Investigating the effectiveness of an online telehealth dietitian intervention on food addiction in Australian adults

There are limited treatment options available for people who experience food addiction. This thesis begins by providing an overview of what food addiction is (including prevalence, overlap with co-morbidities and the influence of food addiction on dietary intake). Chapters 2 - 5 are presented as published studies which includes a systematic review of available treatment options for food addiction, followed by a co-design study involving people with lived overeating experience. Chapter 4 is a study examining if there are any proximal factors that may increase the risk of developing food addiction in a large dataset of Australian adolescents, and finally a study examining the effectiveness of a randomised controlled trial on improving addictive eating symptoms, diet, sleep and physical activity. The thesis finishes by providing a discussion regarding the implications for future research and practice.
