Good to see people making an effort to improve their health.
It's hard work and takes discipline, but if you stick at it the results can be substantial. My catalyst came from weighing myself one Christmas and being slightly over 100kg, despite "carrying it well". Unfortunately playing/training football 5x a week equated to 5x days/evenings in the pub as well, so whilst I was relatively fit, I was putting on the pounds.
I eventually got out of playing football and took up Muay Thai, but even then it was at least a year before I started taking it seriously and really looked critically at my diet. Ended up getting down to 90kg for my first (exhibition) fight, then set a target at 84kg, and eventually bottomed out at 78kg for a pro fight (actually weighed in on the day at 77.3kg), and in a training trip to Thailand I reached 76kg but that's a different matter over there, with the climate, lifestyle, and sheer quantity of training.
Then turned my sights on Fell-racing which is my main passion now, far bigger in fact than football! Steadily built the race mileage up, 16, 19, 25, 33, 42, up to a 17.5 hour 45 mile race this summer. Going for a 102 mile race in Snowdonia early next summer. It's hard work and you have to be dedicated, but if you simultaneously get your training and diet together you can get massive results.
Spent most of the year hovering around 82-83kg but on a good spurt at the moment and just above 80kg. Which is large for a runner, although I am 6ft2" and considering my "fight weight" was 78kg, I'm not carrying too much extra!
