Metabolism. There isn’t perhaps a more frequently used word in the weight loss (andweight gain) vocabulary than this. Indeed, it’s not uncommon to overhear people talking about their struggles – or triumphs –over the holiday bulge or love handles in terms of whether their metabolism is working, ornot. Doctors, too, often refer to metabolism when they try and explain why starvation andwater-loss diets aren’t scientifically of medically responsible; since, alas, they do notinfluence or take into account metabolism (there’s that word again!).So, for all of the usage that this rather daunting and biologically-charged word enjoys inour world, you’d comfortably assume that people understand it, right? Or, at least, they have some fundamental information when it comes to how to speed uptheir metabolism, right? Wrong!
