As a result, we\u2019re missing out on the roughage we need to keep our gut microbes happy, our immune systems powerful, our poops soft, our hearts healthy \u2013 and so much more.<\/p>\n<p>But trying nobly to add fibre to every single meal \u2013 in the form of fruit, veggies, wholegrains, legumes and pulses \u2013 can feel overwhelming, especially if you\u2019re used to low-fibre eating.<\/p>\n<p>If you\u2019re looking to up your fibre intake, the best place to start is breakfast. It\u2019s called \u2018the most important meal of the day\u2019 for a reason \u2013 what we eat in the morning can help set us up for the day ahead.<\/p>\n<p>But starting your day with a fibre-packed brekkie not only makes it easier to manage your fibre intake; it can also make the fibre you do eat more effective. Here\u2019s why.<\/p>\n<p>Setting you up for the day<\/p>\n<p>Studies have found that choices we make at breakfast can influence what we eat for lunch, dinner and snacks.<\/p>\n<p>In fact, an <a href=\"https:\/\/www.mdpi.com\/2072-6643\/11\/1\/175\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Australian study<\/a> found that adults who ate a high-fibre breakfast were likely to eat healthier, higher-fibre foods for the rest of the day, compared to those who skipped breakfast or chose lower-fibre options.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/fibre-timing-breakfast.jpg\" alt=\"Photo of a smiling man eating breakfast from a bowl in their kitchen\" class=\"wp-image-215237\"\/>A good breakfast lays the foundation for a great day &#8211; Image credit: Getty Images<\/p>\n<p>\u201cIf you\u2019re having a balanced breakfast, it\u2019s likely to make healthy eating easier later on too,\u201d says <a href=\"https:\/\/www.kcl.ac.uk\/people\/emily-leeming\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dr Emily Leeming<\/a>, a nutrition scientist at King\u2019s College London. \u201cIt\u2019s like how, intuitively, we think breakfast will help set you up for the rest of the day.\u201d<\/p>\n<p>Fibre is unlike most other nutrients \u2013 such as carbohydrates, proteins and fats \u2013 because we don\u2019t directly digest it. Instead, it travels through the gut and feeds the microbes living in the colon.<\/p>\n<p>And on its journey through the digestive system, fibre helps us feel full. It adds bulk to our food, slows down how it travels through the stomach, helps stretch the stomach muscles, and therefore sends more fullness signals to the <a href=\"https:\/\/www.sciencefocus.com\/the-human-body\/human-brain\" rel=\"nofollow noopener\" target=\"_blank\">brain<\/a>.<\/p>\n<p>The nutrient affects how we extract energy from food too. When carbs are combined with fibre, their sugars enter our bloodstream more gradually, keeping our blood sugar and energy levels more stable.<\/p>\n<p>That, in turn, affects our appetite. <a href=\"https:\/\/www.nature.com\/articles\/s42255-021-00383-x\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">In 2021<\/a>, scientists discovered that people whose breakfasts have a milder effect on their blood sugar \u2013 in part, due to fibre \u2013 usually go on to feel less hungry, and consume fewer calories, for the rest of the day.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/fibre-timing-gut.jpg\" alt=\"Natural products for healthy bowel.

Don\u2019t worry \u2013 that\u2019s not where the positives end. Breakfast fibre can also help you do a perfect morning poop.<\/p>\n<p>That\u2019s true no matter when you eat it.<\/p>\n<p>Harvard gastroenterologist <a href=\"https:\/\/www.trishapasricha.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dr Trisha Pasricha<\/a>, author of You\u2019ve Been Pooping All Wrong, says: \u201cOne of the most predictable ways to improve your poop is simply to eat more fibre. When you see that softer, more effortless poop, and you\u2019re not straining, that tells me that you\u2019re meeting your fibre goals.\u201d<\/p>\n<p>But fibre is especially effective in the morning, because it supports the natural circadian rhythm of your gut.<\/p>\n<p>According to Pasricha, your colon is dormant while you <a href=\"https:\/\/www.sciencefocus.com\/the-human-body\/sleep\" rel=\"nofollow noopener\" target=\"_blank\">sleep<\/a>. \u201cThen when you wake up, you get cues from your environment \u2013 and [your colon] wakes up,\u201d she says. \u201cIt buzzes with activity most strongly for the first one or two hours on waking.\u201d<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/fibre-timing-poop.jpg\" alt=\"Person sitting on toilet and holding a toilet paper roll\" class=\"wp-image-215238\"\/>When you wake up, so does your gut &#8211; Image credit: Getty Images<\/p>\n<p>That activity includes subtle contractions that push your poop towards its exit. A healthy, fibre-full breakfast can help stimulate that internal voyage, so you have a satisfying poop without straining.<\/p>\n<p>\u201cYou can make or break your day depending on whether you\u2019ve had a good bowel movement in the morning,\u201d says Pasricha. \u201cI fully believe that.\u201d<\/p>\n<p>Research agrees. When 153 adults started eating a high-fibre wheat-bran breakfast in the morning, they <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23609776\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">reported<\/a> much better gut health after just two weeks.<\/p>\n<p>Participants said that they could poop more easily, and that they felt less bloated, less sluggish, happier and more energetic \u2013 thanks to just 5.4g of extra morning fibre.<\/p>\n<p>Meeting your fibre goals<\/p>\n<p>Switching to a higher-fibre breakfast isn\u2019t just extra powerful, it\u2019s also relatively easy.<\/p>\n<p>Unlike lunch or dinner, many of us eat the same breakfast every morning, so making a simple swap here could cumulatively have a significant impact on your overall diet.<\/p>\n<p>Leeming says: \u201cBreakfast is a key opportunity to add in fibre. If you\u2019re skipping breakfast, it\u2019s going to be much harder for you to get the fibre you need.&#8221;<\/p>\n<p>That\u2019s not to say that brekkie should be our only focus. The average adult \u2013 in both the <a href=\"https:\/\/www.gov.uk\/government\/statistics\/national-diet-and-nutrition-survey-2019-to-2023\/national-diet-and-nutrition-survey-2019-to-2023-report\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">UK<\/a> and <a href=\"https:\/\/www.dietaryguidelines.gov\/sites\/default\/files\/2020-12\/Dietary_Guidelines_for_Americans_2020-2025.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">US<\/a> \u2013 is eating just over half the recommended amount of 30g (1oz) of fibre per day.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/fibre-timing-breakfast-spread.jpg\" alt=\"healthy breakfast with granola, pancakes, fresh fruits and coffee cup, top view\" class=\"wp-image-215239\"\/>Many of your breakfast favourites \u2013 like fruit, oats and wholemeal toast \u2013 are already packed with fibre &#8211; Image credit: Getty Images<\/p>\n<p>In such dire circumstances, breakfast alone is unlikely to cut it. Leeming adds that suddenly introducing a lot of fibre to breakfast \u2013 while continuing to eat very little at lunch or dinner \u2013 may not do our digestion any favours either.<\/p>\n<p>\u201cThe best thing is to eat fibre across the day, because it can take time for your gut to adapt to fibre,\u201d she says. \u201cIt\u2019s a little bit like rocket fuel for your <a href=\"https:\/\/www.sciencefocus.com\/the-human-body\/how-to-boost-your-microbiome\" rel=\"nofollow noopener\" target=\"_blank\">gut microbiome<\/a>. You\u2019re less likely to have uncomfortable symptoms if you\u2019re spreading it across the day.\u201d<\/p>\n<p>Low and slow \u2013 that\u2019s the best way to incorporate more fibre into your diet, explains Leeming, to avoid bloating and tummy aches. However, it\u2019s also true that every little helps.<\/p>\n<p>\u201cEven small amounts of fibre \u2013 just seven grams more per day \u2013 is related to significantly lower risk of <a href=\"https:\/\/www.sciencefocus.com\/the-human-body\/the-discoveries-bringing-an-end-to-heart-attacks\/\" rel=\"nofollow noopener\" target=\"_blank\">heart disease<\/a>, bowel cancer and type 2 diabetes,\u201d she says.<\/p>\n<p>And you may find it easier to concentrate on morning upgrades first, since so many breakfast foods are naturally fibre-rich.<\/p>\n<p>For instance, the cereal aisle is lined with wholegrain options, so you could easily switch your cornflakes for something like shredded wheat.<\/p>\n<p>Alternatively, swap your white toast for seeded rye bread. Or try porridge, overnight oats, Greek yoghurt or kefir with a generous helping of high-fibre toppings, such as nut butter, seeds and berries.<\/p>\n<p>If you eat it every day, this simple breakfast swap could make a major difference to your overall health.<\/p>\n<p>Read more:<\/p>\n","protected":false},"excerpt":{"rendered":"Unless you\u2019re a lentil-loving veggie-phile who prefers bean burgers over beef, the chances are, your body is crying&hellip;\n","protected":false},"author":2,"featured_media":480995,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[163,85,46,543],"class_list":["post-480994","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-health","tag-il","tag-israel","tag-nutrition"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/480994","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=480994"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/480994\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/480995"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=480994"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=480994"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=480994"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
