good I am also 5ft 10. With plenty to lose! I am approaching the weight you were at the start, having lost 2.6 stones this year.
I have lost 13lbs in the last month by eating 1340 ish daily. I am now on 1280. It is hard maintaining this low calorie intake no doubt about it.
I am very sedentary due to current health issues, so not burning anything off. Honestly I could eat 1200 cals in half an hour!
It's funny how everyone is at different stages. I can clearly remember where I was working when I weighed 15 stone odds, I had just started a new job and was wearing size 16 trousers and size 14 tops. I looked ok! Wish I could close my eyes and be 15 stone again! I should have got a hold of it then, but for various reasons my weight spiralled ever upwards.
Of course I am not saying 15 stone is an ideal weight, it still has health consequences which is my number 1 priority now. But if you are 5 ft 10 and 15 stone, most people would never guess you are that weight. Unless they too were 5ft 10 and 15 stone, you get the picture!
I have always loved being tall, but in terms of maintaining a healthy weight it has done me no favours. Because I could "get away with it" for longer I let my weight drift upwards.
Ah well, I am feeling reflective tonight, sorry for the monologue. I am doing something now, which is the main thing.
Good luck to you all on your weight loss journeys.
