Sorry for confusion. I went through only one 21-7-21 fasting session. First 21 days were easy, except for the initial 3-4 days which were pure (PURE) HELL. Every single cell in my body screamed for food. I felt that my brain and body were bursting, attacking me both at the same time, trying to trick me to eat: at least a little bit of a juicy peach, or a tiny slice of a bread crust, etc. (Things that usually turned to a binge.) I had a HUGE emotional breakdown and felt like the miserabli-est mess in the world and cried and cried … you’ve got a picture.
On the fourth or fifth day I woke up in a morning very balanced and peaceful, without any trace of hunger or any mental desire to eat. And this is how I felt for the rest of those 21 days. I was easily able to fast longer than 21 days, but I didn’t went through a medical supervision--my doctor would think that I’m crazy--so mentally, I was not comfortable to go further without a break.
During those 7 days of the break, I wanted to stay in ketosis, so was careful not to go over 15 grams of carbs. First 2-3 days I was juicing veggie and eating salads and eventually a serving of canned sardines (I know, it was wrong but I craved them) and cooked salmon. I didn’t touch fruit or anything sugary and didn’t have need for it. Through all that time I didn’t use any minerals, vitamins or cleaning stuff except enema on the first few days. I had a few bowel movements during the break, not particularly unpleasant.
When I started the second 21-days-part I was wishing I didn’t stop on the first place. Beginning was hard, but the hardest part was the last week when I was very, very weak and I was mostly spending days in a bed trying to read or sleep, couldn’t do neither.
When I started this adventure, I was somewhere between 200 and 210 pounds. (I was so frustrated with my weight that I didn’t want to weigh myself). And when I finally stepped on a scale I was 159, so I lost 40 to 50 pounds, maybe even more.
So, once I finalized that 21/7/21 adventure I took things slowly. To tell the truth, I attempted to fast a few times but it was too much for me. However, I was able to function and feel ok on a very small amount of food. I lost any desire for junk and very often I ate only once a day. I lost additional 20 pounds in approximately 5 months. That was not bad, but still having 15-20 pounds to go I kind of lost patience. So in March, I undertook 2 weeks fast and I finally lost those last, stubborn 15 pounds. March-fast was not as hard, it was kind of routine. I’m now fluctuating between 120 and 125 pounds, which is more than fine.
Two things that I learned on this forum and I found very useful are: not to drink water unless you are thirsty and to drink warm water if you have heartburn. As you probably already know, no one agrees regarding activity level, so I applied whatever fitted me: when I was out bursting with energy I went to gym when I was weak I stayed in bed. I didn’t work at that time, but having some family obligations I was driving in average 40 miles per day, walking a dog, painting a bedroom, doing housework and similar.
My diet before fasting was pure junk, $20-$30 of pure junk per day. I had very stressful 60-70 hours per week job so in addition, I was flooding myself with gallons of latte and diet coke.
Allan Cott said in his book that fasting compared to diets gives another perspective on the food and that--more than anything else--was the truth for me. Somewhere during the fast it happened that eating chocolate became as undesirable as chewing a shoe (a dirty shoe). Hard to believe, but this is how my body and everything in me feel. I think that being overweight is not a matter of discipline or character but just being on the wrong side of the perspective or the ‘switch’. Some people may achieve that through dieting, I needed to fast and I’m very glad that I did it.
I hope I answered your questions. I wish you so much to succeed.
