While fasting for autophagy, it's important to avoid consuming any food or drink that contains calories or carbohydrates, as this can break the fast and inhibit autophagy. However, certain teas can be consumed during fasting, as they do not contain any calories or carbohydrates. Here are a few examples:
Black tea: Black tea is a type of tea that is made from fermented tea leaves. It contains caffeine, which can help to suppress appetite and boost metabolism.
Green tea: Green tea is a type of tea that is made from unfermented tea leaves. It contains antioxidants called catechins, which have been shown to improve insulin sensitivity and promote autophagy.
Herbal tea: Herbal teas are made from a variety of plants and do not contain any caffeine. Some herbal teas, such as chamomile or peppermint, may help to suppress appetite and promote relaxation.
It's important to note that some teas, such as fruit teas or flavored teas, may contain calories or carbohydrates and should be avoided during fasting. Additionally, while tea can be a useful tool during fasting, it's important to drink plenty of water as well to stay hydrated and support the body's natural detoxification processes.
