The GLP-1 landscape is about to get much more complex. Eli Lilly's retatutride hits three receptors versus the current drugs' one or two and has completed Phase 3 trials. Oral versions are coming. Within five to ten years, there will be many more options targeting specific side effects, muscle preservation, and different administration routes.

Manoush raises two real-world encounters that made her uneasy. At an American Heart Association meeting, she heard researchers propose using GLP-1s preventively in kids in high-obesity communities — and worried this was reaching for a pharmaceutical quick fix before addressing root causes. At a separate conference of wealthy individuals, she saw GLP-1 use framed purely as optimization: not treating disease, but maximizing performance. Khullar validates both concerns. The evidence base for GLP-1s covers overweight adults and people with chronic conditions; preventive pediatric use and performance microdosing lack data entirely. More broadly, he worries that a sufficiently powerful drug becomes a political escape valve — reducing pressure to fix food systems, built environments, and social determinants of health. He's the first to want systemic change, he says, but also honest that decades of effort have yielded little progress, making the case for better access today.
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.
