A “dirty fast” is a fasting pattern that allows the consumption of low-calorie foods during the fast. This may be beneficial for those who want to try fasting but have certain health conditions or who have tried stricter fasting regimens and experienced difficulties. As some research has found fasting windows that allow for a few hundred to positive health impacts (5), many people are turning to “dirty fasting”.
Foods that are allowed on a dirty fast:
Non-starchy vegetables such as broccoli, celery, and cucumber
Bone broth
Small servings of low-calorie broth-based soups such as vegetable soup
Coffee or tea with cream or milk
Small servings of fresh fruit
1 tbsp unsalted nuts
