Re: Newbie to the site and fasting.

It's entirely impossible for us to answer your question.

You gave us no information on your current physical condition.

If you're Kate Moss, then you won't lose but a few pounds.

If you're Rosie O'Donnell, then you may lose a ton or so.

the typical rule of thumb is 1-2 lbs per day.

21 days is quite aggressive for a first fast. The detox can leave you very weak, unless you are exceptionally healthy to begin with.

The suggestion to do a week was a good one. My first fast was 1 week followed with 1 week of juice. I continued to lose a lot of weight on the juice and it gave me more energy to cope with the daily grind. It also was a great transition back to solid foods.
