                                Research has shown that after 5-10 days of fasting, the plasma level of β-endorphin is significantly increased in human subjects. So, does fasting raise endorphins and influence your mood and well-being? The answer involves a complex interplay of hormones and metabolic changes that occur as the body switches its energy source from glucose to ketones during a fasted state.
