I'm currently just under 6'5" with a weight of around 280. When I was a senior in high school, I think my lowest was down around 180, which at that point I was pretty skinny for a tall guy. A couple years later I met my future wife, I was probably around 195.
We moved in together 2-3 years after that, and that's when my weight gain really started. The first problem was that I had just started a new job which was right next door to a gas station. I worked there for almost 4 years, and looking back on it now, pretty much every day I was walking next door and getting a 32 oz. fountain drink and a hot dog or two, sometimes some candy of some sort. Plus, my now live-in girlfriend was fixing dinner every night, something my bachelor self rarely did. I always ate a big lunch and that was pretty much my food for the day. Even if I ate 2k calories at lunch, that was all that I would eat. Now I was adding dinner and all this soda and junk on top of it.
I ballooned up towards 250 around when we got married. Now 4 years later, I've hit 280. That was a month ago. I'm at a job currently where I sit 8 hours a day, and I do nothing when I get home. I still play basketball when it's warm, but not enough to make a difference. About a month ago after finishing up a basketball league here at work, I was pretty mad at myself for being so tired and soaked in sweat after just 10 minutes on the court every game. So for the past month, I've been going to a local church that has some equipment and I've been running/walking on a treadmill at least twice a week. I've also been trying to cut down on eating out for breakfast and lunch and making healthier choices all around. Honestly, that's a work in process.
In my month of somewhat getting better, I've dropped about 4 or 5 pounds, which isn't much, but I'm trying (still have some mental work to do). Another basketball league starts up here in about 3 weeks, which I will combine with my treadmill running. It'll also be warm out, so I'll be playing basketball even more at the park.
I don't currently have any kind of weight goal, but I know what I need to do, and I feel like I'm slowly getting there. If I could get down to 260 by the end of June, I'd be ecstatic. We'll see how it goes.
