MUFAs, or monounsaturated fatty acids, are the cornerstone of the Flat Belly Plan. These are plant-based fats, so the easiest way to remember them is to look for healthy fats that aren’t from animal sources, such as avocados, nuts, seeds, oils and olives. A study done through the American Diabetic Association found that a diet rich in MUFAs worked to reduce belly fat.
Do stability training. How do you turn a bicep exercise into a core workout? Add a stability challenge! Do the exercise in a standing position and add an unstable surface under your feet. That way you have to brace your core and use your abdominal muscles to balance and stay upright while you work your arms. You can add this kind of balance challenge to any exercise. Use tools like a wobble board or a bosu to enhance your stability training.
Another imbalance that plagues the abs is between the obliques, the muscles that cinch your sides. You have two sets on both your right and left, and if you show them love, they'll give you a nice hourglass shape. Sadly, your left obliques start out at a disadvantage, says Hahn. Blame your heart, which takes up extra space and makes the obliques difficult to tone—an issue that's compounded if you're right-handed. "Think about where your mouse pad is," says Hahn. "Then you shake hands, change the radio station in the car—you do so much with your right side, making it stronger."
The two figures standing in front of me one recent winter morning could not look more different. On the right is Carrie McCulloch, MD, a musculoskeletal anatomy expert and the medical director for Kinected Pilates studio in New York City, who is sizing up the shape of my waistline. Dr. McCulloch's own midsection happens to be perfectly rounded because she is only weeks away from giving birth to her first child. On the left is her assistant, Mr. Bones, one of those hanging skeletons that teach medical students how the thigh bone's connected to the hip bone. Mr. Bones doesn't actually have a waist, just a hollow space between his ribs and pelvis.
Zero Belly Smoothies are supercharged with belly-flattening nutrients. The key: Each drink is packed with protein, healthy fats and fiber.

A healthy lunch should consist of half non-starchy vegetables, with the other half split between whole grains and protein, says Rumsey. “That way, you have some carbs but not too much,” she says. Pick a dressing low in sugar and sodium—olive oil with balsamic vinegar will give you a little healthy fat to keep you full and help absorb nutrients from your veggies. (Here are more food combinations that help you get the most health benefits.) Add at least three vegetables, 3 to 6 ounces of a protein like chicken or beans, and just a thumb-sized amount of extras for crunch or flavor such as dried fruit, croutons, and olives, says Rumsey. Double wash canned beans before adding them to your salad to rinse away their gas-forming, bloat-producing properties, says Crandall.
This crunchy and creamy pair will be a perfect low-calorie snack to tide you over between meals today and throughout the week. Thanks to their high water content, carrots and cucumbers are two of the most satiating and hydrating low-cal veggies out there.
