Can you explain the .75lbs number you provided? How often do you anticipate a person to lose that much? Care to provide literature for your claims?

Not the GP, but a pound of fat = 3500 kCal. If you use the standard 2000 kCal / day basis, that gets you to .57 lbs fat loss per day.
Also, the 450 pound (204 kg) man who did not eat for an entire year [0] lost 0.72 pounds / day.

That person seemingly turned his health around from 456 lbs to 180 lbs. But he died at age 50. I am scared of fasting because I dont think there are enough studies on humans to understand the long term effects like gallstones and lean tissue loss, especially heart muscle.

He represents such an extreme case, it is hard for me to draw any broad conclusions from his life. The man never had a healthy relationship with food.

1lb of body fat is ~3500 calories. An average person doing average things burns around 2000 calories. You can easily put in your own numbers and get your own results. Just calculate your TDEE(total daily energy expenditure) and look up how many calories in a pound of fat to whatever tolerance you want.
You lose roughly ~0.75 lbs of body fat at normal fasting levels assuming a reasonably active regular sized person. So how ever many days worth of body fat you would like to gain and lose regularly. You would have to eat back the same amount and probably wouldn't want to gorge yourself too much. A reasonable practical limit might be 5 days.
All of that assumes that you want to maintain a set weight. So the real limit is how much you want to eat in a single sitting. Take those calories and average them across as many days as needed to maintain weight.
