Let's get a few thing straight, you are not resetting your metabolism.
You are increasing certain hormones that regulate your metabolism.
All bodily functions are balanced, this balance is called homeostasis and it's what regulates just about every function in the human body. One hormone goes up, another goes down, this is often referred to as a negative feedback loop. Think, Test/Estrogen or Insulin/Glucagon.
By cheating or refeeding you are able to boost insulin as well as leptin which will upregulate t3, HGH as well as Testosterone all which decline during hypocaloric periods.
