I'm with on wanting to stop losing weight.. I did plateau off in the autumn, less exercise, stop testing and weight stabilised at 75 kg, which as I am 1.8m tall okay.
Spring comes, more walks, started testing (numbers okay).... weight down to 72kg and not so keen with this.
BG are lower, which is good but my carbs are always less than 50 g a day more often way lower...
I going high fat / calorie route at the moment, avocado central and loads of olive oil is me... and weigh myself on Monday, every two weeks... so time will tell if it is working...
I is aT2 with no meds, I'm sorry I'm not sure I know much about T1s.
