TRF is technically a version of IF. There are no definitive long-term studies that prove which IF or TRF protocol is the &ldquo;best.&rdquo; Being a purist is not necessary, although calorie restriction and IF are not the same.</p> <p>We evolved in a world of feast and famine. (Famine is fasting, but not by choice—i.e., starving.) We now live in a world of only feasting, with groceries within blocks, a fridge/freezer in your kitchen, another freezer in the basement, and a beer fridge in the garage. There is no shortage of food in our modern environment, but that does not mean feasting without fasting is normal.</p>
