From what I understand, GBS folks eat a lot like us! Smaller, nutrient-dense meals with very few empty calories from starches and sugar. I interpret it as surgically-enforced LCing with high risk of complications including malnutrition - which partially explains the hunger. Stomach size/fullness is only one hunger regulator.

I fully support those who choose to go through with it, but it makes me sad that it has to come to that.
