Hiya, I'm 37 and close to your weight, was 212 but currently 209. The heaviest I've ever been was about 216 - but I'm very short. So probably comparable BMIs and I teetered very close to morbid obesity. I am also counting calories as well, and I'm on day four of my approach where I actually planned every breakfast, lunch, and dinner for the whole week. It's a very low calorie diet at 1200 calories. I'm a frequent binger, delivery orderer, and restaurant goer. I wish you well on your path. I think I need to be about 150 or 160 to not technically be obese but overweight so I have a long way to go for a big milestone.
Though slow weight loss is definitely the best approach I'm trying to train my belly to get used to a low cal diet because I did see in a documentary that once you've been obese you have to eat less than someone who never has just to maintain the same weight. Becoming obese really does permanent damage, not just to your skin.

I tried an 1800 calorie diet before but I kept binging on it and the weight loss was too slow so I gave up. But four pounds in a month is 48 pounds in a year, not bad at all.
