Does dieting make you fat? A twin study

Authors:Pietiläinen, K. H., Saarni, S. E., Kaprio, J. and Rissanen, A.
"Our results suggest that frequent IWLs [intentional weight loss] reflect susceptibility to weight gain, rendering dieters prone to future weight gain. The results from the MZ [monozygotic] pairs discordant for IWLs suggest that dieting itself may induce a small subsequent weight gain, independent of genetic factors.
