This is an excerpt from a longer seminar in which Dr. Allott explains the physical causes of anxiety, fatigue, agitation, insomnia and sugar cravings. It explains the way your body reacts to the different fuels, or foods, you consume throughout the day. Instead of addressing food in terms of calories or fat content, we are going to examine dietary choices from the perspective of brain optimization. The goal is to give you an understanding of how your food-based fuel choices can help your body and brain remain energetic and clear.
