Hi there Inka, congratulations, go you! Here is a link to the NHS BMI calculator which I use, simple and straightforward:-

I use the ‘myfitnesspal’ app to record all my measurements which I am now doing weekly, I weigh myself twice a week.
I agree that the range of ‘ideal’ weight is broad (no pun intended) and when I saw the range for me I thought that’s ridiculous. I was never the lowest weight in that range and wouldn’t want to be, now in my 50s I would look decidedly ‘scraggy’. So, I set myself a goal of losing a stone to bring my weight down to 9.5 stone, get my BMI to below 24, and being able to fit comfortably into my size 12s which over the last eighteen months got increasingly tighter and eventually pushed out of sight to the back of the wardrobe. I really hope when I get home in a couple of weeks that at least some of those clothes will now feel comfortable on me.
Good news on my own weigh in today, I’ve lost almost 2lbs, hurrah, broken the plateau stage it seems – I was a little anxious this morning before I got on the scales as if the weight had remained static for a second week I would have been right down in the dumps. My BMI is now 24 (dropped from 25 last week). So, onwards and downwards, half a stone to go.
