Why is trying to be healthy so exhausting?

Episode #49: Why being healthy feels like a second job, what conflicting health advice and the illusory truth effect do to your brain, and the Grain of SALT Test for deciding which health advice deserves a place in your life.

The podcast is baaaaaack!

After a long summer break, and 10 months and 13 countries on the road, new episodes land every Friday. Follow so you never miss one: Apple Podcasts, Spotify, YouTube, or right here in the Substack app.

I’m bringing deep dives, interviews and video, so let me know how I could make the podcast better and the type of content that would be the most useful to you.

This first one was recorded in the wardrobe of an Airbnb in Mexico City, so apologies for the poor sound quality!! There was construction noises outside and a massive echo in the living room so that’s the best I could do.

This week’s question: when did trying to be healthy turn into a second job?

Most of us are doing more for our health than ever, and somehow we’re more knackered by it, not less. My theory is that the workouts aren’t the tiring part. As I put it in the episode: “The tiring part of being healthy isn’t really the doing, it’s the constant checking.”

In this episode

  • Why the constant checking wears you out more than the workouts

  • What happened when 631 people saw too much conflicting nutrition news (it didn’t end well for broccoli)

  • The illusory truth effect: why “seed oils are poison” starts to sound true the 10th time you hear it, even when you know better

  • How fibre went from “eat a few more veggies” to fibermaxxing and a mac and cheese with added fibre

  • The Grain of SALT Test: 4 quick questions to decide whether a health trend deserves a place in your life
