If you're Googling "flat stomach foods," the likelihood is you're looking to lose stomach fat and want to know what foods to be piling your plate with to make sure you're getting the best results.
FYI, there is no such thing as a flat stomach food per se - rather, there is a range of nutrient-dense foods high in antioxidants and micronutrients that are key to boosting your overall health which may help you stay full while maintaining the all-important calorie deficit key for any fat loss (more on that later).
While there's no doubt there's unnecessary societal pressure for women to lose weight, excess stomach fat, in particular, can pose a high health risk. Just last year, a Journal of the American Heart Association study found that, for women, carrying excess stomach fat, rather than carrying weight all over, could be worse for your heart health.
Studying 500,000 people aged 40 to 69 in the UK, the research found that women who carried more stomach fat had a 10% to 20% greater risk of suffering from a heart attack than those who carried weight all over.
Visceral fat, otherwise known as the fat that lies below your skin and cushions your organs, can actually play a part in a whole variety of harmful health conditions, including an increased risk of cardiovascular disease, type two diabetes, and breast cancer.
Keen to lose a little stomach fat? Know this: if you eat healthily most of the time and don't have a perfectly flat stomach, all three experts confirm you likely have nothing to worry about and don't need to lose fat. However, if you are keen to make some lifestyle changes and think losing weight will boost both your physical and mental health, qualified experts are your best starting point. Weight loss is a very personal journey and will vary from individual to individual.
Flat stomach foods: so, do they exist?
First things first: there are a whole load of things that affect how women carry fat, and particularly, how we carry stomach fat. There are factors you can't control, like your genetics, hormones, and metabolism, and then, of course, the things you can mix up, such as your daily movement and what foods you're eating.
So, can what foods you eat affect your levels of stomach fat? Sure - but it's not quite called that. "While some foods are more nutritionally dense and beneficial for your overall health than others, I wouldn't say there's such thing as a "flat stomach food," shares Lauren Windas, registered nutritionist at Ardere.
"However, in order to achieve a flat stomach and the body composition you desire, your focus should be on eating in a healthy calorie deficit and enjoying a balanced nutritious diet, as well as strength training, running, or exercising regularly," she goes on.
Flat stomach foods: 15 that could help with weight loss
The experts advise aiming for nutritionally dense foods and meals that are also high protein.
Why? Because these are the foods that'll not only benefit your overall health, but further help with weight loss, if eaten in an all important calorie deficit. More on that, below.
1. Green leafy vegetables
Windas recommends kale, spinach, and chard. "While being low in calories, these vegetables are packed full of quality nutrition; plenty of vitamins and minerals that are supportive for our immune system and our overall health," she shares.
Nutritionist Lorna Driver-Davies from NutriCentre agrees, adding that eating plenty of greens will help by keeping your bowels moving. Her favourites are broccoli, green beans, and spinach.
Windas also recommends you include plenty of protein in your weight loss plan to help keep you satiated for long periods of time. "Eggs are high in protein and also very cost-effective," she explains.
Nutritionist doctor Marilyn Glenville adds here that the research agrees. "Research showed that leucine, one of the essential amino acids found in eggs, can help with weight loss by stabilising blood sugar levels and encouraging the body to shed fat," she shares.
Keen to up your intake of vegan protein? Here are some examples of vegan protein sources to include in your diet, if you follow a plant based diet. Not sure what protein actually is? Our guide explains.
Aka, is porridge good for you if you're looking to lose weight? Oh yes. "Oats are a great staple to begin your day with," Windas explains. The nutritionist explains that they're a great source of fibre, which keeps you fuller for longer and helps to stabilise your energy levels for long periods of time. "They make an ideal choice for those looking to lose weight because you remain satiated and therefore don’t tend to snack throughout the rest of your morning," she adds.
Remember to add a form of protein - think yoghurt, protein powder, nuts or seeds - for full muscle repair and satiety. Still stuck for ideas? Our round-up of the healthy breakfast ideas might help.
Fun fact: Windas always recommends dusting some cinnamon over porridge or a snack, particularly for those who have a sweet tooth. Why? Well, because cinnamon has been shown to reduce sugar cravings and has a naturally sweet taste itself, helping to curb that sweet tooth and consumption of energy-dense high sugar foods.
Bloat a lot? "It's also great for digestion, is anti-fungal, and will keep your sugar cravings at bay," adds Driver-Davies. Don't miss our explainer on what causes bloating, if that's you.
Berries are a great go-to fruit because you can enjoy them for snacking or adding to a slice of toast or porridge, explains Windas.
"Blueberries, blackberries, raspberries and cranberries are all very high in antioxidants and are a low GI fruit," she explains. "This means they score low on the glycaemic index (GI) and metabolise into sugar in the bloodstream much slower than other fruits." Neat.
Healthy snack ideas never looked so simple.
6. Wholemeal bread
Carbs aren't the enemy and, ultimately, provide your body with the energy it needs to survive. "Wholegrain alternatives are arguably better than white, as they release energy more slowly," says Glenville.
7. Healthy fats
Think avocado, chia seeds, flax, olive oil and nuts.
"Getting enough good oils in your diet can be helpful for reducing bloating - they help keep your bowels moving by lubricating your stools," explains Driver-Davies.
"Fish is good quality protein," explains doctor Glenville. "It slows down the rate that the stomach processes food and delays the passage of the carbohydrates through it," she shares.
Did you know? As soon as you add a protein (be it animal or vegetable) to a carbohydrate, you change it into a slower releasing carbohydrate, which will keep your sugar levels steady and energy up.
No, you don't need to eat it on the reg, but celery is a great veg to snack on and include in meals, if you like it, as it's high in potassium, which can help ease bloating, explains Driver-Davies.
As above on the healthy fats point, nuts can be a good food to include in your diet if you're looking to lose weight as they contain - yep, you guessed it - healthy fats.
Just be careful with portion size. They are high calorie, so can halt weight loss efforts if overeaten.
Did you know? Eating probiotic-rich foods is key for a healthy gut, which in turn, is key for maintaining a healthy weight, explains Driver-Davies. "Try live yoghurts and fermented foods like sauerkraut, kefir, kimchi and miso," she recommends.
Rather supplement yours? Don't miss our guide to the best probiotics for women.
"Certain herbs like peppermint and ginger can aid the digestive system," explains Driver-Davies.
Not sure why this is important for weight loss? Well, simply, because if your body isn't digesting food properly, your whole system can get out of balance, contributing to bloating and difficulty losing weight, shares the nutritionist.
These weight loss tips from a qualified professional further highlight the most basic need-to-knows if you're looking to lose weight.
Asparagus is a low-calorie and high-nutrient food, just like the green veg mentioned above. It's also high in both vitamin E and C, key for maintaining a healthy immune system.
Did you know? Fennel has been used to treat gastrointestinal issues in Chinese, Indian, Egyptian and Greek medicine for centuries, shares doctor Glenville. "The tiny seeds are great for stimulating digestion and their anti-inflammatory properties help to relax contracted intestinal muscles, which can contribute to keeping your stomach looking flat," she shares.
Aside from being a vitamin C food, lemons are a great way to battle fluid retention, which can leave you feeling swollen. Try adding a slice of lemon to hot water in the morning for an easy way to get more of the fruit into your diet.
Bottom line: You'll be most successful if you opt for a weight loss plan that works for you, includes foods you actually enjoy, and doesn't leave you feeling deprived.
How do I create a healthy calorie deficit and lose stomach fat?
Weight loss, once you get your head around it, is actually a pretty simple formula. According to Windas, making sure your body is using more energy than you are consuming is the simplest way to lose weight.
This is called a calorie deficit.
"A healthy calorie deficit will allow you to acquire enough calories to keep the body well," Windas shares. She'd recommend a deficit of 500 calories daily. "That means women who consume the NHS guideline of 2000 calories a day to maintain their weight would want to consume 1500 calories a day to be in a deficit," she explains.
Don't dip any lower or you'll struggle with focus, lacking energy levels and risk malnutrition, she warns.
I eat healthily but don't have a flat stomach. Do I need to worry?
Short answer: probably not.
While this will vary on a case-by-case basis, generally speaking, if you know you're eating well and still have a slightly rounded stomach, you're all good.
"Remember, being healthy is not solely defined by having a flat stomach," Windas explains. She points out that there are people who have flat stomachs that aren’t healthy but simply have a fast metabolism. "Remember, what you look like is not a marker of health status."
