Fibre, also known as roughage, is important for your overall health. A person needs fibre for digestion, weight control, to manage cholesterol and blood sugar and to strengthen bones. However, have you ever wondered if there is a right time to consume fibre and its supplements?

How Much Fibre Does One Require In A Day?The recommended daily intake of fibre is 25 grams per day for women and 38 grams per day for men. However, some experts estimate as much as 95 per cent of the population doesn’t ingest this much fibre, and may require fibre supplements due to dietary and age restrictions. On the other hand, ingesting too much fibre, while uncommon for most people, can lead to several uncomfortable digestive and health-related side effects.

Does Timing Matter?

No, Fibre can be consumed throughout the day. However, one needs to be careful while consuming fibre supplements. There is limited research which underscores that timing does matter. Many studies suggest taking fibre supplements at meal times can help your body absorb them better and may make them more effective. No matter when you consume the supplements, consistency is the key. Irregular intake of fibre supplements can trigger discomfort like bloating, gas, and changing bowel patterns.

Should You Take It With Food?

Most research suggests that taking fibre supplements with food can help improve digestion and prevent digestive discomfort. Taking fibre before a meal may help control your appetite and help you feel full. Taking it after a meal may support digestion by bulking up your stool. Some people may experience discomfort when taking a fibre supplement too close to mealtimes. Unless your healthcare provider or registered dietitian says otherwise, consider taking fibre at least 30 minutes before or after eating. You should also drink plenty of water.

What Happens When You Consume Excessive Fibre?

Consuming excess fibre or its supplements can result in bloating. Insoluble fibre found in whole grains, vegetables, and nuts, can increase gas production during digestion, causing bloating. It can also cause abdominal pain. Too much fibre can cause the digestive system to work harder than usual, leading to abdominal cramping or discomfort. This occurs as fibre moves slowly through the intestines, increasing the workload on the digestive muscles.

Flatulence (Gas) is another issue. Fibre-rich foods, especially legumes, vegetables, and grains, produce gas as they break down in the intestines. This is a normal byproduct of digestion, but excessive fibre can lead to more gas than the body can comfortably handle.

Soluble fibre, found in oats, beans, and fruits, absorbs water, which can lead to overly loose stools or diarrhoea, as excess water may remain in the intestines. On the flip side, an abrupt increase in fibre without enough water intake can cause constipation. Fibre requires water to move smoothly through the digestive tract, so dehydration or insufficient hydration can lead to harder stools.

High-fibre foods tend to be bulkier, and consuming too much can lead to temporary weight gain due to water retention and slower movement of fibre through the digestive tract. Additionally, fibre can make you feel fuller, causing temporary bloating. Excessive fibre intake can cause a blockage in the intestines, particularly in people with Crohn’s disease or other inflammatory bowel conditions. Since fibre isn’t fully broken down, it can accumulate, potentially causing an obstruction.

Fibre helps slow down the absorption of sugar, leading to more stable blood sugar levels. However, too much fibre may lower blood sugar too drastically, which is a concern for people with diabetes who may be monitoring their blood sugar levels closely.

New Delhi: The sattvic diet traces back to its roots in ancient Ayurvedic knowledge and is based on the philosophy of Sattva, which stands for harmony, balance, and purity. It places a focus on whole, fresh, and minimally processed meals that support both physical and mental vigour. This "yoga of eating" becomes a biological requirement for preserving homeostasis in the intense summer heat.

Dr. Narendra K. Shetty, Chief Wellness Officer, Kshemavana Naturopathy and Yoga Center, Bengaluru, in an interview with Health and Me, spoke about the science behind following a sattvic diet in summer.

Core principles of sattvic foods

In sattvic diets, foods that are rich in prana (life-force energy), such as seasonal fruits and vegetables, grains, nuts, and seeds, take precedence. "Tamasic" (heavy) foods such as meat and processed sugars should be avoided, as they can weigh the body down and dull the mind. "Rajasic" (stimulating) foods such as caffeine and chili are also avoided.

Scientific basis of nutrition and digestion in summer

According to science, the body's internal thermostat works harder in the summer. Agni (digestive fire) naturally decreases in high ambient temperatures. In order to promote cooling through perspiration, blood flow is frequently redirected from the digestive tract towards the skin's surface. The body struggles to break down dense nutrients with decreased enzymatic efficiency when complex, heavy proteins are consumed during this period, leading to metabolic stress.

Summer physiology: Why light eating matters

A shift towards thermoregulation is required during summer. Heavy meals cause diet-induced thermogenesis, in which heat is produced internally during digestion. By consuming "light" foods, we lower this internal heat load. Because sattvic meals are high in fibre and water, they require less energy to digest, allowing the body to focus on staying cool rather than working on digestion.

Sattvic diet benefits in hot weather

1. Hydration: Electrolyte balance is maintained due to naturally high water content.
2. Energy: Provides a steady release of glucose without the "crash" caused by heavy fats.
3. Mental calm: Reduces agitation and fatigue brought on by heat.

Key sattvic foods for summer

To remain "bright," one should focus on the following:

1. Cooling fruits like grapes, watermelon, and muskmelon
2. Hydrating vegetables like cucumber, zucchini, and bottle gourd
3. Herbs and dairy: fresh buttermilk (chaas), coriander, and mint

Eating light is not just a lifestyle choice but a scientific response to our biological needs. By adopting a sattvic perspective, we ensure that we not only survive but also thrive in the heat by aligning our internal environment with the external season.

New Delhi: Many people have an irresistible urge to eat something sweet right after a meal. Although this habit is often written off as a preference or some sort of cultural habit, new scientific data suggest that post-meal sugar cravings hint at something serious: a metabolic imbalance. In an interaction with Health and Me, Dr. Aravind Badiger, technical director, BDR Pharmaceuticals, decoded the intricate science behind a sweet tooth, and as per the expert, it is because of a nutrient deficiency.

The Blood Sugar–Insulin Connection

Upon eating a meal high in carbohydrates, blood glucose levels rise. This triggers the release of insulin from the pancreas. If the meal is low in protein and fibre, insulin spikes more quickly, making the blood sugar drop sooner. This drop then triggers a signal to the brain that the body needs quick fuel, often interpreted as a desire for something sweet. This cycle, a rapid rise and fall in blood glucose levels, is known as reactive hypoglycaemia, one of the common reasons people feel the need to have dessert after meals.

The Missing Nutrient: Protein

Protein helps to regulate blood sugar levels after a meal. In addition, adequate protein:

1. Slows digestion and glucose absorption
2. Reduces insulin spikes
3. Improves satiety by elevating GLP-1 and peptide
4. Modulates hunger signals via the hypothalamus

When a meal is low in protein, the body does not get those satisfying signals it is used to receiving. This drives the brain to find sources of energy that work quickly—sugars. In fact, clinical nutrition studies indicate that balanced meals containing at least 20–30 grams of protein reduce post-meal sugar cravings significantly.

The Gut–Brain Axis Influence

Your gut microbiome also plays an important role. Meals high in simple carbohydrates encourage the growth of gut bacteria that thrive on sugar. Evidence shows that low-protein diets shift the balance of gut microbes, which further increases sweet cravings. Thus, the less protein you consume, the more your microbiome may “push” you towards sugary foods.

Emotional and Behavioural Factors

For some people, dessert cravings are psychologically conditioned. The body learns over time to attach a reward to the end of a meal by releasing small amounts of dopamine. But even in such cases, stabilisation of blood sugar through adequate protein intake reduces the emotional component of cravings.

How to Reduce Sugar Cravings After Meals

1. Include 20–30 g of protein in each meal, including eggs, dal, legumes, tofu, fish, lean meats, and dairy products.
2. Choose complex carbohydrates over refined sugars.
3. Add vegetables high in fibre to delay the absorption of glucose.
4. Drink plenty of water – mild dehydration produces symptoms similar to sugar cravings.
5. Sleep 7–8 hours; sleep deprivation increases the hunger hormone ghrelin.
6. Do not conclude every meal with sugar. It is a conditioned response and needs to be broken gradually.

A growing body of research is raising fresh concerns about how deeply smartphones are shaping not just attention spans, but also eating habits and self-image among young people. A recent study published in the Journal of Medical Internet Research has found that excessive and compulsive smartphone use may significantly increase the risk of disordered eating behaviors in adolescents and young adults.

Smartphones Could Turn Into Dependency

The study centers on what researchers describe as Problematic Smartphone Use, or PSU. This is not simply spending long hours on a device, but a pattern marked by psychological dependence, difficulty cutting back, and anxiety when separated from the phone. Unlike casual or necessary screen time, PSU begins to interfere with daily functioning and emotional well-being.

To understand the scale of the issue, researchers analyzed 35 studies involving more than 52,000 participants, with an average age of 17. The findings paint a worrying picture. Young individuals who showed signs of smartphone dependency were more likely to engage in unhealthy eating behaviors. These included emotional overeating, uncontrolled food consumption, and patterns resembling food addiction, even in the absence of a formal diagnosis.

A 7-hour Tipping Point

One of the most striking findings of the study is the identification of a potential threshold. The risk of disordered eating rose significantly among those who used their smartphones for more than seven hours a day. While this may not seem unusual in an increasingly digital world, the study suggests that crossing this limit could have tangible effects on both mental and physical health.

A key factor driving this link appears to be body image dissatisfaction. Constant exposure to curated and often unrealistic images on social media platforms can distort perceptions of beauty and self-worth. Over time, this can lead to unhealthy comparisons and a strained relationship with food.

More Than Screen Time

Importantly, the researchers highlight that not all screen time carries the same risk. The distinction between general use and PSU is crucial. It is the compulsive nature of usage, accompanied by withdrawal symptoms and loss of control, that is most strongly associated with negative outcomes.

The study does not claim that smartphones directly cause eating disorders. Instead, they act as a contributing factor that can amplify existing vulnerabilities, particularly in impressionable age groups.

Wider Mental Health Implications

Beyond eating behaviors, excessive smartphone use has also been linked to anxiety, depression, lower physical activity levels, and reduced productivity. These interconnected issues suggest that digital habits are playing a broader role in shaping overall health.

What Could Help?

Experts suggest that small, consistent changes can make a difference. Setting clear boundaries for screen time, taking regular breaks, and engaging in offline activities such as sports or hobbies can help restore balance. Encouraging mindful use of technology, especially among younger users, is increasingly being seen as an important step in both prevention and intervention.

As smartphones continue to be an inseparable part of daily life, the study highlights the need to look beyond convenience and consider their deeper psychological impact.
