here's a recent example of having past the point no return, i think.

since the pandemic started, i have been working from home. i used to be quite active at work, on my feet and walking a bunch. i didn't count, but easily 10,000+ steps a day. now, for the last year almost, my activity has reduced dramatically - down to maybe 100s of steps some days! this has no doubt contributed to the 60 lbs i have put on over the last year.... of course, access to snacks all day has helped, too.

last week after seeing how winded i got walking up two flights of stairs, emily (my gf) brought up the subject of my inactivity... and i agreed, for my health i needed to try to become more active.
so i went for a long walk on the weekend, just around my neighborhood. i walked for an hour with two breaks to catch my breath, where i sat for maybe 10 minutes each time.
on the way home i passed a bakery... so i stopped in and brought home a treat: a half-dozen super-sized chocolate cupcakes with icing! i figured i earned the extra calories from all the walking, and i would share them at home for dessert at dinner...
so i had one, and it was soooo good! i couldn't resist, so i had another... anyway, to make a long story short, long before dinner all of the cupcakes were gone.

i just couldn't resist!
the weather is getting nicer here, so i am sure em and i will be walking more, but somehow i don't think i will be losing much weight.
