"As much as you want" is subjective. I simply eat as much as it requires to not be hungry. I could certainly eat much more than I eat currently but once I am no longer hungry, I stop. I find that exercise suppresses my hunger pangs as well. It is easier to exercise under this kind of low-carb diet.
Thanks for the info.
I'm thinking about doing this later this year, as I could stand to lose about 10-15 pounds off my gut.
I'm doing 45 situps a day, and will try the diet if that doesn't work.
