Instead of focusing on "eating clean," Devon suggests controlling your calorie intake and being mindful about creating a sustainable calorie deficit. Aim to eat lots of lean protein, as she says it's "the easiest way to lose body fat," because the protein fills you up on fewer calories, keeps you satiated, and also helps preserve lean muscle mass. For protein, you need about 0.8 to 1.8 gram per pound of body weight, depending on how active you are.
