The paleo diet eating plan is also known as the caveman diet, or the paleolithic diet. This is a diet that includes such things as animal fats and proteins, vegetables, fruits, some nuts, and seeds. This is a diet said to be the most beneficial to us as a human race as it is the diet we thrived on before so many processed and junky foods came into play. This diet is an easy one to start, and it is also easy to stick with.
