More than half of patients stop GLP-1 medications within a year, whether from side effects, cost, or access. The sticker price can hit $1,300 a month. The drugs also cause muscle loss alongside fat loss, raising frailty concerns — which is why high-protein diets and strength training are essential companions. These are not simple, affordable, or side-effect-free drugs.

Manoush recalls the 1990s cultural shift when addiction began to be framed as genetic and neurobiological rather than a moral failing. She asks Khullar whether GLP-1s represent a new chapter in that evolution. He says yes — but stigma persists. Then he shares something deeply personal: he underwent the same fMRI protocol used with clinical trial participants, viewing photos of food and alcohol while his brain was scanned. The result was striking. His brain showed almost no activity in response to alcohol images; those with alcohol use disorder showed dramatically elevated responses in the same regions. That contrast — visceral, visual, and personal — drove home what years of medical training had only told him abstractly: much of addictive behavior is neurobiologically predetermined, happening before conscious decision-making even begins [1] — Dhruv Khullar "Dhruv Khullar underwent the same MRI protocol as clinical trial participants, viewing images of food and alcohol while his brain was scanne…" 28:55 .
Beyond weight and diabetes, GLP-1s appear to slow or reverse fatty liver disease, chronic kidney disease, and osteoarthritis — and may reduce cardiovascular and stroke risk. Some effects appear independent of weight loss, pointing to a possible anti-inflammatory mechanism. Even a physician who approached these drugs with skepticism has been repeatedly surprised by the evidence.
Studies show GLP-1 medications can slow or even reverse fatty liver disease and chronic kidney disease, effects that appear independent of weight loss.
Predictions that AI would eliminate radiologists were spectacularly wrong. Since those predictions, Mayo Clinic's radiology staff grew 55% and the specialty became the second-highest paid in medicine. The reason: AI automated scan-reading, but only 36% of a radiologist's time was ever spent doing that.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
