Fibre: The support you need for weight loss
WHEN it comes to weight loss, people often focus on cutting calories or ramping up workouts. But one simple, often overlooked tool can make the process easier and more sustainable, and that’s including fibre.
Far from being just a digestive aid, fibre plays a powerful role in controlling hunger, balancing blood sugar, improving gut health, and even influencing fat metabolism.
“By maxing out your fibre intake through both whole foods and, when needed, supplements, you can set up your body to burn fat more efficiently, feel full longer, and avoid the blood sugar swings that derail healthy eating plans,” said dietician Claudhia Ashley.
She said maxing out your fibre, whether through food or supplements, can give your weight loss goals a powerful assist because fibre influences several key systems involved in hunger, digestion, and metabolism.
Here’s how:
Appetite control & satiety
Slower digestion: Fibre adds bulk and slows stomach emptying, keeping you full longer.
Reduced cravings: Soluble fibre, in particular, helps stabilise blood sugar, preventing the sharp highs and lows that trigger snacking.
Hormonal effects: High-fibre diets can increase satiety hormones and lower the hunger hormone.
Calorie dilution without hunger
Fibre is essentially non-digestible carbohydrate — it adds volume without adding usable calories.
“Meals rich in fibre tend to be more filling per calorie, meaning you can eat larger portions for fewer total calories,” Ashley said.
Improved blood sugar control
“Soluble fibre slows the absorption of glucose, flattening blood sugar spikes,” Ashley said. “More stable blood sugar means fewer insulin surges and less likelihood of fat storage.”
She said fibre supplements can help, but food comes first. The best food sources are fruits, vegetables, beans, lentils, whole grains, nuts and seeds.
“It’s not a magic bullet, but it’s one of the most sustainable, evidence-backed dietary tweaks you can make,” Ashley said.
“Ensure that you increase fibre gradually to avoid gas and bloating. And drink plenty of water, because fibre without fluids can cause constipation.”
