You may have seen the term “fibremaxxing” floating around online. Everyone’s talking about it. It’s the latest wellness and nutrition trend taking off on social media – especially TikTok.

While it’s not a scientific term, fibremaxxing has gained serious traction alongside the rise of weight loss content. TikTok creators like Pamela Corral have helped push it into the spotlight. One of her fibre-rich meal videos reached over 10 million views.

Here, we explain the benefits and cautions of fibremaxxing – and whether you should be eating more fibre on GLP-1 weight care medication.

What is Fibremaxxing?

Fibremaxxing refers to a social media trend that encourages people to eat more high-fibre foods. Essentially, it’s about maximising your fibre intake to support digestion, fullness and overall health.

Why is Fibre So Important?

Fibre is a type of carbohydrate your body can’t digest. It has multiple health benefits and plays a vital role in:

  • Supporting healthy digestion and regular bowel movements
  • Helping you feel fuller for longer, which may reduce overeating
  • Managing blood sugar levels and cholesterol, reducing the risk of heart disease

Fibre-rich foods include:

  • Vegetables
  • Fruits (especially with the skin on)
  • Beans
  • Lentils
  • Oats
  • Seeds
  • Wholegrains 

Is Fibremaxxing Healthy?

The spotlight that was once firmly on high-protein products for weight loss is shifting toward gut health. And honestly, that’s not a bad thing.

A lot of the so-called “high-protein” snacks and meals promoted were ultra-processed and packed with additives. This was – and still is – overlooked by many of us because the focus was so heavily on the protein content. There was little attention paid to the overall quality of the food.

So the growing awareness around the benefits of dietary fibre is refreshing. And yes, fibre has real benefits for digestion, fullness and weight management. It’s also good for heart health and helps the growth of good gut bacteria.

The government says we should be eating 30g of fibre a day. But most adults are only eating about 20g a day, on average. In Scotland, only 6% of people meet the recommended daily fibre intake. This means 94% are falling short! So, the conversation around fibre isn’t just trendy – it’s timely, and long overdue.

That said, like many health trends, fibremaxxing needs to be approached with care. You shouldn’t be eating extreme amounts or following viral hacks without context. But while it’s important to be cautious, this trend is also shining a light on a much bigger issue we can’t ignore.

Should I Be Eating More Fibre on GLP-1 Weight Medication?

A high-fibre diet can support your body while you’re on GLP-1 medications like Mounjaro, Saxenda or Wegovy. These medications slow digestion, which helps reduce appetite. But that can also lead to side effects like constipation, bloating, or nausea.

Some people even feel anxious about eating as their hunger cues change. That’s where fibre comes in: it can be part of a gentle, structured way to reintroduce balanced meals and support better food tolerance. This can help you manage these common stomach-related side effects.

But while fibre has many benefits, it’s important not to overdo it too quickly. Jumping from low fibre to high fibre overnight can cause exactly the digestive issues you’re trying to fix. Your gut needs time to adjust to the new amount and types of fibre.

While fibremaxxing can be beneficial over time, it’s not about hitting a magic number with powders, pills, or gummies. A varied, food-first approach is key. So is staying well hydrated.

Post-GLP-1s: Using Fibre for Long-Term Maintenance

Some people may experience weight regain – or hit a plateau – after their GLP-1 journey. That’s why it’s important to start thinking about long-term habits before stopping the medication.

One of the most useful tools you can build into your routine is fibre.

Start to gradually increase fibre during your journey (not just after). This can help lay the groundwork for post-medication maintenance. Fibre-rich meals help keep you full for longer, support digestion, and can make your eating patterns feel more stable – especially once appetite returns.

Building a realistic, sustainable way to include fibre daily – not through extremes, but through balanced meals – can help support weight management long-term. It’s not about short-term hacks. It’s about creating meals that leave you feeling satisfied and nourished.

You can use nutrition labels to check how much fibre is in packaged foods. Or check this NHS guide for examples of meals and their fibre content.

Key Takeaways

  • Fibremaxxing is a Growing Social Trend: It’s raising awareness of fibre’s benefits but should be approached with balance, not extremes.
  • Fibre Can Support GLP-1 Users: It may help manage side effects like constipation or nausea. And it can ease anxiety around eating.
  • Start Slow and Let Your Gut Adapt: A sudden fibre increase can cause discomfort; gradually building intake is key.
  • Fibre Plays a Role After GLP-1s Too: It supports satiety, stable eating habits, and long-term weight maintenance.
  • Focus on Whole Foods Over Supplements: Fibre powders and gummies aren’t magic. Variety from real food matters most.
