If you feel like you're trying your hardest but the numbers on the scale are climbing, these could be the reasons you're tripping up.

Avoid the obvious problems

Everyone knows that if you’re a drive-through regular and routinely polish off pints of ice cream you’re going to gain weight, but that’s not you. In fact, you rarely eat fried foods, and when you do eat dessert you limit yourself to a sensible portion. So why are your pants suddenly getting tighter?

The reasons why the pounds are piling on aren’t always quite as obvious as you might expect them to be. Here are 50 sneaky things you might not have considered that could be making you gain weight.

Whole grains cover your whole plate

Sure, they’re healthy—especially compared to refined grains. But you can have way too much of a good thing. “The 2015 Dietary Guidelines for Americans recommend you make half your grains whole, so ingredients such as whole wheat pasta, brown rice, and quinoa can all be part of meeting these recommendations. But these whole grains also contain a hefty number of calories if you eat too much,” says Toby Amidor, RDN, author of The Easy 5-Ingredient Healthy Cookbook. Two cups of cooked whole-wheat pasta, for instance, adds up to 400 calories. Try to limit yourself to a 1-cup serving (same goes for brown rice, quinoa, farro, and barley) and round out your meal with plenty of veggies and some lean protein. By the way, here are 50 things doctors wish you knew about losing weight.

You’re obsessed with avocado toast

Again, it’s about the quantity, and it’s easy to overdo it. “Avocados contain a healthy dose of nutrients and heart-healthy unsaturated fat, but eating an entire avocado or using half an avocado daily for your avo toast can rack up hundreds of calories rather quickly,” says Amidor. “An entire avocado contains 322 calories and close to 30 grams of fat—that’s 45 percent of the daily recommended amount of total fat!” About a fifth of an avocado is the right amount for a healthy snack.

You trust in the broken cookie rule

Wouldn’t it be nice if those cookie crumbs at the bottom of the bag and the fries you swiped from a friend’s plate didn’t contribute to your calorie count for the day? Sadly, those nibbles add up. “It’s easy to get 100 calories—or more!—from little bites each day, which could cause you to gain roughly a pound a month without realizing where the extra calories are coming from,” says Tammy Lakatos Shames, RDN, CDN, CFT, co-founder of NutritionTwins.com. Try keeping a food diary for a few days and write down everything you put in your mouth; the tally might surprise you.

You tell your waiter to “go light” on the butter

You get an “A” for effort, but “light” probably doesn’t mean the same to you as it does to most professional chefs. If they’re following instructions they will scale back a bit, but they’re probably still going to slather on way more butter—or mayo or aioli or other high-calorie ingredients—than you would if you were preparing a meal at home, says Lakatos Shames. “Instead, request the condiments/sauces/butter/oil on the side and use them sparingly, if at all.”

You eat straight from the bag

You take just one small handful of chips… and then another, and maybe another. How much are you really eating in total? “It’s easy to go back for more and assume you just had a serving,” especially when eating out of a “family size” bag, says Lakatos Shames. (The bigger the bag, the more people tend to eat.) Next time, take a minute to grab a small bowl and measure out a reasonable portion first.

“Juice-based drinks and smoothies often contribute a lot of calories,” says Ginger Hultin, RDN, a spokesperson for the Academy of Nutrition and Dietetics. “They can spike blood sugar quickly, which causes it to drop back down and makes you ‘crash’ once insulin responds. Once blood sugar is down again, the body starts craving more sugar—and that’s what fruit juice and fruit smoothies are, really.”

You like to unwind with an adult beverage

You probably know that margaritas, daiquiris, and other calorie-laden mixed drinks can make you gain weight, “but even having low-calorie beer and wine can add up quickly and cause weight gain,” says Hultin. “Some people have a hard time with weight loss if they’re drinking much at all.” Don’t miss these surprising causes of weight gain that aren’t food.

You’re nuts for nuts

Nuts have a healthy reputation, which is mostly deserved. “They’re packed with vitamins, minerals, antioxidants, fiber, protein, and healthy fats,” says Hultin. The catch is that the serving size is probably much smaller than you realize. “For example, 14 shelled walnut halves and 24 shelled almonds equal one serving,” she notes. Be sure to count them out (or buy prepackaged 100 calorie packs) instead of eating by the handful.

You don’t focus on your food

Whether you’re at a cocktail party, sitting in front of your computer, or binge-watching a show on Hulu, food isn’t your focus—yet you’re still eating. And eating. And eating. “When we’re not being mindful or paying attention, it’s easy to eat more than we want—or need—to be eating” and gain weight, says South Florida sports nutritionist Barbara Lewin, RDN. Try eating more slowly and mindfully and you’ll naturally eat less.

You fail to plan

It’s 6 p.m. You’re hungry. What’s in your fridge? If the answer is nothing but ketchup packets and expired yogurt, it’s only a matter of minutes before you call for takeout. “It’s important to create an environment for success,” says Marisa Moore, MBA, RDN. “Stock the fridge and pantry with the foods you like that are healthy and keep you feeling full and satisfied.”

You’re so, so tired

“Not sleeping enough can certainly contribute to weight gain, because it can make you crave high carbohydrate/high fat comfort-type foods,” says Elisa Zied, CDN, author of Younger Next Week. While research has shown that sleep deprivation can mess with your hunger hormones throughout the day, you may be especially vulnerable late at night when you’re less active and trying to de-stress and unwind, she adds. Learn about the nighttime habits that lead to weight gain.

You OD on oil

Sautéing your own fish and veggies? Great! Pouring carelessly from a big bottle of oil? Not so much. “We use way more oil when cooking than we think, and every tablespoon adds 120 calories,” says Joy Bauer, RDN, Founder of Nourish Snacks, host of NBC’s new show, “Health + Happiness,” and the nutrition expert for the TODAY Show. “Instead of pouring freehand from the bottle when sauteing, roasting, or grilling, try an oil mister—you’ll use far less. Store-bought spray canisters are super convenient, but you can also make your own more Earth-friendly version by purchasing a mister at a home-goods store and refilling it with a heart-healthy oil like olive or canola.”

You live in a smoggy city

It’s not only bad for your lungs; the congestion could also be making you gain weight. Believe it or not, a number of studies have tied pollution to a higher risk of obesity. While some of these studies have been limited to animals, such as rats, a 2016 analysis published in Obesity Reviews suggests that the connection extends to people. More research is needed, but exposure to a variety of chemicals that impact the endocrine system may be to blame. If you can’t move, you may at least want to consider investing in an air purifier.

You’ve messed up your taste buds

We all have different preferences, but research shows that when you start to overeat certain foods and gain weight your taste buds can become a bit duller. The result: Flavors like sweet and salty don’t taste as intense, so you may require more sugar and salt to get the taste you crave. Try scaling back slowly—one fewer sugar packet in your coffee—or simply wait it out; your taste buds will acclimate over time. Don’t miss these bizarre things that happen to your body when you gain weight.

You indulge in fat-free cookies, bars, and other diet goodies

Nothing’s really for free, is it? Fat-free treats are usually packed with extra sugar, which can make the calorie count soar (and you gain weight), says Sonya Angelone, RDN, a spokesperson for the Academy of Nutrition and Dietetics. You might be better off with a small portion of the real stuff. Fat-free junk is also one of the 10 worst foods for your digestion.

You dip bread in olive oil instead of spreading on butter

“Oil is higher in calories than butter, and it gets soaked up by the bread quickly,” says Angelone. The health halo is a factor, too. “People usually eat more calories from oil than from butter because ‘it’s healthier.'”

You’ve switched to gummy vitamins

It’s true that they don’t have a lot of calories, but they have more than plain old-fashioned pills. “They’re full of sugar calories, especially if you eat a few too many. That can add weight slowly but surely,” says Angelone. Here are some of the signs your weight gain means trouble.

You dip raw veggies in ranch

Veggies are great. The ranch dressing, however, has a lot of calories from fat, and it’s so easy to keep dipping and dipping, says Angelone. Measure out a small serving of dressing or switch to a lighter topping, like hummus (which also packs some protein and fiber).

You finish your kids’ leftovers

“These are considered seconds!” says Angelone. Or, if you have a full house, thirds, fourths, and so on. Those calories still count—pack the food away for leftovers or toss it.

You drink green juices

If it’s all (or mostly) veggies, then you’re probably fine. But many “green” juices actually have apple juice as a first ingredient, says Angelone. “This is really a drink full of sugar calories.”

You have PCOS

About one in five women have polycystic ovary syndrome (PCOS), but unless you’ve been struggling to get pregnant you might not even know that you’re one of them. This hormonal disorder often goes hand-in-hand with infertility as well as obesity, acne, and excess body hair. If you have any of these symptoms and your periods are irregular (and you’re not approaching menopause), talk to your gynecologist about getting screened. Here’s how to lose weight if you have PCOS.

You reward exercise with a “healthy” treat

Exercising—whether you’re trying to lose weight or not—is a great move. But rewarding the effort with food is a different story, says Karen Collins, RDN. A muffin, for instance, can have around 400 calories! “It’s very easy for a reward to contain more calories than you used up during the added activity. Over time, this will lead to weight gain,” she says. “The answer is not to forego the exercise; the answer is to retrain yourself to see the walk/activity as the reward.” If that’s too difficult at first, at least opt for non-food rewards (like a pedicure or new book download). Here’s why exercising too much can actually lead to weight gain, too.

There’s too much variety in your diet

Variety may be the spice of life, but too many options might prompt you to overindulge. “Sometimes getting too much food variety can make it more challenging to curb calories,” says Jackie Newgent, RDN, private cooking coach and author of The All-Natural Diabetes Cookbook. No, you don’t have to eat the same exact thing every single day, but if you can standardize something—perhaps breakfast or your afternoon snack—it might make it easier to avoid overeating. And definitely steer clear of buffets!

You fall for fads

Who doesn’t want a quick fix? The problem is that a short-term solution—think a lemonade/cayenne cleanse or grapefruit diet—is unlikely to yield lasting results. “You may lose 5 to 10 percent of your body weight, but once you go off your diet you’ll gain the weight back plus more,” says Toby Smithson RDN, author of Diabetes Meal Planning and Nutrition for Dummies.

You’ve gone too low carb

Carb cutting may be trendy, and it works—to a certain extent. “If you aren’t eating carbs or are eating a diet very low in carbs, most likely you will be filling your plate with protein and fats. But the calories from too much protein or fat can also lead to weight gain,” says Smithson.

Unless you’re using these to replace a meal, watch out. “Most contain 200-250 calories, which is way more than is needed as a snack,” says Rachele Dependahl, RDN, CDE, a dietitian and certified diabetes educator at Cedars-Sinai in Los Angeles.

You always go for the entree salad

Don’t assume it’s the lighter option. “Salads with toppings like avocado, shredded cheese, nuts, and dressing can easily add up to more than 1,000 calories!” says Dependahl. Pay close attention to all the details and then order accordingly.

You nosh on veggie chips

Despite the misleading name, there isn’t a heck of a lot of veggies in these with the exception of processed potatoes—which means they’re not that much better for you than regular potato chips. “A small serving, like 12 veggie chips, might contain up to 160 calories,” says Dependahl. And who only eats 12?Watch out for these other 17 “healthy” foods you might want to avoid.

If you keep dipping and dipping, you’re going to gain weight. “Two tablespoons of peanut butter contain 220 calories, and when you’re dipping apple slices or celery it adds up fast,” says Dependahl.

Your thyroid is out of whack

If you’ve suddenly added an extra five to ten pounds and you also have symptoms such as fatigue, dry skin, and constipation, the butterfly-shaped gland in your neck could be to blame. See your internist or an endocrinologist to get your thyroid hormone levels checked.

You love a good deal

If you’re a regular at Costco or Sam’s Club, we get it. But filling your cart with inexpensive food that comes in super-size packages might very well be what’s driving your recent weight gain. In fact, research has shown that the explosion of big-box stores is a contributing factor to the rising trends in obesity across the country.

You laser in on one nutrient

“Whether it’s sugar, carbs, or fat, it’s easy to get overly focused on reducing one nutrient,” says Karen Ansel, RDN. “The truth is our bodies need a mix of carbs, protein, and fat to function properly, which is why nature included all of these in food. In my experience, eating a healthy mix of all of these is the best way to satisfy your appetite and boost your energy at the same time.”

You graze all day

Think eating mini-meals will help you slim down? Not so, says Ansel. “When we’re always eating it’s really easy to put more calories in our mouths than we realize. Plus nibbling your way through the day never gives you that feeling of fullness you’d get from a real meal, so you always feel a little hungry.” Her advice: Shoot for three real meals and one small snack per day.

Your idea of a proper portion is way off

Just because your cereal bowl fits 16 ounces doesn’t mean that’s what a single serving looks like. Oversized plates and wine glasses can cause similar confusion. “While there are lots of factors that help with weight loss, eating less overall is definitely a biggie,” says Ansel. “Think of it as simple math. If you were to shrink your portions by 10 percent by leaving over a few bites at every meal, you’d eat 10 percent fewer calories, which can add up to significant savings.” These portion-control tricks will help you avoid overeating.

You live at sea level

There may not be much you can do about this, but research shows that people who live at higher altitudes tend to be thinner. They also have a lower incidence of type 2 diabetes. Why this is the case isn’t entirely clear, but researchers at Cedars-Sinai have suggested that atmospheric pressure, radiation levels, and other environmental issues may all factor in.

The research here is a bit mixed—after all, it is calorie-free!—but a growing body of evidence suggests that people who regularly sip artificially-sweetened drinks are more apt to be obese and put on weight over time.

You trust too much in your willpower

If you think you can simply will yourself to pass up the donuts at your Monday meeting, you might be fooling yourself. If you want to lose weight or avoid gaining it, you need to set up your kitchen, office, and even your car for success by keeping healthy alternatives on hand. “Relying on education, willpower, and ‘mindfulness’ to be the main mechanisms to healthier eating leads people to Einstein’s definition of insanity,” says Tom Rifai, MD, founder of Elite Health Coaching and Reality Meets Science. A better bet: Look ahead, spot the pitfalls, and plan ahead so you can dodge them.

Calorie counting and food with labels conceptudra11/Shutterstock

You focus on calories, but not calorie density

One tiny box of raisins has about 130 calories, which isn’t bad—but you could eat an entire cup of grapes for even less than that. “To feel comfortably full on fewer calories, you need to choose foods that are high in water and fiber,” says Dr. Rifai. Add some foods that have a lot of water and protein (like low-fat yogurt and egg whites) to your mix and you’ll be able to eat less without your tummy rumbling.

You eat too lightly during the day

“Many people believe it’s a good idea to ‘eat lightly’—basically semi-starve themselves—throughout the day, but that inevitably drives them to overeat in the evening,” says Dr. Rifai. Instead, he suggests a “don’t stuff, don’t starve” approach: Eat at the earliest signs of hunger and stop when you’re just slightly full.

You only do cardio

Aerobic exercise is key for torching calories, but if you want to keep your metabolism up even while you’re at rest you absolutely have to add in some strength-training. Research has shown that people who do a combo are most likely to lose weight.

You take blood pressure meds or antidepressants

Antidepressants are well-known for causing weight gain, but it’s not unusual to put on a few pounds while taking a beta blocker like metoprolol to control your blood pressure, either. Whatever Rx you’re on, talk to your doctor if you think it’s making you fatter; switching to a different drug might help.

You believe “organic” equals healthy

If you want to steer clear of pesticides and support organic farming practices, that’s great. But research has shown that the word “organic” confers a health halo, even when it’s not deserved. So while you might shun regular Oreos, you have no qualms about putting those chocolate cream-filled organic cookies into your cart (and your mouth), even if the calorie content is exactly the same.

Your house is a mess

Tidy house, tighter body? Research from Duke University suggests that it’s possible. Scientists discovered that the dust found in many homes is packed with hormone-disrupting chemicals that encourage your body to store more fat. Time to start Swiffering a little more often. Here are some other sneaky ways your house is making you gain weight.

You caught this type of cold

A week or so of miserable congestion might just be the beginning of what the common cold can do to your body. A University of California-San Diego study of children found that 80 percent of those who’d been exposed to a particular strain of the cold virus—adenovirus 36—were obese. As strange as this might sound, it doesn’t seem to be a fluke, as other research has also linked this strain with weight gain.

You’re broke

It’s hardly fair, but research confirms that lower-income Americans are much more apt to be obese compared to those who are wealthier. While some issues related to this problem (such as a lack of fresh foods at supermarkets in poor areas) may be out of your hands, it is possible to eat well on a tight budget. Check out how to eat healthily and save money right.

You’re super stressed

Turning to comfort foods is only part of the problem. Chronic stress also taxes your body and contributes to elevated levels of hormones that cause inflammation as well as lead to packing on the pounds. Unless you’re dead, some stress is a given, but finding ways to chill out can make all the difference. Learn more about how weight gain is a sign of stress.

You live way out in the ‘burbs

Is the nearest supermarket three miles away? Do you even have sidewalks? Research shows that suburban sprawl is closely tied to weight gain, probably because you rarely walk and rely on the car for errands and commuting. Even if you feel like you’re constantly rushing around, remember that driving carpool doesn’t translate to burning very many calories. Try wearing a fitness tracker to see how many (or few) steps you’re actually getting throughout the day. Check out the secrets of 18 women who exercise every day.

Your nights are too bright

You may have heard that exposure to artificial light late at night messes with your sleep, but it turns out it also messes with your metabolism, according to research from Northwestern University. The good news: Installing some dimmer switches can help mitigate this problem.

You don’t get enough daylight

The flip side of too much light at night, of course, is too little (natural) light during the daytime. In fact, inadequate exposure to natural sunlight—especially during the fall and winter, when the days are shorter—seems to encourage cells to store more fat. Make an effort to see the sun for at least a few minutes each morning to help keep your body’s rhythms on track.

You’ve recently lost some weight, and your body wants revenge

You managed to shed a few pounds, but they’re creeping back fast because you’re hungrier than ever. What gives? Unfortunately, it’s your body’s way of trying to maintain your fat reserves for a famine that’s most likely never coming. Research shows your appetite really does surge following a loss of body weight, which means it’s all too easy for the pounds to regain the weight. Try drinking extra water and eating plenty of water-rich, low-cal foods until you no longer feel ravenous all the time. Need more help? Check out these 42 fast and easy weight loss tips.
