Ok I'm posting the twitter link bc the wsj article is pay walled and it summarizes it.

Eli Lilly released retatrutide Phase 3 data yesterday. 28% weight loss in 80 weeks. The most powerful obesity drug that’s ever been tested.

And today the cancer signal drops.

12,112 patients. Seven tumor types. GLP-1 users had half the lung cancer metastasis rate (10% vs 22%).… https://t.co/wqMGXWckw0

12,112 patients. Seven tumor types. GLP-1 users had half the lung cancer metastasis rate (10% vs 22%). Breast cancer: 43% cut. Colon cancer five-year mortality in a separate study: 15.5% vs 37.1%.

these effects are clearly beyond just weight loss, GLP agonists are showing more and more effects it's exciting stuff.
 
Hopefully these kinds of findings will eventually get to the bottom of what's really causing all these things (already-identified metabolic syndrome aspects; joint pain; mental health imbalance; cancer) which are mitigated by GLP-1 endruns. But clearly not root-caused by natural GLP-1 bioavailability problems, I believe.

You better get on the wagon now because Lilly already hiring PI's and cooperating with authorities in seizing shipments of peptides across the country. It's only going to get worse from here. Buy now, stock up and observe what happens next.

No secret that I love Reta. My avatar is even a Reta molecule. But, if the FDA caves in and they make Reta a biologic (waves magic wand), then the clampdown will get more intense than it is now, which is saying a lot.

Actually, the effects are probably directly driven by the weight loss process (at least thats the theory). When you deprive the body of fuel, you deprive the cancer of fuel. So not the reduction in weight, which would be likely to reduce the rate of new cancers, but the process of losing weight which is impacting existing cancer growth.

This is my thought as well. People forget that being obese IS a health risk for many reasons, including that higher amounts of body fat are associated with an increased risk of a number of cancers.

So already getting down to a healthier body weight, has many health benefits associated to it.

Either way, interesting results from the phase 3 data, thanks for sharing.

They are seeing results outpacing just standard weight loss. It's partially the blood sugar control, same reason metformin is used in cancer treatment but there's more going on. Inflammation drops way faster on glps than it does on equivalent calorie restriction or fasting, the elimination of liver fat on Reta is far more effective than weight loss alone etc.

Where's the data/paper?
 
I saw study a year or so ago with bowel cancer patients living a lot longer on GLP drugs than those not on GLP drugs. If this keeps getting confirmed, it might be that GLP-1 agonists are a very effective treatment for cancer, or at least surprisingly good at preventing it from spreading. This study is showing only half as many metastases ( secondary tumours ) in several different cancers if on GLPs , many cancer therapy drugs are not that good, and typically have much worse side effects. And it probably prevents a lot of cancers in the first place. Those results are easily good enough to support large scale prospective clinical trials to prove the effect is real.

this is one of those situations where we are finding out more and more that these drugs do something and then retroactively figuring out exactly why and how they do that

I was wondering why <50% didn't appear on this thread. Must be the time gap, eh? I can visualize you chomping down on a big fat Cuban, with a smug smirk and a nod, reading this thread. Yet, I haven't seen your take on the future of the grey zone if Reta becomes legit approved. What changes do you predict will happen for us common yeomen?
 
I believe people stating that these results are just a subproduct of weight loss are cutting it too short. It's not the first time I read about similar results on top of what would be expected with regular weight loss.

I also remember listening to a podcast by Dr Attia saying we don't actually know if obesity itself causes cancer, and he doesn't believe so. But things like insulin resistance could be the culprit
