Potatoes often get a bad rap, but when it comes to weight loss they're hard-to-beat sources of scale-dropping fiber. According to the Cleveland Clinic, sweet potatoes will up the insoluble fiber in your diet, keep you full longer, and you can bake and eat one for just 114 calories. Just watch what you load it with — instead of cheese or sour cream, opt for good-for-you fillings like black beans, tomatoes, and bell peppers.

Is your obsession with Reese’s and Pringles derailing your weight loss efforts? It might be if you’re not using the self-checkout kiosks at the grocery store. Let us explain: According to a study by IHL Consulting Group, impulse purchases dipped 32.1 percent for women and 16.7 percent for men when they scanned their items and swiped their credit card on their own. Although not all impulse buys are bad for your belly, a whopping 80 percent of candy and 61 percent of salty-snack purchases are unplanned.
You may think hand sanitizer will zap germs and prevent you from getting sick, but it could also be making you fat. The germ-killing substance contains triclosan, which researchers have found to be an “obesogen,” meaning it could cause weight gain by disrupting your body’s hormones. A study published in the journal PLOS One found that people who had detectable levels of triclosan in their bodies were associated with a 0.9-point increase in their BMIs. Word to the wise for germaphobes looking to lose weight: Rely on good ol’ soap and water instead.

In a study of a group of obese young women, those who started the day with 35 grams of protein -- that’s probably way more than you’re eating -- felt fuller right away. The women ate a 350-calorie breakfast that included eggs and a beef sausage patty. The effect of the high-protein breakfast seemed to last into the evening, when the women munched less on fatty, sugary goods than the women who had cereal for breakfast.

While we’re on the subject of water, why not throw a few lemon slices into the hydrating and satiating beverage? In addition to adding a pop of color and flavor to a tall glass of H2O, lemon can also help encourage weight loss. Just one of the bright citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of a stress hormone called cortisol that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain.
A recent JAMA Internal Medicine study of nearly 4,000 couples found that people are more likely to stick to healthy habits when they team up with a partner. Invite your honey to a Saturday morning run and then hit the showers together—knowing you have something steamy to look forward to afterward should serve as some additional motivation. And then follow up your workout with some of the best proteins for your penis.
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.
If you just can’t shake those belly-bloating sugar cravings, try tyrosine—a building block of protein. It has been shown to prevent that yearning for the sweet stuff by encouraging the brain to release dopamine and another neurotransmitter, norepinephrine. In other words, eating more tyrosine (which can be found in eggs, spirulina, certain cheeses such as Parmesan, Gruyère, Swiss, and Romano, milk, sesame seeds, beef, and bacon) helps fend off those harmful sugar cravings that make your belly fat.
Who knew that fantasizing about eating your favorite candy can actually result in real-life weight loss? A study found that daydreaming about eating an entire packet of the sweet stuff before indulging may cause you to eat less of it. To come to this finding, researchers asked participants to imagine eating three M&Ms versus 30. Then, they conducted a taste test where participants were able to nosh on the chocolate orbs. The results? Those who imagined eating lots of M&Ms ended up gobbling down the least!

Leaving the comforts of your gym can be difficult, but outdoor workouts have their own unique set of benefits. Research has shown that breaking a sweat outdoors may be more beneficial than burning calories inside. According to a study published in Environmental Science and Technology , exercising in a natural environment outdoors may improve energy levels and decrease stress more than working out indoors can.

There’s no denying dinner rolls are delicious, but you don’t need to take the “breaking bread” aspect of a meal so literally. Instead, steer clear of the bread basket and munch on a leafy green salad instead. If the carb-heavy starter is still too tempting to avoid, try nibbling on a high-fiber snack before sitting down to eat, such as a handful of nuts. The fiber found in nuts will keep you satiated, meaning you won’t be as easily induced to reach for the bread and butter, and you’ll be swapping out unhealthy fats for healthy ones. It’s a win-win!

Alcohol isn’t exactly a weight loss ally, but using it to flavor meat when you cook it could help you drop a few pounds and stay healthy. According to a study in the Journal of Agricultural and Food Chemistry , if you marinate meat with beer for four hours, you can lower the harmful chemicals it produces when exposed to high heat by up to 68 percent.

A Credit Suisse Research Institute report found that more and more of us are choosing full-fat foods over skim, light, fat-free, or other modern monikers of leanness. And while many health organizations like the American Heart Association still recommend cutting down on fat—particularly saturated fat—this full-fat trend may be a healthy rebellion against those decades-old credos, according to recent studies. In fact, people who eat a lot of high-fat dairy products actually have the lowest incidence of diabetes, according to a 2015 study of 26,930 people in the American Journal of Clinical Nutrition. Those who ate a lot of low-fat dairy products, on the other hand, had the highest incidence. So what’s the best way to join the full-fat revolution? Eat This, Not That! polled some of the country’s top nutrition experts and asked for their favorite full-fat fat burners. Check out what they said in our exclusive report the 20 best full-fat foods for weight loss.

Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish.
^{Losing weight isn't all about exercise – what you eat matters too. But nobody wants to eat diet food that makes them feel like they're going to gnaw their arm off before dinner. That's why registered dietitians say it's important to up your intake of veggies, grains, nuts, and other foods that are full of fiber, protein, and other pound-dropping nutrients. These options will help you prevent cravings and keep you full straight through your usual afternoon snack.}
Healthy midnight snacks are OK, but try not to graze in the window of time between breakfast and lunch. A study published in the Journal of the American Dietetic Association found mid-morning snackers typically eat more over the course of a day than afternoon snackers. Furthermore, researchers found that dieters with the mid-morning munchies lost an average of 7 percent of their total body weight while those who did not snack before lunch lost more than 11 percent of their body weight.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
Yogurt is protein-packed and full of probiotics, which are good for gut health and may help your weight-loss efforts. Your gut health can impact your weight, and eating more fiber and probiotics helps keep your gut bacteria happy, which can be good for your metabolism (read more about your gut-weight connection). Go Greek for more protein; plus, research from Appetite found that consumption of Greek yogurt was associated with reduced appetite and increased satiety. Just keep an eye on added sugars in flavored yogurts, which only add calories. Instead, use fresh fruit to sweeten plain yogurt.
