Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
Notes: Chop the sweet potatoes and halve the Brussels sprouts, and place on a sheet pan. Drizzle with 2 teaspoons olive oil, season with salt and pepper, and toss to coat. Roast at 450°F (230°C) until tender, about 15 minutes. Brush the chicken with 1 teaspoon olive oil and season with salt and pepper. Grill over medium-high heat until marked and no longer pink in the center, about 5 minutes per side.
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
