Before making any lasting dietary change, it’s better to research a lot and prepare yourself. Learn to make dishes you like, and take things slowly. The period of time needed to make a transition depends on each person. While some are able to change overnight, remember you are unique. Allow your body time to adapt itself. A minimum period of one month is needed to get over ‘withdrawal’ symptoms. This is why people who have bad diets could start with a fast, as a way of quick cleansing. Easing into a new diet may be more successful for some if done under medical supervision.
