I think you still have to eat less.

Robert Lustig's Sugar: The Bitter Truth hammers on fructose being a major culprit to weight gain:

https://www.youtube.com/watch?v=dBnniua6-oM

Dr. Gil Carvalho (medical doctor, research scientist, science communicator) debunks parts of Lustig's 30-year-old claims:

https://www.youtube.com/watch?v=vdoDx9dIuNE

Nonetheless, Dr. Carvalho agrees with the sugar drinks part:

"We have a lot of recent evidence, recent studies after [Lustig's] talk. The link between soda and weight gain and obesity and other chronic diseases is quite strong."

Drink fewer sugary beverages, consume fewer calories (eat less), exercise, and drink less alcohol.

One of my reports at work started out with heavy diabetes and 300 pounds. Now he’s down to under 200 and has no diabetes less than 5 months later.

If you're getting it compounded it may be time to switch providers.

Seriously, in the first week you should feel a bit of nausea at .25mg. After 2-3 weeks you should see something, either weight loss (most) or gain (some).

Or you could be one of those who have no effect, which sucks. I'd go over your process with your provider, from storage to injection.

esskay•3m ago
Not everyone gets nausia. On .25 I had zero side effects. At .5 minor sulpher burps that lasted a few days and then again down to zero side effects. In the online communities of people on GPL-1 very few people have side effects.

Why on earth would having no side effects suck? As long as its working (weight loss) then thats the ideal scenario.

glp1 doesn't increase your basal metabolic rate, it curbs your appetite. so it's still possible to ingest an excess of energy and to maintain your energy storage volume if you continue the dietary habits that got you fat in the first place -- eating slop and/or eating for the sake of eating.

even one caffeinated corn syrup slurpee that people consume like it's no big deal can be a quarter or more of your daily energy requirement. a few snacks on top of that and that leaves preciously little budget for real food.

> slows down the accumulation of biological aging markers in the DNA of adults with HIV

And if you don’t have HIV?

Easy to pick it up
MyelinatedT•7m ago
Not really, in most cases! I read up on the per-exposure chances of actually picking up HIV a while back[1] and was shocked at how low the risk is, especially for heterosexual men (4 in 10,000 per-exposure; insertive vaginal sex with an infected partner).

Even in the highest-risk scenario (receptive anal sex) the risk is ~138/10,000 per exposure.

It says 42% of treatment group showed slower aging, and reduction in telomere length... is there an effect size published anywhere?
akomtu•32m ago
I'd be more suspicious of what side effects this thing has.

Been on one for a few years now, it tempered my persistent auto-immune issues. Short term side effects are barely present for me. This stuff has made it so I don't have to be on steroids and antibiotics every other month. I did not start the medication for weight loss purposes, though have lost 10-15lbs, but I attribute that to being off steroids.

Long term? Who knows for sure. Semaglutide has been approved for 9 years. Liraglutide was 2009 and hasn't shown thyroid issues still. Exenatide has been available since 2005.

GLP-1s aren't new and haven't shown widespread negative issues beyond gastrointestinal upset, and that is typically fixed by... drinking more water. The trials in rats have pointed towards potential thyroid cancer risks but those haven't been seen in people.

>They also reduce visceral and ectopic fat that accumulates around the abdomen and organs, which may help curb the inflammatory and metabolic signals that promote aging.

Interesting, I wonder if someone will do a study where they pair a GLP-1 with tesamorelin to see if there's any synergy there in terms of fat reduction and reduced aging.

bethekidyouwant•31m ago
If the DunedinPACE test is so accurate and cheap now, there must be hundreds of people that have a baseline and also measurements after taking GLP’s… also why do you need a double blind if you have this amazing biological ageing test?

Why the sad face?
ck2•24m ago
but what about the people with a BMI already under 20?

not like we can take GLP-1 even if it was affordable

btw soluble fiber helps people naturally secrete more GLP-1 but of course not on the same level as a dedicated drug

maerF0x0•18m ago
Once at optimal bodyfat/weight afaik CRON diet is the long term solution?
barake•15m ago
What's preventing you from taking a GLP-1 with a BMI under 20? I started semaglutide with my BMI at 19.
WalterGR•8m ago
How did you get your prescription?
froobius•22m ago
Isn't being "underweight" generally shown to reduce the speed of aging
maerF0x0•19m ago
Came here to say this. Also caloric deficits.
y-c-o-m-b•21m ago
I'm excited to see more studies done in this context, but without the HIV association. My wife has Ehlers-Danlos Syndrome and Rheumatoid Arthritis. She saw more benefits in inflammation reduction than weight reduction, especially those first two weeks she started taking it. She says her pain levels are night and day difference when on GLP-1 vs off. To me it would then make logical sense that reduced inflammation can have a measurably positive effect on aging.
Murfalo•19m ago
Let's play spot the conflict of interest. Three of seven authors tied to a company selling biological aging tests. One consults for Merck, GSK, etc.

There seems some promise at times but I also struggle to see the recent slew of "GLP-1s cure X", where X is seemingly any ailment known to man, as much more than the next Big Pharma gold rush where the profits dwarf any eventual regulatory fines, and taxpayers and real patients are left with the costs.

epistasis•12m ago
I am EXTREMELY skeptical of epigenetic clocks at the moment, and have been for a few years, but at the same time it's important for these clocks to be investigated and shown to be what they are.

Even though I personally expect to be readouts of things that don't affect healthspan much, I don't have any more evidence than those trying to work out what they are. I've been wrong before, and also most tech development does not end up living to its promises, but without the investigation we'll never know.

> Big Pharma gold rush where the profits dwarf any eventual regulatory fines

With pharma malfeasance, the penalties are actually big enough, unlike most other fields. Unless you have something particular in mind?

> I am EXTREMELY skeptical of epigenetic clocks

I hear that word and I immediately think of "that" guy that runs the cocktails of additive interventions to "improve" it.

They also cause sexual dysfunction while you're taking them. Not a problem I guess when you're overweight, but on weight...it's a huge problem.
mannyv•6m ago
That's not a common side effect, and I've been watching GLPs for years. In fact, it's more likely to cause divorces due to, you know, becoming more attractive.
esskay•2m ago
Or put another way, "Let me pluck one of the rare side effects and make it seem like its a common one because I know nothing about this"
mitxela•13m ago
Presumably mediated by caloric intake reduction, which is already known to slow aging?
NiloCK•13m ago
If two cars are each three years old, but one has had twice as much gas consumption as the other, which would you expect to show more wear on its comppnents?

Caloric churn is putting the body's systems through their paces - at the very least for everything related to digestion. But really most of life is well described as pieces of a metabolic process.

m3rc•11m ago
This is such an oversimplification of complex biological processes that it borders on medieval superstition.
echelon•11m ago
Oxygen is a reactive species, that's how we do what we do. How we swim the thermodynamic eddies and flows across quadrillions of chemical reactions.

But burning that fuel is damaging.

dozerly•9m ago
Comparisons like this, while seeming to make sense using “common sense” rarely impart any value or scientific meaning. Maybe it works like that, maybe it doesn’t.

If as a result of less caloric consumption you’re starving your cells of needed nutrients, maybe that’s the one that degrades earlier.

dimes•6m ago
Should we similarly expect those who use their muscles more to be in worse condition than someone who doesn’t exercise?

This feels like the early days of medical marijuana where everything was sunshine and rainbows, and then 10 years later we realize yes, there are still drawbacks.

It would be pretty funny if it turns out it doesn't have any side effects and it really is just a silver bullet.
efficax•5m ago
FDA approval of the first GLP-1 agonist was in 2005 and many diabetics have been taking these drugs for close to 20 years, so we have a pretty good picture of what long term side effects are: mostly GI symptoms, and you can have problems with muscle loss and bone weakening if you lose a ton of wieght. otherwise they are well tolerated.
5m ago
If a car sits idle for months at a time, its rubber seals and gaskets will degrade faster ... so, obviously, according to this bullet-proof analogy, a human that doesn't exercise will be in worse condition.
