Mark says that 50-100g carbs is great for losing weight, and 100-150g of carbs per day is great for maintaining weight...

A small/medium sized sweet potato has approximately 20-25g carb.. This is no different than several primal-accepted fruits... Yet Mark says to moderate sweet potatoes to only a few times per week, while he says you can enjoy fruit daily.

Why can't we just remove fruit from our diet and instead replace it with 1-2 sweet potatoes? Less fructose, no more tooth pain from the acid in fruits, and same carb value.
