Hi there - I'm a bit late to the game, as I didn't see this posting until today.
For what it's worth, I eat six mini-meals per day. Each meal is between 200 and 300 calories, and I end up with around 1500-1600 / day. I also try to balance carbs / fats / protein within each (no easy task, that, lol) so I average 50% / 20% / 30% or thereabouts. I still need to lose about a stone to be in an average BMI range, but I'm getting there slowly but surely. I try to be sparing with the test strips, so I don't test before / after meals unless there's something unusual going on (a special dinner, or planning to eat out, holidays, etc), but my morning pre-breakfast BGs are usually something like 4.8, 5.0, in that region. So far, so good!
