Doctor explains: How these 3 types of fibre help with weight loss

Fibre is more commonly known as the secret weapon for weight loss, but did you know there are different types of fibre, each with its own role in supporting a healthy body? UK-based NHS surgeon Dr Karan Rajan

recently shared in an Instagram video that to maintain optimal gut health and aid weight loss, people should consume three different types of fibre—soluble fibre, insoluble fibre, and resistant starch.

These fibres not only help with digestion but also play an important role in managing weight, reducing inflammation, and keeping the gut healthy. Here’s all we need to know about what each type does and how it can support weight loss.

Soluble fibre

Soluble fibre dissolves in water, forming a gel-like substance in the . This helps slow down digestion, makes us feel full for longer, and prevents overeating.

How it helps with weight loss:

  • Increases satiety, reducing cravings.
  • Feeds gut bacteria, which produce anti-inflammatory compounds.

Where to find it: Oats, apples, chia seeds, flaxseeds, lentils, and psyllium husk.


Insoluble fibre

does not dissolve in water and acts like a natural brush, cleaning out the digestive system. It helps prevent constipation and promotes regular bowel movements.

How it helps with weight loss:Adds bulk to stool, preventing bloating and constipation.Moves food quickly through the digestive tract, supporting a healthy metabolism.Helps in reducing calorie absorption.

Where to find it: Whole grains, nuts, seeds, leafy greens, and the skin of fruits like kiwis and apples.
