Doing 80/20 can be challenging for people who like to follow (or are used to following) more restrictive diets. With the 80/20 diet, you need to be able to look at your diet as a whole — and planning is key. Sheri says, "If you consider the total number of meals you eat weekly (assuming you eat three meals a day), four of those meals (20 percent) can be less healthy."
Think about your commitments, and then schedule and plan accordingly! Do you have a date? A dinner party? A work function? Plan to use those occasions as your indulgent meals, and eat healthy the rest of the time.
