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.
