Better book to me is: Burn the Fat, Feed the Muscle. http://www.burnthefatfeedthemuscle.com/
Simple answer is clean eating. Eliminate everything that is not real food. No chemicals, preservatives, artificial colors or flavors, Trans fats. Severely limit refined sugars, white flour, animal fats, cut out those sodas & other drinks that are empty calories. Avoid GMO's. That is just a good start. Stay in the outer isles of the grocery store, fresh meats, poultry & fish, fresh produce & simply frozen foods. Stay away from processed foods (bags, cans, boxes & jars & prepared frozen). Then understand the proper portion sizes, how to get the right amount of protein & the right balance of good carbs & lots of non-starchy vegetables. Then know when to eat which of them in several smaller meals a day instead of 2-3 big ones.

And of course get plenty of exercise, both cardio & muscle building. There are no short cuts unfortunately. The book is pretty heavy reading & it takes a while to get it all but it works. Discipline is the hardest part. Good luck with your quest.
