Low carb the downfall of Krispy Kreme?

I was recently on an elevator that had a TV screen broadcasting the daily news and goings on in the world. One story, which caught my eye, was that Krispy Kreme donuts were blaming the low-carb diet fad on it slumping sales over the past few years.
Here’s my question….. On what diet are donuts included? Were these people not eating at Krispy Kreme because of the high carb-count? I bet if donuts had been low carb, people would have eaten there on the diet. Just like Subway had an Atkins wrap that included bacon!!!! Pseudo green.
