Guides, free and without a catch.

Seven pieces covering the idea, the evidence, the food, the risks and the conversation with your doctor. All free to read, all general education, none of it a treatment.

None of this is a treatment, and none of it replaces care. If your mood has been low for weeks, see your GP — or in England, refer yourself straight to NHS talking therapies. This site describes a restrictive way of eating; if food feels hard to control, speak to your GP first, and Beat offers free, confidential support. For individual dietary advice, ask to be referred to a registered dietitian.

A written guide (£27) and an online course (£47) are in preparation as separate products. Neither is on sale, and the guides above stay free regardless. Look inside the guidebook · Explore the course
