How much of a connection is there in determining what we feel to what we ate and how our body responds? With an understanding of food as molecular components providing the building blocks for protein with a physiological function, and add in to the mix external stimuli and voila: the gamut running from physical and mental energy to draining addictions has its niche.
What foods make you happy? What foods lighten you? How do you know what feelings your food inspires you to feel? A food diary is what I recommend to all my clients. This is the most personal mode you can choose in actively consciously connecting the variables in day to day life with a tangible written truth of your own choices and words.
