  "account": "Fibre's health benefits often take time to manifest, according to NHS surgeon Dr Karan Rajan. In an Instagram post, he explained that even if the effects aren't immediately perceptible, there is indeed beneficial activity occurring within the body. Research has shown that gut microbiome composition can begin to adapt and capitalize on fibre intake within 24 to 48 hours. Comparing low fibre and high fibre diets, spikes in beneficial bacterial species have been observed around the 24 to 48 hour mark.\n\nDr Adithya V. Naragund, a senior consultant in GI & HPB Surgery at Cytecare Hospitals, Bengaluru, confirms that once fibre consumption is increased, gut bacteria start to ferment and adapt rapidly. \"Within a day or two, this shift can result in softer, more regular stools, less straining, and in some cases, a reduction in constipation,\" he stated. These early microbial changes not only ease digestive discomfort but also lay the groundwork for enhanced metabolism and improved nutrient absorption.\n\nHowever, the pace at which individuals notice improvements can vary significantly. Factors such as genetics, hydration, physical activity, and stress levels all influence how quickly one's body responds to dietary fibre. Someone adhering to a balanced, plant-rich diet, drinking adequate water, and maintaining a generally healthy lifestyle is likely to experience quicker benefits in areas like digestion, mood, and skin health.\n\nDr Naragund recommends that adults aim for at least 25 to 30 grams of fibre daily, sourced from a diverse range of foods. This daily intake, when maintained over the long term, is strongly linked with a reduced risk of serious health conditions like bowel cancer, heart disease, and type 2 diabetes.",
