Intermittent fasting (IF) isn’t just beneficial for weight management—it also supports brain health and neuroplasticity. Studies suggest that fasting promotes the production of brain-derived neurotrophic factor (BDNF), a protein that strengthens neural connections and enhances memory. IF can also help reduce brain fog and protect against neurodegenerative diseases by reducing inflammation and oxidative stress. Even a simple 12- to 16-hour fast (such as skipping breakfast and eating lunch as your first meal) can provide cognitive benefits over time.
