I agree with Coach Jen - this is really only a concern if you are creating a very large calorie deficit on a routine basis. Take your hike as a nice bonus, and don't use it as an excuse to undo your hard work.
I disagree with Zorbs - 2500 does sound a little high, even at 284 lbs. A figure of around 150-200 calories per mile is typical when hiking (probably at the upper end for you), which would suggest around 1600 calories.
An alternative check is that it takes a very fit person working extremely hard to burn 800 calories per hour, and figures above this should be viewed with skepticism. And for something sustained for 3 hours would probably only be 600 calories per hour.
So probably a figure of 1500-2000 is more realistic (and that's still pretty darned impressive).
If you're consistently undereating (for months and months), your metabolism will likely slow down to compensate for it. But this isn't something that happens in one day or one week- it's a much longer process. If this activity is not part of your regular routine, I'd just listen to your body and eat a little more if you feel like you need it. I'd only adjust your program settings if this is a regular activity.
Hope that helps,

make sure you change your fitness goals to accurately reflect the amount of exercise you're doing.
2500 at your weight for hiking sounds about right actually.

So according to sparkpeople, my 8 mile 3 hour cross country hike burned about 2500 calories. I have a hard time believing that, but it's what it says. I don't do that very often (in fact making it to the top of the small mountain I hiked was a serious pride point for me and a bucket list checkmark) but I wanted to know...that's more than spark even recommends I eat in a day. I also hit my fitness goal for the week in one run. My question is how should I adjust my calories for today/tomorrow to compensate so I don't go into starvation mode? I had some healthy snacks and some not so healthy ones, but I've been eating on the bottom rung of my calorie range for the most part. I ate a little closer to the upper limit today, but again the number shock is setting in. Any suggestions guys?
