I did, BeeGirl. The reason I tried a week-long fast in the first place was that I had been reading about the benefits of autophagy (the body breaking down its own damaged and moribund cells for energy thereby making way for fresh replacements) and an increase in the body’s own production of human growth hormone which spikes around the fourth day of a fast. By then I had been doing 48-72 hour fasts once a month for about 6 months and I had found that I really enjoyed them. The second day energy boost was a particularly fun phenomenon. I could, and did, walk for hours, and I chatted excitedly about a million things all day.
What I found with the week fast was that I experienced a decrease in physical energy the second half of the week but a marked increase in mental energy. My thoughts were very clear and precise and I completed two major writing projects that had been lingering unfinished far too long. I also could very clearly see the effects of the HGH and autophagy in my skin. I looked noticeably younger, pink cheeks, tiny pores, loose skin a little snugger. My OH calls it “fast face.” 😀
