Napping may be an easy way to catch up on some missed shut-eye, but dozing off in the middle of the day does nothing to aid weight loss. In fact, research has found that people burn fewer calories when they sleep during the day and log their waking hours after the sun’s gone down. To come to this finding, researchers at the University of Colorado at Boulder studied 14 healthy adults for six days. For two days, study participants slept at night and stayed awake during the day, then they reversed their routines to mimic the schedules of night owls. When participants slept during the day, researchers found that they burned 52 to 59 fewer calories than they did while catching their Zzzs in the evening—likely because the schedule messed with their circadian rhythm, the body’s internal clock that plays a major role in metabolism function. If your circadian rhythm is out of whack, a separate study by University of Colorado Boulder researchers suggested spending a weekend in the wilderness to get it back on track.
Ultimately, long-term weight loss requires some short-term behavior change and healthier habit formation. That's why we created our Good Housekeeping Nutritionist Approved Emblem, which exists to help turn smart food choices into healthier eating habits. All GHNA foods and drinks make it easier to find — and eat — good-for-you foods without additional time, effort, and cost. We target the lifestyle-related factors that make healthier eating hard, and find simple but creative solutions that actually work! Look for the emblem on labels wherever you shop for food.
Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.
A big reason to incorporate more strawberries into your diet: not only do they taste delicious, but a study from Harvard Medical School found that an increased intake of flavonoid-rich fruits, like strawberries, could help prevent weight gain. Stock up on the seasonal fruit in summer, but don't shy away from grabbing the frozen variety once colder temps hit — fruit is frozen at its nutrient peak, so you'll still nab most of the same health benefits.
We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.
Good news for carb lovers: Scientists discovered an easy way to slim down any bowl of rice by as much as 60 percent! And the best part is that you don’t need a fancy lab or a PhD. to make the slimmed-down dish. Here’s how to whip it up: Add a teaspoon of coconut oil and a half cup of non-fortified white rice to a pot of boiling water. Cook it for about 40 minutes, stick it in the refrigerator for 12 hours and enjoy the rice either cold or reheated. How does such a simple cooking hack—that adds fat, no less—slash calories? When the rice begins to cool, its glucose molecules form tight bonds called “resistant starch.” This type of starch, as the name implies, is resistant to digestion, meaning that the body is not able to absorb as many calories or as much of the glucose (a nutrient that’s stored as fat if it’s not burned off) from each molecule. While you may be hesitant to add the oft-vilified oil to your pot, it actually plays an integral role in the process. As the rice cooks, the fat molecules find their way into the rice and act as an additional digestion barrier. Best of all, the research team found that reheating the rice didn’t change the levels of resistant starch (as it does with pasta and potatoes), deeming this calorie-slashing cooking hack safe for leftovers, too.
Though you may think skipping a meal such as breakfast will help you lose weight because you would be consuming fewer calories, numerous studies have actually shown that bailing on breakfast is bad for your waistline. Why, you ask? It turns out that skipping breakfast not only means you’ll likely consume more calories later in the day, but eating more calories in the later part of the day is a nightmare for metabolic circadian rhythms, which help keep your weight in check.
Instead of gobbling down breakfast at home, eat at your desk a few hours later than you typically do. Pushing back your first meal of the day naturally reduces your “eating window”—the number of hours you spend each day grazing. Why’s that beneficial? Sticking to a smaller eating window may help you lose weight, even if you eat more food throughout the day, a study published in the journal Cell Metabolism found. What’s more, time-restricted eating reduced excessive body weight by 20 percent and prevented further weight gain.
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
We know you love binge-watching your favorite reality series, but it’s important to enjoy your meals sitting at your kitchen table—not in front of the television. Why? Carolyn Brown, MS, RD, of Foodtrainers, told us that in addition to commercials of unhealthy food and drinks increasing our cravings, TV is so distracting that it makes it harder to realize when we’re actually satiated. Science agrees with Brown: A study in the American Journal of Clinical Nutrition found that paying attention while eating can aid weight loss efforts while distracted eating can lead to a long-term increase in food consumption.
