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.

Could there be a diet that allows you to eat more and still helps you lose weight? For the longest doctors and health experts praised the Mediterranean diet. This is because it is heart-friendly, and has a mix of fruits, whole grains, vegetables, and sea food. However, new research suggests that even a simpler diet would work better. As per British scientists, by simply cutting out ultra-processed foods, and sticking to unprocessed whole foods could lead to greater calorie reduction and weight loss.

Eating More, And Still Losing Weight? What Is Working

The key is to reduce the intake of calories, which is possible when you cut your ultra-processed foods. In a study, researchers found that people who followed a completely unprocessed diet consumed around 330 fewer calories per day than those who ate more processed food.

What surprised scientists was that participants actually ate more food by volume. Those on the whole-food diet consumed about 57 percent more food overall, yet still ended up eating fewer calories. The reason lies in the type of foods they chose, such as fruits, vegetables, salads, and lean proteins, which are naturally lower in calorie density.

This means people could eat larger portions, feel full, and still reduce their total energy intake.

Why Are Ultra-Processed Foods Problem?

Ultra-processed foods, often called UPFs, include items like ready meals, packaged snacks, sugary cereals, sweets, and hot dogs. These foods are typically high in calories, sugar, unhealthy fats, and additives, while being low in fiber and nutrients.

Ultra-processed foods, engineered with additives, preservatives, and artificial ingredients, now comprise over half the average American diet, based on data from the U.S. Department of Agriculture. Their ubiquity and intensive marketing have made them seem inevitable, but accumulating evidence indicates that the health toll is much more serious than realized.

Under the NOVA food classification system, UPFs are defined by their intensive industrial processing, which is typically used to produce hyper-palatable and highly profitable foods. Yet, the convenience comes with an increasingly large body of evidence showing that these foods contribute to a variety of chronic diseases, including cardiovascular disease, obesity, diabetes, depression, and various forms of cancer.

Researchers say UPFs may quietly push people towards overeating without realizing it. Even small portions can contain a large number of calories, making weight gain more likely over time.

The study suggests that when people are given the option to eat foods in their natural or minimally processed form, they tend to make smarter choices on their own.

How Was The Study Conducted?

The research followed 20 overweight adults, including 10 men and 10 women, with an average age of 31. Participants were divided into two groups.

One group followed a two-week diet based on minimally processed foods such as vegetables, fruits, salads, and lean meats. The other group ate a diet rich in ultra-processed foods like hot dogs and ready meals. After two weeks, the groups switched diets.

Importantly, the meals were matched for nutrients such as fat, protein, carbohydrates, salt, and fiber. Despite this, those eating whole foods consumed fewer calories and lost nearly one kilogram in weight.

Feeling Fuller and Reducing Cravings

Researchers believe fruits and vegetables played a key role. These foods are high in water and fibre, which lowers their energy density. As a result, people can eat more without consuming too many calories.

Experts also point out that natural fiber helps people feel full for longer and supports gut health. Fibre can trigger hormones that regulate appetite, reducing cravings and helping with long-term weight control.

What This Means for Everyday Diets

The findings add to growing evidence linking ultra-processed foods to a range of health problems. Studies have previously associated high UPF intake with dozens of illnesses.

In the UK, ultra-processed foods make up about 57 percent of the average diet, one of the highest levels in Europe. Experts recommend that around 80 percent of daily food intake should come from whole or minimally processed foods.

The message from scientists is simple. You do not need complicated diet rules. Choosing foods closer to their natural form may help you eat better, feel fuller, and lose weight more sustainably.

A small study suggests that people who avoid ultra-processed foods (UPFs) consume around 330 fewer calories each day on average—even while eating more by weight. Researchers say that when food is offered in its natural, unprocessed form, people tend to make “much smarter decisions.”

The study, conducted by the University of Bristol, reanalysed data from a U.S. clinical trial with 20 participants, which had found that eating only UPFs leads to overeating and weight gain. The team discovered that people eating solely whole foods naturally chose fruits and vegetables over higher-calorie items like pasta and creamy dishes.

Ultra Processed Foods: What Are They?

Ultra-processed foods are ready-to-eat products made in factories using industrial methods. They rely on chemically modified ingredients and additives rather than whole foods, and often contain little to no real nutrition. Instead, they are loaded with sugar, saturated fats, and salt, which can contribute to chronic health problems over time.

Ultra Processed Foods: How Whole Foods Change Eating Habits

According to the study, as per The Independent, people avoiding UPFs ate 57% more food by weight. Jeff Brunstrom, professor of experimental psychology at the University of Bristol, explained: “It’s exciting to see that when people are offered unprocessed options, they instinctively select foods that balance taste, nutrition, and satiety while still reducing overall calorie intake. Our dietary choices aren’t random—when food is in its natural state, people actually make smarter decisions than we expected.”

Ultra Processed Foods: Common Examples

According to NOVA, ultra-processed foods are ready-to-eat or ready-to-heat products made mostly from industrial ingredients and additives, rather than whole foods. Common examples include:

• Chips
• Carbonated drinks
• Instant noodles
• Ice cream
• Chocolate
• Biscuits
• Sauces and instant sauces
• Ready-made meals
• Mass-produced packaged bread
• Sausages and hot dogs
• Burgers
• Chicken and fish nuggets
• Instant soup
• Meal replacement shakes and powders
• Candy
• Pastries
• Fruit yoghurt
• Fruit drinks
• Cake mix
• Margarine
• Sweet or savory packaged snacks
• Energy bars

These foods are often high in sugar, salt, and unhealthy fats, and low in natural nutrients.

Ultra Processed Foods: Vitamin Fortification Can Mislead

The research also highlighted a concern: some UPFs meet micronutrient requirements through fortification. For example, pancakes and French toast sticks contained vitamin A. However, participants consuming only whole foods got their vitamin A from carrots and spinach, which are far lower in calories.

Ultra Processed Foods: The Calorie-Micronutrient Trade-Off

Dr. Annika Flynn, senior research associate at the University of Bristol, said: “This suggests that UPFs can deliver both calories and nutrients in a single product, which may lead to overconsumption. Whole foods, on the other hand, maintain a healthy balance, encouraging people to favour nutrient-dense options like fruits and vegetables instead of high-calorie foods such as pasta and meat.”

Ultra Processed Foods: Why This Matters for Everyday Eating

The findings underline how simple changes—choosing minimally processed, whole foods—can naturally reduce calorie intake without feeling restrictive. By letting people eat more volume while cutting energy intake, whole foods may help manage weight and improve overall nutrition.

Health specialists have cautioned that a widely used dairy milk alternative may come with downsides many people are unaware of, especially when consumed first thing in the morning, according to Mirror. Oat milk, a popular plant-based and dairy-free option, is often praised for its fibre content and for being fortified with calcium and vitamin D, both important for bone health. However, dietitians point out that compared to other plant-based milks such as almond milk, oat milk tends to contain higher amounts of carbohydrates, added sugars and oils.

What Is Oat Milk Made Out Of?

Oat milk is a dairy-free, plant-based drink that is commonly valued for its fibre content and added calcium and vitamin D, which support bone strength. That said, health experts note that it generally contains more carbohydrates, sugars and oils than many other plant milks, including almond milk.

Registered nutritionist Jenna Hope explains that oat milk is usually produced by creating a syrup from oats, which is then mixed with water. She adds that many well-known oat milk brands also include added oils, emulsifiers and stabilisers to improve texture and shelf life.

Why Is Oat Milk Bad For Your Health?

Experts say certain aspects of oat milk may negatively affect health, particularly when consumed on its own. Speaking to Parade, registered dietitian Melissa Rifkin said that while oat milk lattes can fit into a healthy diet, they are not nutritionally complete by themselves. She noted that although oat milk offers some fibre, most oat milk lattes are low in protein and fat, two nutrients that help regulate blood sugar levels and promote fullness.

Sharing a similar view, registered dietitian Nour Zibdeh told The Independent that oat milk’s high carbohydrate content can lead to sharp rises in blood sugar when consumed in the morning. This effect is less pronounced with dairy milk, which naturally contains protein and fat that help balance its sugar content.

Ms Zibdeh also told Parade that oat milk is low in protein and fat, which contributes to greater blood sugar spikes. French biochemist and author Jessie Inchauspé, widely known as the “Glucose Goddess”, has also criticised oat milk. In a 2024 interview with American entrepreneur Marie Forleo, she described oat milk as similar to drinking “starch juice”, explaining that oats are a grain and grains are primarily made up of starch.

Should You Replace Oat Milk With Cow Milk?

Overall, nutrition experts tend to agree that cow’s milk offers greater nutritional value. Regular dairy milk intake has been linked to better metabolic and heart health, and cow’s milk contains higher levels of key micronutrients such as phosphorus, which supports healthy bones and teeth, along with calcium, vitamin D, B vitamins and potassium, compared to oat milk.

That said, cow’s milk is not suitable for everyone. Allergies, taste preferences and vegan diets mean many people rely on plant-based alternatives. If oat milk is your preference, there is no need to panic. Experts stress that moderation is key and that oat milk can still be enjoyed as part of a balanced diet.

Choosing oat milk does not mean it needs to be completely removed from your routine. There are simple ways to enjoy it while being mindful of expert advice. For those who love an oat milk latte, pairing it with protein-rich foods such as eggs or Greek yoghurt can help balance blood sugar levels and make the meal more satisfying.
