A few observations. First, everybody needs bolus, although under Dr. B you will likely find your basal/bolus ratio quite high, mine is 75/25. Dr. B actually "invented" the basal/bolus regime in 1972.
Second, you may need to bolus for protein and volume as much as for carbs. I eat lots of protein and have to bolus for half the protein as carbs. And if you eat volume, you need to bolus for that,even if your meal contains no carbs or protein (the Chinese restaurant effect)
I would not recommend one meal a day, that is too much time fasting. Although you may not feel hungry, it is probably better to eat a little something.
