Does intermittent fasting benefit the brain?
Intermittent fasting is a dietary approach aimed at weight management and health improvement, involving periods of calorie restriction followed by normal food intake. It has been suggested to offer benefits such as resetting metabolism, controlling chronic diseases, slowing aging, and improving overall health. Research indicates intermittent fasting may protect against neurodegenerative diseases like Alzheimer’s by providing the brain with an alternative energy source through ketosis, syncing eating patterns with the body’s circadian rhythms, improving mitochondrial function, and enhancing the gut-brain axis. However, evidence in humans is mixed, and there are potential risks such as nutrient deficiencies and decreased immune function, especially in older adults. It is recommended to seek advice from a health professional before starting intermittent fasting.
