It’s an inevitable outcome of a culture so focused on age. I watch twitch streamers in their 20’s talking about how they’re old already. Narcissism isn’t just a social phenomenon spread online, I think it actively contributes to many public health concerns we’re seeing today.

I agree with your observation, but at the same time, I do think that what a lot of these people might be expressing is their observation of the disconnect between their socially implanted expectations (you're an adult when your 18/21! you are now -mature-), and their experience reality. Which is that for many (most?) people who go through the typical North American education pipeline through university/college (and I'm only making this limitation because that's my experience, and the experience of most of my friends), that looking back, they were definitely not "mature" at 18/21. They probably weren't even mature when they graduated undergrad or started their first full time job out of school.
Everyone has a different point, but they typically recognize somewhere in their 20s that 'oh wow, we keep changing and maturing'. And the first, most basic way to express this observation is with a pretty crude 'oh wow I'm old'. I think eventually, most people can move beyond that first reflexive observation.

So the results show that on average, metabolism is stable from 20 years onward. That means that there actually is a drop from 18 to 25 (it's there for men at least when you look at Fig 2). Now think about where most people will be anchoring their perception of "adult" from (it's going to be some value in that range). That means that there will absolutely be plenty of people who experience a real decline in metabolism in the years following their "personal adult threshold".
Now, that's a pretty small drop, so definitely the other life transition (probably starting an office job, living alone) will probably play an even larger part to any weight related changes. But even given a hypothetical case where someone kept the exact same activity level, the amount of metabolism decline over that period is probably small enough to delay the onset of any noticeable body composition change (like order of 10 pounds) for a few years, adding to the mid to late 20s experience.

#7No mention of how a persons lifestyle changes over that period though.
Surely there is a correlation to the causation?
The head-bone is connected to the neck-bone etc...
You cannot study figures in isolation and expect them to yield some meaningful results while ignoring the influence of other figures upon those results.
- Kids move around a lot, and they're still growing/developing
- Teenagers move more constructively i.e. sports, and they're still growing/developing
- Adults move a bit less, and have almost stopped growing/developing
- Older adults try do keep moving, but with other life responsibilities it gets hard to put the same time in
- Older adults become less and less bothered about moving
- Even older adults have acquired illness and injuries and can't move as much
Seems quite simple and obvious no? - Maybe...
Those that don't fit the mould have some other reason that makes then more of an outlier to the norm.
If life today didn't offer as much assistance as the past, we would all be a lot more healthy - not to mention more active, you know walking and manual work etc...
Not to forget that the abundance of food (good and bad) will have a bearing on the results. Maybe the older people that can't afford as much food are the outliers - and better benchmark.
Unless you are suffering from malnutrition, or you are overeating the wrong sort of food (good and bad) then your metabolism, unless affected by biological factors should be pretty stable.
Isn't this what being in homeostasis means?
Doesn't the body adapt to effects of S.A.I.D. - Specific Adaptations to Imposed Demands.

Such rumors are created and spread by people who want an excuse rather than a solution. This wont help them since they want to cling to their excuses, but it can help others ignore those rumors.

#9Another sobering result for the fitness industry, that convinces 30 year old men to be on TRT.
Convincing men at basically peak testosterone production to permanently impair their natural ability to produce it. It's awful. Not to mention the side effects of taking exogenous hormones e.g. damage to your liver...

I some times make the following observation:
When I was 15, I thought I had grown up quite a lot and looked back on my 10-year old self as someone who was just getting started.
When I was 20, I thought I had grown up quite a lot and looked back on my 15-year old self as someone who was just getting started.
When I was 25, I thought I had grown up quite a lot and looked back on my 20-year old self as someone who was just getting started.
When I was 30, I thought I had grown up quite a lot and looked back on my 25-year old self as someone who was just getting started.
Now that I'm 37, I think I have finally grown up and my 30-year old self was just getting started. But I recognize that my 42-year old self will probably look back on me and still see the same pattern.
