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.

Do foods impact our mood and how we feel? For some of us, cake makes us happy, for others, a bowl of salad. But, is there really a connection? For years, we have thought that foods like pizza, a cake, or something that is quick and can be made instantly makes us happy.

But experts argue that this belief is less science and more savvy advertising.

“People are like walking wallets to food companies,” Felice Jacka, Director of the Food and Mood Centre at Deakin University in Australia tells this to NPR. “They sell you this myth that eating these foods will make you feel good.”

In reality, these foods can mimic a short-lived high , a bit like champagne, she says. “Feels good in the short term, but the long-term impact is the opposite.”

How Does Food Shape Your Mood?

Over the past 15 years, Jacka and other researchers have built the field of nutritional psychiatry, exploring how diet influences mood and mental health. Their findings are clear: while some foods lift your mood and protect against depression, others do the exact opposite.

Ultraprocessed foods or UPFs, which packed with refined sugars, white flours and additives, fall firmly in the mood-draining category. People often feel anxious, irritable or lethargic a few hours after eating them.

Speaking to NPR, Dr Kara Margolis, a pediatric gastroenterologist at New York University tells that she sees this link regularly. “Some weekend mornings, I go to a diner and have a waffle. By 10 o’clock, I feel terrible,” she says.

Long-term patterns matter even more. “Large epidemiological studies show a 20% to 30% higher risk of depression when diets are high in ultraprocessed foods and refined carbohydrates,” Margolis adds.

At the same time, several controlled trials reveal that cutting these foods out and replacing them with whole, minimally processed foods helps reduce depression symptoms. The paradox? When people believe ultraprocessed foods make them happy, they tend to eat more of them.

The Gut–Brain Connection

If sugary treats aren’t true “happy foods,” then what is? Scientists are still mapping this connection, but one strong contender keeps emerging: whole grains.

“Whole grains seem to be particularly important,” says Jacka. Their power comes from fermentable fiber, which feeds beneficial gut bacteria. When these microbes digest fiber, they produce molecules that reduce inflammation, improve insulin sensitivity and strengthen gut-brain communication, all factors linked to better mood.

“Making the environment in your gut right for good bacteria not only can affect mood, but it can protect you from nearly every medical condition that’s been studied,” says Margolis, citing heart disease and diabetes among them.

As the holiday season approaches, what are the four ways one can eat food that makes us happy, but for a longer period of time.

Four Ways To Eat For a Happier Holiday Season

Cook at Home More Often

Jacka says there are two independent ways to influence mood through diet, and the first is: cut back on ultraprocessed foods.

That includes foods with artificial sweeteners, refined carbs, preservatives, emulsifiers (like xanthan gum or soy lecithin), and artificial flavors.

During the holidays, skip store-bought pies, pastries and fast-food burgers. Jacka suggests making a “beautiful flour-free cake using almond meal and honey. It’s still sweet, but much better for your mood.”

Make the Holidays Less ‘White’

The second strategy: increase whole grains.

Swap croissants and sugary cereals for oats or brown-rice congee. Choose corn tortillas over flour ones. Switch biscuits and white rolls for 100% whole-wheat versions. Even baking can be tweaked, use oat, barley or whole-wheat flour.

Add Beans and Lentils

Another powerful source of fermentable fiber is legumes.

“Your microbiome loves beans,” says Dr Meroë Morse of MD Anderson Cancer Center, as reported in NPR. Even a small amount, a quarter cup of cooked beans, can deliver a significant fiber boost.

Speaking to NPR, Hannah Holscher, microbiome scientist and dietitian at the University of Illinois Urbana-Champaign, recommends tossing beans or lentils into soups, curries or chili. Lentils cook quickly and are cost-effective, making them an easy daily addition.

Increase Slowly

Beans, lentils and dense whole grains can be intense for an unprepared gut. Holscher advises starting with small servings and increasing gradually. Soaking beans or trying different varieties may also help minimize bloating.

Other fermentable-fiber foods, chia seeds, berries, pears, apples, avocados and even unripe bananas, can round out your fiber intake.

The search for the perfect anti-ageing diet never seems to end. From intermittent fasting to keto plans, most options require discipline, calorie restrictions, or rigid meal routines. But a new trend, gaining attention worldwide and called ‘fake fasting,’ suggests you could reap the benefits of fasting without actually going hungry. And yes, experts are taking notice.

Recent research shows that “fake fasting” may provide similar age-reversing health effects as full fasting. Known as the fasting-mimicking diet (FMD), this approach is designed to imitate water fasting by affecting blood glucose, ketone levels, and other biomarkers.

Unlike traditional fasting, which means completely abstaining from food, FMD allows for a controlled intake of certain nutrients and follows a cycle: usually five days on the diet each month, with normal eating the rest of the time.

What Is The ‘Fake Fasting’ Diet Trend?

The FMD is a five-day plan that is high in unsaturated fats but low in calories, protein, and carbs, designed to mimic the effects of water-only fasting while still giving your body essential nutrients. The idea is to simulate fasting’s benefits, like targeting blood glucose and ketone levels, without going entirely without food.

During normal fasting, people consume nothing. In fake fasting, however, you eat small amounts of specific nutrients in cycles.

A study published in Nature Communications in 2024 outlined the diet’s benefits. Researchers highlighted that FMD is a five-day program rich in unsaturated fats, low in calories, protein, and carbohydrates, and structured to mimic a water-only fast while still supplying necessary nutrients, making it easier for people to complete.

Professor Valter Longo of the USC Leonard Davis School, senior author of the study, developed the diet. “This is the first study showing that a food-based approach, without requiring permanent dietary or lifestyle changes, can make people biologically younger, based on changes in both ageing and disease risk factors and a validated method by the Levine group to measure biological age,” Longo said.

Fake Fasting Diet: What Does Research Show?

In USC studies, participants went through three to four cycles of the fasting-mimicking diet, each followed by a return to regular eating. Typical meals included plant-based soups, nut bars, herbal teas, vegetable chips, and supplements packed with vitamins, minerals, and essential fats.

Key findings included:

• Reduced diabetes risk factors
• Lowered liver fat
• Improved ageing markers
• Better metabolic and immune function

Researchers suggested that limiting calories while following precise nutrient ratios may create an environment that supports cellular renewal.

Fake Fasting Diet: What To Eat During This Diet?

A standard FMD program is low in protein and carbohydrates but high in healthy fats. Typical foods include:

• Nut-based energy bars
• Light vegetable soups or broths
• Olives or kale chips
• Herbal teas
• Small portions of vegetables
• Low-glycaemic fruits like berries, pears, or apples

Can Fake Fasting Diet Slow Down Ageing?

During FMD, calories are cut to about 40–50% of normal daily intake, with protein and carbs restricted to trigger cellular and metabolic effects similar to water fasting. The diet relies on unsaturated fats, known to lower inflammation and support heart health. In the USC study, participants followed three to four monthly FMD cycles, each lasting five days, then returned to a normal or Mediterranean-style diet for the remaining 25 days.

While on FMD, participants consumed plant-based soups, energy bars, chips, drinks, and tea, along with supplements rich in vitamins, minerals, and essential fatty acids.

The study found that FMD lowered diabetes risk factors, reduced liver fat, slowed immune ageing, and decreased age-related health risks, effectively lowering biological age. “This is the first evidence from two clinical trials showing a reduction in biological age, along with rejuvenation of metabolic and immune function,” said Professor Valter Longo.

Who Should Avoid The Fake Fasting Trend?

Fake fasting is not for everyone. Some may experience:

• Fatigue or low energy during the five-day period
• Irritability or headaches
• Difficulty adjusting to reduced calories

It is not recommended for pregnant or breastfeeding women, underweight individuals, or anyone with chronic health conditions unless supervised by a professional. Experts stress consulting a doctor before making major dietary changes.

A new study has revealed that Gen Zs eat much more ultra-processed foods than we may think. Processed foods have saturated the market over the years, however, recent researches have revealed how these foods affect our health. But do you know who is most affected by this? The study, done by the Virginia Tech, showed that not only are gen Zs more likely to overeat, but most of their diet is also affected by processed foods.

Research suggests about 62% of their total calories come from these factory-made items. A new study from Virginia Tech warns that this high intake, especially when it leads to overeating, is a major concern for their future health.

How Much UPFs and Calorie Intake?

Researchers at Virginia Tech looked at 27 young men and women, aged 18 to 25. For the study, the volunteers followed two different eating plans:

High-UPF Diet

81% of the calories came from ultra-processed foods.

Junk-Free Diet

A whole-food diet with no junk food.

The diets were strictly controlled and matched for things like fiber, sugar, and fat content to make sure the researchers were measuring the effect of processing alone, not just the nutrients. Each participant followed one diet for two weeks, took a break, and then switched to the other diet for two weeks.

Why Are Ultra-Processed Foods Bad?

According to John Hopkins University, Ultra-Processed Foods (UPFs) contains ingredients you wouldn't find in a home kitchen. These include chemical-based preservatives, industrial emulsifiers (like certain oils), high-intensity sweeteners (like high-fructose corn syrup), and artificial colors and flavors.

Furthermore, UPFs undergo intense factory processing techniques like molding, extrusion, and chemical alteration. The final product often bears almost no resemblance to the original ingredients it came from.

Common examples of UPFs include soda, packaged snacks (chips, cookies), candy, boxed macaroni and cheese, frozen ready-to-eat meals, lunch meats, and hot dogs.

Why Are Younger Gen Zs Are Overeating?

After following each two-week diet, the participants were given a breakfast buffet and allowed to eat as much or as little as they wanted. The researchers noticed a key difference based on age:

Ages 18 to 21

This younger group consumed significantly more calories during the buffet, especially after eating the high-UPF diet for two weeks. They were also more likely to gorge themselves even when they weren't hungry.

Ages 22 to 25

This older group ate less and did not show the same tendency to overeat.

The study suggests that being a younger adult may be a risk factor for eating too many calories after being exposed to a high-UPF diet. This indicates that the younger participants may be more influenced by the strong, appealing nature of junk food.

How Much Health Risks Do UPFs Pose?

The lead researcher noted that even though this was a short-term trial, if this kind of increased calorie intake continues over time, it will almost certainly lead to weight gain in these young people.

The findings are especially concerning because UPFs have already been linked to 32 negative health issues, including higher risks of heart disease, cancer, Type 2 diabetes, and mental health problems. Experts predict that if drastic measures are not taken, a third of Americans aged 15 to 24 could meet the criteria for obesity by 2050.
