Splitting novarapid for fatty meals?

Went to see the dietitian to ask about gaining alittle weight as im 6ft and 12stone and would like to put back on a half stone or even 1 stone...i look to skinny for my height. She said eat more calories and fatty foods. I know any fatty foods make the digestion of the food alot slower and effects my b/s by going low and then high later.

If i where to have a meal of about 80g carbs and which has about 20g fat in it. I have been told to split my dosage of insulin 4 shots with meal and then 4 shots after the meal.

Is there any particular time to take the remaining 4 shots? i.e. 1 hr after meal, 1.5hrs after meal or 2hrs after meal?

Also up to how much total fat in the food before I split the dose, i.e. split after 10g or more, 15g or more, 20g or more etc?

If any one could clear this up for me would be great.

She orginally told me to increase my carbs, so I did that for a few months and now change. My carb intake is this daily:

Morning = 60-80g carbs - 8-10 shots novarapid
Lunch equals = 80g carbs - 8 shots
Dinner equals = 80g carbs - 8 shots
Snack at 10pm = 20-40g carbs - 2-4 shots


I exercise between 4/5 times a week, be it 5 aside football a few nights or weights.

I tired splitting my dose last nigth, but after 1.5hr I check my bs and I was 10b/s, I gave myself the remaining shots and 2 hrs late i was 6.1. So it worked, just went a little high 1.5hrs after meal. Might give my self the remaining shots at 1hr after start of meal and see how i get on, I was just checking if there was any rule of thumb with spilting dose/fat content.

Plus its handy aswell, if not for weight gain, sometimes I just dont have time to make a healthy meal and now by spilting my dose gives me a bit of flexibility.
