how do you work out what to bolus for your protein based meal. I'm really struggling with omelettes and a bit of bacon in the mornings. I'm having to guess, i've kind of got it down to 2 units now which semi seems to work. Same with Chicken on it's own I think I need about 1.5 units but it's so hard to determine.
I'm going to distinguish between bolus for meals and bolus for protein. When I bolus for low carb meals, it doesn't matter what's in it meat/veg/cheese/eggs - I will need to bolus for how full I am, or judge the volume of food based on previous experiance. I'm careful not to eat too much protein as it causes a spike around 2-3 hours after eating as it's converted into glucose by my liver. I go by the rule that a chicken breast sized protion of meat requires 1 unit of insulin 2 hours after eating.
For example, when I have a chicken breast with salad for lunch my 2-hour-after-eating level may be consistent with the before meal reading, but my before dinner reading will be 2 mmol/l higher. For me that is what one unit of insulin will reduce my levels by, so I give myself one unit of insulin 2 hours after lunch. Anything smaller than a chicken breast doesn't affect the spike I get from protein.
I tend to stick to smaller portions as I don't want to be pumping myself full of insulin. Because for me the escence of low carbing is that small amounts of insulin leads to smaller mistakes, both high and low.
