Read the food lables!

Here's one secret of The Dule Diet: What you need to know about serving sizes is often already there on the label. There's nothing special about The Dule Diet serving sizes. They certainly diverge from what too many of us have habitually come to dish out, but they're right on target with what the USDA and responsible nutritionists everywhere have been recommending for years.

So any packaged food—and there are good ones, even as you get much pickier about using only whole foods—will tell you right on it how much you should eat of it and how many portions that particular package is meant to provide. In most cases, those bits of information will line right up with The Dule Diet recommendations.
