You can avoid a mindless binge by adding visual traffic lights to your snack. Researchers at the University of Pennsylvania and Cornell University gave one set of students a bowl of uniform yellow chips, while another group had their regular snack layered with differently colored chips. Students who had their snack segmented ate 50 percent less than those with a uniform bowl.
_{Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.}
Yes, you can eat dark chocolate to lose weight. A study among women with normal weight obesity (or “skinny fat syndrome”) who ate a Mediterranean diet that included two servings of dark chocolate per day showed a substantial reduction in waist size than when on a cocoa-free meal plan. Researchers attribute dark chocolate’s weight loss abilities to flavonoids, heart-healthy compounds in the sweet treat that the scientists at Harvard say can reduce the risk of diabetes, heart disease, and mortality. Like nuts, dark chocolate has also been found to induce satiety. When reaching for chocolate, just make sure you choose a bar with at least 70 percent cacao. Anything less contains more belly-bloating sugar and a significantly reduced flavonoid content.
High-intensity interval training (HIIT) is a great belly-blasting option for those who already feel comfortable in the gym because it helps you drop fatty tissue and build muscle simultaneously. “High-intensity interval training is when you perform an exercise at or close to your maximum ability for a short period of time and then take a brief respite and do it again. HIIT should usually be done on a 2:1 interval, meaning if you did an exercise for one minute, you rest for 30 seconds and then repeat,” explains Dr. Alex Tauberg, DC, CSCS, EMR in 50 Ways to Shrink Your Belly. To use HIIT to shrink your belly, do workouts that engage your core such as abdominal crunches or bridges. “By performing core workouts using a HIIT plan, you can burn calories and build muscle at the same time,” Alex adds. “This can be a great way to flatten that stomach when you don’t have too much time to work out.”
Believe it or not, weight loss isn’t just about exercising and eating right; research suggests what motivates you to get in shape can play a role in your success. A 2014 study in the journal Body Image looked at 321 college-age women and found that long-term, those who exercised primarily for appearance-based reasons had a harder time sticking to their fitness plans than those who worked out to maintain their health. In other words, stop envying those fit models on Instagram and instead remember that you and your loved ones are the people who really benefit when you slim down.

How would you like to take all the great weight-loss results you’ve just read about—and double them? That’s what happens when you supplement your diet with a combination of vitamin D and calcium, according to a Nutrition Journal study. Just four weeks into the 12-week experiment, subjects who had taken these two nutrients—found in abundance in some yogurts—lost two times more fat than the other group! To get similar results at home, start your day with one of these best yogurts for weight loss.

Big-box stores such as Costco or Sam’s Club are great money-savers, but frequenting them to buy groceries can be bad news for your fitness goals. That’s because a 2015 study in the journal Appetite  found that the larger the bottle, bag, or box the food comes in, the larger we think the serving size should be. To come to that conclusion, researchers surveyed more than thirteen thousand people and found that when confronted with larger packages of cola, chips, chocolate, or lasagna, the shoppers tended to want to serve themselves larger portions.
^{Although they're best known for containing potassium, bananas are also a great source of resistant starch, a type of starch that's important for weight loss. Your body digests resistant starch slowly—helping you feel full for longer—while simultaneously encouraging your liver to switch to fat-burning mode. And no need to wait for them to become completely ripe; bananas actually contain more of this calorie-torching ingredient when they're still a little green.
There’s some truth to the old adage that breakfast is the “most important meal of the day,” and if you’re looking to blast belly fat, what you eat at the start of each day can make all the difference. According to a study from the University of Missouri-Columbia, a high-fiber, high-protein breakfast may be the most important investment you can make for your waistline. The study showed that eating breakfast triggered women’s brains to release dopamine, a feel-good chemical that helps to control impulses. In other words, eating a balanced breakfast decreases your chances of reaching for that 3 p.m. candy bar and keeps your belly slim.}

_{A squeeze of lemon adds instant freshness to everything from drinks to salads to fish without additional calories, making it an ideal way to flavor food if you're watching your weight. Plus, the pectin fiber in lemons can help fill you up and fight off hunger cravings. And while it hasn't been scientifically proven, some experts believe that the citrus fruit can aid in weight loss, as well.}
Instead of dragging yourself to the coffee pot when your alarm goes off, open all the blinds! A study in PLoS One found that when obese women were exposed to at least 45 minutes of morning light (between 6–9 am) for 3 weeks, it resulted in reduced body fat and appetite. Researchers think it’s because the morning sun helps synchronize your metabolism to burn fat more efficiently. For more easy ways to burn more calories, check out these 55 Best-Ever Ways to Boost Your Metabolism.

Portions, my friend, portions. You can’t even think of losing weight if you don’t let go of your large plate. It’s plain common sense – reducing the size of your plate means eating less, and eating less means fewer calories. Usually, when we are dining, we tend to eat more than what is required – a terrible habit most of us have unknowingly cultivated. Cut the portions in half and ensure you are choosing smaller portions. A study conducted at The Pennsylvania State University talks about research that has shown the relation between large portions and obesity. It also says that for weight management, you can eat larger portions of low-energy-dense foods (2).

Speaking of flavonoids, the waist-whittling compounds also exist in higher concentrations in red fruits such as watermelon, Pink Lady apples, and plums, meaning they also have the power to induce weight loss. In fact, a 2016 study in the journal BMJ found that people who eat a diet rich in flavonoid-heavy food tend to gain less weight, which could be promising seeing as many people tend to put on pounds as they age. In addition, anthocyanin, a specific flavonoid compound that gives red fruits their color, has been shown to reduce fat-storage genes.
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.

When many of us have too many options to choose from, we often become flustered and make the wrong decision. Same goes for food. If you have a few different boxes of cereal and a handful of flavors of potato chips, you’re likely to eat more of the packaged stuff. Limiting your options to just one can cut down on your grazing habits and prevent a snack attack.

Water is a weight loss ally in a number of ways. For starters, if sipped prior to a meal it can help ensure you eat less. A British study published in the journal Obesity that asked participants to chug 16 ounces of H2O prior to eating found said participants lost an average of 2.87 pounds in 90 days—which translates to nearly 12 pounds in a year! Water helps you blast even more fat because it is a much better beverage choice than diet soda or fruit juice, both of which are full of artificial sweeteners that can pack on belly fat super fast.
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.
Though you may give yourself a pat on the back for passing on that slice of chocolate cake you’ve been craving for dessert, you’re actually doing yourself (and your waistline) a disservice in the long run. According to a study in the International Journal of Eating Disorders, when you resist food, your body actually experiences more cravings for whatever it is you aren’t getting. Saying “no” to a sweet treat or slice of pizza wires our brains to view forbidden foods as rewards, setting us up for cravings that are hard to satisfy, so give yourself a break and indulge every now and again.
