Listen in today for why actually avoiding food is one way to help your digestion!. Short term fasting is one way to allow the digestive system a well deserved rest. There are many types of fasting. Intermittent fasting is where you take in no calories for 16-18 hours in a row. An example is you ear dinner before 7 pm and no food after that. Your next meal would be lunch around noon the next day. Make sure to drink plenty of water that morning though.
You can also try a 24 hour water fast. Nothing but water for 24 hours. If that is too tough you can drink water and green juices and bone broth. If it is still too hard you can add a mid day leafy green salad - but just greens with a splash of vinegar
Plan your fasting for a day when you will not be doing lots of hard physical work and can take plenty of rest.
