When we look at metabolism and brain health, it is easy to forget that they are intimately connected. Metabolism may evoke visions of food being digested and turned into energy, however, cellular energy can be made without any food at all using appropriate light frequencies. Regardless of how it is made, bioenergetics is the most important determinant of health and wellness, especially the brain and mental health. The production of hormones and neurotransmitters has strict bioenergetics requirements that must occur at the exact right time. The timing nature and circadian biology are extremely important when considering this connection. Too much energy at the wrong time or too little energy at the right time, both result in poor health outcomes. When we can optimize the bioenergetics and the timing of the body, we can see an amazing transformation for the better.
