I attribute this ability to tune in to what is going on inside my body to Qigong. After about three weeks of doing those simple Qigong daily exercises of nourishing the organs, I noticed not only how much better I felt, but also how much more aware I was of how my body was feeling and reacted to things. It was as if this Qigong exercise helped me tune into the ability to understand my body's messages.
I then started to connect the dots between how I was feeling to what I was eating. This awareness of how I was feeling helped me realize the impact of fresh foods from packaged foods as well as fast foods from home cooked meals. With this new awareness I've started on a new path. Since I want to feel good all the time (or as much as possible) it means I need to give up convenience but in return I will get that feeling of wellness.
Old habits are hard to give up, but the awareness of how much these little daily choices can impact how I feel is rather motivating. I like the probability of moving from feeling “fine” to feeling “fab.”
