Different people have different approaches to raw foods and diets. There is no single answer as to how you should transition to raw foods, or add more raw foods to your existing diet, because the answer is different for everyone. What is right for you at this very moment may feel wrong in two or three years because our bodies are constantly changing and evolving. These changes mean that your nutritional and dietary needs also vary based on a variety of factors, from how old you are, and how active you are, to the levels of psychological and emotional stress that you experience in your day-to-day life.
One of the best things you can do when it comes to diets and food, is to tune into your body and listen to what it tells you, and the signals it sends you. When you do, you will discover that your body quickly tells you about what works for it and what doesn’t. At the same time, this process does happen over night. If you are used to eating all kinds of food, including those that contain a lot of added sugars; and you consume a lot of caffeine to get yourself through the day, then the process of tuning into your body may take some time.
Going from eating a diet full of processed and cooked foods to a diet rich in raw foods may not even be realistic for you at the moment. So the best solution is to start varying the foods that you eat. Introduce raw foods slowly and see how you feel after eating them. You may want to start a journal in which you record what you eat and how you feel. Keeping such a journal over time, will enable you to see patterns that you were not aware of before.
