The Effects of Intermittent Fasting on Brain and Cognitive Function

This review highlights the potential benefits of intermittent fasting (IF) on brain health and cognitive function. By promoting a metabolic switch from glucose to ketones, IF enhances stress resistance, cellular repair, and neuroplasticity while reducing inflammation and oxidative stress. Animal and human studies suggest IF may help prevent or slow neurodegenerative diseases like Alzheimer’s and improve mood and cognitive performance. IF also regulates circadian rhythms and enriches gut microbiota, further supporting brain health. However, more research is needed to confirm long-term effects in humans.

Consider intermittent fasting, such as the 16:8 method (16-hour fast, 8-hour eating window), to support brain health. Pair with a nutrient-rich diet for optimal benefits. As individual responses may vary, consult a healthcare provider before starting, particularly if managing health conditions.
