I eat very low carb/keto and have been doing so for about 5months now really. I have seen it be absolutely brilliant for my control of my Type 1 Diabetes. My last A1C was 5.9%.
I was diagnosed last October after DKA which I thought was the flu at one point, and put on weight very quickly, going up to 181lbs (12st 13lbs) and just wasn't comfortable with that. I hadn't a lot of weight to lose, but I find it easier to lose and maintain weight eating this way. I am now 172lbs (12st 4lbs) and continuing to slowly lose weight, goal is probably 168-170lbs befor I go on holiday in 3 weeks, which would allow me to indulge a little more and be happy coming back under 175lbs.
Keep going with it and try to concentrate on how you feel more so than how the scales are reading. Perhaps taking measurements too, muscle weighs a little more than fat, so it could be that you are toning up too.
