“I have a very fast metabolism, so incorporating healthy carbs into my diet is a must,” the 5’10” Army Reserve lieutenant, 26, tells PEOPLE.
Barber works out five days a week, and likes to incorporate military-style moves into her training, such as flutter kicks, sit ups, planks, lunges and squats.
“My workout routine is really focused in my abdominals and my inner thighs,” she says. “I keep it light because I’m naturally slim, and it doesn’t take much for me to gain that muscle definition.”
Check out her daily food log below, and pick up the new issue of PEOPLE, on newsstands Friday, to read more about her diet.
2½ liters of water
Protein shake made with ½ cup frozen strawberries, 8 oz. almond milk and 3 scoops Purium L.O.V. Super Meal
Toasted blueberry bagel with light cinnamon-raisin cream cheese
Open-faced sandwich with multigrain bread, smoked turkey, American cheese, slice of Bibb lettuce, tomato, spicy peppers and mustard
Seared salmon with light seasoning salt
Steamed broccoli with low-fat shredded cheddar cheese
Oven-roasted potatoes with rosemary, onion, salt, pepper and olive oil
Krispy Kreme glazed doughnut
Barber’s morning shake gets the seal of approval from dietitian Keri Glassman of nutritiouslife.com, but her bagel and cream cheese breakfast is “highly processed.” Glassman suggests swapping in a salad for the open-faced sandwich at lunch and adding almond or peanut butter to Barber’s banana snack for a “little protein and healthy fat.” And while the dinner is a “good, balanced meal,” the donut “is a fat and sugar bomb!”
