While you may think you’re doing yourself and your waistline a favor by stocking up on sugar-free goodies, the well-meaning habit is likely doing more harm than good. In a 2012 study in The American Journal of Clinical Nutrition, researchers found that those who drank diet beverages had higher fasting glucose, thicker waists, lower HDL (good) cholesterol, higher triglycerides, and higher blood pressure. In other words, sugar-free cookies, soda, and the like may seem like the healthier option, but they contribute to a bulging belly and negatively impact your health in multiple ways.
Calcium and vitamin C team up well to boost metabolism, and broccoli is just one of several healthy foods that contains both nutrients. What sets broccoli apart from the others, however, is that the green veggie also contains kind of fiber that’s been shown to increase the digestion, absorption and storage of food, also known as the thermic effect of food (TEF). A revved up metabolism combined with an increased TEF is a match made in weight loss heaven, so consider incorporating broccoli into a tasty stir-fry, or serving it as its own side dish.

A myriad of different teas have been shown to aid weight loss, and green tea is no exception. In fact, a study published in The Journal of Nutrition found that after just two weeks, those who sipped four to five cups of the green brew each day, in addition to working out for 25 minutes, lost more belly fat than those who didn’t imbibe. Scientists attribute green tea’s ability to shrink waists to the beverages catechins, a type of antioxidant that hinders the storage of belly fat and facilitates rapid weight loss.
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.
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.

Based on my experience in nutrition counseling, most of us tend to snack on foods that aren’t nutrient-dense, but are high in calories. For example, skipping sugary beverages is often the easiest way to lose weight faster. You don’t feel full from drinks — even the ones that do contain calories — so swapping those out for sparkling water or unsweetened tea and coffee is the best place to start. Other major culprits often come in refined grains like cereals, chips, crackers, and cookies.
Even if you’re trying to reduce your eating window, you shouldn’t go to sleep starving. In fact, going to bed with a rumbling stomach can make it more difficult to fall asleep and subsequently leave you feeling ravenous the next day. And get this: Eating the right type of bedtime snack can actually boost your metabolism and aid weight loss, registered dietitian Cassie Bjork explained. “The right snack can help keep blood sugar stable so the fat-burning hormone glucagon can do its job. I suggest pairing a natural carb with a healthy fat. Apple slices and almond butter, berries with heavy cream and carrots with guacamole all fit the bill.”
Finally decided to venture out for a run? Snack on some beets before you hit the pavement. A study published in the Journal of the Academy of Nutrition and Dietetics  found that runners who ate baked beets before a 5K race ran 5 percent faster. Researchers suspect this is because beets are high in nitrates, a natural chemical that increases endurance and lowers blood pressure.
“Calorie counting is not the only game in town when it comes to weight loss. Chemical counting should also be part of our decision-making process. Processed foods, plastic bottles, lotions, non-organic dairy, and many other items in our daily lives contain endocrine disruptors that can lead to hormonal imbalance and stubborn weight gain,” Jennifer Cassetta, clinical nutritionist, personal trainer, and expert from ABC’s “My Diet Is Better Than Yours” tells us in 22 Top Weight Loss Tips, According to Nutritionists.
“I wish people knew that gluten-free foods aren’t all automatically healthy,” Torey Armul, MS, RD, CSSD, LDN, spokesperson for the Academy of Nutrition and Dietetics tells us in 22 Top Weight Loss Tips, According to Nutritionists. “People often lose weight and feel better on a gluten-free diet, but it’s usually not because of lack of gluten. It’s because they’re paying attention to their food choices and eating more real foods and less simple carbs. Gluten-free labeled packaged foods actually tend to have more calories and extra fat or sugar for added flavor.”
We’ve been clear on the benefits of wild salmon, but those pink creatures are quite literally not the only fish in the sea. Generally speaking, fish provide one of the best sources of fatty acids known as omega-3s, which will help fend off waist-widening inflammation and are an excellent source of high-quality, lean protein. This allows them to help you maintain muscle mass, thus reducing excess fat accumulation. Some of our favorite healthy seafood include mussels, Atlantic mackerel, and bluefish, but be sure to educate yourself on the ocean dwellers with this list of Every Popular Fish—Ranked for Nutritional Benefits!
Similar to Greek yogurt, a study from Nutrition Research showed that eating eggs for breakfast can make you feel more full and help you eat fewer calories throughout the day, meaning they’re quite the secret weapon for weight loss. Nutritionally speaking, one large hard-boiled egg (about 50 grams) contains less than one gram of carbs and remains an excellent source of protein. Eggs are also loaded with amino acids, antioxidants, and healthy fats.
Weight loss ultimately comes back to the concept of calories in, calories out: Eat less than you burn and you’ll lose weight. And while it’s possible to lose water weight quickly on a low-carb diet, I certainly wouldn’t advocate for it. The diet itself can trick you into thinking that this eating style is working — when really, you might gain back what you lost as soon as you eat carbs again. That can feel incredibly dispiriting if you want results that last longer than a week.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.

Common sense states if you want to lose weight, then you shouldn’t have a large meal not long before going to bed. And now we have additional research to back up that hypothesis. A study published in the journal Obesity followed two groups of overweight women with metabolic syndrome on identical 1,400-calorie weight loss diets for three months. While both groups consumed 500 calories at lunch, one group consumed 700 calories for breakfast and a 200-calorie dinner (the “big breakfast” group), while the other group ate 200 calories at breakfast and 700 calories at dinner (the “big dinner” group). Even though the nutrient content of the meals was exactly the same for both groups, after three months the big breakfast group lost about two and a half times more weight than big dinner group.
We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink just isn't as satisfying as eating a bowl of veggie- and protein-packed stir-fry. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.)
Spirulina is a high-protein seaweed supplement that’s typically dried and sold in powdered form. The dried stuff is about 60 percent protein, and, like quinoa, it’s a complete protein—deeming it a great weight loss tool. A tablespoon of the blue-green algae delivers 8 grams of metabolism-boosting protein for just 43 calories, plus half a day’s allotment of vitamin B12, which can encourage weight loss by giving you more energy and boosting your metabolism. Try tossing some spirulina into a smoothie and watch the pounds melt off.

Out of sight, out of mouth? Simply reorganizing your pantry staples could translate into serious calorie savings. A study published in the Journal of Marketing found that people are more likely to overeat small treats from transparent packages than from opaque ones. For this reason, many nutritionists suggest keeping indulgent foods in the pantry on a high shelf so that you’re less apt to mindlessly grab them.
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.
When grabbing grub at a fast-food restaurant, the “combo” or “value meals” are typically less expensive and make you feel like you’re getting a better deal, but oftentimes they’re also nutritional nightmares. A study in the Journal of Public Policy & Marketing  shows that compared to ordering à la carte, you pick up a hundred or more extra calories by opting for the aforementioned cheap “value meals.” That’s because, when you order items bundled together, you’re likely to buy more food than you need or want, and end up overeating as a result. To keep your weight in check, order your food piecemeal instead.
Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.
According to a study published in Bioscience, Biotechnology, & Biochemistry , consuming apple cider vinegar each day can lead to weight loss, reduced belly fat, waist circumference, and lower blood triglycerides. More specifically, the study of obese Japanese participants found that those who consumed just one tablespoon of ACV over a three-month period lost 2.6 pounds, and those who consumed 2 tablespoons lost 3.7 pounds in the same time frame. Go ahead and toss a tablespoon or two of this calorie, fat, and sugar-free stuff in your next salad dressing, sauce, or smoothie.

If you have a big celebration or date coming up, you might think it makes sense to “save” your calories for when it’s time to let loose, but this technique is rarely effective and could actually be hindering your ability to lose weight. “Although this makes sense in theory—consuming fewer calories total per day—it rarely works out as cleanly as we like,” Lisa Hayim spelled out for us in The 30 Worst Diet Mistakes You’re Making. “By the time you get to the date, and have a drink or two, the feelings of extreme hunger rush in, and you’re grabbing for whatever you can get your hands on, which is usually foods high in calories and fat. You’re so hungry, you may even end up consuming more than a day’s worth of calories in one sitting! Plus, with alcohol in your system, your body is less able to efficiently metabolize the calories,” explains Hayim. “Instead, consume normal meals throughout the day, arrive at your date cool, calm, and collected, and enjoy your cocktail and eat responsibly.”
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.
