The basic premise of the diet is simple. We should eat only what our hunter gather ancestors ate, because over hundreds of thousands of years, the human body has evolved to perform best using that fuel. Followers of the paleo diet (as it is called by people far cooler than me) eat unprocessed meat, fish, eggs, non-starchy veggies, fruit, nuts, and seeds. They do not eat dairy products, grains of any type, beans, sweeteners, processed foods, or alcohol.
Proponents say the paleo diet increases peoples’ energy levels, helps them lose weight, lowers blood sugar, and reduces cardiovascular risk factors.
There aren’t any statistics about how many people have “gone paleo” but the diet is getting increasingly high profile media coverage, and generating lots of cocktail party conversation. There are also rumors that a number of celebrities are following it.
