Without more details if be inclined to blame "almost identical" as the culprit (not an expert): Making all your meals 5% bigger would cause a weight gain of nearly 10lbs/yr, and the kind of switch in diet that can happen naturally with age (especially including eating out more with friends) can make it hard to spot incremental changes. Moreover, a lot of exercise doesn't actually do much for weight loss (it's still i…

> Without more details if be inclined to blame "almost identical" as the culprit (not an expert): Why? I mean, why do people find the idea of older people needing different diet due to body changes related to age so unbelievable? There are many changes related to age - how quickly injuries heal, how quickly you recover from something physical or tiring, how much or well you sleep. Your heartrate is slowly changing wi…

> Why?

Because it's much more likely that they're one of the who can't estimate calories in/out well than that they're an outlier with a significant metabolic drop in some small number of years, especially given that small misestimations are large enough to yield the observed behavior. Maybe there's something else going on, but "without more details" it wouldn't be the first place I'd look.

> older people needing different diet

Absolutely! I hope nobody took away opposing statements to that from what I said. The double whammy of needing fewer calories and being less equipped to absorb vitamins and whatnot necessitates a significant change in diet with age. I was only commenting on this one person's experience aging just a few years in the middle of their life.

> walking

> That is not how this works tho.

Especially for walking, that's exactly how it works. Walking builds negligible muscle mass, and everything else you've mentioned (aside from perhaps impacts on hunger), adds up to well under a 5% error in calorie estimates -- well under the noise floor from applying a general purpose calorie estimate to any one specific person.

It is known that training a deep neural net consume much more energy than inferencing it.

I would like to see a citation for this claim as I suspect it is not true

It takes hours or days or weeks to train a net. It takes milliseconds or seconds to run inference.

Interesting, seems there's always a tradeoff

This seems almost unbelievable to me. Almost everyone I know, with a handful of exceptions I can think of, had a dramatic change in what I can only say was metabolism at 30 declining steeply to 40. I can tell you personally my ability to lose weight when exercising daily has decreased significantly since 30. If it’s not metabolism, then what? Diet and exercise are almost identical.

For me, 5% larger meals just means 5% more poop

> Central to their findings was that metabolism differs for all people across four distinct stages of life.

There’s infancy, up until age 1, when calorie burning is at its peak, accelerating until it is 50 percent above the adult rate.

Then, from age 1 to about age 20, metabolism gradually slows by about 3 percent a year.

From age 20 to 60, it holds steady.

And, after age 60, it declines by about 0.7 percent a year.

Gotta make way for the homo-superior.

Otoh, if you watch 9 year old boys on the playground, you would conclude that Neanderthals walk among us. Jeesh.

Friend, I think you missed the David Bowie reference.

The song is Oh, you pretty things.

This is very important for any water related activities: many kids drowned because of this. Jumping, screaming and laughing in the water - the next moment gone. You have to pay attention. I do not mean, being overprotective, just pay really attention to them and you should notice, when they are about to reach their limits.

one tip is to use a floating life jacket. obviously you still need to constantly watch them, but using safety gear is a good idea
