Eating healthy most of the time and allowing indulgences every once in a while, known as 80/20, is a lifestyle you can maintain forever. This means that 80 percent of the time, you eat lots of fresh fruit and veg, whole grains, lean protein, and healthy fats, and that you cut down on the sugar, processed foods, and alcohol. Then, 20 percent of the time, you get the green light to enjoy some chocolate, a glass of wine, or some french fries. Knowing you can indulge a little satisfies cravings so you never feel deprived.
