Most likely depends on the kind of person you are, since obesity definitely was not curbed during the pandemic.

But yes, as someone who has been working remote even before the pandemic, I have had a similar experience. It's great being able to exercise between tasks, fast for most of the day, and overall have more control over my schedule. If I ever have to work in an office again, I know I will gain a minimum of 10 lbs. Group lunches, the desire of management to have you be there even if there's no meetings, no real ability to exercise during the day without being a weirdo, and commute time would take its toll. For me, that environment is evil.
