Fasting isn’t a new thing, the human species has been fasting and feasting for ages! It has been used not only for weight loss but to improve concentration, extend life, prevent Alzheimer's, prevent insulin resistance, and even reverse the entire aging process. Food preservation and storage is a relatively new invention - the cavemen certainly didn’t have a way to store foods without them going bad. They would hunt, gather, and feast because they didn’t know when they would be able to feast again. And when food was unavailable, they just didn’t eat. In recent years, the practice of fasting for health benefits has re-entered the public consciousness and millions of people are beginning to rediscover the powerful positive changes that can be achieved through intermittent and extended fasting.
