New research also shows a younger body needs less calories from protein because a younger body is more sensitive to protein's fat-loss and lean muscle building benefits.
For an easy way to eat yourself leaner and younger at any age while taking years off your looks follow this 1 simple flat stomach rule:
Starting at age 18-20, gradually reduce the amount of carbohydrates you eat but raise the amount of your protein and healthy fat you eat to take the place of those calories.
Doing this can help create a younger, faster fat-burning metabolism without "dieting" while keeping you more satisfied and less hungry.
