Eating Habits to Lose Abdominal Fat As You Age, Say Dietitians

Curb Your Sweet Tooth

Out of sight, out of mouth? Simply reorganizing your pantry's "top hits" could translate into serious sugar savings, according to researchers at Google. The study, dubbed "Project M&M," found that storing chocolate candies in opaque containers as opposed to glass ones help curb M&M consumption by 3.1 million calories in just seven weeks. In the study, they also gave healthier snacks more prominent shelf space. A similar study published in the Journal of Marketing found that people are more likely to overeat small treats from transparent packages than from opaque ones.

Sleep in a Cold Room

Simply blasting the air conditioner or turning down the heat in the winter may help attack belly fat while we sleep, according to a study in the journal Diabetes. As it turns out, colder temps can subtly enhance the effectiveness of your brown fat stores, which keep you warm by helping your burn through belly fat. Participants spent a few weeks sleeping in bedrooms with varying temperatures: a neutral 75 degrees, a cool 66 degrees, and a balmy 81 degrees. After four weeks of sleeping at 66 degrees, the participants had almost doubled their volumes of brown fat.

Increase Your Load

If you can do more than five reps of an exercise, pick up a heavier weight. As you build muscles and your body gets stronger, you can increase your load to challenge your body. It's particularly important to work larger muscle groups, like your glutes, with a heavier weight, as this will burn fat, in the belly.

Ditch Your Night Light

Exposure to light at night doesn't just interrupt your chances of a great night's sleep, it may result in weight gain, according to a study in the American Journal of Epidemiology. Study subjects who slept in the darkest rooms were 21% less likely to be obese than those sleeping in the lightest rooms. For more ways to lose weight, check out these ways to flatten your belly!

Stock Up on Healthy Foods

Brian Wansink, director of the Cornell Food and Brand Lab, found that you can estimate how much someone weighs by taking a photo of their kitchen counter. After analyzing photos of 200 kitchens, he found that women who have soda sitting on their countertops weigh an average 26 pounds more while those who have cookies weigh about eight pounds more. The biggest surprise: Keeping cereal on your counter leads to an additional 20 pounds of body weight. The lesson here is to clean empty calories off your countertops to start losing weight.

Make Fruits and Veggies Accessible

Replace your candy and cookie jars on the kitchen counter with a bowl of fresh fruits and containers of nuts. Stock your fridge with chopped veggies and hummus for a quick and healthy snack. This way they're more readily available, and you have no excuses to grab a bag of chips, right? Katie Cavuto, MS, RD, the dietitian to the Philadelphia Phillies and Flyers, likes having washed and prepared cucumbers, peppers, sugar snap peas, and carrots in the front of the fridge so they aren't overlooked. Bananas, apples, pears and oranges fare well as sweet snacks and should be kept on the counter where you can see them. To discover more healthy foods that will help you lose weight, check out these best foods for muscle definition.

Keep Electronics Out of the Bedroom

Is scrolling through an Instagram black hole costing you zzz's? It might be the reason you can't shake those love handles. In a recent study, researchers analyzed more than 500 participants' weekday sleep diaries and found that losing a mere 30 minutes of shut-eye increased their risk of obesity by 17%!

Read Ingredient Lists

Reading the nutrition label of packaged foods is important, but you also want to carefully review the ingredients list. While the nutrition label will tell you how many calories and grams of fat and sugar are in the food, the ingredients list will tell you what's exactly in it. Ask yourself: Does it have processed oils? What is the source of the sugar content? Are there food additives?

Throw Out Jelly and Jam

Your breakfast toast won't miss these sugar-laden spreads when you start to shed pounds and notice a flatter belly. One tablespoon of jam easily carries just under 10 grams of sugar. And let's be honest, who just has one? Top peanut butter sandwiches with fresh pieces of fruit, like banana and strawberry slices to infuse it with some natural sweetness. This tactic will help ward off blood-sugar fluctuations that can cause insulin spikes and put hunger into overdrive.

Skip Sugary Cereal

There's no sugar-coating it: Sugar wreaks havoc on the body. Consuming too much of the white stuff can lead to obesity, which often causes other health problems, like diabetes and heart disease. Many unhealthy breakfast cereals pack more sugar into one bowl than you'll find in a Boston Kreme donut! To make matters worse, many popular varieties like Frosted Flakes and Fruity Pebbles are laced with Butylated Hydroxytoluene (BHT) or BHA (Butylated Hydroxyanisole). These ingredients are banned in the U.K., Australia, New Zealand, Japan and much of Europe because they are thought to be carcinogenic.

Say Goodbye to Soda

"Soda, both diet and regular, have absolutely no nutritional benefits and may even have serious health implications," says Gina Consalvo, MA, RD, LDN, a Pennsylvania-based registered dietitian. "Not only are they loaded with empty calories, harmful preservatives, sugar or artificial sweeteners, they also have dangerous artificial coloring derived from coal sources," explains Consalvo. But that's not even the worst part. "To prevent mold growth in the cans and bottles, makers add the preservative potassium benzoate (a known carcinogen linked to thyroid damage, leukemia and other cancers) into the cans." Consalvo suggests eliminating soda and drinking water, seltzer or detox tea instead.

Forgo White Carbs

Many of us grew up eating white bread and bagels, so we understand why they may hold a special place in your heart. But these starchy grains (and things like white rice and pretzels) are anything but healthy. Made with enriched flour instead of healthy whole grains, they're void of the belly-filling fiber that boosts satiety and keeps blood sugar stable. What's worse, refined white-flour foods like these are linked to heart disease and type 2 diabetes. Plus, they lead to weight gain and make it more difficult to lose weight, too. For more ways to get the slim body you crave, check out these ways to lose 10 pounds—fast.

Kick Processed Snacks to the Curb

Processed snacks filled with saturated fats, sugar, refined grains and harmful chemicals. It's no wonder they're some of the biggest weight-loss saboteurs! To discover the worst snacks for weight loss in the supermarket, check out these unhealthiest foods on the planet.

Ditch the Margarine

You know that light yellow color that makes margarine look almost indistinguishable from butter when laid side by side? Well, it's far from natural. In fact, without all the additives, margarine is actually an appetite-crushing shade of grey—yuck! As if that weren't bad enough, many brands add propylene glycol, a synthetic compound, to their recipe to add grease without adding calories. Research has shown that the spread may expand your waistline, increase dangerous cholesterol levels and up your heart disease risk.

Limit Chewing Gum

Chewing gum when you're hungry fills your tummy with extra air, causing bloat. Many gums also contain sugar alcohols and artificial sweeteners, like sorbitol and xylitol, which can lead to bloating. Skip the gum altogether or opt for an organic variety like Glee gum or Simply gum instead. They're still low-cal, but they don't use sweeteners that'll make you puff up.

Stock Up Your Kitchen

After you've gotten rid of the weight loss saboteurs, it's time to restock your shelves with Zero Belly-approved eats. All of the foods below will reduce bloat, heal your gut and turbocharge your metabolism. These three mechanisms work in tandem to turn off your fat genes—resetting your body to "slender."

Stock Up on Smoothie Ingredients

Zero Belly Smoothies are supercharged with belly-flattening nutrients. The key: Each drink is packed with protein, healthy fats, and fiber. Here's the Mango Muscle-Up: Mix 1 scoop vegetarian protein powder, 2/3 cup frozen mango chunks, 1/2 tablespoon almond butter, and 1/2 cup unsweetened almond, coconut, or hemp milk. You'll get 29 grams of protein for just 224 calories!

Shop for Eggs

Eggs are the number one source of choline, a fat-burning nutrient. They fire up your metabolism and help turn off the genes for belly fat storage. In a study of 21 men in the journal Nutrition Research, half of the men were fed a breakfast of bagels while the other half ate eggs. The egg group had a lower response to ghrelin and were less hungry three hours later. They also consumed fewer calories for the next 24 hours! And speaking of belly fat, lose more of it with the help of these ways to lose belly fat.

Favor Red Fruits

More and more research has begun to show that some fruits are actually better at fighting belly fat than others. And the better fruits all have one thing in common: They're red, or at least reddish. Grapefruit, tart cherries, pink lady apples, raspberries, strawberries, watermelon, and peaches all fit the bill and can help flatten your belly.

Pack in Prebiotics

Healthy fiber is what we call "prebiotic," meaning it feeds the healthy bacteria and helps them fight inflammation and fat gain. Fiber-rich sources of carbs are BPA-free canned black and garbanzo beans, peas, peanuts, peanut butter, old-fashioned oats, quinoa and brown rice. Looking for tasty ways to enjoy your oatmeal? Check out these overnight oats recipes!

Opt for Plant Protein

Plant-based protein powders are a low-sugar, high-fiber alternative to popular dairy-based supplements, which can lead to bloating. Hemp, rice and pea proteins are all good options; however, you'll want to ensure you're getting complete proteins with a full amino acid profile, so aim to find a protein powder blend that combines all three. We like Vega One All-in-One Nutritional Shake and Sunwarrior Warrior Blend. Whip up any of these best protein shake recipes to reap the benefits. Even if they call for whey protein, you can sub-in your plant-based favorite.

Go for Lean Meat and Fish

Protein is kryptonite to belly fat. When you eat protein, your body has to expend a lot of calories in digestion—about 25 calories for every 100 calories you eat (compared with only 10 to 15 calories for fats and carbs). With that said, stock your kitchen with boneless skinless chicken breast, lean ground turkey, lean beef, lamb, wild salmon, shrimp, scallops, cod, tuna, and halibut.

Glorify Your Greens

Leafy greens give you folate, which blocks the genes that trigger fat-cell formation. Romaine lettuce, spinach, and collard greens are some of the most potent sources of the flat-belly nutrient. For more ways to supercharge your weight loss, check out these best ways to boost your metabolism.

Indulge in Dark Chocolate

It's every chocoholic's dream: Research now shows that eating moderate amounts of dark chocolate can reduce overall body fat and shrink the waist. A study among women with normal weight obesity (skinny fat syndrome) who enjoyed two servings of dark chocolate daily showed a significant reduction in waist size than when on a cocoa-free meal plan.

Researchers say it has to do with the flavonoids, the heart-healthy compounds in chocolate, that have important antioxidant and anti-inflammatory properties. Just be sure you're reaching for a bar with at least 70% cacao, and stay away from the "alkalized" stuff, which has a significantly reduced flavonoid content. We like nib mor Organic Dark Chocolate with Cacao Nibs.

Sip Some Tea

You know all that soda we told you to throw out? Use all that money saved to re-stock your kitchen with tea. Tea is the closest thing we currently have to magic weight-loss elixir. Rich in health-promoting compounds called catechins, tea can help fry stubborn belly fat and even fight off disease.

Adopt Healthy Eating Rituals

There are no wrong ways to eat a Reese's. Feasting rituals, research suggests, are a form of "mindful eating," which has the power to make food more pleasurable, and may help prevent overeating. Pleasure, according to research in Trends in Endocrinology and Metabolism, catalyzes the relaxation response, promoting parasympathetic and digestive activities. In other words, you'll metabolize dessert faster if you really, really enjoy eating it. In one study, participants who were assigned to eat a chocolate bar in accordance with a particular breaking and unwrapping ritual found the candy much more enjoyable—and even more flavorful—than a group who ate the bar informally.

Change Your Perception of "Full"

Hara hachi bu is a Japanese practice to "Eat until 80% full." If you follow Hara hachi bu, you could save nearly 300 calories per day. It can take up to 30 minutes for the body to register satiety signals, according to research, so consider using chopsticks to slow your pace and feel your fullness. According to a study in the American Journal of Preventive Medicine, healthy-weight customers were nearly three times more likely to use chopsticks than obese customers.

Jot Down Your Thoughts

A study revealed that when women who were unhappy with their weight completed a one-time, 15-minute writing exercise about an important personal issue, they went on to lose at least three pounds over a three-month period. On the other hand, their counterparts who wrote about an unimportant topic gained three pounds, according to Cheryl Forberg, RD, author of A Small Guide to Losing.

"Researchers believe that reflecting on values can serve as a buffer to the stress and uncertainty that leads to emotional eating and help in maintaining self-control in difficult situations," she explains. To reap the benefits at home, Forberg suggests pulling out a journal, setting the timer and free-flowing about what's important to you. "Write as though no one else will read it. Come clean with what's bugging you. It may surprise and enlighten you," adds Forberg. For more weight loss hacks, check out these quick ways to lose weight.

Treat Yourself

Beating yourself up over food is a knowledge-behavior gap many unsuccessful dieters fall into. Calling yourself "greedy" or a "fat pig" or "weak-willed" only makes you feel bad about yourself, which often leads to eating more in an attempt to give yourself a boost. It's important to try to stop the negative self-talk, says Freida B. Herron, M.S.S.W., L.C.S.W. "I often suggest imagining that your desire to overeat is a lovable 5-year-old child," she says. "You don't want to berate or shame your appetite—that only leads to more dysfunctional eating." Instead, treat yourself with respect, understanding, and affection, as you would that child.

And when that seems near impossible to do, try chanting a mantra that has a personal meaning to you, suggests Jen Comas Keck, a personal trainer and owner of Beauty Lies In Strength. If you've been working on your fitness, for example, something like "I feel stronger and healthier every day that passes" may be effective.

Identify the Root of Your Emotional Eating

If you're the type of person that drowns your sorrows in a pint of ice cream, you might be what experts refer to as an "emotional eater"—and it's likely the primary reason you have trouble staying trim. To lose weight, you need to first learn the difference between emotional hunger, which comes on suddenly, and physical hunger, which comes on gradually and is often accompanied by physical cues like a growling stomach, explains Forberg. The best way to overcome the urge to eat? Realize that although a bad feeling will eventually go away, the calories you consumed while you were feeling down, won't. And the next time you're feeling emotional, don't try to mask your emotions or distract yourself. Experts say that truly experiencing your emotions will teach you that it's possible to tolerate them head-on. Once you've done this exercise, it's time to find a new, healthy coping strategy. Hitting the gym or calling a friend to vent are both solid options.

Celebrate Your Non-Scale Victories

Losing weight can be just as hard emotionally and physically. Remembering why you started your weight-loss journey can help lift your spirits when you're down and motivate you to stick with it when you want to throw in the towel. "Take a moment each morning to remember what you're working for—whether it be improved energy so you can play with your children or a longer happier life," says Dyan Tsiumis, who dropped more than 70 pounds before becoming a personal trainer. "When you focus on all the good that will come from all of your hard work, it's easier to stay on track," she adds.

Tsiumis suggests setting an alarm on your cell phone as a "motivation reminder." "I have an alarm that goes off three times per day to remind me what I'm working for—and I lost my weight over ten years ago! It keeps my mind focused on being my best," explains Tsiumis.

Lift Before Cardio

By running, biking or rowing after you've hit the weights, you'll have a greater effect on your fat and calorie burn than had you done it beforehand. And don't do any of these things you're doing to slow your metabolism!

Sprint it Out

Sprinting is better for weight loss than running at a steady pace, says Dan Roberts, one of the UK's top trainers. "Sprinting builds muscle which helps burn fat quickly. Also, the action of driving the legs initiates the abs and core" explains Roberts. "The faster you go and the shorter your recovery, the more your abs will develop." Instead of your typical 30-minute trot, do 20 sets of 30-second sprints with a 30-second recovery between each. Here's how to do it:

Step 1: Keeping your feet on either side of the belt, set your treadmill to a 10% incline. Then, set the machine to a challenging speed. This is typically at least two miles per hour faster than your distance running speed. So, for example, if you typically jog at 6.5 mph, you're full-on sprint speed will be at least 8.5 mph.

Step 2: Hit the ground running for a solid 30-seconds. Then, slow the belt to a comfortable stroll and step your feet off to either side once you feel comfortable. Recover for a total of 30 seconds before repeating this pattern 19 more times. These circuits should take you exactly 20 minutes to complete.

Hop On a Rower

Rowing burns many calories and works the most muscles, including your back muscles. To bump it up a notch, take your workout outdoors. In a Brazilian study, outdoor rowers burned 26% more calories during a race than those on an indoor rowing ergometers.

Focus on Pushups

Although push-ups will emphasize the upper-body, including the shoulders and arms, they're actually full-body exercises. "When done properly, they actually work your entire body and are one of the very best ways to target your external obliques," says Annie Mulgrew, director of programming at City Row.

Sculpt Love Handles with Side Planks

If you want to get rid of those stubborn love handles, side planks are the perfect exercise for toning your obliques. By challenging your balance, side planks force you to recruit other muscles to stabilize your body.
