There's no level of carbs that is "good or bad", the real mantra is "eat to your meter" and try to get below 7.8 two hours after each meal. If you're currently always above that, you masy need a bit of a tweak to either type of carb or amount. Or, you may try what i do which is just ten minutes of hard'ish exercise about an hour after meals that give you typically these higher levels. just ten mins when BGs are peaking, typically at that one hour stage, seems to bring them down faster and lowwer for me. I reckon I get about 1 mmol lower like that. I use an exercise machine, but you could go up and down stairs as quick as you can for ten mins.
There are various different definitions I've seen of "low carb". On about 150 grams a day I'm "moderate", sites I've seen suggest lower than 70 is low carb, and lower than 30 is very low carb. Others have said lower than 50 is very low carb. I don't think you should bother; just get the right level for you and try the exercise
