HAVING a flat belly is the holy grail for the insta-famous, but for most, it seems to be an unattainable goal. If you’re always dieting, forever crunching, and unmotivated to see it through, here’s one small change that can shrink your waist and get you significantly healthier, finds a new study.
The researchers examined data from 1441 participants across seven European countries and found diets higher in wholegrains and fibre were the top dietary factors linked with less belly fat and a lower BMI.
“This study highlights the importance of healthy diet patterns, rather than focusing on eliminating specific foods. Switching refined grains to wholegrains, and choosing higher fibre foods could be important for maintaining a healthy waistline. Encouraging healthy behaviours may be even more effective than discouraging unhealthy ones,” says Nutrition Research Australia Director, Dr Flavia Fayet-Moore.
The surge of interest in higher protein or fat diets (e.g. paleo, low-carb, ketogenic), or grain avoidance (e.g. gluten free) has many Australians removing ALL carbohydrates — including grain foods — as a quick fix for weight loss. But when the diet is over and you want to keep the weight off, elimination of food groups is never the answer to long-term balanced diet. It’s simply not sustainable and not good for your health.
Currently, Australians only eat about between 21–25 grams of fibre—the parts of plants that can’t be digested—per day. That’s less than the 25 to 30 grams that’s recommended. Similarly, only a quarter of Australians are eating enough whole grains. And because fibre plays such a huge part in our overall health, falling short of the daily target not only means more chance of getting fat, but ups your disease risk, too.
How is fibre and weight loss related?
Anything that reduces our appetite can make us take in fewer calories without having to think about it. Fibre is believed to have this effect: it takes longer to digest, helps control blood sugar and insulin levels, and keeps us more satiated so that we eat less.
The best part about this diet advice is that it doesn’t involve piling your plate with more salad, carrots and celery sticks (although Australians could definitely do with eating more vegetables), but there’s also plenty of cereal fibre and wholegrains in rolled oats and many high-fibre breakfast cereals, and wholegrains (e.g. brown rice, corn, barley, grainy breads) that in fact give us more dietary fibre than any other foods, and are the leading contributors of fibre in Australian diet.
And we’re not talking truckloads: Aim to eat grain foods three to four times a day (or more depending on your activity levels), mostly those high in cereal fibre and whole grains. One serve is equivalent to 1 slice of bread, ½ cup cooked rice, barley, quinoa, ¼ cup muesli, 2/3 cup wheat cereal flakes.
Bottom line: Not all carbs are bad. Choose wholegrain over refined varieties and your belly will thank you for it as it shrinks.
