Done that myself a few times. In the present system, those who aren't able to walk, don't have to, and those that can, ought to be encouraged to, for the matter of public heath.

Their journey usually involves walking to the station, walking to the escalator, walking from the escalator to the train, and walking from the train to work.

That short escalator ride isn't a public health disaster.

It's more subtle than that. The difference in attitude between "I walk when it's unavoidable" and "I walk whenever I can because we spent a billion years evolving to do it and living in a city is very bad for my overall health and wellbeing".

There was a woman who became obese following a transplant of gut flora.

For 50% of the population? I call shenanigans.
