Tag: Why do i have more energy when i haven t eaten

According to Johns Hopkins neuroscientist Mark Mattson, our bodies evolved to function optimally during periods without food, a state that triggers powerful metabolic changes. This ancestral adaptation helps explain the seemingly counterintuitive phenomenon of why do I have more energy when I haven't eaten. The feeling is often due to a profound metabolic shift, reduced digestive load, and a cascade of hormonal adjustments that sharpen focus and increase vitality.
