I think it's about 150g's on a high carb day, I don't do a daily allowance, just count what I'm eating for a meal or snack to adjust my insulin..
I don't buy into the low fat this high what ever that dogma's just a little of everything is good for you to much of one is bad theology with fresh and scratch cooked is far healthier than processed..
So I'm just as likely to have a fry-up, pasta (home made pasta) roastie or a nice omelet or cauliflower cheese on my plate, the only thing I would say isn't standard is bread, not keen on sandwiches so don't often eat bread.
Control wise, I've just checked my data, which is showing an average of 5.4mmol/l, SD 1mmol/ charts are showing, 89% in range, 4% hypo 7% above range, but highest reading is 7.2mmol/l
I do use a pump, because I'm pretty sensitive to insulin and have a basal profile that can't be tamed by 2 background injections a day..
As to extreme low carbing more beneficial for T1's is there a more of a up take and does it reduce medication...
I wouldn't say that there is a increase of T1's going extreme low carb, as in truth it's actually works along the lines of any Fad diet, it comes and goes just the same as Atkins, the cabbage diet the F-plan diet etc etc.. very few turn it into a long term lifestyle.. And the handful that I know have are mainly T2 diabetics, and the T1 funny enough take a lot more medication than I do, even the insulin is a lot higher than mine.. And so far none have achieved their weight goals long term..
I think I rather do as I do, I don't crave anything nor fall of the wagon, because if I want it I can have it and still maintain the control I desire.. without much hassle
