever possible and I have a healthy appetite, with good cholesterol levels and a good BMI; so I eat what I want and take my insulin accordingly.
Gary Scheiner also says:
"
Diabetes is complicated, confusing and contradictory". I think that is so true. I don't try to control my D, the unpredictable moments make that a vain aspiration. But I do aspire to managing it, accepting that sometimes there are glitches; then see if there is a reason (so lesson to be learnt) and move on without over-analysing it all.
I also, after about a year, got Dr Ragnar Hanas' book "Type 1 Diabetes in children, adolescents and young adults"; the title misleads, its fine for 73 yr olds as well!
Arguably there is comprehensive information just within this forum and a book on D isn't really necessary. But authors tend to present their guidance in a structured format and sometimes it's easier to research within that structure. This forum is brilliant, a huge amount in here, but sometimes a search here is not successful because the exactly correct word isn't being asked; and also sometimes there is too much information within any one thread.
That's my hint to myself to stop rambling and wish you well.
