I walked Japan’s old Nakasendo trail two summers ago. The warning signs there have always carried bear bells. And it’s worth knowing what they’re actually for. You wear a bell so a bear hears you coming, because historically bears avoid people. The sound gives them the chance to stay away. Back then, locals told me the monkeys were the real nuisance, not the bears. But on my recent trip I heard bells everywhere, on packs, on trails, even in Tokyo, far more than before. So here’s the honest question: if bears have always kept their distance, has something shifted? I’ll leave that one open. Not to scare anyone, but to walk with care. Wear a bell. Carry bear spray if you can get it. And don’t walk alone. I’m 57. Not the expert, the experiment.

Seven things I noticed in Japan that quietly keep men fit into their 70s. None of them are diets.
1. Walking everywhere, not as exercise, as life
2. Stopping at 80% full (hara hachi bu)
3. Tea, black coffee over fizzy drinks
4. Fish and soy before red meat
5. Smaller plates, hand-sized portions
6. Floor-sitting = free daily leg strength
7. A reason to get up (ikigai), no retirement cliff For men over 40, it’s not one big change. It’s seven small defaults that stack. I’m 57. Not the expert, the experiment. Which one would you actually try? bodyrecomposition

43,000 people. 7 years. One habit separated the longest-lived from the rest, and it wasn’t fitness or money. The Japanese call it ikigai. Not some grand “find your purpose” mission. Something smaller and far more useful: a reason to get up tomorrow. For men over 40, that daily reason is the engine. It’s what gets you out walking, training, moving. And movement is what keeps you lean past 50. Mine’s the dog and the first coffee. And my wife. Ok - that’s 3 ;) Not the expert, the experiment. What gets you up? bodyrecomposition

One day after I left Utsunomiya, a bear was roaming the city centre, the exact streets I’d been walking around. Not a remote mountain. A city. That’s how close Japan’s bear problem has got, with record sightings and bears appearing near stations and town centres. So here’s what Japanese guidance actually says if you encounter one:
1. Do not run. Running makes you look like prey.
2. Stay calm, back away slowly, keep facing the bear, talk in a low voice. No screaming or high-pitched sounds.
3. If contact is unavoidable, lie face down with your hands protecting the back of your neck, shielding your vital spots. Know this before you go, not after. If you walk alone to stay fit, especially over 40, it could matter one day. I’m 57. Not the expert, the experiment. 🤙

The Okinawans have four words for it: hara hachi bu. Stop eating at 80% full. Sounds soft until you know the science: your gut takes about 20 minutes to signal your brain. So 80% full now becomes 100% by the time the plate’s empty. For men over 40 trying to lose fat, it’s the simplest brake there is. No app, no tracking, just the fork down a little early. I’m 57, more than three decades as a psychologist, twenty of them clinical. Not the expert, the experiment. Would you try it? 🤙 bodyrecomposition

Japan just hit a record: over 50,000 bear sightings in a year, double the previous high, and the worst casualty numbers in a decade. Bears are now turning up near stations, schools and city centres, not just mountains. The truth nobody wants to hear: the best way to survive a bear encounter is to never have one. I was walking alone by a river in Nikko and something felt off. Overgrown path, low visibility, no one around. I turned back. Later I learned bears often travel along rivers. The unease was justified. If you walk to get your steps in, especially over 40 and especially alone, these are the rules: avoid dawn and dusk when bears feed, make noise as you move, and if you can’t see ahead and you’re on your own, turn back.

10,000 steps a day was never science. It started as a 1960s marketing slogan to sell a Japanese pedometer called the manpo-kei, literally “the 10,000-step meter.” We’ve been chasing an ad campaign for 60 years.
And here’s the irony: Japan also gave us something far better. It’s called interval walking training. Three minutes brisk, three minutes easy, repeat five times. Thirty minutes and you’re done.
In the original study, the interval walkers beat the steady-pace walkers on basically everything. Leg strength up around 13%. Aerobic fitness up around 10%. Systolic blood pressure down. Same shoes, half the time, better results.
So when I was walking all over Japan, I wasn’t grinding out 10,000 steps. I was doing three by three. Brisk enough that talking gets hard, then easy enough to recover. Repeat.
Steps still count. This is just a smarter, stronger way to spend the time, especially in your 50s when holding leg strength matters more every year.

Week 1 of a real fat loss program, at 57. Here’s the honest version, not the highlight reel.
First, the question I get most: two doctorates, training since I was 14, so why hire a coach? Two reasons. Accountability, and less thinking. On my own I second-guess everything, tweak the macros, move the goalposts, talk myself out of it. With a coach, I just execute. He decides, I do the work, I trust the process.
The numbers: 1,761 calories a day. 165g protein. 45g fat, 175g carbs. Four workouts a week. 10,000 steps a day.
Now the bit nobody warns you about. By midweek I was properly tired. There’s a reason: when you cut calories, your body quietly tries to move less to save energy. It nudges you toward the couch all day. I felt that pull hard, and I hit my 10,000 steps anyway. That’s the real work, not the gym hour, the 23 hours around it.
And the scale? Week 1’s drop is mostly water, not fat. When you start a deficit you burn through stored glycogen, and glycogen holds about three times its weight in water. So the big early number is real, but it isn’t fat. I’m not celebrating it. I’m just showing up, every week, and bringing you with me.

Whey protein’s up about 48% to the shopper in 18 months, and it’s still climbing. There’s a genuine global shortage building, and the reason is wild: the GLP-1 weight-loss drug boom needs high protein intake, and it’s eating into the world’s whey supply. So here’s what I actually do.
Skip the buzzwords. “Grass-fed,” “isolate,” “premium blend” often just means pay more, and isolate has jumped the most of all.
I drink plain unflavoured whey concentrate. WPC. It does the job for most of us, unless you’re very sensitive to lactose. And I have it unflavoured on purpose: no sweeteners, artificial or natural. For me, less is better.
If whey gets silly where you are, pea protein’s come a long way from the chalky stuff. The research now puts it about level with whey for building muscle, if your gut handles it. I don’t use it myself, but it’s a solid option to keep your costs down.
Read the protein per 100 grams and the ingredient list. That’s the whole game.

High protein yoghurt. The word that charges you extra. So I checked.
A premium “protein” tub: about 10g a serve, at a premium price. The plain Greek beside it: 9g, for half the cost. You’re paying extra for one gram and a buzzword.
Worse, some sneak in oligosaccharides to fake that thick, creamy mouthfeel, as well as other stuff like inulin. Yes, it’s a fibre, but it really doesn’t agree with me. Maybe you too.
Flip the tub. Check the nutritional facts. Make it high protein, low sugar, short ingredient list. Unless you hit this week’s special, usually you’ll find that’s just plain Greek yoghurt. I’m in NZ, but check your own shelf, the rule travels.
