But you don't have to be "perfect" all the time. I follow the 80/20 rule. With 80/20, you can go out socially and enjoy a meal (or a cocktail!) with friends, but most importantly, it makes the whole clean-living thing feel doable for the long run. What's 80/20? 80% of the time you focus on eating clean, good-for-you foods, and 20% of the time you have the freedom to indulge as you please.
