Core exercises will strengthen your abs, but they won’t eliminate the fat that lies beneath them. To do that, you have to ramp up your overall calorie burn with cardio (running, walking, biking). A Duke University study found that people who did moderate cardio for 178 minutes per week (roughly 30 minutes of walking six days per week) gained hardly any visceral fat over the course of eight months. Participants who worked out at a higher intensity (jogging) for a similar amount of time saw even better results — reducing their belly fat by almost 7 percent. To maximize your workout, try interval training, which alternates between high- and low-intensity cardio.
What’s more, your body digests protein more slowly than carbs, so it keeps you feeling fuller longer and zaps your need to needlessly snack. “During weight loss, you want more protein—to prevent hunger, enhance satiety, and minimize muscle loss, as long as there’s some degree of physical activity,” Tom Rifai, MD, regional medical director of metabolic health and weight management for the Henry Ford Health System in Detroit told Prevention.
Adult women require anywhere from six to eight hours of sleep every night. If you're staying up late on the regs and aren't meeting that minimum, you'll throw off your natural rhythm, which can cause your body to freak out and start overproducing hormones (including cortisol). By getting the right amount of sleep every night, your body and metabolism will stay regulated — keeping you and your tummy on point.
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
