Isn't GLP-1 creating a "feel-good" starvation? Patching the receptors telling the brain one is not hungry and then just letting the body starve happily, leading to significant muscle loss and aged face? Contrary to e.g. water fast where the body switches to 100% ketosis that can run as long as there is any fat in the body and one supplements electrolytes (Mg/K/P/HCO3) and vitamins (predominantly B1/B2/B3), leading to…

Muscle loss is determined by your protein intake, muscle stimulus, and rate of weight loss. Plenty of people start lifting for the first time (or after having stopped for extended periods of time) when going on GLP-1s and actually put on muscle mass. It might result in more loss of buccal fat than otherwise but even that is not definitive. Activating the receptors is not the same as burning fat - there are GLP-1 rece…

n=1, been lifting weights for 25 years and lost 40 lbs on Zepbound and counting.

I can still do my routines easily with no issues. My muscles look slightly smaller I think, but maybe that's the fat around them that's been diminished.

Thanks for the reply. Your perspective framing this as "willpower" is precisely what I'm concerned about. I didn't need any willpower to do this and I'm not even humblebragging nor think of myself as a tough guy. I'm saying that healthy habits are simply a matter of understanding. If someone wants to take GLP-1 on top of that, it's their call. Many seem to be under the impression it's so vital for their specific situ…

Sorry, you're right. I meant that I did not make significant changes to my diet. My point was I didn't really change what I eat, but how I eat. I still hate certain vegetables like carrots, kale, brussel sprouts, etc. and just added more of the nutritionally equivalent and culinarily far superior vegetables I was already eating.

That's not willpower. That's looking things up in the USDA database and tweaking my existing recipes. Why force nasty carrots onto the plate when I can eat spinach, cantaloupe, pumpkin, sweet potato, etc.?

I guess I also didn't emphasize enough that I took things super slowly? Taking 5 years to do what I did is a really modest goal. I just wanted to manage risk with minimal change. This is the pareto principle in action.

If we're really going to argue over stats, the effects of GLP-1 is meaningless noise in comparison and probably way harder to commit to. I just wanted to eat good and not feel like shit all the time. Isn't that what everyone wants? What if instead of there being "one weird trick" or a "miracle drug", we consider that basic nutrition is simply misunderstood and full of hundreds of weird tricks that are proportionally much easier to implement and they're damn tasty too?

Not really, Ozempic face is the same face as one gets when starved of food for a longer period of time from low caloric diet that contains carbs. Ketosis on the other hand doesn't cause this unless one has almost no fat left as it doesn't switch body to the starvation mode. There are two modes the human body operates normally - insulin-driven, active when carbs are in the food, and ketone-driven, active when there is…

This is a bunch of pseudoscience. "Starvation mode" as people talk about it is generally nonsense - the exceedingly low bodyfat you mention for keto is the same place you would see it in a non-keto diet when we talk about actual starvation mode and not whatever you're talking about with a non-ketogenic diet. The only real difference when it comes to the biology here is that fat mobilization into glucose is significan…

I suspect you have no idea that your body has two independent energetic circuits - one driven by insulin and glucose, the other driver by ketones. Just please dump this to any decent LLm to give you ELI5. Muscles obviously need glucose for their best performance which is why strength training is not recommended during ketosis; OTOH ketosis is naturally muscle-sparing.

I'm not knocking anyone meeting their goals without GLP-1s. It's obviously possible in absolute terms - people have been making great body transformations for as long as we've had fat people.

But everything you did, plenty of people try to do and fail at it. You are making it sound like this is all it takes and that it's easy. It might have been for you! But it might not be for other people.

The fact of the matter is the overwhelming majority of people that are obese and go on GLP-1s have tried other interventions before and failed at them. ~70% of all obese people have tried to lose weight in general, ~50% have recurring attempts, and while I don't have stats to back it up I am confident that the sort of people who are willing to go and inject themselves every week are the sort of people that have tried to lose weight in other ways.

> probably way harder to commit to.

A subcutaneous injection once a week is nothing. Dealing with constant food noise? I could maintain that if the rest of my life was stress free, and that's how I would drop 30lb. Once stress came back? So did the weight. Because for me, rearranging food doesn't matter if I still can't stop thinking about it even if I'm not actually hungry.

I'm on reta. It does barely anything to suppress my appetite - physical hunger has never been my issue. And I can easily eat however much I want - most days I am below 2k calories, but Saturday was an annual event with friends and I'm sure between food and alcohol I was probably at 5k calories for the day. But what reta does, is absolutely murders my food noise. I don't think about food constantly. I don't go eat because I got bored. The only thing I have to commit to for it is, once a week, put a needle on my injector pen, twist the dial to the right dosage, poke it into a spot where I still have subcutaneous fat, depress the twist top. Once a month I reconstitute a new vial.

It certainly does not. To make that claim, the study would need a control group of people who had never taken the drug. They didn't have that: > Participants Veterans Affairs users with type 2 diabetes who started treatment with GLP-1RAs (n=132 551) or sulfonylureas (n=201 136), followed up for three years. Veterans Affairs users were defined as having at least two visits to Veterans Affairs and having used the Veter…

> They didn't have that So, why not? Seems very obvious to everyone here on HN that it's "kind of useless" unless they did have that, yet they didn't. What reason would there be for ignoring that?

They were testing what happens when you stop taking Ozempic compared to what happens when you don't stop taking it, and also what happens when you start taking it again.

Assembling a control group of people who have never taken Ozempic could be difficult. How do you control for the fact that people not on Ozempic are less likely to need Ozempic? You'd need to figure out some criteria by which to include and exclude patients before sorting by whether they take Ozempic or not, so you'd have a smaller sample size of people who are taking Ozempic.

Best not to allow scope creep.

> I suspect you have no idea that your body has two independent energetic circuits - one driven by insulin and glucose, the other driver by ketones.

I am fully aware - I have spent several years of my life following a ketogenic diet. None of that is relevant for "starvation mode" and insulin within that context. I was replying to your specific points - not providing an explanation on how ketosis works from end to end.

Unless you are claiming that your body just doesn't produce glucose/glycogen and insulin when in ketosis? Which would also be incorrect.

> Muscles obviously need glucose for their best performance which is why strength training is not recommended during ketosis;

Strength training should 100% still be done in ketosis/while following a ketogenic diet. It will be suboptimal compared to a regular training, but being in ketosis doesn't magically make resistance training optional if you want to be healthy.

> OTOH ketosis is naturally muscle-sparing.

It is not and the study links in my post show consistent data here. There might be an exception if you are an endurance athlete but that is based on far more limited data than the rest of the research. So... if you're a high level endurance athlete that is also somehow fat, keto might be a better option when it comes to sparing muscle, but for the rest of us, not the case.

I’m always kind of envious of the people who were able to lose weight on GLP-1 drugs. I lost a bunch of weight a few years ago, and still need to lose a lot more (430 lb -> 330, goal 240), but I fell out of the good habits for, well, no good reasons… Decided to try Ozempic and was on it for about 6 months. Didn’t do a single thing for my appetite unfortunately, even on the max dose. Sample size of one here, but if yo…

Try Fluoxetine 20mg, first 1 per day, later 2. Glp-1 doesn't work in stress related obesity.

It doesn't reduce heart attack and stroke. It reduces appetite, kind of, and gives you a sore stomach while making you shit yourself inside out. All this can, with care, help contribute to weight loss. Weight loss can reduce heart attack and stroke, but GLP-1 does not. You could also reduce heart attack and stroke risks by not eating crap and going for a walk every so often.

What is it about GLP1s that bring out the kooks who suddenly think diet and exercise are the only valid medical treatment? Is it a moral issue?

Yes, it's a moral issue.

What you need to understand is there are a lot of people where all they have is being skinny and appearing to be healthy. Without that, there's nothing left for them.

For a long time, there has been a moat that they can use as a justification for why they're better. They can say "well I work hard, I eat right, I put in effort!" The idea that others can achieve that without any of that means... well, they did it all for nothing. In their heads.

The dirty little secret? Many of them don't do any of that, it's just a delusion. Always has been. I'm skinny, you think I go to the gym? Fuck no! I should, but I don't. And I eat whatever I want.

But if a lot of people have to face the reality that their most redeeming quality is nothing of their doing, that would ruin them. Ruin them. They could just, like, get achievements or something but that's hard. Continuing the delusion is easy.

Everything is discipline. If you just always do the thing you’re supposed to you will win at life. People can’t always do the thing they’re supposed to so they supplement with drugs that help them do it: caffeine, amphetamine, SSRIs, GLP-1RAs and related drugs. In fact, everything is discipline. If you were disciplined enough to always put the basketball in the net from anywhere on the court you’d be Steph Curry. The…

Some things require talent like your examples, weight loss does not imho. The disparities in obesity and culture within country says it all.

Weight loss of course is helped by talent, because genetics are talent.

Metabolisms fluctuate, although granted not by much. But what really varies is your response to food. And it's not just genetics. It's food scarcity, early childhood, your environment.

The (maybe) sad reality is that there will be people skinnier than you will ever be who have put in zero effort. Nada. That's life. Just like there's people who can sing better than me off the rip and I took vocal lessons for 10 years. Life's not fair.

But the bright side is, I can drink and not be an alcoholic. Maybe they're just lazy or something. Or, maybe this mentality is one people feed themselves (ha) to feel better about the circumstances of their life.

Wouldn't we all like to believe we're the way we are because we're strong, brave, and hard-working?

Kind of a useless analysis if it doesn't compare the risk after stopping GLP-1s to the risk of NEVER taking GLP-1s in the first place. We probably don't know the numbers yet, but one can easily envision a scenario like: risk of CE without GLP-1 weight loss: 20%. Risk after taking GLP-1s for 2 years: 10%. Risk after stopping GLP-1s: 12%. "Your heart attack chance goes up 20% after stopping GLP-1s!!!"

It's not useless. It might be expected, but now it's more certain. This allows planning with it.

Scientifically it's valid, and good scientists and doctors would immediately pick up on the nuance.

The issue is shameless "science" reporting like this which packages up the results for non experts, without explaining the nuance because they know the sensational headlines will get more attention, and they know non-expert readers will get scared and share the article on places like HN or Facebook.

It's such an obvious play: find one doctor who'll make a loaded statement with the word "whiplash", write on this one study as if it's gospel truth, get everyone reading it as scared as possible. Throw in links to other emotional articles like "Can you die of a broken heart?" throughout the text to trigger secondary emotional reactions that will get confused with the main ones. Boom, social media sharing heaven, who cares if the science was valid or not?

And to be clear, the science underneath might be valid, probably even is, but it would need the expertise of someone who understands statistics and medicine to decide whether you should take action based on this or not.
