  Using a large database of (deidentified) medical records, the researchers compared the outcomes of people taking a GLP-1 for their type 2 diabetes to people taking other common diabetes drugs between 2017 and 2025. GLP-1 users were significantly less likely to be diagnosed with TB for up to a five-year span, they found.Both of these studies are observational and retrospective, meaning they can only show a correlation between GLP-1 use and reduced (or at least less severe) infections, not prove a direct cause-and-effect relationship. At the same time, these are the only latest pieces of evidence pointing to a genuine germ-busting benefit from GLP-1 drugs.I wonder if the likelihood that people taking a GLP-1 are probably better off financially, have a health care provider willing to spend on the drugs (and therefore probably a better medical system) or a combination of these and other traits are the real reason there are fewer infections.

  I was at a hepatology meeting focussed on fatty liver a couple of years ago, where a well regarded head of hepatology at a major national quarternary referral centre, joked that we should be putting this in the water supply...

  Maybe being overweight is bad for the immune system

  Could be due to better control of blood sugar. E.g. lower blood sugar increases inflammation, decrease immune response and provides bacteria a readily available source of food.

  How expensive are GLP-1s again?
• cromka
  Inam betting it's because of lowered inflammation allowing for stronger immune response.

  This study is questionable because, where I live, TB is not a disease that happens to just anyone; it usually happens to people in poorly sanitized places with lower socioeconomic status. But pharma giants are going to publish ghost studies; they simply have too much money not to use it to further their drug empire.Severely cutting calories while staying sedentary trashes the immune system, disrupts hormones, impairs reproductive function, and strips away bone density and muscle?If this happens to high-performing athletes, there is no reason to believe sedentary folks are immune. The research behind Relative Energy Deficiency in Sport breaks down these exact mechanisms: https://en.wikipedia.org/wiki/Relative_energy_deficiency_in_...GLP medications blunt your appetite so you eat less, but you still end up feeling completely drained because your body lacks fuel. The goal should never be just blindly slashing calories. You have to feed your body what it needs rather than solely cutting what it craves, and GLP drugs cannot distinguish between nutrient-dense meals and the junk food binges you are trying to avoid.They do not fix metabolism, either. Any claimed "metabolic boost" has never been proven beyond a minor 100 kcal increase in resting metabolic rate (RMR). Most people pushing that claim rely on an older study where glucagon raising RMR was merely an interpolation by the authors. To put that in perspective, a 100 kcal bump is less than two slices of bread, which sit around 130 kcal.Being healthy is not just about avoiding excess body fat. Look at retired sumo wrestlers: they carry significant weight, yet their health markers crater once they stop training while keeping their diet identical. Real body fat reduction requires higher activity levels, but most GLP users fixate entirely on scale weight. Crashing your intake on high doses also sets you up for serious bile and gallbladder complications down the road.Give it a few years, and we will look back on handing GLP prescriptions to people who are only 10 to 20 kg overweight as a major mistake. You do not have to gorge yourself to gain weight. Dropping into a sedentary lifestyle reduces muscle mass, lowers your RMR, and tanks your daily energy expenditure, pulling your maintenance baseline down with it. Once your maintenance drops, running a tiny surplus of just 100 kcal a day for four years will easily pack on 20 kg of fat.

  i can kinda get how a glp-1 can be a miracle drug for weight: if we assume that simple molecular fixes to problems will eventually be found by evolution, then when we change our environment rapidly (e.g., with cheap bountiful calories) then this presents an opportunity for a miracle drug, since evolution will take some time to find the fix.but for something like reducing disease infection, i find it a lot harder to understand why we don't create this naturally unless there is some equal-but-opposite cost that we'd incur, or if there is not actually as big of a benefit as we believe (or if this is all just colinear with the weight loss stuff).note: i have no background in any of this and have no idea what i'm talking about

  Kind of kidding, but can we just put GLP-1s in the water supply already? So many benefits!

GLP-1 users were significantly less likely to be diagnosed with TB for up to a five-year span, they found.This is incredibly manipulative. So, we're going to ignore all other factors that may have played into this and just assume it was due directly to GLP-1 use?
