Whatever diet you follow, whether it's plant-based, Paleo, or low-carb, follow the 80/20 rule of eating. This means eighty percent of the time, you eat meals and snacks that are healthy, then you indulge the rest of the time, if you feel the urge.
Swapping most of your meals for healthier options is an easy way to "diet" without feeling deprived. For even greater results, Beachbody trainer Autumn Calabrese, creator of the 21 Day Fix and 80 Day Obsession fitness and nutrition programs, recommends the 90/10 rule, which can be especially helpful to jump-start your efforts or if you have hit a fat-loss plateau.
