Unintended weight loss

Just wondering if anyone can help me shed light on this. I should start by saying I have spoken to my doctor and she isn't concerned about it.
I joined MyFitnesspal about 5 years ago as I was underweight and needed to gain. Managed to get up to around 58 kgs which felt and looked right for me. I wad able to pretty much maintain that weight for nearly 5 years. Then last year I was diagnosed as Pre-diabetic. The advice was to cut down on carbs and sugar,which I did.
Here's the thing. I'm taking in the same amount of calories that I was before. I've adjusted fats and protein to make up for calories lost due to fewer carbs. My activity levels are the same. Yet I have lost around 5-6 kgs in the space of 6 months. I've now upped my calories and have stopped losing but still can't seem to regain what I've lost. I'd be grateful for any tips! Tia

    6kg over 6 months would indicate a deficit of around 250 calories a day. That's quite a large difference if you were maintaining before, but our bodies aren't mathematical equations, so there might be reasons for it.
    For example, protein takes a bit more work (=calories) to process.

    By how much have you increased your intake? You might just need to increase some more to gain back the lost weight.

    Thank you, I'm pretty sure I haven't been in a deficit but as you say,it's not an exact thing.
    Normally I maintain on around 2300. I've increased to 2500. I'm not a big eater and suspect I'd struggle to eat more!

    If you're gradually losing weight over an extended period of time, you're almost certainly eating at a deficit. No way to know whether that's because you're burning more calories for some subtle reason**, or not absorbing calories from your food as thoroughly as previously, but if stored fat is being depleted, you're in a deficit.

    ** Just "spontaneous movement" - things like subtle fidgeting - can burn in the low hundreds of calories per day, according to research.

    A so-called calorie calculator actually only gives you an estimate, and reality for any given individual can differ from that estimate at any given time. A fitness tracker is also giving an estimate, just a more nuanced one. Even one's own past experience can potentially be a misleading guide, even though it's probably the best source of estimates. Some people find that after they've been maintaining for a while, their calorie needs go up (because they have a little more energy that gets expressed in various ways).

    As long as blood tests, etc., aren't showing signs of any (any more) health conditions of concern, then eating a bit more is going to be the best strategy, I think. If you're already feeling full, consider foods that are calorie dense, but not very filling, such as beverages, fats, or fat-dense foods (nuts, nut butters, seeds, condiments like mayo or full-fat salad dressings), etc.

    Thank you. I am actually a fidgiter and rarely sit still but have always been that way. Thinking about it,I've been walking a lot more (in an attempt to lower my blood sugar)so maybe it's that. Thanks for the tips :)

    You said your activity level was the same in your opening post so I didn't mention that possibility, but yeah, that's definitely a possible cause 🙂

    Yes, that would mean your activity level is actually not the same as it has been...you've increased activity.

    I know, I'm daft. It wasn't until I thought about it that I realised how much more walking I've been doing. I wear a fitbit and assumed the adjustment of calories was accurate so although I've eaten back the calories given, it's possible that it's not enough.
