Well, what the article says about the “what the hell” is that it’s one of the impulsive options we take when we’re fatigued with decision-making. The other option is doing nothing. Both can be troublesome – the latter because not doing something can lead to bigger problems down the road (like not opening bills to pay them on time).
So based on this article, a little boost of glucose later in the day when I’m fatigued but still have decisions to make can help. But I’d still like to have ice cream for breakfast!
