What began as a diabetes drug keeps revealing new capabilities. Ricks walks through the cascade: inflammation reduction (GLP-1s appear to be powerful anti-inflammatories, relevant to arthritis, asthma, psoriasis), and then the stranger, harder-to-explain behavioral effects. Patients in trials spontaneously drank less alcohol, gambled less, and shopped less online — without being asked or prompted. The mechanism, Ricks theorizes, is that alcohol is chemically close to glucose, and the same brain signaling that reduces sugar cravings quiets alcohol desire too. Critically, he pushes back on the 'joy kill switch' narrative: people don't lose pleasure, they just find less appetite for excess. Lilly is now running Phase 3 trials on brenepatide for alcohol use disorder. On pain: retatrutide, the triple-acting drug expected to launch next year, showed the most powerful knee pain reduction ever recorded pharmacologically — a finding with enormous implications given the scale of chronic pain in America. Cancer connections remain observational but are striking: people on GLP-1s for 5–6 years appear to have lower rates of colorectal and breast cancer.
Lilly's triple-acting GLP-1 drug retatrutide, expected for launch next year, produced the most powerful pharmacological pain reduction ever recorded for knee arthritis. The finding was unexpected and points to GLP-1s as potential game-changers for America's massive chronic pain burden.
Obesity is described as a 'nodal health condition' connected to more than 200 chronic diseases, making GLP-1 treatment uniquely high-leverage.
Patients in GLP-1 trials spontaneously reduced alcohol intake, gambling, and even online shopping without being prompted. Lilly is now pursuing a Phase 3 drug — brenepatide — specifically for alcohol use disorder, as the mechanism appears to quiet hedonic urges broadly.
Lilly is pursuing brenepatide in Phase 3 trials specifically for alcohol use disorder, after observational data showed GLP-1 users spontaneously drink less.
US drug pricing is systemically regressive: the largest institutional buyers get the lowest prices, while uninsured or underinsured individuals pay the most. Lilly created LillyDirect to let consumers buy directly at institutional prices, cutting Zepbound's cost by 60% to $399/month.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
