There is very little comparison between the Health Made Simple program and the Paleo Diet, which technically has many acidic aspects, is not vegetarian, promotes dairy and is fundamentally flawed. The Paleolithic Diet is a modern nutritional plan based on the presumed diet of Paleolithic humans. It is based on several controversial premises, the most important of which are: that human genetics have scarcely changed since the dawn of agriculture, which marked the end of the Paleolithic era, around 15,000 years ago; and that modern humans are adapted to the diet or diets of the Paleolithic period; and that it is possible for modern science to discern what such diets consisted of. The Paleolithic diet consists mainly of fish, grass-fed pasture raised meats, eggs, vegetables, fruit, fungi, roots, and nuts, and excludes what are perceived to be agricultural products; grains, legumes, dairy products, potatoes, refined salt, refined sugar, and processed oils. It argues that certain portions should be established for the balance of nutrients to maintain homeostasis.
