Is this new in your world? If so, take it in stride. It will become "old" and no longer be a thing.
In my world I'm 20 yrs in as a chronic patient and 10 yrs with a full dx! NOBODY asks me any more. Friends, family -- they all asked back there when it was novel. Now for the last 10 yrs since the full dx... they all know, so there's no need to ask! I have times where I'm close to goal weight and times where I regain. I'm always adapting to meds and situations and get endoc checks every 3-4 mos. This is my life.
I use a mixture of techniques -- calorie counting & diabetic exchanges are my main. It's work, but not struggle. I have lost a lot before but regained. I have not mastered "maintaining" yet. So I have to pass thru "losing" again before taking another stab at it.
Friends and family check in with me to go "Hey, at the party... can we get you anything special?" and usually it is "No, not really." There's 2 other diabetics so there's enough "safe" food for me around and I BYO too. Nobody bats an eye.
In the early days when I was still learning and so were they it was annoying. But I know it was because this was "new."
For strangers? I don't explain the whole PCOS/IR/hypothyroid thing. I just keep it simple with "I'm prediabetic. I get in exercise and do a diabetic diet" and since most people know the name "Type II Diabetes" they go "Oh" and let it go because it is boring.
Before I had my dx I'd lie. "Oh, doc told me to watch cholesterol." and they'd go "Oh" and let it go. But seriously... what doc DOESN'T tell you to watch cholesterol?! LOL.
I'm pretty open here on the forums but in real life I really don't want to get into my health biz with people. It isn't their biz!
