The minimum fasting duration generally recommended to start experiencing some health benefits is around 10-16 hours.
Understanding the Benefits of Fasting
The benefits of intermittent fasting typically begin when your body depletes its glycogen (stored glucose) reserves and starts utilizing fat for energy. This metabolic shift usually occurs after approximately 12 hours of fasting.
Key Benefits and Corresponding Fasting Durations:
| Benefit | Minimum Fasting Duration | Explanation |
|---|---|---|
| Ketone Production & Brain Health | 10-16 hours | As the body switches to burning fat for energy, ketones are produced. These fatty acids have been shown to potentially protect memory and learning. |
It's important to note that the optimal fasting duration can vary depending on individual factors such as age, activity level, and overall health. Consulting with a healthcare professional is always recommended before starting any new fasting regimen.
