Reducing carbs works much better for many of us. I am not a strict LCHF (which is 6g, 12g, 12g daily); I’m more like about 60g daily and have found my BG’s to be much better and my most recent a1c was 6 and I check my BG about 6x daily, usually between 80 to 120 with occasional 60’s and 130’s. If I eat more than 1 slice of pizza, no matter how I dose, it often results in over 150. So I minimize those occasions. For me, a pizza is not worth the trouble.
i used to do a LCHF diet, and i found that if i should have the occasional english muffin (or other high carb foods, like pizza) i needed to do a dual bolus just to handle the physical confusion for putting all the carbs into my bloodstream. but then i started needing carbs for my swimming, so i gradually increased my carbs, and now i no longer spike, nor do i need to dual bolus. i have no problem at all. and, i get to enjoy pizza and burgers with the buns. its been truly worthwhile to me !!! the only thing the LC did for me was to keep me very skinny. so, now i look physically fit AND, i get to eat things i enjoy.
