Ketogenic diet: guides and precautions

If you arrived with a specific keto question, start with the three essential guides. They explain the concepts, help you read food information and identify precautions to discuss with a healthcare professional.

Search for a food or a topic. When comparing answers, check whether they refer to the same preparation and amount. A general list, a recipe and a personalised meal plan serve different purposes. None of the published examples knows your medical history or can determine what you should eat every day.

The foundation guides use question headings and a contents list to help you reach a relevant section. Links between the three topics take you from a food question to its context or precautions. You can also browse articles in English or consultar os artigos em português.

The three essential guides were updated on 7 September 2026 using institutional and scientific sources, including Cochrane, the NHS, WHO and Diabetes UK. Each guide links to its references and identifies the editorial update with AI assistance. These texts have not received independent clinical review.

Personal experiences and general explanations do not demonstrate that a diet treats a disease or works for everyone. CetoPlan does not replace a consultation or promise weight outcomes.
