I do GO and mix in some PP. Differences are little really. I think both plans are REASONABLE and HEALTHY. I am not so convinced about Atkins...sorry you ATKIDS!

Basic premises of GO:
Low carb-50g
50% High MONO and POLY unsaturated fats, LOW saturated fats
High Fiber-25g or more
NO KCAL RESTRICTION (like most LC plans)
LC veggies, 1/2 c LC fruit
8 oz fermented milk products daily
Normal protein (haven't quite figured out what NORMAL is...)
Wine okay and water water water.

Basic PP premises:
Low carb-30-55 for weight loss and corrective status
Adequate protein- dependend on lean body weight and activity level
Good on fruits, veggies, and fiber
Fat is your friend (no differentiation of types.
Drink til you float
A glass of wine is good for you.

I think that about covers it.

What I do different is take carbs up to 72 limit per Life Without Bread. I think that's about it. Feel free to ask me any thing!

Are you interested in being a buddy???
