[QUOTE="Pneu, post: 322962, member: 28827"] I also low carb and use a pump so hopefully I can offer some insight although it can be a little hit and miss! Firstly the general rule of thumb I follow is that I need to cover protein at 60% of my carbohydrate ratio... i.e. if you would normally inject 1 unit for 10g carbs then 1 unit covers just under 17g of protein so (10 / .6 = 16.6....) So if you are eating quite high protein meals then you will still actually need a reasonable amount of insulin.. now this is where a pump is great because protein covert's quite a bit slower than carbohydrate to glucose.. so I would normal do say a 30/70% split on the bolus over 1 or even 1.5 hours depending on the fat content.. Now the tricky thing is that if you are still eating a reasonable amount of carbohydrate then it starts to get very messy as to when you need to cover for protein.. I have found that much more than 80g of carbs / day gives me real headaches as to when I need to cover for protein as sometimes I do and sometimes I don't... The good news I guess is on a sub 80g day my blood glucose will sit the WHOLE time between 3.8 - 4.6 mmol/l it hardly moves at all maybe + 1/2 mmol/l @ 1 hour post meal.. the problem is on those days where you are on the cusp and thus not sure what 'mode' your body is in.. Case in point was last night where I went out for a meal and had a pizza for the first time in ages.. I accepted that it was going to not be a good night on the BGs... it wasn't so terrible but this morning I went back to my normal eggs / bacon for breakfast covered the protein and then caught a hypo before it hit because my body had dropped out of ketosis back into carb mode! Meal had no carbs but my body also didn't covert the protein... so now I am going to spend today covering protein and testing to figure out when I jump back into ketosis! IMO it's best to be in 1 camp or the other.. either you are in ketosis 99% of the time (other than perhaps the odd treat) or your not.. being on the edge is not a fun place for glucose control.
