Here is what Mercola's site has to say:

Quote:
A critical reading of the current literature certainly supports the dietary trends of decreased carbohydrate intake (especially of neocarbs), increased protein intake, and increased fat intake (especially of monounsaturates and N-3 polyunsaturates). The data that supports these contentions comes from a wide spectrum of disciplines, including the basic sciences, medical science, epidemiology, and anthropology.

The one dietary program that addresses these principles in full, is the so called "evolutionary diet."
The modern inception of this prehistoric lifestyle would favor the consumption of lean meats (preferably wild game or non-grain fed, free-range domesticated animals), fish, seafood, vegetables, fruits, raw nuts, and seed. Notably absent from this dietary genre are dairy products, cereal grains, beans, legumes and concentrated sweets (except for perhaps the occasional foray into raw honey!).
Mercola is supporting the paleolithic diet:

The paleolithic diet is close to Dadamo's diet for blood type O people:

Dr D’Adamo says that our digestive tract retains the memory of ancient times, and so type Os need to eat a typical hunter-gatherer type diet. In other words, type Os should follow a high-protein, low-carb diet with lots of meat and fish but no dairy products, wheat or grains.

If that sounds familiar, it’s because it is – the diet recommended for people with blood type O is simply a variation on many of the typical high-protein, low-carb diets that are currently popular, such as the Atkins diet. Foods you can eat freely include meat, fish and olive oil; foods you can eat in moderation include eggs, nuts, seeds, certain vegetables and fruits; and foods to avoid include dairy products, beans, cereals, bread, pasta and rice. To complement your food intake, Dr D’Adamo recommends lots of vigorous aerobic exercise such as aerobics and running – just like our hunter-gatherer ancestors did!
