Providing alternative fuel for the brain in anorexia nervosa: a review of the literature on ketones and their effects on metabolism and the brain - Nature
Eating Disorders (Google News) · October 17, 2025
In plain language
Recent scientific research suggests that anorexia nervosa is not just a mental health condition but also involves significant metabolic factors. When the body faces starvation, it produces molecules called ketones as an alternative fuel source for the brain. This review explores how using these ketones, perhaps through specific diets or supplements, could help bridge the energy gap in the brain caused by severe calorie restriction. Understanding these metabolic changes may eventually lead to new treatments that support brain health and recovery beyond traditional weight restoration.

Key takeaways
- Anorexia nervosa is increasingly viewed as a combination of both psychiatric and metabolic factors.
- Ketones serve as a vital alternative energy source for the brain when glucose from food is unavailable.
- The brain uses about 20% of the body's energy at rest, making it highly sensitive to metabolic shifts.
- Women typically develop fasting ketosis more quickly than men due to differences in how their bodies process fats.
- Researchers are investigating if ketone supplements could help treat brain-based symptoms of eating disorders.
