Do you use either ALO or HTP?

HTP basically meters an ISO step higher then applies a tone curve to compensate the image brightness. In other words, if the meter on standard settings would give you f/8 and 1/250 at ISO 100, HTP will meter f/8 and 1/500 at ISO 200 (or f/11 at 1/250, or any other equivalent combination depending on which mode you're in), then the camera processes the raw data at ISO 100 and lightens the image so the overall brightness is similar to the ISO 100 shot.

The way I see it, it's there to apply -1 step of exposure compensation (EC) for people who don't want to do that themselves. Guess what I'm gunna say next...

Yes, learn how to read your histogram and how to compensate the image brightness with the EC function. A lot of people think EC is a calibration setting (do it once and leave it alone forever), but it's a per-shot setting - take a shot, check the histogram and blinkies, change the image brightness if required and repeat until satisfied. Turn off all those "helper" functions (like ALO). Your camera will shoot faster and not get in the way when you're trying to take control.

As soon as you're ready, shoot raw and be amazed by what you can do.
