Ann, You might not see such a large initial loss, because you've been dieting for awhile already, but at least the support and encouragement and accountability of going to the COD will keep you going, and keep you losing.
80 pounds is an impressive amount already, that is impressive, especially since you've battled health problems at the same time.
Anyway, I do believe the program works. If you don't lose it one way, they will adjust the program until you start to see results.
Welcome and I hope you find the encouragment you need to continue your journey to a healthier you
