Got my info from book. If Im reading it right the only difference is a higher allowance of carbs daily, 40grms certainly no more than 60grms a day.Alcohol is allowed as it is v.low carb but definately no beer. You are to have one slice of brown bread daily or the same amount of carbs (17grms) in something similair.
Hope this is of use.
Best to read book though.
Sorry for bad spelling as am rushing out to pick up kids.
