The effect of four-week intermittent fasting from dawn to sunset on circulating brain-derived neurotrophic factor levels in subjects with metabolic syndrome and healthy subjects

摘要

Brain-derived neurotrophic factor (BDNF) is a key neurotrophin that regulates food intake and energy hemostasis. BDNF also promotes neurogenesis, neuroplasticity, and neuroprotection. There are conflicting reports regarding how intermittent fasting affects circulating BDNF levels. We tested the hypothesis that 4-week intermittent fasting from dawn to sunset (4-week-IF) would decrease circulating BDNF levels in subjects with metabolic syndrome and healthy subjects.
