If you've ever struggled with losing weight and keeping it off, I don't have to tell you it's a challenge. You already know.

What if losing weight could be as easy as flipping a switch? I know that sounds incredible. But now there's an abundance of research telling us that may be possible. In his new book, The Fat Switch, Dr. Richard J. Johnson, presents news-breaking, science-based studies that will reverse current thinking on both the cause and treatment of obesity.

And by looking at why people gain excessive weight, Dr. Johnson has discovered why obesity is so hard to treat, and why so many people lose weight only to rapidly regain it. Based on his breakthrough research, Dr Johnson provides a detailed plan on how to prevent weight gain and to lose weight. He also lays out how this research will soon result in treatments to end obesity, something that has been the Holy Grail for those suffering from being overweight.

In a nutshell, this is what he's uncovered from decades of research: Those of us who are obese eat more because of a faulty "switch" and exercise less because of a low energy state. If you can learn how to control the specific "switch" located in the powerhouse of each of your cells, the mitochondria, you hold the key to fighting obesity. So, if you've noticed you have less energy, tire more easily with exercise, or struggle to burn fat, take heart. We now know the reason why. And in just a few short moments, so will you.
