Hi all. Today morning I woke up and forgot to not eat and broke my fast having eaten half a mandarine fruit. Now I’m courious how long would it take for my body to switch again to fasted state. Anyone knows?
If you’re getting really scientific about it, you can buy an over-the-counter glucose meter. This is what diabetics use, but you can use it as well to track your fasting state by checking your blood sugar levels. I believe it takes about 18 hours post eating to enter a state of ketosis. It can be accelerated through exercise and other factors, like how your body metabolizes food and sugar.
