Even though we've all been told to exercise more to "burn off" fat, the key to fat loss is eating right in the first place. While it is true that the more muscle you gain through exercise, the better chance you have of losing body fat, the majority of the results come from what you eat. And, it's not as simple (or as torturous!) as counting calories.
While there is no magic, one-size-fits-all diet, there are certain scientific rules and principles that lead to real results. Having this knowledge of what and how to eat helps heal your relationship with food so it's no longer this thing you restrict & torture yourself with...but something that nourishes the results you desire.
