🥱 Stop Trying So Hard To Sleep

Dr Karan's Weekly Dose

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

If you live in the UK, I want to hold my hands up and take the blame for something before we get into this week's newsletter.

​LOAM is finally properly available in the UK!

You might be one of the 20,000 people who joined the UK waitlist for LOAM in 2025, then messaged me to ask, quite reasonably, why a British founder had somehow made his product easier to buy in America than at home.

If so, thank you for your patience and I'm sorry it took so long.

The last eight months have involved an unreasonable amount of warehouse, logistics, regulations, freight, spreadsheets and late-night emails.

All while I've been trying to grow my start-up baby and keep my actual baby alive.

I am very tired.

But also very happy.

Because the UK is home. I grew up here, trained here, worked as a doctor here and this is where the original LOAM experiment started with far too many bags of fiber scattered around my kitchen.

And for those of you in the EU, I havent forgotten you either.

Proper EU availability is something I'm working on although it's going to take a little longer - sorry. In the meantime, having UK fulfilment should hopefully mean cheaper and easier shipping for some European customers too.

Thank you for sticking with me.

Gut health

🍫Eat Chocolate For Elite Gut Health

Yes, you read that title correctly and no, I'm not entirely cooked (Gen Z slang, apparently).

I often write about “eating for gut health” and you don't need to be a long-time reader to know the basics - legumes, fruit and veg, whole grains, nuts and seeds and, whatever you do, limit your consumption of those sweet treats like chocolate, jam and popcorn because, I mean, come on that’s obvious, right?

Wrong

Chocolate, jam and popcorn might sound like a six-year-old’s birthday party menu, but can also be a regular part of a proper, grownup, fibermaxxing adult’s diet too

Don't believe me?

Chocolate

OK, the only caveat I need to make here is it needs to be dark chocolate, minimum 70% cocoa solids.

Just 30g will give you 3.5g of fiber as well as 45% of your daily iron, and 60% of your daily copper

I love it stirred into overnight oats accompanied by frozen berries. Depending on the quantity of oats you eat, breakfast can easily top double digits of fiber meaning the day is already won.

Jam

The key here is to make your own jam (jelly for the American readers, I've made that mistake before!) with chia seeds or LOAM. 3 tablespoons (25-30g) of chia mixed with 150g of frozen berries (mushed into a runny paste) and a squeeze of lemon/lime makes a fiber-charged fruit jam after 10 minutes in the fridge. The whole thing is 20g+ of fiber so best not eat it all in one go! Spread it on some wholegrain toast for another fibertastic breakfast

Popcorn

Just 25g of popcorn contains 3-4g of fiber (who only eats 25g of popcorn?!) so this can be a snack of champions if you’re fiber-maxxing. The key is just not to cover it in sugar, salt or butter like you get at the movies. Of course you could also stir it through some melted dark chocolate for maximum smug points.

One thing about these three fibre heroes is that they all ferment relatively slowly, meaning they reach the later stages of the colon before being fermented by gut bacteria. To feed the microbiome at the start of the colon, you'll need to consume fast-fermenting fiber too.

Or you could just use LOAM: a fiber supplement that covers the whole fermentation spectrum giving your gut microbiome different fibers to work with throughout the entire colon. One sachet is 10g of fiber that you can add to your coffee or overnight oats and you won't even notice.


GENERAL health

🥱 Why You DON'T Need Perfect Sleep

Right now, you’re probably thinking I’ve lost the plot. First telling you to eat chocolate and now saying not to worry about your sleep!

I’ve not gone bonkers, hear me out first!

There's an interesting paradox about many people living in preindustrial societies. They tend to sleep less than you and me, wake up more often…yet, when you ask them "Do you ever have trouble sleeping?” they don’t even understand the question.

How can they have “objectively” worse sleep than us, but not recognise it?

First, let's see what we can learn from the groups of people who are thought to most resemble our ancient hunter-gatherer ancestors.

Light

You probably know the advice is to get exposure to natural light as soon as possible after you wake up. It’s true that light helps regulate the circadian rhythm, our body’s clock telling us when to sleep and wake. For those of us waking up in the dark during winter months and spending all day in an office, the best advice is to accumulate exposure to light throughout the day. Go for a walk in your lunch break or work next to a window if you can.

​
​Temperature

Temperature is as much of a circadian regulator as light. Interestingly, the Hadza people of Tanzania’s sleep tends to track temperature rather than light (e.g. they wake up before dawn). In contrast, most of us live in homes where the temperature is the same all the time. Try turning down the thermostat or opening a bedroom window before you go to sleep.

​
​Nighttime activity

Researchers studying the Hadza report these people engage in “radically different” activities in the final hours before bed compared to during the day. This is thought to be another signal to our brain and body that it's time to sleep. So make it a habit to avoid working at night if you can...

..and those “radically different” activities tend to be communal rather than individual. Even for people who live alone, taking part in some kind of group class, having friends over for dinner or just calling a friend might improve sleep.

In our first clinical trial for LOAM we noticed many participants who took a double dose reported reductions in levels of perceived stress and a number of customers have told us about improvements in fatigue and energy.

All anecdotal of course, but we wonder if this is a result of the gut-brain axis in action. We're in the early days of planning a trial looking at LOAM and the gut-brain axis, so if you're a researcher in that area, please get in touch.

Finally, remember how I said many of these modern hunter-gatherers don't recognize the concept of a poor night’s sleep?

Maybe there’s a lesson for us to learn there too.

What if your sleep improved if you just stopped worrying about it so much? Maybe it doesn't matter if you don't get 8 hours of uninterrupted sleep (after nearly 5 months of parenthood, I can’t remember what that even feels like!) Perhaps it’s ok to wake up feeling a bit groggier some days than others?

Being ok with less-than-perfect sleep might be the ultimate hack there is.


REFLECTIONS

🍀 How To Become More Lucky

If you’ve ever thought, “some people just have all the luck” and that person is never you…

…you might be right.

But there are ways to make yourself more lucky, that is to say, things you can do that make it statistically more likely that good things will happen to you, which is the best definition of luck I can come up with.

Try some of these:

1️⃣ Always ask for what you want

The absolute worst outcome here is the answer is “no”, in which case you’re in exactly the same situation as you started in. Alternatively, the answer might be “not yet” in which case you can get an idea of what you need to do in order to get what you want. Great! And, of course, there’s always the chance the answer will be, “yes”.

2️⃣ Start Publishing Content Online

I can trace almost every good thing that’s happened to me in my professional life over the last few years to my decision to start posting content online in 2020. You don’t have to start making YouTube videos, it could be as simple as starting/updating your LinkedIn. Again, the worst outcome is you develop some skills related to posting content and improve your consistency. None too shabby. The potential upside is essentially infinite.

3️⃣ Find or become a mentor

Everything you want to do has been done by someone else before. They have valuable experience and more often than not, they’ll want to share it with you. This could be in-person or online. After all, there are experts of all shapes and sizes posting content you can access for free. Alternatively, what valuable experience could you share with someone else?

4️⃣ Have more conversation with strangers

This time, I really do mean just in real life. The person working in the shop, the commuter you always see in the morning, dare I say it…your next door neighbour? It all starts with “good morning, how are you” and who knows where it will go from there?

5️⃣ Take on a leadership role in your community

That could be at work, in church, at your kids’ school or your online community of choice. It will almost certainly expose you to novel situations, in which you'll have to come up with solutions to problems you’ve never encountered before.

If you feel strongly about some health things or just want to say hi? Hit reply... I’d love to hear it and hear from you! (yes I read every reply!!!)

🤩 WEEKLY HIGHLIGHTS

💉Big Pharma Cannot Be Stopped

Big Pharma is the institutional boogie man of our time. Influencers, politicians and many ordinary people are deeply distrustful of Big Pharma…and rightly so. But I’m convinced the Big Pharma narrative is more nuanced than that. This video is the result of my investigation.

💣 The Dangerous Invisible Fat You're Not Paying Attention To

Even slim people can have too much visceral fat (fat stored around the organs) and in this podcast Professor Jimmy Bell and I discuss what it actually does in the body, and why you shouldn't worry about your weight. You can listen to the full conversation on Apple Podcasts and I'd love it if you could leave a review and subscribe so you never miss an episode. Don't forget you can ask my digital twin any question you like related to any of my content.

🥩 The Rise of The Carnivore Diet Cult

You do know plants are out to get you, don't you?! And a whole stick of butter is just an hors d'oeuvres for some carnivores. Although I wrote about this video last week, I'm sharing it again just ICYMI. The comments section is worth a look if nothing else!

📝 WHAT I'M DOING THIS WEEK

🛄 Travelling as You Read This

Here are my travel non-negotiables of gut health 1) Eye mask on the flight to minimise sleep disruption 2) LOAM travel packs as nothing kills mood when you're on the road like gut disruption 3) Walking as much as I can in the light as soon as I land 4) Black coffee for breakfast to stimulate the gastrocolic reflex and keep my circadian gut timing on track.

​
​ 👶 Deep-diving Into The Baby Microbiome (again)

The little gremlin is nearly 5 months old and we aren't far off starting the solids journey! That being the case, I'm getting ready to jump back into the science but, in the meantime, any tips are more than welcome!

🗓️ Podcast Is Fully Booked!

For the first time ever, the podcast is fully booked up til the end of the year! I wrote last week about how I'm trying to lean more into long-form content like this newsletter, longer YouTube deep dives and podcasting. It's a lot of work, but I absolutely love it. I don't usually ask this, but in the spirit of this week's personal reflection, if you don't ask, you don't get! If you enjoy this newsletter, there's a high probability you'll enjoy the podcast too. Why not start with this exploration of the Male Fertility Crisis with Professor Sheryl Homa and if you enjoy it, leave a review and follow.

P.S I love learning about health and science but I want to broaden my knowledge to other things which interest (or scare) me like tech, politics and general world news...I feel like I've been submerging myself in a wellness bubble these last few years! I love reading this newsletter that gives me fact-checked, bite-sized and unbiased news to keep my dinner party conversations interesting!
