Orthorexia and Disordered Fasting

Sustainable wellness cannot be built on shame. Orthorexia is disordered eating centered on purity and control, and fasting can become part of that pattern when driven by shame, obsession, or fear of failure. Aggressive fasting combined with a poor food relationship can become an eating disorder disguised as a wellness practice. Shame, obsession, and self-hatred do not create sustainable wellness, and a body cannot be healed through hatred or obsessive control. Orthorexia, disordered eating organized around healthy foods and practices, can incorporate fasting as a vehicle for obsession, shame, and punishment. When fasting becomes a source of stress and causes spiraling self-condemnation from minor deviations, it is counterproductive and harmful. The all-or-nothing framing in rigid online fasting communities — that a single deviation negates an entire fast — is clinically damaging. Rigid fasting purity rules, such as treating any deviation as failure, can contribute to orthorexic patterns. Managing orthorexia cases related to fasting requires collaboration between functional medicine practitioners and eating disorder specialists.
