It's way easier to skip breakfast than dinner.

It works well for me because I'm not hungry first thing in the morning whereas I'm usually pretty hungry at the end of the day.

Many people have trouble sleeping on an empty stomach but not doing their work. Also night time is socializing time and there is no way that I would skip a supper with friends to fast but skipping breakfast is super easy to do.

Breakfast is relatively recent invention. It is simply against mother nature where we evolved as humans. Your body and brain need few hours of activity to feel hungry and find some food after night sleep.
