Here's an introductory article that may help.
"5 Tips for Going Raw", an article written by Marc David, M.A. in 2014 and published by The Institute for the Psychology of Eating, is a well laid out discussion of some essential issues to consider and ways to prepare oneself when thinking about making a lifestyle change from cooked eating to eating raw. In this article, Marc focuses his discussion primarily on a plant-based raw lifestyle. However, I believe the content of the article is also relevant for adopting other raw lifestyles. For example, Marc writes about some motivating factors for choosing a raw lifestyle (e.g., the health benefits), equipping one's kitchen with essential tools, and some psychological adjustments needed to adopt a raw lifestyle.
I believe this is a good introductory article for anyone considering a lifestyle change from eating cooked food to eating raw.
