The Men’s Wellness Trends That Work (and the Ones That Don’t)

Somewhere between the end of COVID and the dawn of whatever this era is — call it the Age of Anxious Optimisation — we decided that normal, functional human biology was no longer good enough to give us a long life.

Suddenly, sleeping wasn't enough; you needed to track your HRV, stack your supplements, and cold-shock your nervous system into submission before 7am. Eating wasn't enough; it had to be time-restricted, carnivore-adjacent, or, God help us, involve raw organ meat sourced from a regenerative farm.

We get it. Men's health, for decades criminally under-discussed, is finally having its moment — and some of the new thinking is genuinely good. But the wellness industrial complex, now worth over $6 trillion globally, has a financial incentive to keep you anxious and spending. Not everything with a clinical-sounding name and a podcast sponsorship will make you healthier. Some of it will make you very, very unwell.

So, after hours of research and going down very disturbing rabbit holes, here is what's actually worth your time, and what you should leave firmly on the biohacker's shelf.

Do: The Cold Plunge

Yes, it's all over your Instagram. Yes, that shirtless tech founder you follow dunks himself in a tank at 5am and credits it with his mental clarity, his cortisol levels, and his eight-figure exit. And yes, the cold plunge has officially jumped the shark culturally — it is, at this point, the Man Bun of wellness. None of that changes the fact that the science is, quietly and somewhat annoyingly, stacking up.

Recently, a comprehensive 2025 systematic review and meta-analysis published in PLOS ONE, analysing 3,177 participants across 11 randomised trials, found meaningful improvements in mood, energy levels, and stress following cold-water immersion. A separate study published in Advanced Biology, found that just seven days of cold-water immersion triggered measurable cellular changes in young men. In plain English: your cells are getting a hard reset.

The neurochemical argument is equally hard to dismiss. Cold immersion produces a 530% surge in noradrenaline and a 250% spike in dopamine. That is the neurochemical equivalent of a very good morning. It also explains why people who do this regularly become insufferably evangelical about it at dinner parties.

So, yes, in short, without getting too technical. It is good for you. But the caveats are equally real: if you do a cold water plunge right after resistance training, it can actually be bad for you. The rule of thumb is to wait for at least six hours post-weights to freeze yourself to (almost) death. And if you have a history of heart conditions or arrhythmias, then don’t do it.

Eleven minutes per week, split across two to four sessions, is the dose Stanford's Andrew Huberman identifies as sufficient to produce the goods. You don't need a $20,000 tank. Your bathtub and a bag of ice will do. We know, we know — not very photogenic. Suffer through it.

Do: Intermittent Fasting

The diet world is a graveyard of things that worked brilliantly for three months before quietly disappearing: the cabbage soup diet, the blood type diet, the inexplicable period in 2019 when everyone was putting butter in their coffee. Intermittent fasting — the 16:8 model specifically, where you eat within an eight-hour window and abstain for sixteen — has refused to go away, because the evidence refuses to let it.

A landmark 2024 umbrella review in eClinicalMedicine (that's The Lancet, for those keeping score) synthesised results across multiple randomised controlled trials and confirmed that 16:8 consistently reduces fat mass, lowers triglycerides, improves LDL cholesterol, and enhances insulin sensitivity. A Johns Hopkins analysis found that young men who fasted for sixteen hours lost fat while retaining muscle mass — which, if you ask any man who's ever set foot in a gym, is basically the holy grail. The philosopher's stone.

One important caveat: shifting the window without attending to what goes into it won't produce dramatic results. A 2024 study comparing 16:8 to three standard meals found minimal weight-loss differences when calories were held equal. The mechanism is partly about resting your metabolic system between fuel loads — not a loophole that makes the 11pm pizza irrelevant.

Don’t: Coffee Enemas

I’ll give you a moment to fully absorb the concept before I continue.

The premise, for those who have lived well enough to avoid it: brew a pot of coffee, allow it to cool to body temperature, and administer it rectally. The claim is that this "detoxifies" the liver, cleanses the blood, and delivers a unique kind of energy boost that — and we cannot stress this enough — your morning espresso is also capable of providing, through a route that was specifically designed for the purpose.

The Gerson Protocol, a 1920s cancer therapy that mainstream medicine abandoned decades ago, is the original source. Wellness influencers, with their magnificent disregard for medical consensus, revived it.

Let me be direct. Your liver does not accept deliveries through that entrance. The organ responsible for detoxification is a 1.5-kilogram autonomous processing unit that manages hundreds of biochemical reactions daily without any external input, least of all caffeinated assistance via the back passage. The "toxins" being flushed do not exist in the quantities claimed. The colon's bacterial ecosystem — the microbiome you are presumably trying to nurture with your probiotic supplements and sourdough starter — is actively disrupted by the process.

The risks are not theoretical. The FDA has documented cases of serious infection, electrolyte imbalances severe enough to cause cardiac arrest, and bowel perforation from home-administered enemas. Multiple deaths have been linked to the practice.

If your goal is liver health: drink less. If your goal is gut health: eat more fibre. If your goal is an energy boost: the coffee does work, and at considerably less personal risk, via the route for which your body has two decades of muscle memory.

Don’t: Methylene Blue

Methylene blue is, at its core, a dye. It was synthesised in 1876 to stain biological samples under a microscope and has since found legitimate clinical applications in treating methemoglobinaemia — a rare blood disorder — and as a surgical marker dye. One of its more charming side effects is that it turns your urine a vivid shade of blue, which is presumably why TikTokers love it.

The biohacking community — the same ecosystem that gave us bulletproof coffee, testosterone optimisation retreats, and men who describe their morning routine as a "stack" — has claimed that methylene blue improves mitochondrial function, slows ageing, and produces measurable cognitive enhancement. The rodent studies they cite are real. The human evidence, less so.

Preliminary human trials have not demonstrated meaningful cognitive benefit in healthy adults. What they have documented is the risk of serotonin syndrome when methylene blue is combined with SSRIs or other serotonergic medications — a reaction that begins with agitation and elevated blood pressure and can escalate to seizures and, in rare cases, death. The FDA has issued explicit warnings.

You are, in practical terms, performing an unsanctioned pharmaceutical experiment on yourself using a Victorian microscopy dye, based on findings in mice, in pursuit of a cognitive edge that has not been demonstrated in humans. The risk-benefit ratio does not work in your favour. There are cheaper and safer ways to feel like you're performing at the edge of your biology. Most of them involve sleeping eight hours.

Don’t: Eat Raw Liver

We have arrived at the entry that required the most emotional preparation to research.

The carnivore community — an enthusiastic subculture organised around the belief that humans should eat exclusively animal products, preferably raw, preferably organ-based, and ideally in a way that is maximally inconvenient to photograph on a date — has made raw liver its emblematic food. The claim is that cooking destroys vital enzymes, strips out nutrients, and somehow diminishes the ineffable masculine vitality residing within the organ. Prominent influencers bite into frozen bison liver on camera. This content has, between them, hundreds of millions of views.

Raw liver is a reliable vector for salmonella, E. coli O157:H7, listeria, and — depending on the animal and its provenance — tapeworm larvae and toxoplasma gondii. These are not hypothetical hazards attributable to mass-produced factory farming that your regenerative bison ranch has transcended. They are biological realities. The NHS and FDA both maintain explicit guidance against consuming raw or undercooked liver. The enzymes that advocates insist are destroyed by heat are not, in fact, special digestive compounds with systemic effects — they are the liver's own cellular machinery, which your gut would dismanttle and absorb as amino acids regardless of whether it was cooked or not.

Cook the liver. Flash-fry it with butter, shallots, and a splash of Madeira if you want to approach it with any self-respect. Your nutritional outcome will be essentially identical, and you will not be admitted to hospital for a preventable parasitic infection. That is a reasonable trade. It is, in fact, the only trade.

**

Men's health is not complicated, and the wellness industry's $6 trillion turnover depends on you believing otherwise. Sleep enough. Move regularly. Eat food that was recently alive. Drink less than you probably do. These unglamorous fundamentals will outperform virtually every supplement stack, bio-optimisation protocol, or rectal intervention currently being sold to you at scale. The cold plunge is a legitimate tool. Time-restricted eating is a framework worth adopting. The rest is expensive folklore.

Your body is not a start-up in need of disruption. It is a 200,000-year-old piece of engineering that has survived ice ages, famines, and the invention of cigarettes. It mostly just needs you to stop trying to upgrade it with a fish-tank dye and some frozen bovine organs. And perhaps — radical thought — to go to bed at a reasonable hour.
