When my daily work meant I was moving a lot and outside every single day, I was thin. I burnt up the calories I ate. Never even gave a thought to what I did eat. No matter what a diet guru says, it will always matter to balance eating with your activity. In fact if you ate a whole pie by yourself and was still active all week after that, you would even gain weight. Because your metabolism in good working order, by moving enough and often, adjusts to occasional face stuffing. Country folk work hard with their bodies. As nature designed.
