High fibre diet for better bowel health and balanced body weight

Fibre is a powerhouse when it comes to your health and it’s a strong contender in the weight loss field too. A high fibre diet bucks the trend for low-carb dieting, but it has so many benefits, you would be crazy to pass it by.

What is fibre?

Fibre is a complex carbohydrate that comes from plant-based sources, it takes a long time for the body to break fibre down (if at all). Fibre comes in two types soluble and insoluble.

Soluble fibre, as the name suggests will dissolve in water and forms a gel-like substance that promotes satiety and slows gastric emptying – this keeps you feeling fuller for longer. Soluble fibre has also been shown to reduce cholesterol levels, reduce insulin resistance and works to reduce chronic inflammation and metabolic disorders.

Insoluble fibre is fibre that is not water-soluble and tends to be difficult for the body to break down. Some insoluble fibre may pass through your digestive system completely undigested. This type of fibre attracts water to the colon and bulks your stools, allowing you to pass them easily. This is why fibre is associated with easing constipation and good bowel health.

Fibre can be found in fruits and vegetables and grains and cereals. We usually find both soluble and insoluble fibre together in varying amounts.

How can a high fibre diet help you lose weight?

The gel-like substance formed from soluble fibre slows the emptying of your gut. This means that food travels through the digestive system slowly, leaving you feeling fuller for longer.

Insoluble fibre adds bulk to your food and is difficult to digest. This partial or non-digestion of insoluble fibre usually means very little energy is released from food so your stomach feels full with little calorie consumption.

Fibre has also been shown to reduce insulin resistance. Complex carbohydrates take longer to digest than simple carbohydrates. This results in a slower release of energy, which promotes a steady and controlled release of insulin rather than the spikes associated with sugar and refined carbohydrate consumption.

When it comes to weight loss, vegetables are by far one of the lowest calorie, high-fibre options. They are also nutrient-dense providing you with valuable vitamins and minerals. If you are looking to lose weight, focus on including lots of vegetables every day.

  • Weight regulation and healthy BMI
  • Reduced cholesterol
  • Improved cardiovascular health

How can I eat more fibre?

Fibre is found in fruits and vegetables, cereals, and grains. Avoid eating processed versions of these foods and try to cook these fast or eat them raw if you can.

Great examples of high-fibre foods:

  • Oats and cereals.
  • Raw vegetables for snacking and cooked vegetables (quick cook as cooking breaks down fibre).
  • Multi-vegetable salads.
  • Fruit salad and whole fruits.
  • Wholegrains such as bulgar wheat, brown rice, buckwheat, barley.
  • Wholegrain crackers.
  • Beans and pulses.
  • Nuts.
  • Baked potato.
  • Vegetables.
  • Avocado.

Now that you are aware of the amazing health benefits of a high fibre diet and how it can help you manage your weight, you can see why these foods form the foundation of any great healthy eating programme. If you are not currently eating many of these foods, it is a good idea to increase them gradually, as a sudden increase in fibre can be a shock to the digestive system, which may cause you more frequent trips to the bathroom. Take your time and find the high-fibre foods you like most to create your healthy eating plan.
