ABSTRACTIntermittent fasting (IF) is an eating pattern that alternates between periods of eating and fasting, offering a range of benefits that impact the body’s key systems. For the nervous system, IF enhances brain health by promoting the production of brain-derived neurotrophic factor (BDNF), improving cognitive function, and offering neuroprotection against diseases like Alzheimer's. It also reduces oxidative stress and inflammation, safeguarding neurons from damage. In the cardiovascular system, intermittent fasting helps lower blood pressure, reduce cholesterol and triglyceride levels, and decrease inflammation, all of which contribute to better heart health and a reduced risk of cardiovascular disease. From a metabolic perspective, IF improves insulin sensitivity, supports fat burning, and triggers autophagy, a vital process for cellular repair. It also boosts human growth hormone (HGH), which aids in muscle preservation and metabolic function. Regarding weight loss, intermittent fasting promotes fat loss, particularly visceral fat, by reducing overall calorie intake and enhancing fat oxidation. It also helps preserve lean muscle mass, making it a highly effective and sustainable approach for managing weight and improving overall health. In essence, intermittent fasting has a holistic effect, benefiting the nervous system, cardiovascular health, metabolism, and weight management, contributing to enhanced well-being and longevity.
