If you were eating just veg then I would not stress much about going over when you use total rather than net. One of the reasons I like to use total is because I canāt be bothered to track but I can guesstimate pretty well after years on and off of counting calories and carbs and whatever so, by sticking with total I know I can get my numbers wrong but still be easily within net. So kind of a safety net of you like. Excuse the pun. Actually, that is pretty good - gonna run with that!
The things that I find make it easy to stack up a higher carb count are nuts and the sneaky carbs found in most cured meats and things like cheese and cream. I totally get the one of pizza and keto cookies and the like though so my advice would be simply to limit these and try and balance both in that day and the neighbouring days. So if you were over on one day because you had had pizza and loads of sneaky carbs and veg that all added up, just compensate the days before (if planned) and after.
There is no ONE way to do this and the most important thing of all is making it a WOE that you are happy with and so it is sustainable. Anyone can be in ādietā mode for a while but this is for life so you have to be happy with it and enjoy it.
