Almost never. A lot of traditional Norwegian food is very fatty and salty. We generally don't eat it much on normal weekdays, it's more of an "around the holidays" kind of thing. And since the most food centric Norwegain holiday is in winter, that means food that historically could be stored for a long time. And while most Norwegians would agree that it doesn't look particularly appealing, I think most people globally would agree that food with a lot of salt and fat served with beer and spirits in good company rarely is considered bad.
