This week Laura sits down with Dr John Loy, one of the busiest weight-loss surgeons working between Ireland and the UK. He grew up behind the bar of a family pub in County Down, which he says was the best training in medicine he ever had, before a chance meeting in New York changed how he thinks about the whole job.
It's a warm, funny and genuinely eye-opening conversation about obesity as a disease rather than a choice, and about the person on the other side of the desk. John explains why more than half of his patients cry at their first appointment, why he never asks how much weight they've lost, and why the goals that matter are seeing your own child's First Communion from behind the camera — not the number on the scales.
He also gives one of the clearest explanations you'll hear of how weight-loss surgery actually works - the gastric balloon, the sleeve and the bypass - why a bypass is like \"a free GLP-1 injection every day for life\", and why, despite the rise of the weight-loss injections, demand for surgery is climbing rather than falling.
Obesity is a disease, not a choice
John argues it should be treated in stages, like cancer, and that denying people care on a BMI cut-off is simply wrong.
A gastric bypass is like \"a free GLP-1 injection for life\"
The surgery isn't just about a smaller stomach; it changes the gut hormones that tell your brain you're full.
The weight-loss injections haven't ended surgery — the opposite
Many patients try the injections first, stall or can't afford them, and find a sleeve pays for itself within a few years.
Three procedures, three different jobs
The swallowable balloon, the sleeve and the bypass each suit a different stage — John explains who each one is for.
Blood sugar settles before the weight comes off
Diabetes can resolve within days of surgery, long before any weight is lost — proof of how closely the gut and brain talk.
The best consultation starts with \"why are you here?\"
Rather than judging, John asks patients their story — and finds the roots often reach right back to childhood.
Non-scale victories are what matter
He never asks how much weight a patient has lost; he asks whether they can finally take their kids to Disney World.
A childhood in the pub was the best training he ever had
Learning to talk to people across a bar counter, he says, taught him more about medicine than any exam.
