Not really anymore. I used to be anorectic 10 years ago - naturally that involved being hardcore every day. The last time I lost weight, I went hardcore every day (by that I mean > 2 hours of exercising and eating 500 calories or so). This time around, my goal is moderation. I'm not terribly good at it, and my 30 minutes a day of exercise often turn into 70, but that's still a far shot off the pathological behavior I had before. I'm quite happy that I'm not counting calories at all anymore. But this time around, I treasure consistency and maintainability much much more over the intense stressed-out push-through mindset I had before. I'm reluctant to do anything now I wouldn't want to keep up as long as I'm alive.
I'm probably not representative though. So, if you can "go hardcore" without it impacting your mind negatively, please do! Reap the benefits, enjoy them. Just be aware of what you're doing, and things will fall into place.
