15 Foods to Avoid if You Want to Have a Flat Stomach

Do you ever feel like your diet is holding you back from optimal health? You're not alone. Dr. Nick Zyrowski, D.C, B.S., a doctor and clinician, is on a mission to help people transform their health naturally. With his expertise in nutrition and wellness, Dr. Zyrowski shares insights on the foods we should avoid for better health. Joining him are other experts like Dr. Mark Hyman, a pioneering functional medicine physician, and Kaytee Hadley, MS, RDN, IFMCP, CPT, a functional medicine dietitian. Together, these health gurus reveal the top foods that might be sabotaging your well-being. Read on to discover which foods you should eliminate from your diet today — your body will thank you for it!

Ditch the Bleached White Flour and Refined Grains

Dr. Zyrowski warns against consuming bleached white flour and refined grains. "This is a grain that's gone through a process where the nutrient-rich wheat kernel has been removed, and so any vitamins and minerals it may have had to begin with are now gone," he explains in his post. These processed grains are often treated with chemicals like benzoyl peroxide and chlorine. Found in many staple foods like bread, pasta, and crackers, these refined grains are far from being real, nutritious food.

Say Goodbye to Low-Fat Foods

Contrary to popular belief, low-fat foods are not the answer to a healthy diet. Dr. Zyrowski debunks this myth, stating, "The idea that we should eat low-fat foods is probably one of the biggest lies ever pushed on people." He reminds us that our brain is 80% fat, and our body's cells have fatty membranes. Instead of low-fat options, he recommends full-fat alternatives like raw almond butter, plain full-fat yogurt, and whole milk from grass-fed cows.

Avoid Processed Deli Meats

Deli meats often contain hidden ingredients that can be harmful to your health. "Deli meats can be loaded with a lot more ingredients than you ever bargained for," cautions Dr. Zyrowski. These processed meats often contain added sodium, nitrates, artificial flavorings, and even corn syrup. He suggests opting for whole, unprocessed meats instead.

Cut Out Sugary Drinks

Sugary beverages are a major culprit in poor health. Dr. Zyrowski warns, "There's not a better way to create a problem like insulin resistance in your body than drinking these types of beverages." This includes not just sodas but also fruit juices, sweetened teas, and energy drinks. He recommends choosing water, sparkling water, or stevia-sweetened beverages instead.

Dr. Zyrowski underlines the dangers of sugar, noting that many people may have insulin resistance without realizing it. He advises avoiding foods like cereals, snack bars, candy, sweetened yogurt, and ice cream. "Sugar comes in over 250 names on the food label," he warns, suggesting we look for ingredients ending in "-ose" to identify hidden sugars.

Steer Clear of Fried Foods

Fried foods, including chips, french fries, and fried meats, are best avoided. Dr. Zyrowski explains that these foods create "a lot of inflammatory advanced glycation end products" and oxidative stress in the body, which can lead to various health issues. Kaytee Hadley, MS, RDN, IFMCP, CPT, adds, "Fried chicken, for example, may have high protein content, but the fried food can increase levels of inflammation that may actually lead to weight gain."

Beware of Bad Fats

While healthy fats are essential, many common fats are harmful. Dr. Zyrowski advises against vegetable oils, canola oil, soybean oil, and margarine. "These fats are all inflammatory, and they lead to inflammatory conditions," he states. Instead, he recommends healthy fats like coconut oil, avocados, butter, nuts, seeds, and olive oil.

Eliminate Fast Foods

Fast foods, whether from restaurants or pre-packaged meals, are loaded with unhealthy ingredients. Dr. Zyrowski notes that these foods often contain "the sugar, the preservatives, the bad fats" mentioned earlier. Despite their convenience, he strongly advises against consuming fast foods.

Ban Artificial Flavorings, Sugars, and Dyes

At the top of Dr. Zyrowski's list are artificial additives. "Artificial means not found in nature, made in a lab, a.k.a. fake food," he explains. These additives are often used to keep costs low and profits high, but they're linked to serious health issues, including cancer.

Avoid Foods with Unpronounceable Ingredients

Dr. Mark Hyman, a leading physician, advises, "First of all, if you read something on a label and you don't know what it is and you can't pronounce it, don't eat it." He gives an example: "Butylated hydroxytoluene, or BHT, is a known carcinogen that's banned in most countries except the United States."

Say No to High Fructose Corn Syrup

Dr. Hyman considers high fructose corn syrup a "hard rule" to avoid. He explains, "It's not a whole food and is a highly processed industrial food product." He warns that it can cause insulin resistance and inflammation and elevate uric acid levels.

Limit Artificial Sweeteners

Dr. Hyman also advises against artificial sweeteners. "It has a huge effect on your microbiome. It causes fermentation, bloating, distension," he explains. Dr. Jacqueline Wolfadds, "Avoid sugar alcohols (which end in -ol) such as sorbitol, mannitol, xylitol and erythritol. They cause gas and often bloating because we cannot break them down."

Be Cautious with Carbonated Beverages

Carbonated drinks can contribute to bloating. Beth Czerwony, RD, explains, "Think about what happens if you shake a can of soda. That's what is happening inside of you after you drink it. The bubbles have no place to go — and it will make you feel bloated."

Watch Out for High-Sodium Foods

The Cleveland Clinic warns, "Eating meals that are high in sodium, high in fat or heavy with refined carbohydrates (such as bread, buns or breading) can all leave you feeling bloated."

What foods support loss of belly fat, or help keep off the weight? Come along with me, and let’s take a look! My name is Annette Snyder, and I’ve been a registered dietitian (RD) for nearly 20 years, now working with Top Nutrition Coaching. I’ve had extensive experience in the practice areas of weight management, diabetes care, and digestive disorders. I currently maintain additional board certification (CSOWM) in weight management through the Commission on Dietetic Registration, the credentialing body for the Academy of Nutrition and Dietetics. I’m passionate about the new things nutrition science is teaching us. My goal is sharing that knowledge in a way that inspires others to get curious about their health. The foods that support intended weight loss share some qualities in common (1-3). They tend to be higher in fiber, contain a decent amount of protein, and fewer inflammatory fats (saturated). Read on for my list of 10 ways to eat for abs.

1. Fruits and Veggies

Shutterstock

This is a no-brainer. A number of scientific studies (4) have suggested links to eating more produce, especially veggies, with lower risk of gaining weight and lower waist circumference. Plus, you know, you get vitamins and minerals. Bonus!

2. Whole Grains

Shutterstock

These include oats, buckwheat, quinoa, barley and others. While they’re full of gut-friendly fiber, vitamins, minerals, and antioxidants, they also help manage blood sugar. Keeping your blood sugar in check means you deal with fewer mid-afternoon cravings (5) for all things carb. Whole grains have also been associated with appetite control and can affect how the body uses energy (calories) from food (6).

3. Heart-Healthy Fats

Heart-healthy fats from fish (like tuna, mackerel, salmon), in addition to calming inflammation in the body, have a role in weight control by promoting lower belly fat and unhealthy triglyceride levels (blood fats) (7). Fish is also a rich protein source, which is important in maintaining muscle mass. Protein has been linked to reduced appetite (8) along with fiber.

4. Nuts and Seeds

Shutterstock

Not to be outdone in the nutrient department, nuts and seeds provide boosts of fiber, protein, and healthy fats. Various smaller studies have observed reductions in belly fat and/or waist circumference when consuming almonds (9) or chia (10), for example. There are tons of options—pumpkin seeds, sunflower seeds, walnuts, pistachios, just to name a few—and they’re great for snacking!

5. Green Tea

Green tea has also entered the conversation. It contains the compound EGCG, which has been observed to bump up your calorie burn (11). Various studies have also found loss of belly fat and waist circumference with regular intake of green tea (12). Aside from EGCG, green tea is loaded with antioxidants.

6. Keep Your Gut Happy With Probiotics

What about the bacteria in our digestive tract? They play a role, too! More studies in recent years (13) have identified the role of our microbiome in appetite as well as metabolism. At present, we continue to investigate what those microbes are doing that has those effects. Various strains such as Lactobacillus and Bifidobacterium have been looked at (14) more closely for a possible link in weight loss—stay tuned. In the meantime, keep your gut happy with some probiotics from food: kefir, yogurt, kimchi, sauerkraut, and aged cheeses are some great sources.

7. Hydrate Right

How about your hydration? Do you drink enough fluid (especially water) on a daily basis? Your body uses water in its day-to-day function to perform tasks like burning calories. It’s kind of like the oil that makes the machine work better. A study on hydration and health in older adults (15) found a strong link between low fluid intake/dehydration and increased occurrences of weight gain, high waist circumference, insulin resistance, diabetes, low HDL (good) cholesterol, high blood pressure, and metabolic syndrome. Drink up!

8. Think About How You Eat, Not Just What You Eat

Shutterstock

Aside from what we eat and drink (or don’t), how we eat can have a big impact. Are you known for finishing your meal well before everyone else at the table? (Do you taste your food?) Take a pause. Slowing down actually lets your body do its thing and send you the message that you have taken in enough fuel (calories). You cruise right on by that point and don’t hear the message when you rush the process—resulting in eating more calories than you actually need.

9. Avoid Added Sugars

Shutterstock

Of course, I’m going there: we tend to eat too much added sugar. Added sugar (vs naturally-occurring sugar in things like fruit or milk) has number of drawbacks. Added sugars don’t add nutrition. Our bodies aren’t set up to process the large quantities we are capable of ingesting, and figuring out what to do with that extra fuel is where we see fat storage start. A large review of the available studies aimed to determine what happens with excess sugar intake (16), and it ain’t pretty. Significant links between sugar intake and higher weight, along with a host of other conditions such as heart disease and depression, have been suggested. Sugar-sweetened drinks are the biggest culprit: soda, fruit drinks, sweet tea, and coffee drinks. (As a coffee lover myself, that last one hits hard.)

10. Avoid Alcohol

Shutterstock

Alcohol has been linked to belly fat for quite some time now. Various studies have found links between drinking and increased waist circumference (17), especially if consuming in larger quantities (18). Calories from alcohol are not stored like carbohydrates (19) (glycogen); rather the body stores them as fat. Essentially, alcohol offers calories, just like added sugars, and no nutrition benefit.

11. Final Word From the Expert

Shutterstock

While a number of foods can provide benefits that support weight loss, it’s important to remember that you don’t eat in a vacuum. What do I mean? Eating more almonds while living on fast food isn’t going to do the job. Get your house in order with all of your food and drink choices to see real results.
