Deep dives
Understanding Intermittent Fasting
Intermittent fasting involves alternating periods of eating and fasting, which can be adapted to fit individual lifestyles. The concept is less about the fear of going without food and more about managing the timing of meals to extend fasting periods. Common methods include time-restricted eating, where meals are consumed within a specific window, typically spanning from six to ten hours. This practice contrasts with older approaches like the 5-2 method, which allowed for some caloric intake on fasting days but is now seen as less effective.
