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.”
Eat polyunsaturated fats. While saturated fat leads to the body's retention of visceral fat, causing abdominal girth and excessive weight gain, studies have shown that a diet high in polyunsaturated fat helps promote the production of muscle mass instead of body fat. Polyunsaturated fats can also help reduce cholesterol levels in the body, lowering the risk of stroke and heart disease. Sources of polyunsaturated fats include:
Or skip your favorite early-morning show—whatever it takes to grab a few more minutes of sleep each day. When researchers at the University of Chicago studied men who were sleep-deprived, they found that after just a few days, their bodies had a much harder time processing glucose in the blood—a problem common in overweight diabetics. When the individuals returned to a more normal seven to eight hours of sleep a night, however, their metabolisms returned to normal.
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.
