By promoting autophagy, a cellular process that removes damaged cells and proteins, fasting can help improve cellular health and longevity. Fasting has also been shown to increase the production of growth hormone, which can help improve muscle mass and skin health. In addition to weight loss and anti-aging benefits, fasting has also been shown to have positive effects on mental clarity and cognitive function. By reducing inflammation and oxidative stress, fasting can help improve brain health and cognitive function. Fasting has been shown to increase the production of brain-derived neurotrophic factor (BDNF), a protein that plays a key role in brain health, and improve mood and focus.
