Hi
@jn81 - take a look at my signature figures - I am classified as T1-LADA as I am positive for all antibodies, but by going low carb, upping my exercise, (nothing extreme, 20 mins fast walking per day either after breakfast - preferable, or after lunch when working), my HbA1c has remained in non-diabetic range for the last 18 months and I do not take insulin (yet) - but I do see big spikes if I eat something of 'unknown origin', like Holiday Inn sausages, so I know it's not in my mind, or I've got better.
I was on 1000mg Metformin twice a day (2x2 tablets), and reduced to 2 x 500mg (1 tablet twice a day) about 4 months after diagnosis and it made absolutely no negative difference to my HbA1c, which I was really worried about too.
I went from c.80kg with lockdown boredom (previously 70kg and wanting to lose weight) and dropped to 60kg in 6 months before diagnosis, despite filling my face with all the worst foods, I am steadily 53kg now but was 48kg last summer, which was a bit too low. I eat c.100g carbs/day, but don't really check anymore - salad and 'meat' or crisp breads and peanut butter, blueberries and greek yogurt and variations of the same, boring but I know where I am without obsessing. 3 meals and a couple of little snacks a day.
Check out Jessie Inchauspé/Glucose Goddess - her explanations of the science and her hacks are my go-to.
Nuts, cheese and greek yogurt are your friend, and will keep the calories up but carbs down, and 90% Lindt chocolate, indulge, they are my go to snacks.
I am 53 now and was 51 at diagnosis for what it's worth.
I saw my consultant this week, and he still considers me one of his 'specials'; it appears that my T1 was triggered at the same time as my first covid jab, and it is, according to him, something that is becoming well documented - did your symptoms, with hindsight, start shortly after a jab, or another ailment? LADA is often 'virus' triggered, so I don't think the link with covid antibodies is too big a jump in how your body can react.
You can be T1 without antibodies, (or T2 with), it's not as nice and tidy as most would think.
I have been tested again for GAD and other antibodies this week, (as they had dropped a lot 12 months from my levels at diagnosis), and my c-peptide was re-tested for the first time too, (that's via a urine, not blood, test) - results will be a few weeks yet; but I am itching to know the results and any implications for my short/long-term future; my diabetes team can only suggest I keep doing what I'm doing until it doesn't work any more.
I'm sorry if this brain dump is a bit disjointed, I just wanted to show you are not alone in similar presentation and treatment options, and happy to share more of my experience if it helps.
