The concept is simple, a longer fasting time allows your body to “use up” circulating sugars more efficiently and transition into your fat stores as a last resort. Now, there is a bit more at play here on the cellular level and the liver, however I don’t want to bore you with too much science.
The golden fasting time is still widely debated, but most studies show anything in excess of 16 hours is ideal for most. To give you an idea, your liver is typically depleted of glucose completely (near 1% remaining) at around the 24-hour mark: (This isn't the goal, but am using it as a gauge).
I hope this helps, but encourage you to do your own research and talk to your doctor before trying as some medications can lose efficacy when fasting.

Good info above, thanks,
Maybe to due Covid and some other events? I’ve been often only eating one meal a day - dinner, and getting in some 10, 7 or 6 mile runs plus dumbbell workouts on days not running. The long periods of not eating for me are really helping me relax or focus. I’m weighting around 175 and should be closer to 160 when I’m in fighting shape. I want to start doing 24 hour fast. |
Sounds good. If you do try the 24 hours fasts, make sure you're eating enough in your feeding window.
I've found it's hard to get enough down for an 18 hour fast. That extra 6 hours is brutal.
Good luck and keep us posted.
