Obesity is recognised as a multidetermined issue. However, research aimed at addressing diet failure has typically examined factors in isolation. Furthermore, previous research has included limited input from dieters themselves. A qualitative study identified a number of themes contributing to diet failure. This study aimed to test these themes with a larger sample ( n = 426) while also determining their fit within a multifactorial model. The results of this study supported the conceptualisation of diet failure using a multifactorial model while also illustrating correlational pathways to be more complex than currently understood in the literature.
