Why: "Oats fill you up with fiber without added sugar, like most highly processed cereals," Glassman says. "Nut butter provides healthy fat that will keep you satisfied, but won't hold onto water like sugary and salty packaged foods. (That being said, be sure to check labels and pick items with no added salt sugar!) Berries fill you up with fiber and water volume without adding a big carb load to your morning."
Your body can retain water when your sodium and potassium levels are out of whack, Bannan says. In addition to keeping sodium in check, consume potassium-rich foods to maintain the balance and de-puff your belly. Try incorporating 1 medium baked potato without skin (610mg), 1/2 cup white beans (595mg), 1 cup cooked spinach (839mg), 10 dates (466mg), or 1 cup edamame (676mg) daily.
Kneel on the floor with your knees hip-width apart, toes tucked under. Extend your arms out straight in front of your chest, palms facing down. Lift your chest and press your pelvis forward as you hinge backwards, arching slightly through your lower back. Pause and focus on opening up your chest while also keeping your ribcage down and your belly button drawn into your spine. Slowly return to the starting position. That’s one rep. Repeat up to 10 times.
Dr. Rasa Kazlauskaite at Rush University Medical Center suggests filling half your plate with vegetables so you don't have room for unhealthy foods. Eating more vegetables not only helps whittle your waist, but also lowers risk of heart disease, cancer and diabetes. A vegetable-filled lunch might include 4 ounces of grilled chicken breast with 2 cups of mixed vegetables such as broccoli, cauliflower and carrots sauteed in 1 teaspoon of olive oil with 1 cup of roasted red potatoes. This meal contains 545 calories.
Cat Kick: Stand with feet together, arms extended out like airplane wings. Exhale, and lift the right leg forward and up. At the same time, sweep the arms forward at shoulder level and round the spine, like a cat. The navel should feel as though it's pressing toward the spine. Inhale, and open back up and return to the starting position. Repeat with the left leg, alternating for 20 repetitions.
Moves like the tolasana and the eight subsequent ones we did that day are representative of a shift that ab exercises have taken in the past decade or so. Previously there was a tendency to isolate the abdominal muscles to give each one an individual workout — crunches for your rectus abdominis, bicycles for the obliques — but as Olson points out, that's not the way it works in real life. "When you're reaching up to get something, picking up a baby or bending down, you need all the muscles to work together," she says. "Instead of targeting each one, you should aim for functional fitness, where the muscles work as a unit."
Though it's been months since its debut, the book continually spikes on Amazon's Movers and Shakers list — its roundup of the top-selling products across the site — and it's currently listed as the No. 1 bestseller in the Diet Books category. Naturally, this begs the question: What's all the hype about? Aside from the famous author — and the fact that the title suggests fixing a problem just about every human struggles with (just look at search traffic for "flat belly" and "flat stomach" exercises). Is it all just marketing hype?
