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.
Making your sandwich with two slices of bread is so last year. Aid your slim down efforts by opting for whole-grain bread over white and preparing your sandwich “open-faced” style—the fancy name for kicking the top piece of bread to the curb. Doing so keeps about 70 to 120 calories off your plate. If losing some bread leaves your tummy rumbling, beef up your meal by munching on a cup of baby carrots or sugar snap peas. These pop-in-your-mouth veggies are loaded with fiber and water, which can help aid satiety and weight loss efforts.
Artichokes are incredibly filling—in fact, they are one of the highest-fiber vegetables, says Sass. A single boiled artichoke contains a whopping 10.3 grams of fiber—almost half the recommended daily amount for women. To curb your appetite before a meal, Sass suggests enjoying the veggie as a pre-dinner appetizer: try them in a refreshing salad with edamame and asparagus, or make homemade salsa with artichoke hearts, tomatoes, olives, and red onions.
Berries are more than just morsels of sweetness that you can toss on yogurt or work into a smoothie; they can help you lose weight, too! Raspberries pack more fiber and liquid than most other fruits, which boosts satiety. They’re a rich source of ketones, antioxidants that can make you slimmer by incinerating stored fat cells. And like other berries, raspberries are loaded with polyphenols, powerful natural chemicals that have been shown to decrease the formation of fat cells and eliminate abdominal fat. Not to be outdone, research suggests blueberries can also help blast away stubborn belly fat by engaging your get-lean genes. After a 90-day trial, University of Michigan researchers discovered rats that were fed a blueberry-enriched diet showed significantly reduced belly fat compared to those who skipped the berries.

In addition to blasting belly fat, you should also be working out and trying to build up your muscle mass. Even when you’re at rest, your body is constantly burning calories, and the “resting metabolic rate” is much higher in people with more muscle. That’s because every pound of muscle uses about six calories a day just to sustain itself. If you can pack on just five pounds of muscle and sustain it, you’ll burn the caloric equivalent of three pounds of fat over the course of a year, and be even closer to obtaining that lean physique you’ve always wanted.
What smells like an exotic vacation and can shrink your waist faster than your favorite Zumba class? You got it: coconut oil. A study of overweight participants published in Pharmacology found that just two tablespoons per day reduced waist circumference. However, the health benefits of coconut oil are still debated—coconut oil is high in saturated fat. But that’s not necessarily a bad thing; it’s in the form of medium chain triglycerides (MCTs), which aren’t processed in the body the same way long-chain triglycerides (LCTs). A study published in the International Journal of Obesity and Related Metabolic Disorders found that when MCTs replaced LCTs in the diets of overweight women, they were less likely to gain weight.
The American Heart Association recommends that the amount of added sugar consumed in a day shouldn’t exceed 25 grams for women and 37.5 grams for men, but since the sweet stuff is in everything from bread to tomato sauce, most Americans aren’t adhering to those guidelines and they’re fatter for it. In a review of 68 clinical trials and studies, New Zealand researchers reported in the British Medical Journal that increasing sugar intake meant increasing body weight while reducing sugar meant reducing body weight. Additional research has shown that cutting back on the granular stuff is one of the fastest ways to lose weight.
As far as grains go, quinoa is a great one to have around if you’re looking to lose weight. It’s packed with protein and fiber, and contains approximately 220 calories per cup, cooked. What’s more? Quinoa is one of the few plant foods that offer a complete set of amino acids, meaning it can be converted directly into muscle by the body. It’s also incredibly versatile, and can be eaten as part of a salad, tossed in a smoothie, or on its own as a side dish.
Dining out can kill your hard-earned weight loss wins—and so can boozing too hard. To stay on track with your better-body goals, order your glass of wine or cocktail near the end of your meal. That way, the sweetness can act as a low-cal dessert. Plus, it won’t lower your inhibitions before your meal, which may prompt you to order something unhealthy off the menu.
Sauces and spreads. Eat lean protein (like chicken, eggs, fish, pork, or lean beef) that is grilled without oil and free of any sauces and spreads. These items boost the calorie intake of your meal by hundreds of calories and often add a lot of salt, which could sabotage your weight-loss plans. Eating your meal without these extras is easier than you would imagine.
Going gluten-free may be a popular trend, but unless you're actually gluten-intolerant or have celiac disease, plenty of reasons exist to continue eating whole grains. They're a tasty way to fill up on both soluble and insoluble fiber, which help you feel full for longer and keep bowel movements regular (oats, barley, and bulgur are especially high sources). Whole grains can also help prevent weight gain: in one study, women who ate whole grains like wheat germ and dark bread had a 49% lower risk of "major" weight gain over time.
Think of each almond as a natural weight-loss pill. A study of overweight and obese adults found that, combined with a calorie-restricted diet, consuming a little more than a quarter cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And after 24 weeks, those who ate the nuts experienced a 62% greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. A study printed in The Journal of the International Society of Sports Nutrition found that almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts.
