We are not biologically identical to our Paleolithic predecessors, nor do we have access to the foods they ate. According the eat clean diet book pdf his online profile, he is a tall, lean, ripped and agile 30-year-old.
He and his family eat really healthy, too. They hunt and fish their own meat. Between foraging, building sturdy shelters from natural materials, collecting firewood and fending off dangerous predators far larger than himself, Grok’s life is strenuous, perilous and physically demanding. Yet, somehow, he is a stress-free dude who always manages to get enough sleep and finds the time to enjoy moments of tranquility beside gurgling creeks.
He is perfectly suited to his environment in every way. These guidelines incorporate many principles of what is more commonly known as the Paleolithic, or caveman, diet, which started to whet people’s appetites as early as the 1960s and is available in many different flavors today. Proponents of the Paleo diet follow a nutritional plan based on the eating habits of our ancestors in the Paleolithic period, between 2. 5 million and 10,000 years ago. Most Paleo dieters of today do none of this, with the exception of occasional hunting trips or a little urban foraging. Almost equal numbers of advocates and critics seem to have gathered at the Paleo diet dinner table and both tribes have a few particularly vociferous members. Critiques of the Paleo diet range from the mild—Eh, it’s certainly not the worst way to eat—to the acerbic: It is nonsensical and sometimes dangerously restrictive.

Most nutritionists consent that the Paleo diet gets at least one thing right—cutting down on processed foods that have been highly modified from their raw state through various methods of preservation. Examples include white bread and other refined flour products, artificial cheese, certain cold cuts and packaged meats, potato chips, and sugary cereals. The rationale for such constraint—in fact the entire premise of the Paleo diet—is, at best, only half correct. Because the human body adapted to life in the stone age, Paleo dieters argue—and because our genetics and anatomy have changed very little since then, they say—we should emulate the diets of our Paleo predecessors as closely as possible in order to be healthy. Obesity, heart disease, diabetes, cancer and many other “modern” diseases, the reasoning goes, result primarily from the incompatibility of our stone age anatomy with our contemporary way of eating. Diet has been an important part of our evolution—as it is for every species—and we have inherited many adaptations from our Paleo predecessors.
