Synopsis

Fat is not just stored energy, it’s a complex organ that controls crucial hormones and communicates with your brain, immune system, and metabolism. It's one of the most powerful organs, but it can be one of the most dangerous ones, as well. When there’s too much of it, fat can trigger inflammation, disrupt hormonal balance, increase your risk for nearly every major disease, and significantly shorten your life.

What is fat really, and how does it function? When does it become dangerous and can the damage caused by excessive amounts of fat be reversed?
