The 30 Best Ways to Get a Flat Stomach

 Losing the fat around your midsection can be a battle.

In addition to being a risk factor for several diseases, excess abdominal fat may make you feel bloated and discouraged.

Luckily, several strategies have been shown to be especially effective at reducing your waist size.

If you dream about having a flat stomach, this article may be just what you need.

Here are 30 science-backed methods to help you reach your goal of a flat stomach.

1. Cut Calories, but Not Too Much

It is a well-known fact that you need to cut calories to produce weight loss.

One popular approach is to reduce your daily intake by 500–1,000 calories to expect to lose approximately 1–2 pounds (0.5–1 kg) per week (1Trusted Source).

That being said, restricting your calorie intake too much can be counterproductive.

Eating too few calories can cause a major decrease in your metabolic rate, or the number of calories you burn on a daily basis (2Trusted Source3Trusted Source4Trusted Source5Trusted Source).

In one study, a group of people who ate 1,100 calories per day slowed their metabolic rate more than twice as much as those who consumed about 1,500 calories per day for four consecutive days (5Trusted Source).

What’s more, this decrease in metabolic rate may persist even after you start behaving like you normally do. That means you may have a lower metabolic rate than you had before you severely restricted your calorie intake (4Trusted Source6Trusted Source).

Therefore, it is important that you don’t restrict your calorie intake too much or for too long.


Eating too few calories may slow your metabolic rate, even in the long term. Therefore, it is important not to restrict calories too much or for too long.

2. Eat More Fiber, Especially Soluble Fiber

Soluble fibers absorb large quantities of water and slow down the passing of food through the digestive tract.

This has been shown to delay stomach emptying, causing the stomach to expand and make you feel full (78Trusted Source).

Furthermore, soluble fiber may decrease the number of calories your body is able to absorb from food (9Trusted Source).

By eating soluble fiber, you are also less likely to accumulate fat around your organs, which reduces your waist circumference and the risk of several diseases (10Trusted Source).

One observational study showed that each 10-gram increase in daily soluble fiber intake decreased fat gain around the midsection by 3.7% over five years (11Trusted Source).

Good sources of soluble fibers include oats, flaxseeds, avocados, legumes, Brussels sprouts and blackberries.


Eating soluble fiber has been linked to a reduced risk of developing fat around your midsection.

3. Take Probiotics

Probiotics are live bacteria that are suggested to play a big role in weight loss and weight maintenance (12Trusted Source13Trusted Source).

Overweight and obese people have been shown to have a different composition of gut bacteria than normal-weight people, which may influence weight gain and fat distribution (14Trusted Source15Trusted Source16Trusted Source).

A regular intake of probiotics may shift the balance towards beneficial gut flora, reducing the risk of weight gain and fat accumulation in your abdominal cavity.

Some strains of probiotics have been shown to be particularly effective at reducing belly fat. These include (17Trusted Source18Trusted Source1920Trusted Source21Trusted Source):

  • Lactobacillus fermentum
  • Lactobacillus amylovorus
  • Lactobacillus gasseri

Probiotic foods include some types of yogurt, kefir, tempeh, kimchi and pickles.

There are also a wide variety of probiotic supplements available. However, these supplements usually contain several strains of bacteria, so make sure to pick one that contains at least one of the strains mentioned above.


Probiotics may help build up beneficial gut flora. Some Lactobacillus strains have been shown to be particularly effective at reducing waist size.

4. Do Some Cardio

Doing cardio, or aerobic exercise, is an excellent way to burn calories and improve overall health.

Additionally, studies have shown that it is very effective at strengthening your midsection and reducing your waistline (22Trusted Source23Trusted Source24Trusted Source25Trusted Source).

Studies usually recommend doing 150–300 minutes of moderate-to-high-intensity aerobic exercise weekly, which translates to roughly 20–40 minutes per day (26Trusted Source27Trusted Source).

Examples of cardio include running, brisk walking, biking and rowing.


Doing moderate-to-high-intensity cardio for 20–40 minutes per day has been shown to be effective at reducing belly fat.

5. Drink Protein Shakes

Protein shakes are an easy way to add extra protein to your diet.

Getting enough protein in your diet can boost your metabolism, reduce your appetite and assist with fat loss, especially from your midsection (28Trusted Source29Trusted Source30Trusted Source31Trusted Source).

Furthermore, studies have suggested that adding protein shakes to your weight loss diet may be especially effective at reducing your waist circumference (32Trusted Source33Trusted Source34Trusted Source).


Protein shakes are an easy way to add extra protein to your diet. Including them as part of a weight loss diet has been shown to be effective at reducing your waist size.

6. Eat Foods Rich in Monounsaturated Fatty Acids

Monounsaturated fatty acids are liquid at room temperature and usually categorized among the “good fats.”

Studies show that diets high in monounsaturated fatty acids may prevent the accumulation of tummy fat, the most dangerous type of fat (35Trusted Source36Trusted Source).

The Mediterranean diet is an example of a diet that is high in monounsaturated fatty acids, and it has been linked to many health benefits, including a reduced risk of central obesity (37Trusted Source38Trusted Source).

Foods high in monounsaturated fatty acids include olive oil, avocados, nuts and seeds.


Diets high in monounsaturated fatty acids may reduce the risk of central obesity.

7. Limit Your Intake of Carbs, Especially Refined Carbs

Limiting your carb intake has been shown to have powerful health benefits, especially for weight loss (39Trusted Source40Trusted Source).

More specifically, studies show that low-carb diets target the fat that lodges around your organs and makes your waistline expand (41Trusted Source42Trusted Source43Trusted Source44Trusted Source).

Some studies also suggest that you can significantly improve your metabolic health and reduce your waistline by simply replacing refined carbs with unprocessed, whole food carbs (45Trusted Source46Trusted Source).

Observational studies have shown that people with the highest intakes of whole grains are 17% less likely to have excess abdominal fat than those who consume diets high in refined carbs (47Trusted Source).


Limiting your total carb intake, as well as simply replacing your refined carb intake with whole food carbs, may reduce your waist circumference and improve your health.

8. Do Resistance Training

Losing muscle mass is a common side effect of dieting.

This can be detrimental to your metabolic rate, as losing muscle decreases the number of calories you burn on a daily basis (48Trusted Source).

Doing resistance exercises regularly may prevent this loss of muscle mass and, in turn, help you maintain or improve your metabolic rate (49Trusted Source50Trusted Source).

Moreover, resistance training may be especially effective at tightening your midsection and reducing your waist size (51Trusted Source52Trusted Source).

In fact, combining resistance training with aerobic exercise seems to be the most effective for slimming your waistline (53Trusted Source).


Resistance training may prevent the loss of muscle mass often seen with dieting, which may help maintain your metabolic rate and reduce your waist circumference.

9. Do Exercises Standing Instead of Sitting

Performing exercises while standing up may benefit your health more than performing the same exercises while sitting or using weight machines.

By standing, you activate more muscles to maintain balance and hold up your weight. Therefore, you’ll spend more energy working out (54Trusted Source).

A study comparing the effects of standing and sitting exercises showed that some standing exercises increased muscle activation by 7–25%, compared to sitting (55Trusted Source).

Another study suggested that standing may improve your breathing, compared to sitting (56Trusted Source).

Although this may seem like a minor alteration, it may strengthen your midsection and is worth a try.


Doing exercises while standing instead of sitting may burn more calories, activate your muscles more and improve oxygenation and breathing ability.

10. Add Apple Cider Vinegar to Your Diet

Apple cider vinegar is linked to several impressive health benefits, most of which are mainly attributed to its content of acetic acid.

Several animal studies have suggested that acetic acid may reduce body fat accumulation (57Trusted Source58Trusted Source59Trusted Source).

Although human studies are somewhat lacking in this area, one study in obese men showed that taking one tablespoon of apple cider vinegar each day for 12 weeks reduced their waistlines by 0.5 inches (1.4 cm), on average (60Trusted Source).

Apple cider vinegar is mainly made up of acetic acid, a compound that may reduce body fat accumulation.

11. Walk at Least 30 Minutes Each Day

A combination of diet and exercise is probably the most effective way to achieve weight loss and improve your overall health.

Interestingly, studies have shown that you don’t need to exercise vigorously to reap health benefits.

Regular, brisk walks have been shown to effectively reduce total body fat and the fat located around your midsection (61Trusted Source62Trusted Source).

In fact, walking briskly for 30–40 minutes (about 7,500 steps) per day has been linked to a significant reduction of dangerous tummy fat and a slimmer waistline (63Trusted Source).


Walking for 30 minutes daily may slim your waistline and prevent the accumulation of dangerous tummy fat.

12. Avoid Liquid Calories

Sugary soda, fruit juices and energy drinks are generally loaded with sugar and liquid calories.

It is also very easy to drink large quantities at a time, resulting in an abundance of empty calories.

The thing with liquid calories is that your brain doesn’t register them like it registers solid calories. Therefore, you’ll end up consuming these calories on top of everything else that you eat or drink (64Trusted Source65Trusted Source).

One study showed that each daily serving of a sugar-sweetened beverage increased the risk of obesity by a whopping 60% in children (66Trusted Source).

These drinks are also generally loaded with fructose, which has been linked directly to belly fat gain (67Trusted Source68Trusted Source69Trusted Source).


Your brain doesn’t register liquid calories like it registers solid calories. Therefore, they’re added on top of everything else you eat and contribute to weight gain.

13. Eat Whole, Single-Ingredient Foods

The single best dietary advice you can give someone is to base their diet around eating more whole, single-ingredient foods.

Whole foods are loaded with nutrients, fiber, water, vitamins and minerals.

This makes it very difficult to overconsume these foods, some of which even have their own benefits for preventing weight gain (70Trusted Source71Trusted Source).

Try to eat plenty of whole grains, nuts, legumes, fruits, vegetables, dairy, fish and unprocessed meat.


Whole, single-ingredient foods are loaded with nutrients, and it’s hard to eat too much of them.

14. Drink Water

There are at least three ways in which water may help you achieve a flat stomach.

First, it may help with weight loss by temporarily increasing your metabolic rate.

In fact, drinking water may increase your total energy expenditure by up to 100 calories per day (72Trusted Source73Trusted Source).

Second, drinking water before meals can make you feel fuller, so you’ll ultimately eat fewer calories (74Trusted Source75Trusted Source76Trusted Source).

Third, it may help relieve constipation and reduce belly bloating (77Trusted Source78Trusted Source79Trusted Source).

Try drinking a large glass of water before each meal. It may help you achieve your goal.


Drinking water may increase your metabolic rate, make you feel fuller and help relieve constipation, all of which may help you achieve your goal of a flatter stomach.

15. Practice Mindful Eating

Mindful eating is a technique that helps you recognize and cope with your emotions and physical sensations regarding food and hunger (80Trusted Source81Trusted Source).

It involves slowing down, eating without distraction, focusing on your physical hunger cues and eating only until you feel full (82Trusted Source).

Most studies agree that mindful eating helps you lose weight by changing your eating behavior and reducing stress-related behavior, such as stress eating and binge eating (82Trusted Source83Trusted Source84Trusted Source).

Also, it is more likely to help you keep the weight off in the long term, as it focuses on changing your behavior.


By eating mindfully, you can focus on your physical hunger and eating only until you’re satisfied. That reduces the risk of stress eating and binging.

16. Avoid Swallowing Air and Gases

The biggest source of gas in the diet is carbonated beverages such as soda.

The bubbles in it contain carbon dioxide, which is released from the liquid in your stomach. This may cause stomach distention or bloating.

This can also happen when you chew gum, drink through a straw or talk while eating.

Eating in silence, drinking from a glass and swapping carbonated drinks out for water may help you achieve a flatter stomach.


Carbonated drinks and gum may both cause stomach distention and bloating in some people.

17. Do High-Intensity Training

One popular way to do high-intensity training is to perform intervals of very intense activity, such as sprinting, rowing or jumping, with short breaks in between.

This way of exercising makes your body burn more fat and increases your metabolic rate, even long after you’ve finished your workout (85Trusted Source86Trusted Source87Trusted Source88Trusted Source).

High-intensity training has been shown to have superior effects on fat burning, compared to other types of exercises, and is especially effective for slimming the waistline (89Trusted Source90Trusted Source91Trusted Source).

What’s more, this type of exercise takes up way less of your time than other types of exercise, as it usually can be done in 10–20 minutes.


High-intensity training increases fat burning and metabolic rate, even long after your workout is over. It is especially effective for slimming the waistline.

18. Reduce Your Stress Levels

Stress and anxiety are very common, and most people experience them at some point in their lives.

Stress is linked to the development of many diseases, and it is also a common reason why people tend to eat or binge eat, often without being hungry in the first place (92Trusted Source93Trusted Source).

Also, stress triggers the body to produce cortisol, a stress hormone. It has been known to increase appetite and lead specifically to belly fat storage (94Trusted Source95Trusted Source96Trusted Source).

This may be especially harmful in women who already have a large waist, as they tend to produce more cortisol in response to stress, which further adds to belly fat gain (97Trusted Source).

Try to add some stress-relieving activities to your daily routine, such as yoga or meditation.


Stress triggers the production of cortisol, which increases appetite and drives belly fat storage.

19. Eat More Protein

Protein is the most important nutrient when it comes to weight loss.

Your body burns more calories digesting protein than fat or carbs. Therefore, a high-protein diet may account for an extra 80–100 burned calories per day (98Trusted Source99Trusted Source).

High-protein diets also reduce your appetite, make you feel full and help you retain your muscle mass during weight loss (30Trusted Source100Trusted Source101Trusted Source102).

Furthermore, studies have observed that people who eat more protein have slimmer waistlines than those with lower protein intakes (32Trusted Source34Trusted Source103Trusted Source).

How much protein you need depends on many factors, such as your age, gender and activity level.

Generally, you should aim to get 20–30% of your calories from protein on a daily basis. This can easily be achieved by incorporating a protein source in every meal.


High-protein diets may increase your metabolic rate, reduce your appetite and help you retain muscle mass during weight loss. They are also linked to lower abdominal obesity rates.

20. Track Your Food Intake

When you’re trying to lose weight, it can be helpful to track your food intake.

There are several ways to do this, but the most popular and effective ones are counting calories, keeping a food diary and taking pictures of your food (104Trusted Source105Trusted Source106107Trusted Source).

You don’t have to do this all the time, but it may be good to track your intake for a few days in a row every few weeks. This will make you more aware of your calorie intake and allow you to adjust your weight loss diet if needed.

Studies generally agree that people who track their food intake are more likely to reach their weight loss goals (108Trusted Source).

Here are five free apps or websites that allow you to easily track your nutrient and calorie intake.


Tracking your food intake once in a while may help you lose weight by making you more aware of your calorie intake.

21. Eat Eggs

Eggs are healthy, high in protein and have a few unique weight loss properties.

A large egg is very nutritious and contains only about 77 calories (109).

Studies have shown that eating eggs for breakfast as part of a calorie-restricted diet may cause up to 65% greater weight loss over eight weeks, compared to other types of breakfast foods (110Trusted Source111Trusted Source).

An egg breakfast has also been shown to significantly reduce calorie intake for the next 24 hours, automatically and without effort (100Trusted Source112Trusted Source).

Moreover, eggs have been shown to be more effective at reducing waist size than other foods with the same calorie content (111Trusted Source113Trusted Source).


Eggs have well-established weight loss properties and may be more effective at reducing waist circumference than other foods when matched for calories.

22. Get Enough Sleep

Getting a sufficient amount of good sleep is very important for weight loss.

Studies have repeatedly shown sleeping less than five hours a night for adults and less than 10 hours for children is linked to an increased risk of weight gain (114Trusted Source115Trusted Source).

In women, short sleep duration is consistently linked to increased waist size, compared to those who get a good night’s sleep (116Trusted Source117Trusted Source).

Similarly, sleep-deprived people are up to 55% more likely to become obese (114Trusted Source118Trusted Source).

Luckily, shifting sleep duration from shorter lengths to healthier lengths has been shown to help eradicate these effects (119Trusted Source).


Those who sleep too little are much more likely to gain weight and have increased waist circumference, compared to normal sleepers.

23. Try Intermittent Fasting

Intermittent fasting is an eating method in which you rotate between eating and fasting for specific amounts of time.

The most popular intermittent fasting approaches are doing a 24-hour fast two to four times per week or a 16:8 fast, where you restrict your eating window to eight hours each day, often between lunch and dinner.

Generally, this makes you eat fewer calories overall without having to consciously think about it.

While intermittent fasting has only been shown to be as effective as regular, daily calorie restriction at reducing tummy fat, many people find intermittent fasting to be easier to stick to than traditional weight loss diets (120121Trusted Source122Trusted Source123Trusted Source).


Intermittent fasting generally makes you eat fewer calories with little effort by restricting your “eating window.” It’s effective at reducing tummy fat and may be easier to stick to than traditional weight loss diets.

24. Eat Fatty Fish Every Week or Take Fish Oil

It is generally recommended to eat fatty fish once or twice per week.

Fatty fish is very healthy and rich in essential long-chain omega-3 fatty acids and good-quality protein (124Trusted Source125Trusted Source).

Protein has been shown to help with weight loss, and studies have suggested that omega-3 fatty acids may also help reduce the accumulation of fat in the liver and abdominal cavity (126Trusted Source127Trusted Source128Trusted Source129Trusted Source).

If you don’t like eating fatty fish, you can get long-chain fatty acids from fish oil or fish oil supplements.

The long-chain omega-3 fatty acids from fatty fish may help reduce the accumulation of fat around your waist.

25. Limit Your Intake of Added Sugar

Added sugar is linked to most of the common diseases in society today, including heart disease, type 2 diabetes and fatty liver disease (130Trusted Source131Trusted Source132Trusted Source).

The intake of added sugar is way too high in most societies, and Americans eat about 15 teaspoons of added sugar daily (133).

Studies have shown a direct link between high intake of added sugar and increased waist size, especially in people who drink sugar-sweetened beverages (134Trusted Source135Trusted Source136Trusted Source).

Added sugar is hidden in various foods, so it is very important to read the ingredient lists on foods.


Added sugar has a direct link to increased waist circumference, especially in those who regularly drink sugar-sweetened beverages.

26. Replace Some Fat With Coconut Oil

Coconut oil contains a unique combination of fatty acids. It is one of a few foods that is rich in medium-chain triglycerides (MCTs).

Studies have shown that replacing some dietary fat with MCTs may increase energy expenditure and make you feel fuller (137Trusted Source138Trusted Source139Trusted Source140Trusted Source).

What’s more, coconut oil has been shown to more effectively reduce waist size than other types of fat (141Trusted Source142Trusted Source).

Keep in mind that coconut oil is still fat with 9 calories per gram. Therefore, it is important not to just add coconut oil to your diet, but rather replace other sources of fat with it.

Coconut oil is rich in medium-chain triglycerides. Replacing other fats with coconut oil may increase your energy expenditure, make you feel full and reduce your waist circumference.

27. Strengthen Your Core

Crunches and other abdominal exercises can benefit both your overall health and appearance.

By doing regular core exercises, you strengthen and add mass to your abdominal muscles, which may prevent back aches that result from weak posture.

A strong core will also improve your posture and prop up your spine, allowing you to appear taller and more confident.

Furthermore, core exercises help you strengthen the muscles that ultimately hold in your belly, making you appear leaner.

Aim to do core exercises that engage all your core muscles, such as planks or Pilates roll-ups.


By strengthening your core, you are training the muscles that hold your stomach in. By having well-trained abs, you will appear taller, more confident and leaner.

28. Drink (Unsweetened) Coffee or Green Tea

Unsweetened coffee and green tea are among the healthiest beverages in the world.

Drinking coffee has been shown to increase the number of calories you burn by about 3–11% (143Trusted Source144Trusted Source145Trusted Source).

Similarly, drinking tea or taking green tea extract supplements has been shown to increase fat burning up to 17% and calorie expenditure by 4% (146Trusted Source147Trusted Source148Trusted Source149Trusted Source).

This includes green tea, black tea and oolong tea.

Most importantly, studies in animals and humans have shown that drinking coffee and tea may reduce the risk of accumulating belly fat, helping you reduce your waist size (150Trusted Source151Trusted Source).


Drinking unsweetened coffee or tea may increase your fat burning and reduce your waist size.

29. Don’t Drink Too Much Alcohol

Alcohol contains seven calories for each gram, which partly explains why alcoholic drinks tend to be loaded with liquid calories.

Ounce for ounce, beer contains a similar number of calories as a sugary soft drink, while red wine contains a whopping twice that amount (152153154).

Although moderate drinking is unlikely to affect weight gain, heavy drinking is linked to increased weight gain, especially around your midsection (155Trusted Source156Trusted Source157Trusted Source).

If you want a flat stomach, you should aim to reduce or skip the alcoholic drinks.


Heavy alcohol consumption may contribute to weight gain, especially around your midsection.

30. Sneak Extra Activity Into Your Day

You can easily sneak extra activity into your day by increasing the amount of non-exercise activity you do.

This involves walking, standing, fidgeting, moving around and basically everything other than exercise training, sleeping and eating (158Trusted Source).

Studies have shown that just standing, fidgeting or walking around can increase the calories you burn by five- to six-fold, compared to sitting still (159Trusted Source160Trusted Source).

One study suggested that fidgeting, walking and standing could burn up to 2,000 extra calories per day, depending on your weight and activity level (160Trusted Source).

Make it your goal to walk around while talking on the phone, stand up regularly, work at a standing desk or take the stairs whenever possible.


Increasing the amount of non-exercise activity you do may significantly increase the number of calories you burn on a daily basis.

Take Home Message

As you can see, there are many strategies that can help you achieve your goal of a flat stomach.

By incorporating some of the tips mentioned above into your daily routine, you may get to see your six pack sooner than later.

Keep in mind that it may take some time and effort, but will all be worth it in the end if done properly.
