The next time you consider counting calories, consider this: it’s easy to simplify a concept to the point that it’s no longer true. Even though, simple thermodynamics say an excess number of calories can cause an increase in body size, "calories in-calories out" equation is a drastic oversimplification. It doesn't take into account so many more variables that affect both sides of the equation.
On the blog, I explore the hunger hormone, ghrelin, as one explanation as to why calories-in and calories-out equation is not an end-all, be-all equation. Our bodies have a whole host of complex processes and mechanisms, including hormones, that determine metabolism and preferred weight ranges.
I'd love for you to weigh in and share your thoughts and comments.
