Dr. Chris Thompson describes how AI systems can grade a surgeon's procedure at the end, specifying metrics like percentage of full-thickness sutures and suture spacing — with the standard that 100% of sutures should be full-thickness, and a rate of 70% is not good. Currently in research centers only.
Dr. Chris Thompson says some people stop GLP-1s because they don't want to inject themselves once a week, that taking a medicine orally every day makes it hard to remember, and that ramping up to the effective dose causes side effects — though there are ways to do that safely going step by step. Nausea and muscle loss are side effects of some GLP-1 medications.
Consequential creator advice requires independent verification before Today can promote it.
Dr. Thompson suggests you stay full longer with a big, heavy fat and protein meal, probably because of PYY, and notes PYY has been very hard to drug but is very potent.
Speaker hedges ('I think', 'probably').
The magnetic small bowel anastomosis produces big spikes in GLP-1; practitioners are now combining it with an endoscopic suturing procedure, together replicating a full gastric bypass, yielding GLP-1 hindgut spikes, vagal afferent restriction signaling, suppressed ghrelin, and remarkable weight loss.
Huberman raises the concern that a patient might figure out they can eat greasy, fatty junk food that pushes ApoB through the roof and think it's okay because it doesn't show up on their continuous glucose monitor. He then counters that this worry underestimates patients, who are generally trying to do the right thing.

GLP-1 drugs are not targeting a deficit; they are augmenting normal physiology, ramping GLP-1 levels up a thousandfold over what even the healthiest person would have.
Thompson is involved in a healthcare delivery platform called Everself. It starts by collecting data — weight loss outcomes, stitches placed per procedure, procedure time, complications. The next layer puts AI on top of the data so it can coach through the procedure and give a grade at the end: how many sutures were full-thickness (you want 100%; 70% is not good), how many were close enough together versus too far apart, the pattern used, and the volume of stomach reduced.
Dr. Thompson notes that blood tests for testosterone, estrogen, luteinizing hormone, lipids, small LDL, and ApoB are now routinely available, that 15-20 years ago getting a blood test without a motivating problem cost thousands of dollars and was hard to find providers for, and that blood testing is now trivially inexpensive for most people — with biopsy screening heading in the same direction.
None stated.
Andrew Huberman notes that canker sores and ulcers were long understood to be caused by stress or mouth wounds, and that hundreds of millions or billions of people across history would say stress gives people ulcers — so something more than the bacterium is going on. Dr. Chris Thompson adds that H. pylori needs to be treated when present.
reasoned inference, not established fact
Ghrelin resides in the fundus of the stomach. Researchers in Germany developed the idea that fundal ghrelin cells can be ablated because they live in the mucosal layers; argon plasma coagulation can be sprayed over the fundus to kill off ghrelin-producing cells. The ablated cells grow back, but there are not many of them. Adding fundal ghrelin ablation to ESG increases weight loss from about 18% (ESG alone at a top center) to over 20%, maybe 25%. There are no drugs that effectively inhibit ghrelin.
Dr. Sara Gottfried explains that blood testing for hormones is a quick snapshot taken while the needle is in your vein for about 30 seconds, and is not as comprehensive as dried urine testing.
Dr. Sara Gottfried states that a coronary artery calcium score almost gives you a fork in the road in terms of how much you need to pay attention to cardiometabolic health as a woman, and that if you're 45 with an elevated CAC score, or have PCOS or other biomarkers trending toward the number one killer, you should start making cardiometabolic changes.
Dr. Sara Gottfried describes chronic cardio (lots of cardio without resistance training) as an anti-pattern that doesn't always serve people and tends to raise cortisol levels in runners and marathon runners. She says you can buffer that cortisol effect with vitamin C, and recommends switching to adaptive exercise like Pilates and yoga to lower cortisol.

Dr. Sara Gottfried describes that oral contraceptives reduce the risk of ovarian cancer by about 50% when taken for about five years, but also increase inflammatory tone, raising high-sensitivity CRP by about 2-3x.
The lab uses a transgenic Alzheimer's rat model that develops amyloid and tau pathology in the hippocampus in an age-dependent fashion. The vagal nerve stimulation device used in the lab is sutured to the stomach and sends electrical stimulation to the nerve only when the animal is eating, driven by the natural expansion and contraction of the stomach. Vagal nerve stimulation devices have been shown to rescue memory impairments caused by an unhealthy diet in animal models. There may be a functional benefit of vagal nerve stimulation in models of memory impairment, but this research is still in the baby stages.
early-stage animal research
In rodent models fed a Western diet, exercise can reverse memory deficits, in part through changes in the brain. In rats fed an unhealthy diet that later exhibit longstanding memory deficits, exercising can rescue those deficits.
animal evidence
Dr. Kanoski reports that the social facilitation of eating phenomenon requires oxytocin signaling in the hippocampus; when this signal is genetically turned down in rodents, the animals no longer show the effect.
Described animal-model finding.
Dr. Kanoski describes the phenomenon of social facilitation of eating, in which people eat less alone but eat more when eating with a group, and even more when the group is familiar. He notes rodents show the same phenomenon.
Described phenomenon with high confidence.
Dr. Kanoski describes that there are a lot of potential issues with GLP-1-based drug use in lean individuals that we do not have any grasp on, because those clinical trials have not been done and probably will not be. He also notes it is now a whole new world where people who do not need GLP-1 drugs can get their hands on them.
Described concern about an evidence gap, not a measured risk.
The reward pathway can be engaged by bland healthy food when an animal is food restricted, by water when water restricted, and by sodium in a sodium-depleted animal. Dr. Kanoski describes this as very much dependent upon the animal's state, illustrating state-dependent reward valuation.
Described with high confidence (0.95) from animal research.
