+1 on the ‘everything in moderation’ approach.
I think the DAFNE promise of ‘eat whatever you like and just shoot for is’ is unrealistic. Similarly, extremely low carb would drive me (and my family) mental as it is quite difficult to manage in many social situations. Added to that very low carbers seem to find that their body becomes increasingly adept at converting protein and fat to glucose, but since this conversion takes much longer it can make the use of current ‘rapid’ insulins a bit tricky without some fancy dose splitting as the insulin might be acting more quickly than the food.
I guess I average about 130-160g a day. I’d agree with Bernstein’s general idea of ‘smaller doses, smaller mistakes’, but will also quite happily have an entire day’s worth of carbs in a chip shop blowout from time to time. On the whole though (perhaps because of the advice I was given at diagnosis all those years ago) I fare best sticking to fairly consistent, fairly moderate carb.
