The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
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.
9. Make sleep a priority. If you have a baby or young children at home, you know that getting a good night’s sleep can be a challenge. But logging enough Z's is crucial when it comes to losing weight. According to a 2014 article published in the Annals of Medicine, sleep deprivation may affect hormones that regulate your appetite, and that can lead to weight gain. To get more shut-eye, keep your bedroom at an even temperature and stick to a regular bedtime routine, recommends the Centers for Disease Control and Prevention.
Use the meal as a reward for a week’s worth of hard work, or the completion of a project you’ve been dreading. “It’s OK for people to blow one meal a week without feeling guilty,” says James W. Anderson, M.D., director of the Metabolic Research Group at the University of Kentucky in Lexington. “If you follow a healthy diet 95% of the time, you can relax and enjoy yourself the other 5% of the time without gaining weight.”
Researchers think belly fat is distinct from other types of fat — like the stuff under your skin or around your arms or thighs, which doesn't necessarily have negative effects on health — because belly fat could be a sign that you have more visceral fat. That's a type of fat that accumulates around internal organs, impairing their functions and raising stress levels.
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.
