Fibre remains one of the most crucial yet frequently overlooked nutrients in our daily diet, playing multiple vital roles from maintaining digestive wellness to regulating blood sugar and controlling appetite. Despite its importance, many people fail to consume adequate fibre, leading to various health complications that extend far beyond the commonly known issue of constipation.
The Hidden Early Warning Sign of Fibre Deficiency
While most people associate low fibre intake with constipation, Dr Saurabh Sethi, a renowned gastroenterologist trained at premier institutions including AIIMS, Harvard, and Stanford Universities, recently highlighted on Instagram that the earliest indicator of fibre deficiency is actually feeling hungry shortly after finishing meals. This occurs because fibre slows down digestion and promotes satiety. Without sufficient fibre, food moves through the digestive system too quickly, leaving individuals unsatisfied and prompting frequent hunger signals that can disrupt nutritional balance and overall health.
Beyond Constipation: Other Critical Signs You're Not Getting Enough Fibre
Unexplained Weight Gain and Increased Appetite
Fibre's role in appetite regulation is profound. It creates a feeling of fullness that helps prevent overeating and unnecessary snacking. When fibre intake falls short, people often find themselves reaching for high-calorie, low-nutrient foods between meals, leading to gradual weight gain. Dr Sethi emphasizes that feeling hungry soon after eating represents one of the initial red flags of inadequate fibre consumption. Incorporating fibre-rich foods like fruits, vegetables, whole grains, legumes, and nuts can effectively manage these sudden hunger pangs and support healthy weight maintenance.
Elevated Cholesterol and Cardiovascular Risks
Soluble fibre, which dissolves in water to form a gel-like substance, plays a critical role in cholesterol management by reducing its absorption into the bloodstream. When dietary fibre remains consistently low, cholesterol levels can rise, increasing long-term cardiovascular risks. Research published in PubMed Central confirms that regular consumption of soluble fibre can significantly lower both total and LDL cholesterol levels, thereby reducing heart disease risk. Even modest daily amounts of fibre provide measurable benefits for heart health, making adequate intake a simple yet powerful preventive measure.
Blood Sugar Fluctuations and Energy Dips
Fibre serves as a natural regulator of blood sugar by slowing sugar absorption into the bloodstream, preventing the rapid spikes and crashes that lead to fatigue and concentration difficulties. For individuals with diabetes or insulin resistance, maintaining stable blood glucose levels becomes particularly crucial. Insufficient fibre intake can disrupt this balance, causing energy fluctuations throughout the day. Ensuring adequate fibre consumption helps maintain consistent energy levels and supports overall metabolic health.
Haemorrhoids and Digestive Discomfort
Chronic constipation resulting from low fibre intake can lead to the development of haemorrhoids – swollen veins around the rectum and anus. Straining during bowel movements places excessive pressure on these veins, causing pain, itching, and sometimes bleeding. Insoluble fibre from whole grains, vegetables, and nuts helps soften stools, reduce straining, and protect against haemorrhoid formation.
Increased Food Cravings and Poor Satiety
A diet lacking sufficient fibre often triggers cravings for sugary and processed foods. Since fibre slows digestion and promotes fullness, its absence disrupts normal hunger hormone regulation. The body consequently signals hunger more frequently, leading to overeating and poor food choices. Consistently including fibre-rich options like fruits, vegetables, legumes, and seeds can help control these cravings and improve long-term appetite management.
How to Ensure Optimal Fibre Intake for Better Health
Preventing fibre deficiency requires incorporating diverse fibre-rich foods into your daily meals. Excellent sources include fruits such as apples, berries, and pears; vegetables like spinach, carrots, and broccoli; whole grains including oats, brown rice, and quinoa; and legumes such as lentils, chickpeas, and various beans. Nuts and seeds also contribute valuable fibre. Health experts recommend approximately 25 grams of daily fibre for women and 38 grams for men. Consistently meeting these targets supports gut health, controls appetite, stabilizes blood sugar, and reduces the risk of long-term digestive and cardiovascular issues.
