I love your spiritual name!
My experience with pi gu practice is I consumed reading Tom Tam's interpretation while
training with him, tai chi and tong ren and chigong energy practice in a large group setting.
For me, I understood it was not to be fasting per se. The guidance was to eat when hungry.
This was new for me to step out of regular time for meals which I had been conditioned by for
many years here in America. I realized I didn't know when I was hungry; that I hadn't been hungry for a very long time.
I did the daily exercises recommended in his book that include chigong standing practice, building the chi in the lower dantien and circulating chi and building in all 3 triple burners. And, one that I found potent for me was imaging my stomach and compaciting the chi with my palms before my belly. Also, rubbing my belly clockwise and counterclockwise when grounding the chi down my central channel to close my morning practice.
Naturally, I was eating more like one main meal a day and perhaps a piece of fruit and vegies.
I released about a pound a day, 14 pounds in 2 weeks!
It was a miracle for me to realize that this pigu/chigong state could help rev my metabolism and help me be more in tune with when I am hungry and eat then, not from habit or emotional reasons.
Sounds to me that you were following a protocol you thought was right while you continued to have your body become weaker. Rest is so important in this practice, to relax when energy is low, and not push ourselves or false revving with caffeine.
Were you trying to release weight or toxins in your body? From what you said, perhaps you were in a healing crises when you felt weakened and you body was naturally healing and coming more into balance.
During weight loss class with Tom and other practitioners, we do put the lazer on ST meridian, but usually lower toward the abdomen, T24-26 and also CV 4-6 and as we relax as a group, several practitioners are intending shrinking our stomach with chigong energy and movement.
For fun, we have measured our waists and hips prior to an hour pi gu weight loss class and afterwards. We have lost inches from 1/4 to one woman who shrunk 2 and 1/2 inches in 1 class! We also have a scale and people have lost 1/4 pound to several pounds.
Each person's body is unique to their own way of storing fat, water, lymph flow etc.
Thank you for sharing your experience and I hope mine is helpful to you!
