I've had good experiences with fasting and I'd recommend it to anyone. My longest fast so far was 7 days. No food, just water. I lost about 20 pounds.
I worked from a book by Dr. Joel Fuhrman, and have since undertaken a few more fasts, with phone guidance from another doctor at Dr. Fuhrman's office.
When I fast, I rest the whole time. The first few days of my 7-day fast, I hung out with a friend, did a bunch of reading, and watched some TV, but by the end of the fast, my energy level was so low that even trying to watch TV was too demanding for me.
Caveats: I am not a doctor, but the book I was working from placed a "safe fasting" limit of around 40 days, with 30-35 being the real practical limit in nearly all cases, iirc. The book also recommends medical supervision for anything more than a 7-day fast. My doctor said the same thing.
Why do you fast for so long if it's such a bad experience? If you'd do a 16h fast every day you'd be fit all year round and still have plenty of energy (for me, more energy than without fasting). Check out leangains.
