🚨5 Everyday Habits Destroying Your Gut

Dr Karan's Weekly Dose

A weekly newsletter to help you live a happier, healthier life!

I’ve never spoken about this before, but over the last few years I’ve mentored dozens of healthcare professionals (doctors, dentists, PAs etc) to help them grow their social media channels so we can get more experts online to combat misinformation.

An added bonus is they have their own brand presence and can get their own voice out there! (you may even recognise or follow some of them šŸ˜‰).

Anyway, I love educating and since so many professionals slide into my DMs asking me for advice about growing their presence online, I've decided to start doing it formally.

🚨5 Everyday Habits Destroying Your Gut...and how to fix them

​
If it’s true that we are what we habitually do, then the gut microbiome is not just what we regularly put into it, but also the sum total of all our other routines.

Here are 5 daily habits that might be putting your gut health at risk and what you can do about them.

1ļøāƒ£ Stop Scrolling On The Toilet

Yes, we’ve all done it. In fact….are you in the Oval Office right now?

The average bowel movement should take between 3-5 minutes, whereas spending upwards of 10 minutes in the ceramic cockpit increases pressure on the pelvic floor, raising the risk of haemorrhoids.

However, a 2025 study found that 37% of phone users spend more than 5 minutes on the toilet compared to just 7% of non-phone users (PMID 40901789).

So, here’s the first simple change - leave the phone away from the throne.

2ļøāƒ£ Always Eating The Same Stuff

Your gut microbes thrive on diversity and always eating the same stuff isn’t going to deliver.

Even if you do eat 30g of fiber per day, you might not be feeding the whole of the gut if what you eat doesn’t contain a selection of slow, medium and fast fermenting fibers…(p.s this is exactly why we formulated LOAM to have a mix of all 3 fiber types, which no other fiber supplement has!).

Aiming to eat 30 different plants (fruit, veg, nuts, seeds) per week is a good step in the direction of diversity.

3ļøāƒ£ Eating In A Rush

Digestion begins in the mouth, so rushing through it is counter productive. Eating quickly can result in bloating, overeating and poorer digestion due to less chewing.

Simple hack: place your cutlery down on the table between bites to spend more time chewing and less time shovelling.

4ļøāƒ£ Not Moving

The simplest way to improve digestion, reduce the risk of constipation and even move gut microbiome composition favourably is to move.

A 10-minute walk after a meal will reduce blood sugar spikes, improve digestion and snag you anywhere between 500-1000 extra steps.

5ļøāƒ£ Not Planning

Very few people get 30g of fiber by accident. This becomes even more difficult if you’re following a diet or fasting.

I'm certainly not telling you to not diet or fast; however, if you do, you might need to spend a little bit of time planning how to get enough fiber. It’s not sexy, fun or glamorous, but your gut microbiome will thank you for it.

One cheat code for those hard days or if you’re on a GLP-1 is using a fiber supplement like LOAM. A 10g serving of fiber that will dissolve into your morning coffee without trace. That means you leave for work safe in the knowledge you’re a third of the way to your daily fiber target.

šŸ‹ļøStopped Training? Read This

​
See if this sounds familiar:

You take up a new sport or fitness habit: going to the gym, working out at home, taking your creatine or fiber supplement every single day or taking a walk after lunch.

You clock up one or two months of regular practice: the streak on your wearable hits double, then triple figures.

People start to notice!

Then….something happens.

One of the kids gets ill, or you go on holiday or you just fancy a break and….

Next thing you know it’s been a month since you last so much as looked at a weight.

I know from experience how difficult it can be to get back on the wagon and how disheartening it is when you realise you can’t do what you were doing before.

However, a recent study (PMID: 39364857) suggests training breaks - planned or imposed - might be exactly what you need.

Half the participants - all of whom were untrained individuals - trained continuously for 20 weeks, while the other half trained for 10 weeks, then had a break for 10 weeks and then trained again for the final 10 weeks.

At the end of the study, which group do you think had made the most gains in muscle size and strength?

That’s right, there was no significant difference between the two groups!

That doesn’t mean the group that had a break didn’t lose any of their gains - they did.

The point is, when they recommenced training they were able to make up their lost ground quicker than the continuous group in the equivalent time. Everyone ended up in the same place.

So, here’s what to do with this information:-

1ļøāƒ£ When an unexpected training break rears its head (having a baby wasn’t unexpected, but my training definitely took a hit) don’t panic. Get back to it as soon as practical and hopefully you’ll see the benefits.

2ļøāƒ£I’m no personal trainer, but all the fitness influencers out there recommend a ā€œde-loadā€ week every couple of months. This research suggests a week of lower or even zero training is unlikely to have any permanent effects, so don't be afraid of occasionally taking a break.
3ļøāƒ£ When you start up again, it’ll be about reestablishing habits, not picking up where you left off. Accept you might only be able to do less, but remember you’ll return to your best more quickly.


REFLECTIONS

šŸ“–Lessons From The Odyssey

One of the most famous stories from the Odyssey is of Odysseus outsmarting the Sirens.

No one could resist the alluring calls of these mythical beings with many ships wrecked as a result.

However, by filling his sailors’ ears with beeswax and tying himself to his ship’s mast, Odysseus resisted temptation.

He was wise enough to know in advance that he wouldn't be able to resist the Sirens’ call, so he took action in the present to prevent himself from falling into temptation.

Psychologists call this a commitment device, placing constraints on yourself in the present to prevent poor choices in the future.

Commitment devices work in almost every context imaginable. For example:

  • Setting up automatic savings rather than waiting to see how much money you have left at the end of the month
  • Giving a friend $100 and telling them to donate it to charity if you don’t complete X
  • Not keeping junk food in the house

Psychologists believe they work because they are a form of strategic self-control (ā€œI will remove the opportunity for temptation to ariseā€) rather than effortful self-control (ā€œI’ll resist temptation when it arisesā€).

So the next time you decide to take up some difficult new habit, think about what commitment device you can make use of to make it that little bit easier.

šŸ¤– My Digital Librarian

Just because you don't need glasses doesn't mean you can't improve your eyesight. And how can we reduce the impact of excessive screen time on our eyes? These are just two of the topics that came up in my conversation with Dr Bryce Appelbaum. Of course, if you're pushed for time you could always ask my digital twin

šŸ“ WHAT I'M DOING THIS WEEK

😁 Optimising My Flossing Routine

I've switched my normal floss, which is this cheese grater-like piece of string for a thicker piece of "rope" which should go easier on my gums. If you don't floss - start. If you do floss, explore the different options and always look after your gums.

​
🄱 Adios to Oura...For Now

Only a glutton for punishment would pay for an Oura subscription while looking after a new baby. I decided to cancel mine this week because, when a good night's sleep is such a distant memory...what's the point? Maybe I'll go back to it in the future, but for now I'm taking Magnesium Bisglycinate and that's it.

🌿Using More Herbs

Evidence shows adding herbs to your cooking helps to shape microbial diversity in the gut (PMID 34050197). They certainly count to your 30 plants per week target, so whenever I cook anything, even just a 2-egg omelette, I'm trying to add some extra seasoning. Small, but mighty.

P.S It might surprise you to know that I'm not much of a doom-scroller online and don't actually watch many videos on social media...I get a lot of my info from other newsletters! I'm a long term subscriber to this one that gives me fact-checked, unbiased news across politics, science, tech, and more!
