Neural circuits regulating activity-based anorexia - Nature
Eating Disorders (Google News) · April 7, 2026
In plain language
In certain mammals, combining a strict eating schedule with constant access to an exercise wheel can cause a dangerous condition called activity-based anorexia. Researchers are using new brain-mapping tools to study how specific neural circuits decide between eating and searching for food. Identifying these pathways helps experts understand why some individuals continue to exercise compulsively and restrict food even when their weight becomes life-threatening. These findings are important for developing future treatments for anorexia nervosa, which currently has no approved medications.

Key takeaways
- Activity-based anorexia involves a dangerous cycle of excessive exercise and reduced eating triggered by timed food access.
- Specific brain circuits in the hypothalamus and amygdala help animals decide whether to feed or forage for food.
- Compulsive exercise often persists in these cases despite extreme weight loss and internal physical damage.
- Research into these neural pathways is being used to find better treatments for human eating disorders.
- There are currently no FDA-approved medications for the pharmacological treatment of anorexia nervosa.
