I was actually shocked to see that I kept my weight stable during our 2020 trip to Hawaii (157, for you guys counting) and then as the Pandemic started we both dropped 4 to 5 pounds. We thought about it and because we were getting groceries via "Instacart" (still do), rather than wandering the aisles of "Market 32", we weren't picking up impulse-buy snacks to eat. Don't buy 'em, can't eat 'em.
So we've stayed +/- a couple of pounds for the past year. I'm currently up 2 (at 155) but that'll come down by next week as I see a couple of good riding days coming up and some yard work.
I usually drop 2 - 3 pounds on a ride and gain back 75% of that overnight so I can run it up or down 3-ish pounds per week, depending on food intake (more salads for lunch = down) or miles ridden (less miles = up). It's easily managed once you get used to the process and you know how much riding does what.
Just like deciding on transaxle gearing!
And yes, everyone should have an IRS rear, but those who don't can say that they're true to the original 356, right?
