“There is, however, more evidence for a health risk from eating too few vegetables. That is really the risk of a high-meat diet, those meat calories are displacing vegetable calories.”

Isn't a calorie just a calorie though? Or is this in regards to what comes alongside those calories?

CICO is true at the highest level but not in general. The effect 200g of protein has on your body vs. 200g of carbohydrate (in particular insulin, ghrelin, etc) means not all calories are created equal.

Energy-wise, yes, but the devil is in the details. If I had to infer the meaning here it's that high protein = constipation = not good. Vegetable calories include fiber which is important to insure you're processing things efficiently. Additionally, good vegetables (unfortunately not the ones you can get at the store usually) contain lots of great vitamins and minerals. I would be curious if they mean a typical American chain store vegetable which demonstrably has almost no nutrition compared to it's natural counterpart.
