Here we present a protocol to induce activity-based anorexia (ABA) in female adolescent mice. ABA is a condition of hyperactivity evoked by imposing food restriction on rodents with access to a running wheel. This phenomenon is being used as a model to study the underlying neurobiology of anorexia nervosa.

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses. Symptoms and Physical Effects Individuals with anorexia nervosa commonly exhibit extreme...

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Assessing Activity-based Anorexia in Mice

Mice individually housed with a running wheel while given limited access to food develop reductions in food consumption and increase activity on the running wheel. This experimental phenomenon is called activity-based anorexia. This paradigm provides an experimental tool for studying the neurobiology and behaviors underlying aspects of anorexia nervosa.

Here, we present a systematic approach for developing physiologically relevant, sensitive and specific in vivo assays for interpreting variation in human pathology. Transient genetic manipulation via microinjection of WT and mutant human mRNA and morpholino (MO) antisense oligonucleotides harness the tractability of the developing zebrafish embryo to rapidly assay pathogenic mutations, especially, but not exclusively, in the context of human developmental disorders.
FAQs
The paradigm links two controlled influences: restricted food access and voluntary exercise. Their combination can shift energy balance toward reduced intake and weight loss while activity increases. This relationship helps researchers examine how feeding behavior and physical activity may reinforce one another under conditions of energy deficit, rather than studying either behavior in isolation.
An anorexia nervosa model can support focused studies of feeding regulation, stress responses, and neurobiology alongside observable behaviors such as food intake, activity, and changes in body weight. Examining these features together allows investigators to relate measurable behavioral outcomes to physiological processes and to evaluate how energy balance may influence the system under study.
Energy balance provides a framework for examining how food availability, intake, activity, and weight change interact. In the activity-based paradigm, reduced access to food occurs alongside voluntary exercise, making it possible to study the behavioral and physiological consequences of insufficient energy availability. This focus connects measurable changes in behavior with broader feeding and stress-related mechanisms.
A basic setup combines limited food access with an opportunity for voluntary exercise under controlled experimental conditions. Researchers then monitor outcomes such as food intake, body weight, and activity. Keeping these influences and measurements defined allows the study to examine how their interaction produces selected behavioral and physiological features relevant to anorexia nervosa research.
Key outcomes include reduced food intake, weight loss, and excessive activity, which are behavioral or physiological features that can be measured within the experimental system. These observations help researchers assess how the model responds to altered food access and exercise opportunities, while also providing a basis for investigating feeding regulation, stress responses, and neurobiology.
Findings should be treated as evidence about selected features rather than a complete representation of anorexia nervosa. The model can inform research on behavior, physiology, feeding regulation, stress, neurobiology, and potential treatments, but interpretation should be combined with clinical, psychological, and social research. This broader comparison helps evaluate disease mechanisms and translational relevance.
