For the record, eating low GI food has a whole section in the book and they mention that you should avoid eating so that you get insulin spikes. They also mention at various points how to structure your fasts so that it fits into your life style and allows you to avoid compensating on non fast days. It's called the fast diet, but fasting is only one small component.
Fasting can only go so far.
Eating only fruits and veggies will not last for most people.
Skipping foods your body needs leads to cravings which are most easily satisfied by cramming donuts, chips, fries, soda etc down your throat. But those foods do not satisfy for long and your cravings take over and you get hungry again quickly.
Eating low GI is a good idea always to keep insulin from spiking as that leads to diabetes/metabolic syndrome.
Weight lost through fasting/restrictive dieting etc is not usually permanently lost. Most people boomerang back, sometimes heavier.
