The role of intermittent fasting in brain health

This review highlights the potential benefits of intermittent fasting (IF) for brain health. IF reduces neuroinflammation, decreases insulin resistance, and enhances autophagy (cellular cleaning processes), all of which are linked to improved cognitive resilience and aging. Key mechanisms include the metabolic switch from glucose to ketones, which activates anti-inflammatory pathways and promotes brain repair. The findings emphasize IF's promise in protecting against neurodegenerative diseases like Alzheimer’s, though long-term effects and variations between IF regimens require further study.

Adopt an intermittent fasting method, such as alternate-day fasting or time-restricted feeding, to support brain health. Pair fasting with regular exercise and a nutrient-rich diet for optimal results. Consult a healthcare provider before starting IF, as individual needs and health conditions vary.
