Being chinese and growing up in a chinese takeaway, not that I ate off the menu everyday, I think it depends on what it is. For example: if it’s chinese food the savoury kind - stir fry veg and plain rice, I don’t split dose it. If it’s pancake rolls, sweet and sour veg, whatever fried extras, I tend to do 50/60% up front and do the remaining after 30mins. For pizza, I’m still working on that but so far 50% up front and remaining 50% after 30 mins could go either way for my blood sugar. Nandos, McDonalds and TGI fridays I have no issues with because I’m only tackling chips or wrap or a burger bun for carbs.
