6. Strive for a diet that’s pretty good — not perfect.
Although Blake Lively gave birth to her daughter in December 2014 and had to shape up quickly to play Nancy in The Shallows the following year, she didn’t try to live a life devoid of pizza or pasta (or joy), or count a single calorie to reach her goals. Instead, she simply stuck to a mostly homemade, balanced diet of proteins, vegetables, fruits, slow-burning starches like sweet potatoes, plus healthy fats like avocado, coconut oil, and grass-fed butter, according to Blake’s trainer Don Saladino. Her goal: to put good-for-you foods into her body at least 80 percent of the time — and to leave room for treats like mac and cheese when cravings call (as they do!).
