Hi - I would most definately recommend low carb to any type 1 for many reasons...
As said earlier - less margin for error with calculating insulin doses, therefore less hypos.
Great for weight loss - I have low carbed for almost a year now, although not overweight to start with I am a consistent weight now and have lost over 7lbs, I am bang on my BMI. With losing the weight I also take less insulin and apart from PMT I don't have huge issues with being insulin resistant. My consultant also praised me on my last hospital visit as i've bought my HbA1c down too and instead of seeing me twice a year I am back on annual visits.
I have the potential for less complications with type 1 for future years - fluctuating sugar levels can cause new nerves to grow and therefore potential for retinopathy issues etc.. Had an eye test done recently and no damage detected in my eyes (huge relief).
I don't suffer so much from depression or anxiety now due to stablised BG readings, before I went low carb and ate a normal diet I was constantly yo yo-ing causing me to get down alot, I am now more level headed, less blurry vision issues and don't feel so knackered in the afternoon.
I also believe by getting rid of pasta, sugar, wheat, bread etc, potatoes, rice that I much more healthier and have had people saying how much better I look.
Believe me going low carb isnt for everyone, it takes some getting used to, but the benefits certainly outweigh the negatives of being type 1, I still have the odd choc (but not the box !), a glass of red or 2, a spoon of rice with my curry and make some great pudding alternatives with agave nectar instead of sugar or banana bread with gluten free flour. I eat full fat cheese but not loads, I eat lots of cauliflower, leafy greens and salads, fish and protein and eating out I have a steak, salad and some chips so doesn't impact. Once you eat low carb you also lose sugar cravings and you are more aware of what you are eating so cook more fresh food and no processed, tinned stuff that are loaded with sugar.
My favourite saying is - Fat's my friend and sugar's my enemy !!
Dr Bernstein (type 1 doctor) recommends low carb in his book which is where I became inspired as I have a young daughter and want to live a long healthy life and this really is the only way I know how, I also feel so much more in control of my diabetes now and for me that really is a huge motivation to continue this way.
