Fasting for Health
Cutting off eating by 6:00 p.m. can significantly improve sleep quality, allowing for a 12-hour fasting period overnight. For optimal health, aim for a 14 to 16-hour fasting window most days, while being flexible and listening to your body's hunger cues. Various intermittent fasting methods, such as alternate day fasting, can aid in weight loss and promote beneficial metabolic processes like autophagy, especially when transitioning from a high-carb to a low-carb diet.In this clip
