Tag: Fasting durations

Research indicates that fasting for as little as 12 to 14 hours can cause the body to switch from burning sugar to stored fat for energy, a process known as metabolic switching. The ideal duration for you depends on your specific health goals, from sustainable weight management to deep cellular repair.

While there's no single, scientifically-proven intermittent fasting chart based purely on age, anecdotal evidence and expert insights suggest that different stages of life may require varied approaches to fasting. A person's metabolic rate, activity level, and nutritional needs evolve over time, influencing the duration and method of fasting that may be safest and most effective.

According to nutrition experts, leaving at least 12 hours between meals can trigger the body to switch from burning glucose to stored fat for energy. Knowing how many hours without food is good for you, however, depends heavily on your individual health, goals, and lifestyle.
