One Health Tweak a Week
One small, science-backed change each week - written by an MD PhD for people who want results, not homework.
Most health advice fails for a straightforward reason: it asks too much, too soon.
So this newsletter does the opposite. Each week you get one practical tweak - small enough to do on a busy weekday - backed by real evidence, explained clearly, and turned into a simple plan.
No dramatic “new you”. No 37-step routine. Just steady wins that compound over time.
What you’ll get each week
A 5–8 minute read (clear, structured, skimmable)
One decision rule you can actually remember
A small experiment you can try for 7–14 days
A practical checklist (so you don’t have to “stay motivated”)
Scripts and shortcuts for real life (shopping, meals, routines, travel, stress)
You’ll often see recurring themes (because they matter): belly fat / metabolic health, food that quietly helps or harms, sleep and circadian timing, protein for regular folk, and movement that fits into normal life.
In 2025, One Health Tweak a Week newsletters were viewed over 100,000 times, the podcast was downloaded 15,000 times, and readers left over 1,000 comments. If you’ve come across my work on Medium, those articles have now been read more than 125,000 times - mostly by people who want health advice that’s evidence-based and actually usable.
What readers say
“I love that your tweaks are so science-based… I incorporate your tweaks… I do appreciate them!” - JH, RN
“I read your Substack faithfully and try to implement the tweaks. I share your articles with family and friends.” - CP
“Personally, I take almost all of your tweaks and incorporate them into my own life… The best one was to stop eating 3 hours before going to bed… I do send them on to family too.” - JC
“I look forward to Saturday mornings… to read and absorb your well-written… highly personally relevant articles…” - JR
Start here
Here are a few popular issues from recent months. Choose a first read that feels most relevant.
The Only Food List You’ll Ever Need for Healthy Ageing?
It’s a safe bet you’re here because you care about your future self - you want the choices you make today to pay off in extra years of strength, sharpness, and independence.
Drift Off and Stay Asleep: 7-Night Sleep Experiment
Years of nights on call as a junior doctor have trained me well: if my head touches a pillow, I’m out, so I told myself I didn’t have any sleep problems… until I started digging into the background for this issue.
The Gut-Friendly Carb Linked to Longer Life
The other night, I was staring at a cold potato, wondering if it was a superfood - (as one does!)
Who this is for
This is for you if you:
want clear, calm guidance without the influencer noise
prefer simple rules over perfect plans
care about longevity, energy, and metabolic health - and you’d like your habits to match that
enjoy evidence, but don’t want to spend your evenings reading PubMed
Who it’s not for
If you want a rigid meal plan, daily macros, or an all-or-nothing programme, you’ll probably find this irritating.
If you’re mainly after quick fixes, miracle supplements, or dramatic before-and-after promises, this won’t be your kind of thing.
About me
I’m Ben Jones, MD PhD. I’ve worked in hospital medicine and research across the UK, the US, and Africa, and I now write practical, evidence-based health guidance.
My work on Medium has been read by tens of thousands of people, largely because I’m stubborn about two things:
1. Being honest about what the evidence can and can’t say, and
2. Turning that evidence into changes that are actually doable.
A small promise
This newsletter won’t ask you to overhaul your life.
It will help you spot the one lever that’s most worth pulling this week - and make it easy to pull.
I’ll see you inside!
