From the article:

Where an energy (calorie) deficit was achieved by food restriction, participants showed increased levels of the hunger hormone ghrelin and lower levels of a hunger suppressing hormone peptide YY. They also ate almost a third more at a buffet meal compared with another occasion when the same energy deficit was created via exercise (participants ate an average 944 calories following food restriction compared to 660 calories after exercise).
