this seems to goes against almost everyone's experience and my own
-maybe we're bad at tracking calories from a decade or longer ago?
-eating too much and not knowing it?
-inactivity?
-stress du to family and job causes subtle changes that lead to weight gain
-change in gut bacteria?
-increased skin, organ, bone, and tendon/ligament mass? (non-muscle lean mass)
Some people balloon after the age of 20-30 or so, like during college or after. Look at your facebook feed of friends or family. this is way worse than just a few percent. Are scientists comepltelty oblivious to this for what is obvious to so many others?
Well if we’re going off opinion rather than tested hypothesis, my observation is that the reason people gain weight after college is gradual lifestyle changes leading to less sleep, alcoholic calories, sugar, more sitting, less exercise etc
I think a lot of people don't realise or perhaps consider that moving from school/University to the workplace can drastically change the amount of time you are moving throughout the day and your physical activity.
I used to work in a retail environment where I was on my feet all day in my early twenties, then I moved into an office environment. During both workplaces I exercised a lot but I absolutely noticed that I needed to be more conscious of what I am eating after having started working in an office.
"chronic stress aside, that decline in BMR mirrors almost perfectly the curves of PUFA consumption rates in the general population. Namely, as the BMR curve has steadily declined over the last 100 years the PUFA consumption rate curve has steadily moved upwards over time. Unless this trend of ever-increasing PUFA consumption is interrupted, I don’t see the decline of BMR flattening (let alone reversing) any time soon." eating massive quantities of highly processed seed oils that are ubiquitous in our food supply because they are much cheaper than "real" food is surely a contributor.

Science requires evidence. Plenty of folks don't gain weight as they age and others can't gain weight if they try. Anecdotal evidence is not sufficient for scientific endeavors. So we must create hypothesis and rigorously test them. Science is really the process of proving yourself wrong and then looking at what the data dictates. "Look at your facebook feed" isn't conclusive nor compelling as evidence to anything other than our crippling need to post everything on social media.
