When do you start your fast?

I usually start my fasts 3-4 hours after I'm done eating, because that's when the body goes into fasting mode.But, many people start their fast immediately after they're done eatingWhat do you do? Which is better? Does it really matter? via /r/intermittentfasting https://ift.tt/0B1h7vf https://ift.tt/bBwyqmW
