Affiliate disclosure

Some links on PureFasting are affiliate links. If you buy or sign up through one, PureFasting may earn a small commission. This does not change the price you pay. It is still a commercial relationship, and you should know about it before you click.

Recommendations, if they appear, are not medical advice. They are not a statement that a product is right for you, and they are not a claim that any product treats or prevents disease.

Active programs: Bookshop.org (book links on the Resources page; purchases support independent bookshops) and Zero (the “Try Zero” link). Every affiliate link is labelled near the link. PureFasting is not in the Amazon Associates program and has no Amazon links. Products marked “Not an affiliate link yet” are examples only, not offers. Commissions do not decide what we list.

You do not need to buy anything to use the guides, the beginner guide, or the tools on this site.

Safety. People who are pregnant, breastfeeding, under 18, have an eating disorder or a history of one, have diabetes or hypoglycemia, take medication, or have a heart, kidney, or other medical condition should talk with a healthcare professional before fasting. Stop a fast and get help if you feel faint, confused, or unwell.
