abstract = {The aetiology of anorexia nervosa (AN) presents a puzzle for researchers. Recent research
has sought to understand the behavioural and neural mechanisms of these patients’ persistent choice
of calorie restriction. This scoping review aims to map the literature on the contribution of habitbased
learning to food restriction in AN. PRISMA-ScR guidelines were adopted. The search strategy
was applied to seven databases and to grey literature. A total of 35 studies were included in this
review. The results indicate that the habit-based learning model has gained substantial attention
in current research, employing neuroimaging methods, scales, and behavioural techniques. Food
choices were strongly associated with dorsal striatum activity, and habitual food restriction based
on the self-report restriction index was associated with clinical impairment in people chronically ill
with restricting AN. High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) and
Regulating Emotions and Changing Habits (REaCH) have emerged as potential treatments. Future
research should employ longitudinal studies to investigate the time required for habit-based learning
and analyse how developmental status, such as adolescence, influences the role of habits in the
progression and severity of diet-related illnesses. Ultimately, seeking effective strategies to modify
persistent dietary restrictions controlled by habits remains essential.},
