Everything works together. I read a book at thanksgiving that outlined how to put your body into fat burn mode and it works but you have to be good on the foods you eat and exercise five to six days a week. If you want to burn fat take time to read books that set your diet to the amount of protein, carbs, and fat. If you monitor these by your daily calorie intake which is set by your height and weight you will burn fat. It will not matter if it is old or new. You just keep on till you hit your goal weight. Good Luck
